"Over the course of March, the nation got more electricity from renewables than it did from natural gas, which is typically the single-largest source of energy on the U.S. grid. It’s the first time renewables have bested the fossil fuel in the U.S. across an entire month"

Unsurprising, but... "Delta deleted its pledge to use sustainable aviation fuel (SAF) for 10% of its jet fuel by 2030. It also rephrased its quest to achieve net-zero emissions by 2050 as an 'aspiration,' rather than a 'goal.'"

Holy smokes! An incredible start to the 'Wildfire Season' in the US this year - owing to an abnormally hot and snowless winter in some parts of the country.

Why is there poo on the Moon? - BBC Science Focus Magazine Who knows what could have become of the poo left on the Moon?

🌓Went down a little rabbit hole about space flight to the moon yesterday after the launch, and I was surprised to learn there actually 96 bags of human excrement that were left there. How nice. 6 US flags, and 96 bags of 💩

Sweet! I just received funding along with a great bunch of fellow researchers to study the 'societal costs' of climate change (broadly defined). We will be looking at how the impacts of climate change, fossil fuel dependency, and even climate policies themselves might incur 'costs' on society 👍

Effectively... don't rule out 'worst case scenarios': "This bolsters the argument that to avoid climate-related risks to systems that are key for global food security and ecosystem functioning, effective policy should take into account worst-case scenarios as well as average projections."

There is a more detailed interactive map at the Climate Impact Lab site where you can click on your specific district to see the expected change in mortality where you live by 2050 (relative to 2001-2010 average). Where I live mortality is expected to decline.
