Climate Change Health Risks Will Hit The Poor Hardest – So What Can Be Done?

Discussions about climate change and the effects it will have on public health and the global burden of disease have been long in the making. These consequences are now starting to come to fore.
Several examples have recently played out. For example, in Russia, an anthrax outbreak in the remote region of Siberia meant that nomadic communities and thousands of reindeer were affected. The outbreak was due to the bodies of infected people buried in 1941 defrosting and releasing anthrax spores into the water system as the permafrost defrosts with global warming.
Closer to home, prisoners are starving in Malawian jails and suffering from acute severe malnutrition as a result of food shortages due to erratic climate conditions from both droughts and floods. Malawi has since declared a state of national disaster.
These unanticipated public health consequences of unsustainable development reminds the world that the issues are not in the distant future, but instead face us now.
Climate change exerts its influence on public health through three main mechanisms.
First, the effects of extreme weather events such as heat, storms, floods or fire that directly cause loss of life or illness.
Second, there are indirect effects of climate change on natural systems. This leads to, for example, changes in disease vectors such as mosquitoes that spread malaria, availability of fresh water, crop survival, or the concentration of pollen in the air.
Third, the effects on economic and social systems as people migrate or conflict over scarce resources.
These effects can be moderated by the presence of early warning systems and effective disaster and emergency medical services.
More affluent communities with more resources will be better able to adapt and withstand these effects. Having strong primary healthcare systems will also increase the resilience of communities.
But in sub-Saharan Africa many communities do not have these protective mechanisms in place, and will be particularly vulnerable to the impact of climate change.

Disease and environmental health
The World Health Organisation has recently published a new report on the burden of disease due to modifiable environmental risks. The report estimates that 23% of all deaths globally can be attributed to environmental risks. This percentage rises to 26% in children.
These environmental risks include:
  • air, water and soil pollution;
  • ultraviolet radiation;
  • the built environment;
  • the occupational environment;
  • agricultural methods; and
  • climate and ecosystem changes.
Children, the elderly, and those living in low- and middle-income countries are most at risk.
The diseases that make the greatest environmentally attributable contribution to the global burden of disease are stroke, ischaemic heart disease, diarrhoea, lower respiratory tract infection, cancers and chronic obstructive pulmonary disease. And over the last ten years the contribution of non-communicable diseases has significantly increased.
An example in South Africa is from Mpumalanga’s Highveld, which has 12 coal fired power stations. The collective air pollution from these power stations has been reported as being responsible for just over half of the deaths from respiratory disease and cardiovascular disease in the area.


Living differently
Sustainable development has been defined as:
… development that meets the needs of the present without compromising the ability of future generations to meet their own needs.
The United Nations’ Sustainable Development Goals recognise that improving the wellbeing and health of people requires an approach that protects the planet from degradation. This is required because there are ecological limits to development that is based on ever-increasing consumption.
But the climate crisis is just one of the manifestations of the world’s collective inability to live sustainably.
There is also a loss of ecosystems and the biodiversity. This compromises the natural services they render to humanity: food, fresh water, clean air, building materials and even new medicines.
Economic inequality is increasing. It is reported that 62 people now own as much wealth as 50% of the planet’s population.
At the same time, we have seen unprecedented population growth and increasing urbanisation that is characterised by the growth of slums or informal settlements.

The 21st-century challenge
Humanity’s biggest challenge in the 21st century may be its ability to find a way of living sustainably and to tackle the crises of both planetary and public health. This will require action on a global scale by world leaders and by a change in collective consciousness.
There are some encouraging signs. Brazil has joined China and the US in ratifying the Paris agreement on tackling climate change. China and the US are responsible for 38% of global emissions.
World religious leaders have also joined forces to promote a change of consciousness as part of a “season of creation”.
It can be summed up in the video message from Pope Francis, who says the relationship between poverty and the fragility of the planet requires another way of managing the economy and measuring progress, conceiving a new way of life.

