protonsforbreakfast.wordpress.com/2025/06/17/h... Assessing whether a particular temperature measurement is "hot" is really a question about context: regional, seasonal, and time of day. @edhawkins.org has a new web site that presents current temperature measurements in a meaningful context.

#scam I paid @Climeworks £1,650 to remove 2 tons of CO2 from the atmosphere. Was I a gullible idiot? Yes. Icelandic newspaper @heimildinhas shown that they not only haven’t captured my 2 tons, they don’t even capture their own emissions heimildin.is/FGY3 via @heimildin

protonsforbreakfast.wordpress.com/2025/05/11/s... Both my children are now in gainful employment, so I thought I would look back at whether student loans make any more sense now than they did when children went off to university. My conclusion is that it still seems bonkers and unsustainable.

www.youtube.com/watch?v=OEMQ... Fascinating historical perspective by @chrisjardineenergy.bsky.social of the growth of solar PV in the UK. Really interesting to the see the interplay of price, subsidies, installer base and the change in the economics of domestic installations.

protonsforbreakfast.wordpress.com/2025/04/14/t... I used a model by @daanwalt3r.bsky.social (Daan Walters) to investigate how the cost of 1 GW of firm electricity varies in a plant with various combinations of gas, solar PV and batteries. Adding Solar PV makes electricity cheaper!
