SYDNEY (Reuters) - Thousands of Australian students walked out of class on Friday to join rallies demanding stronger action to rein in climate change, which they said is contributing to the country's bushfire crisis.
Australia has been battling wildfires for weeks, which have killed at least four people, burnt about 2.5 million acres (1 million hectares) of farmland and bush and destroyed more than 500 homes.
The rallies, in Sydney and other major Australian cities, were the first in a series of protests by students across the globe demanding governments do more to protect the environment. The protests come ahead of the annual U.N. climate conference that starts in Madrid on Monday.

Holding home-made signs, including "The climate is changing, why aren't we?", protesters in Sydney accused the government of inadequate action in addressing Australia's bushfire crisis. Smoke from the bushfires in New South Wales state formed a haze overhead.

"Our government's inaction on the climate crisis has supercharged bushfires," said 18-year-old Shiann Broderic, one of the event's organisers, whose home was destroyed in a bushfire.
"People are hurting. Communities like ours are being devastated. Summer hasn't even begun."
Australia's Prime Minister Scott Morrison has previously rejected suggestions his government is not doing enough to address climate change.
Australia has pledged to cut carbon emissions by 26% from 2005 levels by 2030, but recent data shows emissions are unchanged.
However, data released on Friday showed Australia's greenhouse gas emissions were roughly unchanged in the 12 months ended June.
The release of the data came as firefighters continued to battle more than 150 blazes still alight across the country that has left more than 5 million people residing in Sydney struggling under hazardous air pollution that has lingered for much of the last week.
While a cool change has eased the threat of more fires, Australia's Bureau of Meteorology on Thursday said much of the country will suffer from continued hot and dry conditions this summer, increasing the chances of more bushfires.

'Our House Is On Fire': EU Parliament Declares Climate Emergency

The European parliament has made a symbolic move to declare a global climate emergency in a bid to force member states into action.

A "climate emergency" has been declared by the European Union's legislature in a symbolic bid to push the issue as high as possible on the agenda of the EU's executive team.
The parliament in Strasbourg, France, voted by 429 to 225, with 19 abstentions, to call the increasing environmental challenges linked to climate change an emergency.
Renew Europe MEP Pascal Canfin, who initiated the move, said it made Europe "the first continent to declare a climate and environmental emergency".
Mr Canfin said the parliament is meeting the expectations of European citizens.

But environmental campaigners said the declaration was not backed by sufficient action.
“Our house is on fire. The European parliament has seen the blaze, but it’s not enough to stand by and watch,” said Greenpeace’s EU climate policy adviser, Sebastian Mang, shortly before the vote.
The EU has long been at the forefront of the global climate debate, a role that has been reinforced since the United States pulled out of the Paris climate agreement.
With increasingly erratic weather patterns from wildfires in Australia to floods in Europe being linked to climate change, governments are under scrutiny to find urgent solutions at the United Nations' summit in Spain on December 2-13.
Dissenters objected to the word "emergency", saying it was too drastic, and "urgency" would suffice.
Frustrated scientists and activists warn that despite such declarations, action is still lagging to hit the Paris Agreement target of curbing emissions enough to keep temperature rises to within 1.5-2 degrees celsius of pre-industrial levels.
However, the EU parliament's vote should help shape policies for the bloc's incoming executive head, Ursula von der Leyen, who assumes office on December 1.
The 28-nation EU is the first multilateral bloc to call a climate emergency, but joins numerous individual countries and cities from Argentina and Canada to New York and Sydney.

How China Moved From Leader To Laggard On Climate Change

Financial Times - Leslie Hook

When the economy was growing robustly, Beijing saw stronger environmental policies as core to its economic transformation. Today, with growth at its slowest pace since the early 1990s, that has changed. The FT reports.

Baoding, China | The smoggy city of Baoding is known for two things: donkey burgers, and solar panels. An industrial centre just south of Beijing — 45 minutes via high-speed rail — the city’s high-tech zone styles itself as “Power Valley” because it is home to so many solar manufacturers.
But for Vincent Yu, deputy general manager at Yingli Solar, one of the first renewables companies to set up in the city, business has been difficult lately. “These last two years, there has been a lot of pressure. The subsidies for solar projects have fallen,” Mr Yu says. New solar installations in China — running at 53 gigawatts in 2017 when demand peaked — will be about 40 per cent lower this year, he estimates.