Was That Climate Change? Scientists Are Getting Faster At Linking Extreme Weather To Warming

The Guardian - 

Attribution studies are letting researchers respond quickly to questions about human influence – before the news cycle turns elsewhere

Is it still true to say you can’t point to any single extreme weather event and claim you can’t link it to human-caused climate change?
Plenty of people seem to think this is still the case. But a rapidly evolving field of climate science suggests that it’s not.
Take Australia’s prime minister, Malcolm Turnbull, for example, who was touring Tasmania after the devastating flooding there in June.
Turnbull pointed out that “larger and more frequent storms” were predicted by climate scientists, but then followed up with that stock standard caveat:
But you cannot attribute any particular storm to global warming, so let’s be quite clear about that. The same scientists would agree with that point.
 But in fact, climate scientists are finding ways to examine the influence of increasing levels of greenhouse gases in the atmosphere on extreme events.
This is a field of science called attribution research. Dr Andrew King, at the University of Melbourne, has been involved with several attribution studies.
So is it time to throw out that old stock response that you can’t blame climate change for any single event? He says:
I would reframe the question – has climate change altered the likelihood of an event happening, like a flood in Louisiana or a heatwave in Melbourne? We can usually say with those types of events that climate change has increased the likelihood of an event happening.
When extreme weather events do strike, questions about human influences are coming up more and more. Some scientists want to be able to respond quickly with more relevant answers, before the news cycle turns elsewhere.
For example, King joined colleagues to look at the record warm sea temperatures that caused the mass bleaching of corals on the Great Barrier Reef last summer. The results were out in April while the reef’s plight was still making headlines.
“We found that the warm sea temperatures were made at least 175 times more likely because of climate change,” King says.
To carry out the research, King looked at two sets of climate models. One was set up to reproduce the levels of greenhouse gases in the atmosphere that we have now and the other had those human influences removed.
In short, the models showed the kind of conditions that eventually killed about a quarter of the corals on the reef are now expected to come around once every four years. But in a world without the extra greenhouse gases, you might expect to see those ocean temperatures once every 1,000 years, if at all.
The reef research is about to be submitted to a journal and so the results could change. But King says the methods being used had been peer-reviewed.
King also looked at the heatwave that had world leaders sweating during the November 2014 G20 summit in Brisbane. Getting a 38C day in November was “at least 44% more likely” thanks to climate change, his study found.
From torrential downpours to record ocean temperatures, heatwaves and the monotonous breaking of monthly and yearly global temperature records, more and more studies are finding a distinct human fingerprint on events.
There have been a bunch of attribution studies looking at heat records in Australia. A study of its consecutive run of record warm springs in 2013 and 2014 found it would have been almost impossible without all that extra carbon dioxide in the atmosphere.
Another study found that without the added greenhouse gases, Australia’s record hot 2013 would only have come along once every 12,000 years. But now, thanks chiefly to the burning of fossil fuels since the industrial revolution, we might expect a record breaker every six years.
Dr Sophie Lewis, at Australian National University, was involved in both those studies. She says climate attribution is a “fast-evolving field” thanks to quicker computers, better collaborations and established methods.
But like King she’s not a fan of simply asking if climate change “caused” something, or was “to blame” for particular events. She says:
A better question is to ask if climate change has influenced a particular event. That’s an important distinction.
An example she gave is 2015 – the planet’s warmest year on record that coincided with an El Niño climate system.
El Niños are natural events that tends to deliver hotter temperatures, but they are happening over the top of human-induced warming that pushes temperatures to record-breaking levels. Lewis says:
We know that both natural and human-caused climate change have impacts on events and we don’t want to lose that complexity. People do understand that the environment and the climate system are complicated.
Speed counts
Getting results out faster gives the media, the public and policymakers more informed answers soon after events hit.
In early August, for example, Louisiana was struck by torrential rains that caused severe flooding – killing 13 people and damaging about 60,000 homes. Less than a month later, a team of scientists concluded that human-caused climate change had probably doubled the chances of Louisiana being hit by downpours like that.
The lead author of that study, Dr Karin van der Wiel, of Princeton University and the US government’s National Oceanic and Atmospheric Administration, told me:
Extreme events have always happened and this could have happened a hundred years ago. But it would have been much more rare.
Van der Wiel says researchers managed to carry out the analysis quickly because the data from the climate models was readily available and they had good had rainfall data for the area.
The Louisiana study has been submitted to a journal where the peer-review process happens out in the open so, again, the conclusions could change.
Now, some scientists are uneasy about research being publicised before it has been through peer review, for obvious reasons. What if, for example, there’s a mistake in the analysis that completely changes the conclusions?
Both Van Der Wiel and King say they can have a degree of confidence in their results because the methods have already been tested. I’ll leave you with King’s thoughts on this.
As far as I see it, one purpose of event attribution is to communicate to the public and policy makers that climate change is altering how extreme events are occurring – both their frequency and how bad they are.
That’s why we’re moving towards doing this work more quickly. If we can better inform the debate, then that provides some useful information that’s grounded in science, when often there has been just speculation.

