The greenhouse gas no one is talking about

You may know laughing gas from your visit to the dentist. But did you know that it's actually a climate killer – 300 times as potent as CO₂? Why is no one talking about it? And how can we to stop it?

Wildfire smoke and climate change are locked in a vicious circle: Fires worsen climate change, and climate change worsens fires. Alejandro Lazo of CalMatters has four things you should know.

#ClimateChange:
"First, the #fires in #boreal regions become more intense, and, because of the tremendous heat being generated, #peat, which has stored carbon for thousands of years, can start to burn and contribute massive amounts of carbon to the air.
That carbon will take at least another 1,000 years to go back into the peat.

Second, in boreal regions, fires can thaw #permafrost, beginning a cascade of microbial processes that may also generate #GreenhouseGases"

On the two-way feedback #wildfires vs #ClimateChange:

"For Loretta Mickley [...] the fires present a dual problem:
Not only are they a symptom of climate change — becoming bigger, hotter, and more common in regions where they can affect large population centers — but they also make the crisis worse. By burning vast layers of partially decomposed vegetable matter called #peat, fires like those in #Canada release even more #GreenhouseGases into the #atmosphere"

New #Antarctic extremes 'virtually certain' as world warms

Date: August 8, 2023

Source: University of Exeter

Summary:
Extreme events in #Antarctica such as ocean heatwaves and ice loss will almost certainly become more common and more severe, researchers say.

"'Antarctic change has global implications,' said lead author Professor Martin Siegert, from the University of Exeter. 'Reducing greenhouse gas emissions to net zero is our best hope of preserving Antarctica, and this must matter to every country -- and individual -- on the planet.'"

@farhanasultana wow, superbly written and great links too. Really well done. My favourite quote from your article is this - "For instance, many climate policies and solutions, such as carbon trading, offsetting or net zero, are based on the economic principles that have fueled climate change and socioeconomic inequalities in the first place — without actually reducing greenhouse gas emissions. In other words, these solutions fail to address the root causes of the climate crisis and inadequately tackle structural factors for rising greenhouse gas emissions. Indeed, many exacerbate social and economic inequalities on the ground for marginalized communities. Some have even led to violence and displacement of Indigenous groups.' #BIPOC #ClimateCrisis #Climate #Klima #Klimakrise #Indigenous #Colonialism #ClimateDiary #GHG #GreenhouseGases #Greenhouse #GlobalWarming

German supermarket seeks to charge shoppers 'true' environmental cost

their cheap food, often produced on an industrial scale, has a high environmental price. German agriculture was responsible for 55.5 MILLION METRIC TONS OF GREENHOUSE GAS last year, roughly 7.4% of the country's emissions

Public energy utilities exhibit better environmental performance than privately held companies, analysis of 3 novel datasets show. Policies to consolidate/privatize are unlikely to improve greenhouse gas emissions.

#ExxonKnew about #ClimateChange almost 40 years ago

A new investigation shows the oil company understood the science before it became a public issue and spent millions to promote #misinformation

By Shannon Hall on October 26, 2015

"One thing is certain: in June 1988, when NASA scientist #JamesHansen told a congressional hearing that the planet was already warming, Exxon remained publicly convinced that the science was still controversial. Furthermore, experts agree that Exxon became a leader in campaigns of confusion. By 1989 the company had helped create the #GlobalClimateCoalition (disbanded in 2002) to question the scientific basis for concern about climate change. It also helped to prevent the #USA from signing the international treaty on climate known as the #KyotoProtocol in 1998 to control #GreenhouseGases . Exxon’s tactic not only worked on the U.S. but also stopped other countries, such as #China and #India, from signing the treaty. At that point, 'a lot of things unraveled,' Oreskes says.

"But experts are still piecing together Exxon’s misconception puzzle. Last summer the Union of Concerned Scientists released a complementary investigation to the one by InsideClimate News, known as the Climate Deception Dossiers (pdf). 'We included a memo of a coalition of fossil-fuel companies where they pledge basically to launch a big communications effort to sow doubt,' says union president Kenneth Kimmel. 'There’s even a quote in it that says something like ‘Victory will be achieved when the average person is uncertain about climate science.’ So it’s pretty stark.'

"Since then, Exxon has spent more than $30 million on #ThinkTanks that promote ClimateDenial, according to #Greenpeace. Although experts will never be able to quantify the damage Exxon’s misinformation has caused, 'one thing for certain is we’ve lost a lot of ground,' Kimmell says. Half of the greenhouse gas emissions in our atmosphere were released after 1988. 'I have to think if the fossil-fuel companies had been upfront about this and had been part of the solution instead of the problem, we would have made a lot of progress [today] instead of doubling our greenhouse gas emissions.'"

"The 'gateway to the #underworld,' as some locals in Russia's Sakha Republic also call it, has a scientific name: a mega-slump.

"And while it may attract tourists, the slump's expansion is 'a sign of danger,' said Nikita Tananayev, lead researcher at the Melnikov Permafrost Institute in #Yakutsk."

#UK poised to drop plans to replace home #gas #boilers with #hydrogen alternatives | #HydrogenPower | The Guardian

In my opinion, it was a silly idea to replace natural gas infrastructure with hydrogen burning, primarily because it is not produced in an environmentally friendly way and the current method pumps out lots of #GreenhouseGases and #Pollution, thus negating the supposed benefit of burning it.