The photographs in his office show Yingli in its glory days a decade ago. Sales were surging and the company spent millions sponsoring the 2010 and 2014 football World Cup tournaments. Yingli was the world’s largest solar-panel maker in 2012 and 2013, exporting all over the globe and celebrated in China as a national champion. Its huge factory campus in Baoding still nods to that status, with a spacious museum dedicated to the company’s history as a solar pioneer.
Today Yingli is insolvent. It has been defaulting on debt payments since 2016, and in 2018 it was kicked off the New York Stock Exchange because its market capitalisation had sunk below the minimum $US50 million ($74 million) threshold. Although Yingli still makes solar panels, its factories operate at a loss and the most valuable asset it has left is the land underneath them. Some question how Yingli is still operating. But analysts believe the political connections of its founder may have helped stave off creditors.
The company is the highest-profile casualty of a change in policy that is being felt across the renewable energy sector in a country once celebrated as the world’s clean energy champion. Chinese investment in clean energy is plummeting — down from $US76 billion during the first half of 2017, to $US29 billion during the first half of this year.

For the annual UN climate talks, starting next Monday, that is alarming.
Concerns over the impact of climate change have never been higher. But the gap between what countries should be doing, and what they are actually doing — pumping rising levels of carbon dioxide into the air — has never been greater. With the US withdrawing from the Paris climate accord, an increasing amount of attention is on China.

The country is both the greenest in the world, but also the most polluting. It has more wind and solar power than anybody else, yet it is also the world’s biggest builder of new coal plants. Last year, its emissions hit a record high, accounting for more than half of the global increase in energy-related CO2 emissions in 2018, according to the International Energy Agency.
This year, Chinese emissions are expected to grow about 3 per cent from 2018.
“Everything is at stake for the planet, because the Chinese economy is so much bigger than any other,” says Adair Turner, chair of the Energy Transitions Commission. “Even the whole of Europe is considerably less than Chinese emissions.”
He points to China’s current pledge, that its CO2 emissions will peak by 2030, and says it is nowhere near ambitious enough. “Let’s be clear, if that was all China ever did, then we are on the path to climate disaster,” says Lord Turner, who is lobbying for China to consider a target of net zero emissions by 2050. “That is true of all the [countries that have made pledges under the Paris accord] . . . everyone has always known there would have to be very significant improvements, to get us anywhere close to 2C.”

The Paris climate accord, of which China is a signatory, pledges to limit global warming to well below 2C. But that goal looks increasingly out of reach. The world is on track for 3C of global warming by the end of this century, if current trends continue. That would mean higher sea levels of as much as 1m, threatening more than 600m people in low-lying and coastal areas, according to a recent report from the UN’s Intergovernmental Panel on Climate Change.
The climate pact is under attack from many sides, and the US is withdrawing from the agreement entirely, on President Donald Trump’s orders. Fraying multilateralism has further eviscerated the climate accord, which lacks any enforcement mechanism. China — distracted by a slowing economy, the US trade war and protests in Hong Kong — is not the only reason why the planet is on course for devastating climate change, but it is near the top of the list.

“The general momentum on climate and environment issues has been declining [in China],” says Li Shuo, senior global policy adviser at Greenpeace. Climate change has become a lower priority for Beijing. “There is less space for the green agenda,” he says.
China’s investment in renewable energy fell 39 per cent in the first half of this year, compared with the same period in 2018, according to data from Bloomberg New Energy Finance. Beijing yanked subsidies for solar panel projects in the middle of last year, and is shrinking those for wind, causing an abrupt shift.
“This is probably a low point,” says Li Junfeng, a senior renewable energy policymaker and head of the National Centre for Climate Change Strategy Research, part of the government planning ministry. “The new policy is not in place yet, and the old policy [of subsidies] has been stopped.”
Five years ago, when the economy was growing robustly, Beijing saw stronger environmental policies as core to its economic transformation away from energy-intensive heavy industry. Today, with the economy growing at its slowest pace since the early 1990s, that has changed.

“The highest political priority in China is trying to stabilise the economy,” says Kevin Tu, an energy economist who previously led the China desk at the IEA. “Anything else, including environmental protection, especially climate change, will have to make some room for these political priorities.”
On paper, China’s climate targets have not changed: Beijing has pledged that its carbon dioxide emissions will peak by 2030, and that it will draw 20 per cent of its primary energy from non-fossil sources by that same date.
Yet that promise would allow China to keep increasing its emissions for the next decade, with devastating implications for the planet. Its investments in the Belt and Road Initiative, under which state banks have earmarked more than $US30 billion to build coal-fired power plants in other countries, is also adding to global emissions.