Climate Change 'Significant And Direct' Threat To U.S. Military: Reports

Reuters - Idrees Ali

The effects of climate change endanger U.S. military operations and could increase the danger of international conflict, according to three new documents endorsed by retired top U.S. military officers and former national security officials.
"There are few easy answers, but one thing is clear: the current trajectory of climatic change presents a strategically-significant risk to U.S. national security, and inaction is not a viable option," said a statement published on Wednesday by the Center for Climate and Security, a Washington-based think tank.
It was signed by more than a dozen former senior military and national security officials, including retired General Anthony Zinni, former commander of the U.S. Central Command, and retired Admiral Samuel Locklear, head of the Pacific Command until last year.
They called on the next U.S. president to create a cabinet level position to deal with climate change and its impact on national security.
A separate report by a panel of retired military officials, also published on Wednesday by the Center for Climate and Security, said more frequent extreme weather is a threat to U.S. coastal military installations.
"The complex relationship between sea level rise, storm surge and global readiness and responsiveness must be explored down to the operational level, across the Services and Joint forces, and up to a strategic level as well," the report said.
Earlier this year, another report said faster sea level rises in the second half of this century could make tidal flooding a daily occurrence for some installations.
Francesco Femia, co-founder and president of the Center for Climate and Security, said the reports show bipartisan national security and military officials think the existing U.S. response to climate change "is not commensurate to the threat".
The fact that a large and bipartisan number of former officials signed the reports could increase pressure on future U.S. administrations to place greater emphasis and dedicate more resources to combat climate change.
Addressing climate change has not been a top priority in a 2016 campaign dominated by the U.S. economy, trade and foreign policy.
Republican presidential candidate Donald Trump has said that global warming is a concept "created by the and for the Chinese" to hurt U.S. business.
Democrat Hillary Clinton, meanwhile, has advocated shifting the country to 50 percent clean energy by 2030 and promised heavy regulation of fracking.

Turnbull Government's Dysfunctional Politics: Foolish And Deadly For Climate

Independent Australia - Peter Boyer

The latest Climate Change Authority report highlights the pressing challenge of global warming. A strong leader would recognise this and bring all forces to bear on it — Turnbull's inaction, is beyond foolish, writes Peter Boyer.
(Image via worldwarming.info)
 THE FINAL REPORT of the Climate Change Authority's (CCA) two-year review of national climate policy ('Towards a climate policy toolkit: Special review on Australia's climate goals and policies') tries to retrieve something of value out of a political mess.
But the report is compromised from the start by the implacably opposed forces it wants to reconcile: a scientific establishment increasingly anxious about climate change and a political establishment determined to treat it as a second-order issue.
The CCA under former Reserve Bank governor Bernie Fraser did what its legislation demanded: give evidence-based advice independent of government —  but it's had to endure a hostile Coalition Government determined to eradicate all trace of Julia Gillard's carbon price scheme.
After a defiant Senate blocked its bill to abolish the CCA, Tony Abbott's Government sought to marginalise it by keeping it at arm's length and ignoring its advice.
The Coalition got the scalp it wanted last year with the resignation of Fraser, who found he couldn't do the bidding of the government while abiding by the CCA's charter.
The new-look board under ecologist, company director and administrator Wendy Craik has kept a distance between itself and government, noting that Australia's emissions will have to improve markedly in the near future. But it's clearly more politically sensitive than its predecessor.
IMAGE link to story
 While the "old" CCA found that Australia should set its 2030 reduction target somewhere between 45 and 65 per cent below 2005 levels – way above the Coalition's 26-28 per cent – Craik's board has avoided making any recommendation on targets.
Instead it proposes a "policy toolkit" building on current policies, with new measures aimed, Craik says, at
' ... a long term durable solution to Australia's climate challenge.' (p88)
This toolkit, she said, would 'take account of Australia's climate policy history', be suited to the needs of individual sectors, and be capable of being
' ... scaled up in the future to meet the emission reduction challenges in the Paris Agreement.' (p9)
That sounds a lot like carbon pricing.
Aware of Coalition paranoia about anything that looks like a tax, the CCA report proposes an 'emissions intensity scheme', using a market mechanism to control emissions from electricity generation, along with an 'enhanced safeguard mechanism' (p66) to control industrial and resource emissions.
Wendy Craik and her board are stuck between a rock – a cabal of conservative politicians zealously blocking any effective climate policy – and a hard place, what Australia has to do to meet its international commitments. They deserve some sympathy.
But only some. As two disaffected CCA members pointed out last week, the CCA's charter clearly dictates that it must focus on the implications of those commitments.
IMAGE link to story
 Atmospheric scientist David Karoly and economist Clive Hamilton argue that the CCA report fails to address Australia's 2013-50 carbon budget — the total amount that the CCA has previously said we can release if we're to contribute our fair share to holding warming below 2C.
Karoly and Hamilton point out that if we stick to the Turnbull Government's current target, by 2030 we'll have used up over 90 per cent of that budget of 10.1 billion tonnes. The trajectory of emissions would then have to drop precipitously to reach net zero within five years — an impossible task.
If 2C is looking impossible for us, where does that leave Paris's more ambitious "aspirational" target? Swedish research published last week calculates that Australia has just six more years at current emission rates before it has entirely used up its budget to hold warming below 1.5C.
When we first learned of global warming a quarter-century ago, crunch time was decades away and postponing strong action could be presented as a plausible option. Now, with time available counted not in decades but a handful of years, it's beyond foolish.
A confident leader with competent deputies in a fully functional political system will acknowledge an unprecedented and pressing challenge and bring all forces to bear on it. Lesser ones will maintain the party divide, divert attention and pretend they have control. Sounds sadly familiar.
People are optimistic by nature – we have to be or we wouldn't get up in the morning – and I'm painfully aware that repeated warnings come at the cost of diminished impact. We all have to get on with our lives. But like Karoly and Hamilton, I don't know what else to do.

