How 19th Century Scientists Predicted Global Warming - JSTOR Daily
Today’s headlines make climate change seem like a recent discovery. But Eunice Newton Foote and others have been piecing it together for centuries.
daily.jstor.org
Climate Science made simple, 169 yrs ago, by a woman.
“In an 1856 issue of TAJS, Eunice Foote made an eerily prophetic observation: What happened inside the CO2 jar could also happen to our planet. “An atmosphere of that gas, would give to our earth a high temperature.”
C Thompson, 2019, in JSTOR

The rise of battery storage, and why the grid is rapidly passing gas!
Although batteries still account for a modest share of total capacity, they are exerting a disproportionate influence in Australia's main grids.

Ocean heat content increased by 23 billion trillion joules, which was around 39 times greater than global primary energy use this year. This is the largest rise in OHC since 2017; overall OHC has increased by over 500 zettajoules since the 1940s.