China’s participation in the Paris climate pact in 2015 was heralded as a great victory by activists. Convincing Beijing to set climate targets was a top priority for the Obama administration. But baked into the negotiations was an expectation that China would achieve its emissions target much earlier than 2030.
Next year will be crucial, as countries that signed the Paris accord are supposed to submit enhanced targets — but the mood in Beijing makes a tougher climate goal less likely for China.

Mr Li says deteriorating relations between the US and China — along with the unrest in Hong Kong — have helped fuel a growing nationalist sentiment and a broader anger at the west.
One of the targets of this nationalist ire has been Greta Thunberg, the Swedish teenage activist who is revered as a climate hero in some parts of the world. “Many netizens see [Greta] as representing the general liberal western agenda,” says Mr Li. “There is this larger perspective that the west is ganging up against China.”
At the same time, coal appears to be again in the ascendant with Li Keqiang, China’s premier, last month identifying it as a priority area. China remains the world’s biggest producer. Many see this as part of a growing focus on energy security in Beijing, a result of Chinese leaders being spooked by deteriorating relations with the west. “Energy security anxiety is a blessing for the coal [sector] in China,” says Mr Tu.
Policymakers are also focused on keeping the cost of power cheap to help stimulate the economy, so from January the price of electricity from coal-fired power plants, which is centrally regulated, will be allowed to fluctuate, and is expected to fall.



These factors have compounded the pain for the renewable energy industry. After benefiting from generous subsidies for more than a decade, Beijing axed solar subsidies without warning last year. The payments due have created a deficit of around Rmb200b ($41.3b) in the renewable energy development fund that was paying out the subsidies.
Frank Haugwitz, founder of Asia Europe Clean Energy (Solar) Advisory in Hong Kong, says the subsidies contributed to a solar surge that exceeded the government’s expectations, triggering the sudden cut.
The dice are now loaded in coal’s favour. The new policies for renewable energy are focused on grid parity — only building wind and solar projects that can compete with the price of coal. Yet with coal power prices dropping, and a glut of new coal-fired power stations coming online, it may be challenging for wind and solar to compete.
In the wind industry, there has been a rush of projects this year as developers try to capture the last of the subsidies.


The diplomatic pressure on China to improve its climate targets has been played out in public. During a state visit from Emmanuel Macron, the French president, earlier this month, both sides issued a joint declaration, vowing that the Paris climate deal was “irreversible”, and promising new climate targets aimed at the middle of the century.
Chinese policymakers such as Li Junfeng say the pressure is misplaced, as China is likely to exceed existing climate targets, even if it does not officially adopt new goals. “Now that the US has withdrawn from the Paris agreement, the entire global response to climate change is shifting,” he says. “We have to be realistic . . . There’s no point in being in a rush.”
He also points out that China has achieved, and far surpassed, most of its previous climate targets. A pledge to cut carbon intensity — the amount of carbon produced per unit of GDP — by between 40 and 50 per cent by 2020, compared with 2005 levels, was achieved three years early. It also overachieved on its targets for solar installations, although this runaway growth led to the subsidy deficit.



For many years, action on climate change was the one area that Beijing and western capitals could usually agree on. Even the most hawkish western politician would hold up China’s climate record as an example to be praised.
But that may be changing. “It is going to sour for sure, if China doesn’t move in the right direction, quickly enough,” says Todd Stern, the chief US negotiator for the Paris agreement, who adds there is simply “less leeway” now in terms of global emissions. “We can’t possibly do what we need to do, unless China is doing quite a bit.”
“We are sort of entering a new world now . . . It is not just a sense of urgency, it is the math. Do the math, and you will see whether we are doing enough,” says Mr Stern. “The Paris agreement is going to rise and fall, on the level of political will in constituent countries. That has always been true.
“The fault is that there is a lack of political will in virtually every country, compared to what there needs to be.”

