Mrs. Eunice Newton Foote (1819-1888) was a women& #39;s rights advocate & pioneering scientist. In 2020, @EarthSci_Info + @Roland_Jackson reanalyzed the data from her groundbreaking 1856 study to show you could estimate a climate sensitivity of 2-3C from it! https://royalsocietypublishing.org/doi/10.1098/rsnr.2020.0031">https://royalsocietypublishing.org/doi/10.10...
Climate sensitivity is the equilibrium change in global mean temperature resulting from a doubling of CO2 relative to pre-industrial levels. It& #39;s usually represented as a probability distribution with a mean value around 2.4-4.7. Here is a recent review: https://agupubs.onlinelibrary.wiley.com/doi/pdfdirect/10.1029/2019RG000678?fbclid=IwAR0RaslfRZtPcbi_RjZS3wnHWralh0GuoMyJ9NSbgAOOezP0VyTHgrfdlrs">https://agupubs.onlinelibrary.wiley.com/doi/pdfdi...
Why don& #39;t we know the value for sure? Because we& #39;ve never seen this much carbon going into the atmosphere this fast with these precise initial conditions. We are conducting a truly unprecedented experiment with our planet. https://iopscience.iop.org/article/10.1088/1748-9326/11/12/120202">https://iopscience.iop.org/article/1...
But Eunice Foote& #39;s values - given the fact that they were obtained from pumping gas into glass tubes in her home laboratory in 1855 - are right in that ballpark and, as such, truly amazing.
Her paper was read by Joseph Henry, first Secretary of the Smithsonian, at the annual @aaas meeting in 1856. Why didn& #39;t she read it herself? We don& #39;t know; women were allowed to, and she did read her very next paper at AAAS the following year. https://static1.squarespace.com/static/5a2614102278e77e59a04f26/t/5aa1c3cf419202b500c3b388/1520550865302/foote_circumstances-affecting-heat-suns-rays_1856.pdf">https://static1.squarespace.com/static/5a...
Some fun Eunice trivia: her maiden name is no accident; she is indeed a distant cousin of Sir Isaac Newton. And the Foote family has also produced modern-day scientists @footesea and @howarth_cornell. In 2020 @jswatz

And last but not least, @allwecansave, the inspirational collection of essays + poems by women in climate, kicks off with Eunice& #39;s story. If you don& #39;t have your copy yet - or are looking for good Christmas presents - I recommend it HIGHLY. http://allwecansave.earth/ ">https://allwecansave.earth/">...
