There’s a persistent myth that new solar farms don’t really help tackle climate change because panels are “made with coal” and “never pay back” their carbon debt.

This is simply false.

- UN: solar ~8x cleaner than gas, ~19x than coal per kWh
- panels repay CO2 in 4 months; save 57x over life

Not good.
Cuts announced now at NASA and it's going well beyond DEI and affecting strategy, policy and well, the things that should help inform the public and politicians about taxpayer funded science, so it's all a bit confusing to me. 🧪🔭

🔥 Fire suppressants leave a toxic legacy

A new study finds that wildfire retardants contain toxic metals (up to 2,880× drinking water limits).

This has contributed up to 380,000 kg of contamination in the U.S. since 2009.

The current state of chaos in the US government is directly proportional to the amount of people who have no to little experience working in a large complex field. This is what you lose when you over simplify.

Who’d have thought that making a hand gesture associated with nazi Germany might have a negative impact on share price. ( I know it is other factors most likely, but I can dream)

I’m surprised how many scantily clad women with no posts seem to be interested in climate change, EVs and space over the past couple weeks. Very encouraged.
