(BBC News) Climate Change: Huge Toll Of Extreme Weather Disasters In 2021

BBC News -  Matt McGrath

In the latest Climate Check, Ben Rich looks back at some of the year's defining weather events

Weather events, linked to a changing climate, brought misery to millions around the world in 2021 according to a new report.

The study, from the charity Christian Aid, identified 10 extreme events that each caused more than $1.5bn of damage.

The biggest financial impacts were from Hurricane Ida which hit the US in August and flooding in Europe in July.

In many poorer regions, floods and storms caused mass displacements of people and severe suffering.

Not every extreme weather event is caused by or linked to climate change, although scientists have become bolder in exploring the connections.

One leading researcher, Dr Friederike Otto, tweeted earlier this year that every heatwave happening in the world now is "made more likely and more intense" by human induced climate change.

In relation to storms and hurricanes, there is growing evidence that climate change is also affecting these events.

In August, the Intergovernmental Panel on Climate Change (IPCC) published the first part of its sixth assessment report.

In relation to hurricanes and tropical cyclones, the authors said they had "high confidence" that the evidence of human influence has strengthened.

"The proportion of intense tropical cyclones, average peak tropical cyclone wind speeds, and peak wind speeds of the most intense tropical cyclones will increase on the global scale with increasing global warming," the study said.

Just a few weeks after that report came out, Hurricane Ida hit the US.

According to Christian Aid it was the most financially destructive weather event of the year.

The slow-moving hurricane saw thousands of residents in Louisiana evacuated out of its path.

That storm brought massive rainfall across a number of states and cities, with New York issuing a flash-flood emergency alert for the first time.

Around 95 people died, with the economic losses estimated at $65bn.

The second most financial costly event was the widespread flooding across Germany, France and other European countries in July.

The speed and intensity of the water overwhelmed defences and 240 people lost their lives. Reported damages were around $43bn.

In the study, the majority of the weather events in the list occurred in developed countries.

That's because it is more feasible to estimate financial losses from insurance claims and these are usually available in richer countries, where people can afford to insure their homes and businesses.

According to insurance company Aon, 2021 is likely to be the fourth time in five years that global natural catastrophes have cost more than $100bn.

The report also documents many other events where the financial impact is harder to ascertain, but where the impact on people is significant.

Flooding in South Sudan displaced over 800,000 people while 200,000 had to move to escape Cyclone Tauktae which hit India, Sri Lanka and the Maldives in May.

"That's a huge human impact," said report author Dr Kat Kramer from Christian Aid.

"Obviously, losing your home, your livelihoods, and everything, and not having the resources to rebuild that is incredibly tough. Whereas at least if you have insurance, you have some mechanism for building that back."

The report highlights the need for increased efforts on curbing emissions of carbon dioxide to reduce future weather related impacts. It is also calling on global climate diplomats to put their money where their mouth is and help poorer countries that suffer huge economic losses.

In the COP26 global climate talks in Glasgow, this issue of finance for loss and damage caused by climate-related events saw major disagreement between countries. Developing nations wanted cash - the richer ones said we need more talks on the question.

"Although it was good to see the issue of loss and damage become a major issue at COP26, it was bitterly disappointing to leave without a fund set up to actually help people who are suffering permanent losses from climate change,' said Nushrat Chowdhury, Christian Aid's climate justice adviser in Bangladesh.

"Bringing that fund to life needs to be a global priority in 2022."

(Scientific American) The Five Biggest Climate Stories of 2021

Climate-fueled disasters raged around the globe while international action fell short of ambitions

It feels like we are lurching from one disaster to another: as wildfires blaze across part of the country, a hurricane swamps a different area—and all this happens as a pandemic continues to rage. Costs are steadily mounting, making action to stem the release of greenhouse gases ever more urgent. Hopes on that front remained unfulfilled in 2021, but the year did hold some bright spots—including Washington, D.C.’s U-turn on climate policy after President Joe Biden took office in January.

Here, we take a look back at some of the biggest climate stories of the year.

Heat, Wildfires and Floods



         Climate change fueled weather extremes of every type around the world this year. Conflagrations raged across Siberia, Greece, India and other areas. California, a major epicenter of wildfire activity in recent years, again saw devastating blazes. The Dixie Fire, the second-largest in the state’s history, burned nearly one million acres. It and the Caldor Fire were the first to burn up and over the crest of the Sierra Nevada mountains, a feat enabled by a landscape altered by climate change.