“I Climbed Mt Everest And I’m Scared”

Internews - Willie Shubert

A series of stories funded by Internews' Earth Journalism Network shows that climate change is increasing the chances of melting glaciers, landslides and deadly floods in Nepal

Apa Sherpa — who has climbed Everest a record 21 times — is not afraid of heights or blizzards.
"The most worrying issue is that the mountains are holding less and less snow and I can feel it when I climb Mount Everest. It's not a normal phenomenon," he says.

These mountains are the source of water for millions of people living downstream, who depend on them for their lives and livelihoods. Apa Sherpa wants to galvanize the global community to save them. In 2012 he trekked with a team about 1,600 kilometers through the mountains of Nepal for about three months, to show the world the impacts of climate change on the ground.
Apa Sherpa was interviewed recently by Ramesh Bhushal, Nepal editor for thethirdpole.net, a reporting initiative of Internews' Earth Journalism Network (EJN). Bhushal and photographer Nabin Baral travelled along the tributaries of the Koshi River from near Tibet to the Indian border to report on the challenges faced by people living in the region. The Koshi River drains a large part of east-central Himalayas and eventually flows to the Bay of Bengal.

The impacts of climate change along the Koshi River
As glaciers melt due to rising temperatures, the region is experiencing more floods and landslides leading to loss of life, homes and farm land.
Conversely, villages in the south-eastern parts of Nepal are suffering a severe water crisis. Trapped between the lofty mountains and roaring rivers, most of the villages in this part of the Koshi basin have very limited water available for drinking or for irrigation.

"A couple of decades ago we used to have winter paddy cultivation because there was adequate water in April. Now we don't have water to grow maize," Ramesh was told by Bhakta Bahadur Shrestha from Bhimeshwor village in Sindhuli district. Taps in the village were dry, fields were cracked and maize plants were desperately waiting for water.
Because of the water shortages, many families have had to migrate out of the area and those that remain rely on small springs that are often far from where they live. The poverty caused by the lack of water means that some children earn money hauling water instead of attending school.

The government has focused its resources on developing dams and hydropower, which they believe they can sell, instead of addressing water conservation for drinking and agriculture.