UNEP Says Global Emissions Must Be Cut By 7.6% Every Year For Next Decade

RenewEconomy -

The United Nations Environmental Programme (UNEP) has warned global greenhouse gas emissions must fall by at least 7.6% each year over the next decade or risk missing the 1.5°C temperature goal of the Paris Agreement.
The UNEP’s Emissions Gap Report also highlights seven G20 member nations that are falling well behind their Paris Agreement commitments, including Australia, Japan, South Korea, and the United States.
The UNEP’s annual Emissions Gap Report compares current greenhouse gas emissions against where emissions need to be and where they are heading.
The latest 2019 report shows that things are not going well, and that even if all current unconditional commitments under the Paris Agreement are implemented, temperatures are expected to rise by 3.2°C. Such a dramatic rise in temperature by the end of the century will result in wider-ranging and more destructive climate impacts across the planet.
“For ten years, the Emissions Gap Report has been sounding the alarm – and for ten years, the world has only increased its emissions,” said UN Secretary-General António Guterres. “
There has never been a more important time to listen to the science. Failure to heed these warnings and take drastic action to reverse emissions means we will continue to witness deadly and catastrophic heatwaves, storms and pollution.”



“Our collective failure to act early and hard on climate change means we now must deliver deep cuts to emissions – over 7 per cent each year, if we break it down evenly over the next decade,” added Inger Andersen, UNEP’s Executive Director.
“This shows that countries simply cannot wait until the end of 2020, when new climate commitments are due, to step up action. They – and every city, region, business and individual – need to act now.”
“We need quick wins to reduce emissions as much as possible in 2020, then stronger Nationally Determined Contributions to kick-start the major transformations of economies and societies. We need to catch up on the years in which we procrastinated,” she added. “If we don’t do this, the 1.5°C goal will be out of reach before 2030.”
The report unsurprisingly highlighted the role of G20 member nations, which together account for 78% of global greenhouse gas emissions, and which are “collectively” on track to meet their limited 2020 Cancun Pledges.
However, seven countries – Australia, Brazil, Canada, Japan, South Korea, South Africa, and the United States – are currently not on track to meet their 2030 nationally determined contributions (NDC) commitments, and it is “not possible to say” for a further three countries.
Further, and to make matters worse, six countries – Canada, Indonesia, Mexico, South Korea, South Africa, the United States – are currently on track to miss their Cancun Pledges, while Argentina, Saudi Arabia, and Turkey have not made any 2020 pledges.
In all, only five G20 member nations have committed to a long-term zero emissions target.
The report notes Australia is proposing to “carry forward their overachievement from the Kyoto period to meet their 2020 Cancun Pledges” thanks in part to the Government’s decision to count cumulative emissions between 2013 and 2020.
It notes that if this “carry-forward” approach is not taken, Australia will not even achieve its 2020 pledge.
The authors of the report specify that “it appears that the Australian Government intends to use carry-over permits from the Kyoto Protocol to do so, and uses a carbon budget approach that accounts for cumulative emissions between 2021 and 2030 in order to assess progress against its NDC.”
Australia is also one of the seven countries deemed as requiring “further action of varying degree to achieve their NDC” – a fact not helped by “the re-election of Australia’s conservative Government in May” which has cemented the fact “there has been no recent material change in Australian climate policy.”
“The dropping of the proposed National Energy Guarantee in 2018 and that the renewable energy target will not be raised for years after 2020 up to 2030 … leaves Australia with no major policy tool to encourage emission reductions from the electricity sector in the short to medium term,” write the authors of the UNEP Gap report.
Looking at the overall picture, the UNEP shows that, in the short-term, developed countries will have to reduce their emissions faster than developing countries – a crucial point which will serve to undermine or clash with many conservative talking points around the world.
But the report also says that all nations must substantially increase ambition in their NDCs in 2020 and follow up with ambitious and long-term policies and strategies to implement them.

'Dangerously Close': Tipping Points May Trigger Climate Cascade

Sydney Morning HeraldPeter Hannam

The planet faces a "global cascade of tipping points" that could lead to an abrupt shift to a warmer world and cause huge disruption to human societies and ecosystems unless nations slash their greenhouse gas emissions.
The warning is contained in an article appearing on Thursday in Nature. The authors identified several "large-scale discontinuities" in the climate system that may be underway, and which could trigger further warming.

Countries need to cut their greenhouse gas emissions much faster than agreed under the Paris Climate Agreement, the UN has warned, or risk "wide-ranging and destructive climate impacts." 

