Congratulations (finally) to Spencer and Braswell on getting their new paper published

WUWT provided a primer on cloud feedbacks on June 12th, 2009, followed by Willis Eschenbach’s “thermostat hypothesis” also recently published. This new paper by Spencer and Braswell is in the…

"Unaccounted feedbacks": to B or not to B

University of Helsinki via Eurekalert Unaccounted feedbacks from climate-induced ecosystem changes may increase future climate warming The terrestrial biosphere regulates atmospheric composition, and hence climate. Projections of future climate changes…