Wildfire activity across the western U.S. has been driven by extreme heat and drought, both of which were exacerbated by climate change. By early summer a record 93 percent of the West was in drought, leaving forests and grassland dry and primed to ignite. A major heat wave struck the Pacific Northwest and southwestern Canada in June, shattering temperature records. On the worst day of the event, temperatures in normally cool and damp Seattle hit 108 degrees Fahrenheit, while Portland reached a scorching 116 degrees F. It is thought the event—which one analysis found would have been “virtually impossible” without climate change—contributed to the deaths of several hundred people. More than a billion sea creatures also succumbed to the heat.

Months later torrential rains unleashed floods in the same area, displacing thousands of residents. Canadian officials called the downpours that hit British Columbia—where some places measured six inches of rain in a day—a “one-in-500-year” event. Rain-driven floods also swept through river valleys in Germany, Belgium and Denmark, destroying buildings and killing more than 200 people. An analysis found the European floods were up to nine times more likely in a warmer climate.

Another busy U.S. hurricane season—on the heels of the record-breaking one in 2020—also brought flooding to parts of the country. Hurricane Ida slammed into the Louisiana coast as a Category 4 storm in August (on the anniversary of 2005’s Hurricane Katrina), after rapidly intensifying. It caused destruction across the state, particularly in low-income communities. Rain from Ida’s remnants went on to trigger deadly floods in parts of the Northeast, including New York City.

The Science Has Spoken



It is increasingly clear that such events—which destroyed so many homes, lives and livelihoods this year—are already being worsened by global warming, according to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change, released in August. The report incorporates the latest research to give a comprehensive view of the state of climate science for the first time in eight years.

Put together by more than 200 scientists, the report is the most confident one to date on what is driving the changing climate, declaring that “it is unequivocal that human influence has warmed the atmosphere, ocean and land.”

The authors also warn that countries’ current commitments to reduce greenhouse gas emissions will still allow global temperature to rise beyond the two degrees Celsius (3.6 degrees Fahrenheit) above preindustrial levels, the target limit agreed to under the 2015 Paris climate agreement.

Climate Anxiety



That gap between government ambition and effective action is a major factor in an issue that was thrust into the limelight this year: climate anxiety. The condition came to the fore after a landmark 10-country survey of 10,000 people aged 16 to 25 was first published online in September in the Lancet Planetary Health. It found that 60 percent of respondents were “very” or “extremely” worried about climate change and that 45 percent said their associated feelings of sadness, anger and anxiety were impacting their daily life. The term “eco-anxiety,” by which this distress is also known, was even added to the Oxford English Dictionary this year.


U.S. Pivot



This year the U.S.’s position on climate change was completely reversed from what it was in 2020, after Biden was inaugurated in January and began undoing his predecessor’s rollbacks of measures to stem warming. On day one in office that month, the Biden administration filed the paperwork needed to rejoin the Paris climate agreement as of February 19. He has also directed federal agencies to take climate change into account when evaluating infrastructure projects. Other Biden executive orders end federal financing of coal and other carbon-intensive projects abroad and, in an effort to address issues of environmental justice, stipulate that 40 percent of the benefits of federal climate action should go to disadvantaged communities.

On the global stage, Biden held an international summit on Earth Day (April 22), pledging the U.S. would cut its carbon emissions in half by 2030. The president subsequently joined with European Union leaders in promising to cut emissions of methane, a particularly potent greenhouse gas.

The Biden administration also initiated the nitty-gritty work of revamping federal rules and regulations to actually meet those targets, as well as of restaffing involved agencies that were gutted by previous president Donald Trump. The social cost of carbon—which helps account for the damage caused by climate change when evaluating various programs and projects—was raised to $51 a ton, up from as little as $1 a ton during the Trump administration. And just in December, the Environmental Protection Agency released stronger vehicle emissions standards—a key issue, because transportation is the biggest contributor to U.S. greenhouse gas emissions.

But some of the Biden administration’s actions have drawn criticism—notably, continuing to hold leases for oil and gas drilling on federal lands. The president’s aims have also hit roadblocks in Congress, where passing climate-related legislation is crucial because it is less subject to being reversed by subsequent administrations or to being challenged in court. Though Congress passed an infrastructure bill with climate provisions, the more substantial climate provisions in the Build Back Better Act have been stymied after Democratic Senator Joe Manchin of West Virginia withdrew his support for the bill in December. That leaves a major question mark hanging over the president’s climate agenda going into the new year.