Countries need to cut their greenhouse gas emissions much faster than agreed under the Paris Climate Agreement, the UN has warned, or risk "wide-ranging and destructive climate impacts."
"If damaging tipping cascades can occur and a global tipping point cannot be ruled out, then this is an existential threat to civilisation," the scientists said.
The ice sheets in West Antarctica may be one of several cryosphere tipping points that were "dangerously close", if they hadn't already begun an irreversible retreat. These alone would raise sea levels by three metres if melted.

Those in the Wilkes Basin of eastern Antarctica may be similarly unstable, with another four metres of potential sea-level rise if they disintegrated.
"The time to act decisively is now. Any more dithering is irresponsible, as the risks are increasing year by year," said Stefan Rahmstorf, head of Earth system analysis at Germany's Potsdam Institute for Climate Impact Research, and one of the authors.
"But even once we pass a tipping point – and probably we have done so for the West Antarctic Ice Sheet – we will need to reduce emissions even more urgently, to slow down the unfolding effects and to avoid passing further tipping points."

Running AMOC
The interconnected nature of the giant mixing processes that distribute heat around the world's oceans is a key reason why one region's changes could reinforce other shifts.
For instance, the melting of Greenland's ice sheets is driving an influx of fresh water into the North Atlantic, slowing the Gulf Stream – also known as the Atlantic Meridional Overturning Circulation (AMOC) – by 15 per cent since the middle of the 20th century.
Another outcome is a further heating of the Southern Ocean, resulting in more Antarctic ice melt.

Other effects include drought for the Sahel region because of disruptions to the West African monsoon, and worse fires in the Amazon as that region dries out.
Will Steffen, an emeritus professor at the Australian National University and another author, said some of the processes would add to warming by releasing more carbon dioxide or methane to the atmosphere.
Amazon dieback alone had the potential to release about 90 billion tonnes of CO2 while boreal forests could add another 110 billion tonnes. Even without including the methane, emissions from melting permafrost could total 100 billion more tonnes of CO2, the report said.

By contrast, humans directly contribute to about 40 billion tonnes of CO2 a year. We also have a total emissions budget of 500 billion tonnes if the world is to have a 50:50 chance of hitting the Paris climate target of keeping warming to 1.5 degrees.
Entire ecosystems, such as the Great Barrier Reef, were also facing tipping points. Half the reef's coral cover had been lost in recent bleaching and only a tiny fraction would remain if warming reached 2 degrees, the paper said.

Australia is among the most exposed nations given it is already exposed to droughts and heatwaves.
"The warning signs are clear," Professor Steffen said. "It will be a much tougher climate for us to live in."

The risk was not of runaway global warming but rather of a world stabilising at perhaps 5 degrees warmer.
"The schoolchildren are right," he said. "We indeed have a climate emergency, and an emergency-level response is now needed to ensure that we don’t activate the tipping cascade."

Climate Emergency: World 'May Have Crossed Tipping Points’

The Guardian

Warning of ‘existential threat to civilisation’ as impacts lead to cascade of unstoppable events
‘Part of the west Antarctic ice sheet may be in irreversible retreat,’ said one of the researchers. Photograph: Handout/AFP/Getty Images 
The world may already have crossed a series of climate tipping points, according to a stark warning from scientists. This risk is “an existential threat to civilisation”, they say, meaning “we are in a state of planetary emergency”.
Tipping points are reached when particular impacts of global heating become unstoppable, such as the runaway loss of ice sheets or forests. In the past, extreme heating of 5C was thought necessary to pass tipping points, but the latest evidence suggests this could happen between 1C and 2C.
The planet has already heated by 1C and the temperature is certain to rise further, due to past emissions and because greenhouse gas levels are still rising. The scientists further warn that one tipping point, such as the release of methane from thawing permafrost, may fuel others, leading to a cascade.
The researchers, writing in a commentary article in the journal Nature, acknowledge that the complex science of tipping points means great uncertainty remains. But they say the potential damage from the tipping points is so big and the time to act so short, that “to err on the side of danger is not a responsible option”. They call for urgent international action.
“A saving grace is that the rate at which damage accumulates from tipping could still be under our control to some extent,” they write. “The stability and resilience of our planet is in peril. International action – not just words – must reflect this.”

