BRUSSELS (AP) — Dressed as endangered fish or tigers or wearing toy polar bears on their heads, demonstrators marched through Brussels on Sunday to push world leaders to take bolder action to fight climate change at the UN climate summit in Glasgow starting this month.

Thousands of people and 80 organisations took part in the protest, aiming for the biggest such event in the European Union's capital since the start of the coronavirus pandemic, which stopped the climate movement’s weekly marches in its tracks.

Cyclists, families with children and white-haired demonstrators filled city streets, chanting slogans demanding climate justice and waving banners in English, French and Dutch. One carried a stuffed polar bear on her head, and others were dressed as animals endangered by human-caused climate change.

“After you’ve seen all the disasters we have seen this summer, it’s really crucial that we move now. Because everybody knows what the problem is," said Xavier De Wannemaeker, a protester with Extinction Rebellion.

Scientists say there's little doubt that fuel emissions are contributing to extreme weather events like the droughts, fires, floods that have hit regions around the world this summer.

Demonstrator Lucien Dewanaga asked, “What do we do when we destroy the planet? We have nothing else. Human beings have to live in this world. And there is only one world.”

Environmentalists worry that the UN's 26th Climate Change Conference of the Parties, known as the COP26, in Glasgow starting October 31 will produce policies that don’t do enough to slash carbon emissions and slow the warming of the planet. Read the whole story here.

Climate change is the most formidable challenge humanity has had to face since World War II and will require similar levels of individual mobilization and collective cooperation.

“We need 8 billion people to make this a personal cause. The world has never seen a challenge like this probably since World War II,” Robert Moritz, chairman of PricewaterhouseCoopers, said Monday at Climate Week NYC.

“And the reality is that we have to mobilize the whole world,” Moritz said.

“Let me square this up for everybody: We are behind,” he said.

“The reality is, when you look at the numbers, when you look at the academic studies, at least our research would say we don’t necessarily need to double the efforts, triple the efforts, we actually have to fivefold the increase of the change we need to do to decarbonize the world that is going on right now,” Moritz said.

To do that will require collaboration and cooperation across industries, sectors, stakeholders and leaders.

“How do we pull together all of the puzzle pieces and start to connect them, sector by sector, section by section, country by country, to do this?” Moritz said. Read the whole story here.

Enough With The Climate Jargon: Scientists Aim For Clearer Messages On Global Warming

Here's a sentence that's basically unintelligible to most people: Humans must mitigate global warming by pursuing an unprecedented transition to a carbon neutral economy.

A recent study found that some of the most common terms in climate science are confusing to the general public. The study tested words that are frequently used in international climate reports, and it concluded that the most confusing terms were "mitigation," "carbon neutral" and "unprecedented transition."

"I think the main message is to avoid jargon," says Wändi Bruine de Bruin, a behavioral scientist at the University of Southern California and the lead author of the study. "That includes words that may seem like everyone should understand them."

For example, participants in the study mixed up the word "mitigation," which commonly refers to efforts that reduce greenhouse gas emissions, with the word "mediation," which is a way to resolve disputes. And even simple terms such as "carbon" can be misleading, the study found. Sometimes, carbon is shorthand for carbon dioxide. Other times, it's used to refer to multiple greenhouse gases.

Climate change will transform cooling effects of volcanic eruptions, study suggests

Researchers have shown that human-caused climate change will have important consequences for how volcanic gases interact with the atmosphere.

The researchers, from the University of Cambridge and the UK Met Office, say that large-magnitude eruptions will have greater effects as the climate continues to warm. However, the cooling effects of small- and medium-sized eruptions could shrink by as much as 75%. Since these smaller eruptions are far more frequent, further research is needed to determine whether the net effect will be additional warming or cooling.

Where and when a volcano erupts is not something that we can control, but as the atmosphere warms due to climate change, the plumes of ash and gas emitted by large, but infrequent, volcanic eruptions will rise ever higher. Climate change will also accelerate the transport of volcanic material—in the form of small, shiny droplets called volcanic sulfate aerosols—from the tropics to higher latitudes.

For large eruptions, the combined effect of these phenomena will cause the haze created by volcanic aerosols to block more sunlight from reaching Earth's surface, ultimately amplifying the temporary cooling caused by volcanic eruptions. The results are reported in the journal Nature Communications.

When Mount Pinatubo in the Philippines erupted in 1991, the effects were felt worldwide. The plume from the eruption—the second largest of the 20th century—reached more than 30 kilometers into the sky, forming a layer of global haze. In 1992, this haze caused global temperatures to drop by as much as 0.5 degrees Celsius. In comparison, human activities have warmed global temperatures by over 1 degree Celsius since 1850. However, the effect of volcanic aerosols only persists for one or two years, while anthropogenic greenhouse gases will affect the climate for centuries. Read the whole story here.