All Eyes on Glasgow



More question marks linger after the much anticipated 26th United Nations Climate Change Conference of the Parties (COP26) was finally held in Glasgow, beginning on October 31, after a year’s delay because of the coronavirus pandemic. The purpose of the meeting was for countries to strengthen their emissions reduction pledges under the Paris climate agreement. While many did, the revamped pledges were not as ambitious as environmental activists had hoped—or as climate scientists have said such pledges would need to be in order to keep warming below the two-degree-C (3.6-degree-F) goal. An analysis conducted after the meeting found that current commitments could still result in three degrees C (5.4 degrees F) of warming by 2100.

At the meeting, the U.S. declined to sign on to a commitment with more than 40 other countries to end coal burning, but it did reach an agreement with China to share technology that can help capture and store carbon and to develop methane-reduction policies. (The U.S. and China are the largest contributors of greenhouse gas emissions.) The U.S. also resisted efforts by developing countries, particularly small island nations, to establish funding to compensate them for the damages and irreparable losses already wrought by climate change.

Countries did agree to bring updated emissions reduction pledges to next year’s COP 27 meeting, to be held in Egypt, rather than waiting until 2025—giving some hope that 2022 will see the world come closer to averting climate catastrophe.

(AU SMH) The Themes That Dominated Environmental Action In 2021

Sydney Morning HeraldNick O'Malley | Nick Toscano

This year, environmentally-minded eyes focussed squarely on the climate crisis, with the Glasgow summit driving support for quicker action from unlikely quarters.

For anyone with a passing interest in climate and environment politics and policy, there was simply no escaping the Conference of the Parties in Glasgow this year.

By any analysis the commitments made by the 197 signatories to the Paris Agreement made in Glasgow in November constituted too little action to halt global warming, made way too late.

But, in the weeks since it ended, something like a consensus has emerged that its achievements were significant.

Firstly, it proved that the Paris Accord has held and can function. Secondly, it cemented the more ambitious target of holding warming to 1.5 degrees as the central focus of efforts over 2 degrees, which many nations had sought to entrench in Paris in 2015.

For the first time, a UN document called specifically for coal to be phased down (rather than out, as an earlier draft had put it) and huge commitments were made by many nations to reduce logging and fossil fuel use.

Whether that 1.5 degree target can be achieved is more than in doubt. An analysis by the International Energy Agency found that if every commitment announced at the conference be kept – and that is a huge if – the world remains on track for 1.8 degrees warming.

At the end of the conference, United Nations Secretary-General Antonio Guterres announced the effort to reach 1.5 degrees was still alive, but on life support.

It did not help that within days of the conference ending, Australia, New Zealand, and the EU all signalled they would not increase their targets before next year’s COP27 Climate Summit, as they had been called upon to do in the Glasgow Pact they had just signed.

Australian politics reacts

In the face of a public pressure campaign waged by some of Australia’s most powerful friends, including the UK and the US, Prime Minister Scott Morrison eventually announced a net zero by 2050 target and agreed to attend the COP.

There he confirmed that Australia’s 2030 target would remain 26 to 28 per cent, bolstered by a projection that the actual cut would end up being as high as 35 per cent.

Both targets are well below what scientists say would be a fair contribution to the global effort to hold warming to 1.5 degrees later this century, and disappointed observers here and abroad.

After the conference, Labor announced its own policy which included a target of 43 per cent by 2030, also short of the action scientists believe is necessary.

Indeed, only the Greens policy of reducing emissions by 75 per cent by 2030 is in line with the reductions the Climate Council has cited as necessary.

Despite this, the Labor policy was generally well-received by climate observers.

“Labor’s plan helps bridge the gap between the Morrison Government’s do-nothing approach and state government and business leaders who are forging ahead to create jobs and grow our nation’s prosperity by slashing emissions this decade,” said the Climate Council’s chief executive Amanda McKenzie.

Richie Merzian, director of energy and climate policy with The Australia Institute, said many in the field were simply exhausted by the climate wars that have cruelled climate policy for a generation in Australia, and willing to welcome any real movement by the major parties.

With News Ltd newspapers supporting the government’s net zero plan and the Business Council of Australia backing Labor’s targets, there was reason by year’s end to believe those wars may be ebbing.

The energy revolution

Buoyed by the findings of a landmark 2020 report by the International Energy Agency that solar power had become the cheapest energy created in history, an international movement coalesced around the COP to make this the year that fossil fuels were finally knocked out of the economy – or at least peaked.