Scientists' warning: a cascade of climate tipping points is possible

Prof Tim Lenton at the University of Exeter, the lead author of the article, said: “We might already have crossed the threshold for a cascade of interrelated tipping points. The simple version is the schoolkids [striking for climate action] are right: we are seeing potentially irreversible changes in the climate system under way, or very close.”
“As a scientist, I just want to tell it how it is,” he said. “It is not trying to be alarmist, but trying to treat the whole climate change problem as a risk management problem. It is what I consider the common sense way.”
Phil Williamson at the University of East Anglia, who did not contribute to the article, said: “The prognosis by Tim Lenton and colleagues is, unfortunately, fully plausible: that we might have already lost control of the Earth’s climate.”
The new article comes as the UN warns action is very far from stopping global temperature rise, with the world currently on track for 3C-4C. The commentary lists nine tipping points that may have been activated.

“We have this alarming evidence that part of the west Antarctic ice sheet may be in irreversible retreat,” said Lenton. “All the signals are that it is.” A similar situation appears to be occurring at the Wilkes basin in east Antarctica. The collapse of these ice sheets would eventually raise sea level by many metres.
The massive Greenland ice sheet was melting at an accelerating rate, the scientists said, while Arctic sea ice is shrinking fast. “Permafrost across the Arctic is beginning to irreversibly thaw and release carbon dioxide and methane,” they said.
The Gulf Stream current in the Atlantic, which warms Europe, has also slowed by 15% since the mid-20th century. “That is just about in the range of natural variability, but it is also hard to rule out that it is part of a longer downturn,” Lenton said.
The scientists report that 17% of the Amazon rainforest has been lost since 1970. The tipping point, where loss of forest leads to it drying out, could lie in the range 20%-40%, they said. In temperate forests, especially in North America, heating has triggered more fires and pest outbreaks, potentially turning some regions from a sink for carbon to a source. In the tropics, corals are predicted to be wiped out by 2C of heating.
A cascade of tipping points could occur because, for example, the melting of Arctic sea ice amplifies heating by exposing dark ocean that absorbs more sunlight. That may increase the melting of Greenland ice and permafrost areas. “Multiple risks can interact, with one change reinforcing another, and with warming of just a degree or two sufficient to result in dramatic cascading effects,” said Williamson.
Prof Martin Siegert, at Imperial College London, said: “The new work is valuable. They are being a little speculative, but maybe you need to be.” He pointed out that the extremely rapid rate at which CO2 was being pumped into the atmosphere was unlikely to have ever occurred on Earth before. “It may mean that tipping points can occur in unexpected ways as there is no geological precedent for this rate of CO2 change.”
The article reports that preliminary results from the latest climate models suggest global heating will be greater than expected, increasing the risk of tipping points. Prof Piers Forster, at the University of Leeds, disagreed on that point. However, he added: “I completely endorse their call for action. Although possibly low probability, the risks they identify are real.”
Lenton said action would still have real benefits, by slowing the impacts and giving more time for people to adapt. He said: “This article is not meant to be a counsel of despair. If we want to avoid the worst of these bad climate tipping points, we need to activate some positive social and economic tipping points [such as renewable energy] towards what should ultimately be a happier, flourishing, sustainable future for the generations to come.”

Women In Climate Change Hotspots Face Greater Burdens When Under Environmental Stress

ABC ScienceSuzannah Lyons

Environmental stress can hamper women's ability to adapt in climate change hotspots, like Bangladesh. (Getty Images: Zakir Hossain Chowdhury/Barcroft Media)
Key points
  • After about 100 people made a two-hour hike up a volcano, children installed a memorial plaque to the glacier
  • The plaque, which notes the level of heat-trapping carbon dioxide, warns "we know what is happening and what needs to be done"
  • Iceland's PM says climate change will be a priority when Nordic leaders meet in Reykjavik on Tuesday
Climate change has a negative impact on women's ability to make meaningful decisions in their lives, according to new research looking at climate change hotspots in Africa and Asia.
Even when household structures, social norms and legal frameworks support women's agency, environmental stress and its repercussions can still increase the burdens they face compared to men.
The study, published in Nature Climate Change on Tuesday, analysed 25 case studies from African and Asian climate change hotspots to identify factors that affect women and their ability to adapt.
The researchers wanted to move away from basic climate change and gender analyses that present women as victims, said social scientist and lead author of the paper Nitya Rao of the University of East Anglia.
"What we see in our fieldwork is that women are not sitting there doing nothing. Actually they're quite active in trying to do a lot of things in order to adapt," Professor Rao said.
However, Professor Rao and her co-authors found that unless social supports like childcare, health services or minimum wage conditions were in place, it was very hard for women to actually adopt climate change solutions.
This is due to the disproportionate disadvantages women already face, and the extra burdens environmental stress can bring, particularly in societies that mostly rely on agriculture.
These can include gendered labour division, limited access to land, limited access to credit and the reproductive burden women carry, both in bearing and looking after children, Professor Rao said.
Adding to that, women are often left to manage their households alone if their male partners need to migrate to look for work.
"When you double the work of a woman and … she's not able to do any more work, that's a good reason for not taking up climate-resilient rice for instance," Professor Rao said.

