Last week I asked if an historical version of @climatetrunk.bsky.social’s breakdown of annual emissions would be useful. The answer was an emphatic yes. Some familiar names loom much larger. @skepticalscience.bsky.social @visualisingclimate.com www.climatetrunk.com/infographics...
Just 35 companies can be linked to 40% of global CO2 emissions since 1854. CO2 emissions accumulate in the atmosphere over time. Today’s heating reflects the stock that has built up over generations – about 1.2 trillion tonnes.