Sun Cable is the world’s largest solar farm, delivering power from the Australian outback to the Northern Territory and Singapore.

This was not a fringe movement either. As COP host Boris Johnson was a cheerleader, and since the UK had managed to shrink its coal use from 25 per cent of the nation’s power to under 1.6 per cent, his was a credible voice. The United States climate envoy John Kerry threw his weight into the effort too and enjoyed the backing of the EU.

At the COP, a group of developed nations raised money to help South Africa shut down its dirty coal industry and in the weeks after, the Asian Development Bank laid out a plan to raise capital to buy out and shut down coal power stations in this region.

But even as a group of 40 nations signed a pledge to abandon coal at the COP, a grim set of unforeseen circumstances was causing coal and gas prices to surge to new records – blackouts engulfing China and India.

An oddly windless northern Autumn had reduced the expected amount of wind power available in Europe just as a cold snap lifted heating demand. With the so-called pipeline of new fossil projects already constricted due to the lingering shock of the COVID-19 downturn and the flow of global capital away from new fossil fuel projects, supplies were failing to keep pace with a sharper-than-expected return in demand, causing a crippling shortage of fossil fuels that would have seemed unthinkable just one year earlier.

Few believe though that the surge in demand will be sustained. Indeed, the first energy shock of the green power era could even drive nations to faster embrace renewable and firming technologies to free themselves from capricious global energy markets.

Business gets on board

With the reshaping of global energy markets now looking more like a practical reality rather than an activist fantasy, the world’s major energy companies began to rebuild themselves.

Australia is home to some of the world’s biggest resources companies. And as the push to arrest climate change became markedly more urgent this year, investors continued retreating from companies in the business of drilling up planet-heating fossil fuels, pushing the cost of capital higher and triggering a wave of merger and acquisition activity.

BHP, the nation’s largest mining company, has stepped up plans to better align its portfolio with the global decarbonisation mega-trend, striking a deal to sell its entire petroleum division to Perth-based Woodside, and continuing in its efforts to sell out of thermal coal.

Two of Australia’s top oil and gas producers – Santos and Oil Search – agreed to a $21 billion merger in the hope of gaining greater capacity to self-fund their growth projects as financial challenges intensified.

Meanwhile, the influx of new large-scale renewable energy and rooftop solar panels across Australia’s east-coast electricity grid has led to a major shake-up of the market, causing wholesale power prices to plunge to levels where fossil fuel-based generators have been increasingly struggling to stay viable.

In March, the pressure caused EnergyAustralia to announce it would shut down its giant Yallourn coal plant in Victoria’s Latrobe Valley in 2028, four years earlier than scheduled, while AGL has unveiled plans to embark on a historic demerger to split off its carbon-heavy coal- and gas-fired power stations after sinking to a $2 billion full-year loss.

But it was not just the big emitters that began preparing for a new world. Over the year it became clear that the financial sector was on board with the broader decarbonisation movement, and in this country at least appeared to be more enthusiastic to act than the government itself.

Chief executive of the Carbon Market Institute John Connor says it was clear from conversations with Australian executives this year that climate was no longer a fringe issue, but front and centre in the nation’s boardrooms.

He notes that the price of carbon credits on the Australian market climbed from around $16.50 at the start of the year to almost $50.

This year it became clear that the EU is determined to introduce some form of carbon border tariff, penalising carbon-intensive products from crossing its border. Should the policy succeed it is likely to be replicated, driving a virtuous circle of greening-for-profit in the global supply chain.

It was also the year that hydrogen became a darling of governments pursuing new clean industries and investors seeking to make a clean buck.

In Australia, Andrew Forrest pumped money into projects to build the electrolysers to make hydrogen and renewable energy infrastructure to power them.

Forrest was rewarded with an audience with Joe Biden at COP where he was invited to join the so-called “First Movers Coalition”, a vehicle the US President was backing to help accelerate the expansion of new green industries.

But still the world warmed

With such a focus on climate policy and politics, and with south-eastern Australia enjoying a period of weather brought about by the La Nina weather pattern, it was possible at times to lose sight of the pace of change in our climate, despite the floods and tornadoes that struck the region.

It was not this way in northern Australia, or in other parts of the world.

Researchers Rohan Fisher and Neil Burrows, of Charles Darwin University and the University of Western Australia respectively, found that in October and November alone, extreme weather conditions contributed to 120,000 square kilometres of Australia’s tropical savannah and rangelands burning.

With heating increasing, the world has slipped into what they call a global age of fire, a pyrocene.
