The new open thread on climate science for a new year, and a new decade – perhaps the Soaring Twenties? What precisely will be soaring is yet to be decided though.

Two things will almost certainly go up – CO2 emissions and temperatures:

But maybe also ambition, determination, and changes that will lead to reduced emissions in future? Fingers crossed.

This month’s open thread for climate science topics. A new two-part community assessment of tropical storms and climate change is online at BAMS: Knutson et al. (2019a ; 2019b). And for those interested in Arctic Sea Ice, there is always the NSIDC.

This month’s open thread on climate science topics. Arctic sea ice minimum is upcoming, global temperatures running at (or close) to record levels, heat waves, new reconstructions for the last 2000 years, etc… Surely something there to discuss?
