“It’s the same idea as an insurance company raising your property insurance rates because you engage in risky behavior, like drunk driving. But in this case, it’s the fossil fuel sector that’s engaging in risky behavior by contributing to climate change.”

The levels of the three most important heat-trapping gases in the atmosphere reached new record highs again last year, US scientists have confirmed, underlining the escalating challenge posed by the climate crisis. The global concentration of carbon dioxide, the most important and prevalent of the greenhouse gases emitted by human activity, rose to an average of 419 parts per million in the atmosphere in 2023 while methane, a powerful if shorter-lasting greenhouse gas, rose to an average of 1922 parts per billion. Levels of nitrous oxide, the third most significant human-caused warming emission, climbed slightly to 336 parts per billion. The increases do not quite match the record jumps seen in recent years, according to the National Oceanic and Atmospheric Administration (Noaa), but still represent a major change in the composition of the atmosphere even from just a decade ago. Through the burning of fossil fuels, animal agriculture and deforestation, the world’s CO2 levels are now more than 50% higher than they were before the era of mass industrialization. Methane, which comes from sources including oil and gas drilling and livestock, has surged even more dramatically in recent years, Noaa said, and now has atmospheric concentrations 160% larger than in pre-industrial times. Noaa said the onward march of greenhouse gas levels was due to the continued use of fossil fuels, as well as the impact of wildfires, which spew carbon-laden smoke into the air. Nitrous oxide, meanwhile, has risen due to the widespread use of nitrogen fertilizer and the intensification of agriculture.

An Ontario judge harshly criticized the province's climate plan Tuesday, saying it "falls severely short" of what the science on climate change requires, even as she dismissed a landmark lawsuit brought by a group of young people who say the government's actions threaten their future. Superior court judge Marie-Andrée Vermette agreed with the youth applicants on several key points, including that young and Indigenous people are disproportionately impacted by climate change and that the province is risking the lives of Ontarians by not going further on its climate plan. "By not taking steps to reduce GHG (greenhouse gases) in the province further, Ontario is contributing to an increase in the risk of death and in the risks faced by the Applicants and others," Vermette wrote in the decision.

Hot air: five climate myths pushed by the US beef industry

“While fossil fuel consumption has done the most to put us on our dangerous path to climate catastrophe, a widely cited 2020 study in the journal Science argued that we can no longer avoid the worst of the climate crisis by cutting fossil fuels alone. Staying below the average global temperature rise of 2C – a threshold that scientists say will lead to systems collapse, mass extinctions, fatal heat waves, drought and famine, water shortages and flooded cities – will require ‘rapid and ambitious’ changes to food systems.

“The single most impactful food-related change we can make, according to their findings, is not increasing yields, ramping up agricultural efficiency or cutting food waste, though those approaches all would help. It’s adopting a plant-rich diet.

“While building out energy infrastructure can take years, changing our diet is something we can work toward today.”

Eunice Newton Foote was born on July 17, 1819. An American scientist, inventor, and women's rights campaigner, she was the first scientist known to have examined the warming effect of sunlight on different gases and to have suggested that an increase in the proportion of carbon dioxide in the atmosphere would change its temperature and have an effect on climate. A 1856 paper of hers was the first known publication in physics by a woman. She went on to patent several inventions. Foote died in 1888 and for almost a hundred years her contributions were lost, before being rediscovered by women academics in the twentieth century.

Balancing Act: Navigating the Cooling Woes and Warming Tales of Climate Science

Dive into the delicate balance of Earth's climate: Where aerosols cool and greenhouse gases warm. A journey through science, policy, and the quest for harmony. #ClimateBalance

In our relentless quest for a cleaner atmosphere, amendments to the Clean Air Act were hailed as monumental strides toward sustainability. Yet, within this narrative of progress, an unintended plot twist emerged—one that would subtly realign the course of our environmental journey. The well-intentioned reductions in air pollutants, while cleansing our skies of harmful substances, inadvertently…

Surprise! That bird is NOT free.

You can post whatever you like on Twitter these days as long as it does not reveal anything Tsar Elon doesn’t want the masses to know.

Twitter on Wednesday permanently suspended an account that tracked the location of Elon Musk’s private jet, despite the social media company’s owner vowing last month he would leave the account up as part of his “commitment to free speech.”  

The @ElonJet account, which had amassed more than 500,000 followers, was removed as the company posted a new set of edicts that appeared to be designed specifically to justify the removal of the jet-tracking account. The move comes after Musk has reinstated previous Twitter rule-breakers and stopped enforcing the platform’s policies prohibiting Covid-19 misinformation. 

You can post hate speech, kiss up to Ron “Don’t Say Gay” DeSantis, and spread vaccine disinformation on Twitter – but heaven forbid that you should be able to tell the world how Elon Musk is unnecessarily buzzing around the planet in his private jet and adding more greenhouse gases to the atmosphere.

This is typical hypocrisy by billionaire libertarians. The filthy rich either re-write the rules to favor themselves or exempt themselves from those rules. When they express hostility towards equality, it’s because they think they are better than us.

This has been a bad week for Musk. He was greeted with persistent booing at a Dave Chappelle show and now his car company is tanking.

Brutal December for Tesla stock continues

The past eight years were the eight warmest years on record, and 2022 was the fifth-warmest on record globally, according to the European Union's Copernicus Climate Change Service.

Why It Matters: The ranking, released Tuesday morning, shows the planet continues its long-term warming trend in response to growing amounts of greenhouse gases.

• Each of the past 8 years had global average temperatures more than 1°C above the preindustrial level, as the world nears the 1.5°C guardrail established by the Paris Climate Agreement.

• Studies show that the odds of potentially catastrophic climate impacts increase significantly if warming exceeds 1.5°C compared to preindustrial levels.

Of Note: The third year in a row of La Niña conditions in the tropical Pacific Ocean helped depress global average surface temperatures slightly, keeping 2022 from hitting the top three warmest years.

• There are signs, however, that La Niña may soon wane, and potentially give way to an El Niño event during 2023.

• If this were to happen, it would raise the chances for a new all-time record warm year.

The Big Picture: Global average temperatures in 2022 were 0.3°C (0.54°F) above the 1991-2020 baseline, and the year was the second-warmest on record for Europe, behind 2020.

• Europe had its hottest summer on record, accentuated by all-time record high temperatures set in several countries, including the United Kingdom.

• The UK Met Office has found 2022 was its warmest year on record dating all the way to 1659. It was also its first year with an average temperature above 10°C (50°F). France also had its hottest year.

• Areas that saw their warmest year on record include large parts of western Europe, the Middle East, Central Asia and China, northwestern Africa and the Horn of Africa, among others, Copernicus found.

• Worldwide, extreme heat struck Pakistan and northern India during the spring before devastating flooding rains hit the region in late summer. Central and eastern China saw record hot and dry conditions for an extended period over the summer.

Between The Lines: Studies tied these and other extreme weather and climate events to human-driven climate change.

• Research published in September found that climate change may have increased five-day rainfall amounts in the hardest-hit areas of Pakistan by up to 50%.

• Another climate attribution study found that the U.K. heat wave, which peaked in mid-July, was at least 10 times more likely to occur in today's warmer climate compared to the preindustrial era.

Of Note: There were a fair share of precipitation extremes in 2022 as well, with the floods in Pakistan, extreme drought in the Horn of Africa that is pushing that region into a famine, and a series of record floods in Australia.

What's Next: Annual numbers are expected later this week from NOAA and NASA.