When turning on faucets is a source of stress: Climate change shapes where Americans relocate

4 August 2021

Garrett and Megan Warren, with their son, Reeve, 6, decided to relocate to Portland, Ore., from Los Angeles in 2016 because of drought conditions in California.

Megan Warren, who grew up in Southern California, had lived in Los Angeles for 15 years when she decided she’d had enough.

During periods of drought, when the city tried to conserve water and added plastic balls to the reservoir to reduce evaporation, neighbors in the Miracle Mile didn’t seem to care, she says.

She’d drive down her street and see one of them hosing off his driveway and others using sprinklers on their lawns. She had removed the “brown, dry and crispy grass” and water-dependent landscaping from her lawn and replaced it with succulents and ground cover that could survive in dry conditions.

“Every time I turned on the faucet to wash my dishes, it was really a source of stress for me,” she says. “I just wanted to go to a place where I could take a shower without worrying about water.”

As she explored her options, the Pacific Northwest seemed like a “dreamland."

“There's plentiful water, and everything is green and lush and growing," she says. "And they have four seasons, and it's beautiful."

In 2016, her family picked Portland, Oregon, as their new home because the city had made ecological advances such as composting 67% of its waste, offered great public transportation options and had residents who seemed environmentally conscious.
Warren is among a growing number of Americans who may be starting to factor climate change into decisions about where they live. Read the whole story here.

Scientists predict climate change will cause more intense storms across Europe

As rescue workers race to save people from devastating floods in Germany and Belgium, climate experts are sounding the alarm over predictions that intense, slow-moving storms will increase significantly across Europe by the end of the century.

According to a new study by scientists at Newcastle University in the U.K. and the country’s national weather service, the slow-moving pace of some storms can increase the amount of rainfall that accumulates in one particular region, which then raises the risk of flash floods.

Scientists suggest the cause of this severe weather is linked to climate changeand their findings were recently published in the journal, Geophysical Research Letters.

"This study shows that in addition to the intensification of rainfall with global warming, we can also expect a big increase in slow-moving storms which have the potential for high rainfall accumulations,” Lizzie Kendon, science fellow at the Met Office and professor at Bristol University, said in a statement. “This is very relevant to the recent flooding seen in Germany and Belgium, which highlights the devastating impacts of slow-moving storms.”

She added, "Our finding that slow-moving intense rainstorms could be 14 times more frequent by the end of the century under the high emissions RCP8.5 scenario shows the serious impacts that we may expect across Europe if we do not curb our emissions of greenhouse gases." Read the whole story here.

The Bank of Japan unveiled a plan on Friday to boost funding for fighting climate change, a surprise move underscoring the growing importance of the issue for central banks.

Following is a snapshot of how some of the world's biggest central banks are addressing risks related to climate change and in some cases helping to tackle it, as well as their thinking on how much more they should be doing...

...EUROPEAN CENTRAL BANK - The ECB is already using supervisory powers to force banks to own up to their role in financing polluters, and it will conduct a climate stress test next year. Initial findings show around 90% of banks do not yet follow ECB guidelines in assessing climate risk.

The ECB is also looking at tailoring monetary policy to favour companies working to reduce their carbon footprint or to punish polluters. Options under consideration include skewing asset purchases to favour companies with low emissions or those who make a concerted effort to transform their business.

The bank is considering modifying rules to make it harder for lenders to fund polluting projects. As commercial banks sit on over 2 trillion euros ($2.4 trillion) worth of ECB loans, raising collateral requirements on brown assets could quickly raise funding costs. Read the whole story here.

Climate Change Batters the West Before Summer Even Begins

A heat dome is baking Arizona and Nevada, where temperatures have soared past 115 degrees this week and doctors are warning that people can get third-degree burns from the sizzling asphalt.

At Lake Mead, which supplies water for 25 million people in three southwestern states and Mexico, water levels have plunged to their lowest point since the reservoir was filled in the 1930s. In California, farmers are abandoning their thirstiest crops to save others, and communities are debating whether to ration tap water.

In Texas, electricity grids are under strain as residents crank their air-conditioners, with utilities begging customers to turn off appliances to help avert blackouts. In Arizona, Montana and Utah, wildfires are blazing.

And it’s not even summer yet.

“We’re still a long way out from the peak of the wildfire season and the peak of the dry season,” said Daniel Swain, a climate scientist at the University of California, Los Angeles. “Things are likely to get worse before they get better.”

Global warming, driven by the burning of fossil fuels, has been heating up and drying out the American West for years. Now the region is broiling under a combination of a drought that is the worst in two decades and a record-breaking heat wave.

“The Southwest is getting hammered by climate change harder than almost any other part of the country, apart from perhaps coastal cities,” said Jonathan Overpeck, a climate scientist at the University of Michigan. “And as bad as it might seem today, this is about as good as it’s going to get if we don’t get global warming under control.” Read the whole story here.