Impact of Timely Reporting
In a follow-up report on the series — Timely Reporting Matters: Surfacing Impacts of Data Journalism in the Himalayas — Ramesh documented the impacts that his series had on government officials and the community.
For example, the first story in the series pointed out the possibilities of floods in a region around the Nepal-Tibet border and that an early warning system that had been installed was not maintained and was in poor condition. A flood did occur and the Department of Hydrology and Meteorology fixed the problems very quickly.
"I was following your story, as you pointed out, the early warning system wasn't functioning during that time due to some technical problem," Binod Parajuli, a hydrologist at the department, told Ramesh. "It's working now and we are regularly sending warnings."
"Often stories are reported by the mainstream media only after the disasters," said Nepal's former environment minister Ganesh Shah in the follow-up story, applauding the Koshi series. "…but I think media has a role to bring issues beforehand so that timely decisions could be made by the policymakers."
Shah shared every story in the series through his Facebook page.
Because the headwaters of the river basin are across the Chinese border in Tibet, it was difficult for Nepal to get information about what was going on upstream with regard to glaciers and landslides that may cause flooding. The series emphasized the need for better cooperation between governments to ease the lives of the people living in the river basin. According to a newspaper report, after the series was published, experts in Nepal were able to obtain information confirming that a flood had been caused by water pushing aside a landslide that had blocked the river between Khasa and Nyalum in Tibet.
Journalists in the region also suffer from the lack of information and data sharing. The Koshi basin series provided a lot of data that helped other reporters to understand issues in detail. Ramesh says that Abdullah Miya, senior reporter at Kantipur Daily  — Nepal's largest selling vernacular newspaper — sought his help as he struggled to report on a flood. Ramesh provided him with contacts and a recent scientific paper.
"It was extremely helpful as it is very tough to get information on the Tibet side and reporting this kind of news involves trans-boundary information," Miya said later.
Two reports supported through this series — Is the mighty Ganga drying up? and Ticking time bombs in Uttarakhand — appeared in one of India's largest newspapers, The Hindu. Although it is impossible to draw a direct causal link, after they appeared, the Union Ministry of Water Resources filed an affidavit to the Indian Supreme Court, opposing the building of any more dams in Uttarakhand. This was the first time any central ministry in India had officially taken such a step.

Turnbull Marks 1st Anniversary With Act Of Clean Energy Vandalism

Renew Economy - 

Today is the anniversary of Malcolm Turnbull’s overthrow of Tony Abbott as leader of the Liberal Party, and his ascension as prime minister of Australia. To punctuate 12 months of false expectations, the occasion has been marked with another act of vandalism against Australia’s climate and clean energy policies.
It had been hoped that Turnbull would represent a turnaround in the debate about Australia’s role in the global efforts to control global warming, and whether Australia would be moved to seize its huge opportunity to become a renewable energy powerhouse and a leader in the inevitable clean energy transition.
But rather than taking us to the promised land – “I will not lead a party that does not take climate change as seriously as I do” – things have only got worse. Turnbull has persisted with Abbott’s deluded and deceitful Direct Action policy, and has sought to neuter two important institutions – the Climate Change Authority and the Australian Renewable Energy Agency – that had managed to escape the wrath of Abbott’s “climate change is crap” demagoguery.
The CCA – which survived Abbott courtesy of a bizarre deal with Clive Palmer and Al Gore that led to the death of the carbon price – has, since Turnbull’s coronation, been stacked with ex-Coalition MPs and sympathisers and the original architects of Direct Action, who now praise a policy that was ridiculed by the once fiercely independent authority, and described as a “con” and a “fig leaf” by Turnbull himself.
ARENA, which also managed to dodge Abbott’s toe-cutters, has instead been knee-capped by the Turnbull administration, stripped of $500 million of funding to slow down its ability to provide new competitors to the incumbent fossil fuel industry.
Coalition at work: Announcing cuts to the Australian Renewable Energy Agency (above – tweeted by Mathias Cormann) and celebrating the repeal of the carbon price (below).