  11,000 scientists declare 'climate emergency'
The study addresses a really important gap in our understanding of the gender dimensions of vulnerability to climate change, said human geographer Fiona Miller of Macquarie University, who wasn't involved in the research.
"They might have more responsibility to manage money, but they don't necessarily have more power to make decisions concerning that money," Dr Miller said.
In a positive case study from Nepal, women were able to improve their agency by forming a cooperative.
However, low-caste women were excluded from that cooperative.
"I think one of the wider findings of the work is that yes, we need to focus on gender equity, but we also need to …. focus on those women who are especially marginalised due to caste or class or ethnicity," Dr Miller said.

So, does that mean climate change is sexist?

The research really highlights the social impact of climate change, said Climate Council CEO Amanda McKenzie.
"What it's saying is that the people who are most vulnerable will suffer the most, and the most quickly," she said.

  How does climate change affect our health?
And yet, while organisations like Plan International and Marie Stopes International have position papers on gender and climate change, there isn't as much awareness of it in the broader public sphere.
"I think that the social dimensions of climate change haven't been adequately discussed," Ms McKenzie said.
"We're still moving beyond understanding climate as an environmental issue, to understanding it's a human issue [with a] whole range of direct human costs."
These can be the immediate risks facing people in the middle of a natural disaster for example, or the longer-term impacts that adapting to climate change can have on people's health and the resilience of their communities.
While climate change itself is not sexist, the nature of gender and power relations means climate stress can exacerbate problems that are already there.
"Whenever there is something occurring that is damaging to our society, it tends to hurt women, people of colour more," she said.
Ms McKenzie believes there isn't enough discussion about who is paying the price and who is profiting from climate impacts.
"I think there's a sexism element there too, because the people who are profiting the most would tend to be powerful men in Western countries."

Is this research relevant to Australia?

While the research focused on climate change hotspots in Africa and Asia, Professor Rao said it also has relevance for other parts of the world.
"[In] labour markets across the world we know there is a gender wage gap," she said.
And that includes Australia.
Talking about how climate change affects women's ability to feed their families is something we can relate to, said geographer Celia McMichael of the University of Melbourne, who wasn't involved in the work.
"When you read of other people trying to cope with climate variability, I think it's something we can increasingly empathise with because that is not removed from our lives in Australia [any more]," Dr McMichael said.
"Yeah, we can turn on the AC but we still are dealing with bushfires and things."
One of the findings the paper identifies is that public institutions are really important in terms of supporting households and communities to respond to environmental stresses, said Dr Miller, and we need to have gender equity within those response organisations.
"If you're thinking about the fires that we're dealing with now across Australia, and particularly in New South Wales, we do tend to see an overrepresentation of men in emergency response organisations," she said.
"If we're thinking about issues around evacuation, for example, men and women may respond to that challenge in quite different ways.
"If you have emergency response agencies that are sensitive to those gendered issues … then you can give advice and support so that people can make appropriate decisions."
Ms McKenzie said the importance of educating women and girls has already been shown to be an important climate change solution by organisations such as Project Drawdown.
"I think that these solutions that involve women and girls and education, maternal health etc. are really important," she said.
"Not just for resilience, but also in getting down emissions in the first instance."

(AU) The Most Important Issue Facing Australia? New Survey Sees Huge Spike In Concern Over Climate Change

The Conversation

While most Australians still view the economy as the most important issue facing the country, a new survey released today shows climate change is rapidly becoming a major concern, as well.
Now in its 12th year, the Scanlon Foundation survey is the largest- and longest-running poll tracking public opinion on social cohesion, immigration, population and other issues in Australia. The 2019 survey was administered by telephone and the internet in July-August to a representative sample of 3,500 respondents.
The largest change in the survey from 2018 to 2019 came with the open-ended question: “What do you think is the most important problem facing Australia today?”
Both years, the economy ranked as No. 1. But this year, climate change jumped to a clear second with the equal-largest increase from one year to the next, up from 10% to 19% in our telephone-administered survey and from 5% to 17% in the self-completed online survey.

