Understanding temperature change since the pre-industrial period is essential for climate action. This study uses an ocean proxy to better quantify when anthropogenic warming began and estimates that global temperatures have already increased by 1.7 °C.
This is such a contentious paper, academics fighting over whether that’s the accurate way to record or measure changes in temperature as we were in a particularly cold period and we shouldn’t be counting before we were dumping more CO2 into the environment and yet, any data is good data and should give us a more complete look at our scenario.
That being said I get why people would want to argue that we aren’t past 2° or are past 2° for personal belief reasons and that adds a personal spin to this paper for those reading it. I think the line doesn’t really matter as much as the response and the current situation.
The response has been fighting and no action and the current situation is if you are rich you can ignore it. So that’s not great.
