Get ready for #BlackLung

#Trump set to sign #ExecutiveOrders to boost #US #coal

When burned, coal releases more of the main #GreenhouseGas carbon dioxide than any other #FossilFuel. It also emits criteria #pollutants that are blamed for #lung & #heart illnesses. Much of its use has declined on #regulations from #Democrats, including President Joe #Biden.

State of the Global Climate 2024

Key messages:

Key #ClimateChange indicators again reach record levels

Long-term #warming (averaged over decades) remains below 1.5°C

#SeaLevelRise and #OceanWarming #irreversible for hundreds of years

Record #GreenhouseGas concentrations combined with #ElNiño and other factors to drive 2024 record heat

Early warnings and #climate services are vital to protect communities and economies

The clear signs of human-induced climate change reached new heights in 2024, which was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average.

The order by US Dist Judge #Chutkan prevents—for now—the #EPA from ending the $20B #grant program.

Chutkan's order also blocks #Citibank, which holds the money on behalf of the EPA, from transferring the money back to the govt or anyone.

#ClimateUnitedFund & other groups sued #Trump’s EPA, its admin #LeeZeldin & Citibank, saying they had illegally denied the groups access to $14B awarded last year through the #GreenhouseGas Reduction Fund, commonly referred to as a “green bank."

Trump’s #EPA clearly shows it doesn’t understand the assignment
31 separate actions roll back restrictions on #air and #water #pollution.
#LeeZeldin exulted over the plan to rescind EPA’s 16yo determination #greenhousegas is a danger to #publichealth and welfare, known as #endangermentfinding
Zeldin announced EPA would revise a key definition that guides environmental protection under #CleanWaterAct, a change advocates say would threaten water supplies for millions in #US

Another #GOP boondoggle -

#Virginia court freezes order that Virginia’s return to #RGGI (Regional #GreenhouseGas Initiative) while #VAgov Youngkin (R) appeals lower court ruling he acted illegally when he took the state out of the regional carbon-trading program.

Virginians lose out on millions in funding for #energy efficiency & flood preparedness.

E&E News by POLITICO · Court freezes order on Virginia’s RGGI exitThe state will remain out of the regional carbon-trading program, pending appeal of a finding that the state's withdrawal was illegal.

New report finds just 36 #FossilFuel firms account for 50% of global #greenhousegas #emissions .

16 out of the top 20 global emitters of #CO2 are govt operated state entities including corps from China, Iran, Russia & Saudi origin.. #ExxonMobil is slightly behind Iran's state owned oil company in pumping emissions, both each responsible for approx 2% of global total.

The move appears aimed at increasing domestic supply as #Trump threatens #tariffs on #timber imports from #Canada, #Germany, #Brazil & elsewhere. #Environmental groups say increased #logging would decimate American #forests, #pollute #air & #water & devastate #wildlife #habitats.

And because trees absorb & store carbon dioxide, a #GreenhouseGas, cutting them down releases it back into the atmosphere, adding to #GlobalWarming.

Renewable energy: rural areas can be the EU’s green powerhouse.

The European Union aims to cut greenhouse gas emissions by at least 55% in 2030 compared to 1990 levels, and to become the first carbon-neutral economy by 2050.

This ambitious goal requires a radical increase in the production of green energy within a relatively short timeframe. The untapped potential of rural areas in the union offers a way forward.

@mattotcha while getting rid of #methane sounds good, it’s turned into #CO2 which is less potent a #GreenhouseGas but much much longer lived. Maybe just keeping as much in the ground is best or where there are rubbish tips, use it to generate electricity. Have no idea how to deal with the releases in the Arctic/Antarctic which look to be much bigger than all the rubbish tips combined.

#Earth is already shooting through the 1.5°C #globalwarming limit, two major studies show
Both studies also demonstrate that even if stringent #emissions reduction begins now, Earth is still likely to be crossing the 1.5°C threshold.
But humanity’s #greenhousegas emissions have continued to increase. Since the Intergovernmental Panel on #ClimateChange released its first report in 1990, the world’s annual #carbondioxide emissions have risen about 50%.

The ConversationEarth is already shooting through the 1.5°C global warming limit, two major studies showEarth is crossing the 1.5°C limit outlined in the Paris Agreement, beyond which scientists predict catastrophic harm to systems supporting life on our planet.

The rate at which atmospheric CO2 is increasing is now outpacing the pathways set out by the Intergovernmental Panel on Climate Change (IPCC) that limit global warming to 1.5C.

The third working group report of the #IPCC’s sixth assessment report (#AR6), published in 2022, presented a set of seven “illustrative pathways” that highlight how different mitigation choices across major economic sectors translate into future #GreenhouseGas #emissions and global temperatures.

In the three most-ambitious pathways, #GlobalWarming has a 50% chance of either staying below 1.5C, or overshooting it by only 0.1C (for up to several decades) before then returning to below 1.5C.

Yet, not only are atmospheric #CO2 concentrations still rising, the rate of rise is #accelerating.
The build-up of CO2 in the #atmosphere has been monitored at the #MaunaLoa observatory in #Hawaii since 1958.
As illustrated by the iconic #KeelingCurve below, the increase has been accelerating over the decades (blue line) due to ongoing emissions of CO2 from burning #FossilFuels and changing land use.
So while the curve needs to rapidly bend in the other direction to hold warming to 1.5C (light red line), the rate of rising CO2 marches onwards and upwards.

Senate Confirms #LeeZeldin to Head #EPA where hes charged with executing Trump’s orders to dismantle #environmental #regulation
Former NY congressman has little experience in environmental policy. He is expected to follow orders to weaken #climate rules. One rule, finalized last year, would cut #tailpipe #emissions of #greenhousegas, nation’s largest source of planet-warming #pollution, by compelling #automakers to increase sales of hybrid and EV.

Ocean-surface warming has more than quadrupled since the late-1980s, study shows

The rate of #ocean #warming has more than quadrupled over the past four decades, a new study has shown. Ocean temperatures were rising at about 0.06°C per decade in the late 1980s, but are now increasing at 0.27°C per decade.
Published 28 January 2025 in Environmental Research Letters, the study helps explain why 2023 and early 2024 saw unprecedented ocean temperatures.
This #accelerating ocean warming is driven by the Earth's growing energy imbalance—whereby more #energy from the sun is being absorbed in the Earth's system than is escaping back to space. This imbalance has roughly doubled since 2010, in part due to increasing #GreenhouseGas concentrations, and because the #Earth is now reflecting less sunlight to space than before.
Global ocean temperatures hit record highs for 450 days straight in 2023 and early 2024. Some of this warmth came from #ElNiño, a natural warming event in the Pacific.