Turnbull’s facade was removed from the day he admitted he had agreed, at the behest of the party’s Far Right, to extend Abbott’s climate policies, and then told the world in Paris that coal is good for humanity. Labor’s veneer as self-appointed climate champions has also been severely dented by the cynicism of its factional leaders.
The story around ARENA – and Labor’s attempts to blame the content of a few NGO press releases – highlights that point and the toxic nature of climate change and clean policies in this country.
Let’s go back to March 23 and Turnbull’s announcement of his “innovation agenda” and his announcement of a Clean Energy Innovation Fund, which would appropriate $1 billion of funding already allocated to the Clean Energy Finance Corp, and drip it out over 10 years.
As RenewEconomy pointed out at the time, this was nothing more than a sleight of hand, rebadging funding to conform with Turnbull’s new innovation sloganeering, while proposing to strip ARENA of all its remaining $1.3 billion in funds, a result that would have sent hundreds of research projects, thousands of jobs and billion dollars of projects overseas, and slowed down Australia’s uptake of critical new technologies and energy business models. It would have effectively stopped innovation in it tracks.
Most NGOs didn’t seem to notice and were effusive in their support of Turnbull’s rhetoric. “Finally,” they swooned. RenewEconomy asked if they had actually read the whole press release. Some clearly hadn’t, or had not absorbed its implications, and hurried out amendments. But the damage was done.
The way Labor climate change spokesman Mark Butler puts it, the NGOs’ embrace of the Turnbull package put him in a difficult decision just as Labor was setting out is budget numbers to take to the election. How, he told RenewEconomy, could he defend the ARENA budget when all the environmental NGOs supported the move.
By urging Labor to stand up for its principals and defend the remnants of its fine Clean Energy Future package would be one suggestion.
But whether it was the cause or a pretext, Labor’s numbers people wouldn’t have a bar of it, and the party committed to stripping ARENA of $1 billion, an election policy the Coalition was only too happy to seize upon when it was returned to power.
As the Greens and everyone else point out, Labor could have saved ARENA’s entire budget. But it chose not to.
Meanwhile, Australia faces another two years of a Turnbull government dominated by its hard-right faction. How deeply the conservatives anti-renewables, do-little-or-nothing-on-climate change philosophy seeps through the Coalition ranks is made clear by Coalition positions in state elections, and the enthusiasm of Cormann and Hunt to flag cuts to the CEIF to make up for the compromise it made with Labor on ARENA. They had to row back on those comments, but the threat is clear.
And that is the problem with the toxic nature of Australia’s climate and clean energy policies. Many talk of a spirit of bi-partisanship, but so far all this has achieved is a weakening of an already inadequate policy suite – the renewable energy target has been slashed, the ARENA budget has been sliced, and the same compromise is likely to happen with emission reduction targets and mechanisms.
Bipartisanship needs to be more than reaching for the lowest common dominator, with Labor filling in cracks as the Coalition takes a wrecking ball to climate policies.
Turnbull is not the messiah. He’s just a naughty boy beholden to a conservative rump he dare not cross. And as long as that is the case, the best Australia can hope for is compromise and complacency, when leadership and vision is what is so desperately needed.

August Ties With July As Hottest Month On Record

The Guardian - Andrea Thompson

August continued the remarkable streak of record hot months in 2016, equalling July as the hottest month on record

 In what has become a common refrain this year, last month ranked as the hottest August on record, according to NASA data released Monday. Not only that, but the month tied July as the hottest month the world has seen in the last 136 years.
August came in at 1.76˚F (0.98˚C) above the average from 1951-1980, 0.16C above August 2014, the previous record holder. The record keeps 2016 on track to be the hottest year in the books by a fair margin.
That August continued the streak of record hot months this year and tied July as the hottest month was somewhat unexpected. The seasonal temperature cycle generally reaches a peak in July, as it did this year. But August was so anomalously warm — more so even than July — that it tied that month's overall temperature.
It was also thought that July would likely be the last record hot month of the year, given the dissipation of El Niño.
In NASA's dataset, August marks the 11th record-setting month in a row. That streak goes back 15 months through July in data from the National Oceanic and Atmospheric Administration. Each agency handles the global temperature data slightly differently and uses a different period of comparison, leading to slight differences in the monthly and yearly temperature numbers. Overall, though, both datasets show clear agreement in the overall warming trend.
That trend is what Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, and other climate scientists emphasize. It is that excess heat that has accumulated over decades thanks to rising levels of greenhouse gases that accounts for the bulk of this year's record warmth, with El Niño providing only a small boost.
"Monthly rankings, which vary by only a few hundredths of a degree, are inherently fragile," Schmidt said in a statement. "We stress that the long-term trends are the most important for understanding the ongoing changes that are affecting our planet."

International negotiators hope to curtail that long-term trend by limiting warming to less than 2˚C (3.6˚F) over pre-industrial levels by the end of the century. There have even been discussions to aim for an even more stringent target of 1.5˚C.
To show how close the world already is to surpassing that goal, Climate Central has been averaging the NASA and NOAA temperature data each month and comparing that number to the average from 1881-1910, closer to preindustrial times.
Through July, the global temperature for the year was 1.31˚C (2.36˚F) above the average from that period. A new average will be calculated through August when NOAA releases its temperature data on Sept. 20.
Whether September will continue the record streak is uncertain, but regardless of where it falls, there is already a greater than 99 percent chance that 2016 will take the title of hottest year, Schmidt has said.
