Psst: Stop burning stuff on Earth for energy. Let the burning fireball in the sky be your energy source.
NEW: Biofuels globally emit more than the fossil fuels they replace, our latest study shows.
The first-of-a-kind study looks at global biofuels production today and the potential impacts of government biofuel targets.

Just remembered this jaw-dropping graph by @oceansclimatecu.bsky.social showing the rate of change in CO2 during the previous two deglaciations of the Pleistocene (which, as a fun aside, featured ~400 feet of sea level rise) as compared with today

In recognition of us doing fuck all to reduce emissions, let me remind y'all that carbon dioxide removal (CDR) is useless unless we decarbonize drastically.

Carbon dioxide removal is not a current climate solution — we need to change the narrative
Drastically reduce emissions first, or carbon dioxide removal will be next to useless.

I checked the claim of the DOE report that sea level is rising at a lower rate than predicted by IPCC: it is false.
For 2030, the IPCC AR6 predicts a best estimate 9-10 cm relative to 1995-2014 (Table 9.9).
The satellite data show a rise of 74 mm until 2025. At this rate that will be 93 mm by 2030.

Earth’s energy imbalance has more than DOUBLED in 20 years.
So, just a gentle reminder that most of our politics & media is a distraction, because most of our politics & media is owned by the fossil-fueled corporations profiting from boiling us alive.

Don’t buy the polished crap from the White House. Texas flood deaths weren’t a surprise...they were the price of gutting services. Cut first responders...ignore warnings...and act shocked when people die? That’s not weather. That’s political manslaughter.

Congress abdicated its role as a separate and independent branch of government on January 20 while also relinquishing all oversight responsibility, so it’s entirely appropriate for Johnson to show that he has surrendered his gavel to the executive.

I don’t think anyone is prepared for what they just did w/ ICE.
This is not a simple budget increase. It is an explosion - making ICE bigger than the FBI, US Bureau of Prisons, DEA,& others combined.
It is setting up to make what’s happening now look like child’s play. And people are disappearing.

Susan Collins has voted 3 times TODAY to strip health care from Mainers. When given the chance to protect Medicaid and affordable health care for Mainers, she sided with her party instead.
