NOAA’s own trend calculator helps confirm ‘the pause’ and lack of ocean warming in the 21st century

People send me stuff. Yesterday I got a note suggesting I have a look at what NOAA/NCDC’s “climate at a glance” was showing for trends in the 21st century so far. I decided to take a look.

New paper finds the climate to be ‘highly nonlinear’

But, we already knew that from experience. However, a lot of models still treat climate as a mostly or near linear process, and that’s why they aren’t performing particularly well at even predicting the present. (via the Hockeyschtick) A paper … Continue reading