As would be expected, there were major variances in the responses depending on demographics.
Nearly half (43%) of those aged 18-24 viewed climate change as the biggest problem facing Australia, compared to 12% of those aged 35-44 and just 8% of those over the age of 75.
The responses also varied by state – 20% of Victoria residents and 18% of NSW residents said climate change was the biggest problem, compared to 8% in Western Australia.
And there was a stark difference depending on political affiliation, with 54% of Greens voters saying climate change was the most important issue, compared to 21% of Labor, 7% of Coalition and just 3% of One Nation voters.

Less worry about immigration numbers
Last year, immigration was a major political issue in Australia. Several polls, variously worded and with different approaches to sampling, found majority support for a reduction in the numbers of immigrants permitted into Australia each year.
Prime Minister Scott Morrison said his government was listening to the public’s concerns and responded with changes, including a reduction in the annual immigration target.
This year, however, there is evidence of a decline in public concern.
The percentage of people who agreed the immigration intake was too high in the annual Lowy Institute poll fell from 54% in 2018 to 47% in 2019.
And in our poll, the proportion of those who agreed with a reduction in the number of immigrants fell marginally from 43% in 2018 to 41% in 2019 in our interviewer-administered survey and from 44% to 41% in the self-completed version.

Endorsement of the value of immigration
There is continuing endorsement of the value of immigration by a substantial majority of Australians.
In the self-completed version of this year’s survey, 76% agree that immigration is good for the economy, 78% agree that immigration “improves Australia by bringing new ideas and cultures” and 80% agree that multiculturalism has been good for Australia.
Since 2015, the survey has tested public support for immigration restrictions on the grounds of race, ethnicity or religion, which have been advocated by minor right-wing and populist parties. The consistent finding is that a large majority – 70% to 80% of Australians – do not support such policies.

But concerns remain over the impact of immigration
While public opinion is generally positive with regard to immigration today, many are concerned about the impact of rising immigrant numbers on their daily lives.
Seventy percent of respondents said they were concerned about “overcrowding”, 60% by the impact of immigration on housing prices and 58% by the impact on the environment.
A new question in 2019 asked for responses to the proposition that “too many immigrants are not adopting Australian values”. Nearly two-thirds of respondents (67%) agreed with the statement.

Policy towards asylum seekers
In 2018 and 2019, a new question asked respondents “are you personally concerned that Australia is too harsh in its treatment of asylum seekers and refugees?”
Opinion was found to be almost evenly divided. In 2019, 49% said they were “a great deal” or “somewhat” concerned, 50% “only slightly” or “not at all” concerned.
Here, too, there were major variances in viewpoints depending on demographics.
For instance, 87% of Greens voters and 61% of Labor voters were “a great deal” or “somewhat” concerned, compared to just 30% of Coalition voters and 16% of One Nation.
A similar split could also be seen with age, with 70% of those aged 18-24 “a great deal” or “somewhat” concerned, compared to just 39% of those aged 55-64. And with location: 55% of Victoria residents were “a great deal” or “somewhat” concerned, compared to 37% of those in Western Australia.

Social cohesion still relatively stable
On the much broader question of social cohesion, our survey continues to find a large measure of stability in Australia.
One indication is provided by the Scanlon Monash Index (SMI), which aggregates responses to 18 questions and measures attitudes in five areas of social cohesion: belonging, worth, social justice, political participation and acceptance of diversity.
Over the course of our 12 national surveys, the SMI registered the highest level of volatility during 2009-2013, the period of the Rudd and Gillard governments, when it declined by more than 10%. It has been largely stable since 2014.
On the individual factors that comprise the SMI, however, there have been some significant changes. When it comes to sense of belonging, for instance, just 63% said they felt this to a “great extent” in 2019, compared to 77% in 2007.
And on the acceptance of diversity, 19% of respondents said they had experienced discrimination on the basis of race, ethnic origin or religion, which was significantly higher than the 9%-10% from 2007 to 2009.
