On the likelihood of recent record warmth

by Judith Curry

[O]ur results suggest that the recent record temperature years are are roughly 600 to 130,000 times more likely to have occurred under conditions of anthropogenic than in its absence.  – Mann et al.

Huge efficacy of land use forcing in one GISS-E2-R simulation: is an ocean model error involved?

by Nic Lewis

In a recent article here, which summarised a longer piece at ClimateAudit, I discussed the December 2015 Marvel et al.[1] paper, which contends that estimates of the transient climate response (TCR) and equilibrium climate sensitivity (ECS) derived from recent observations of changes in global mean surface temperature (GMST) are biased low.

Climate models versus climate reality

by Pat Michaels and Chip Knappenberger

Perhaps the most frank example of the growing disconnection between forecast and observed climate change was presented by University of Alabama’s John Christy to the Senate Subcommittee on Space, Science, and Competitiveness Committee of the U.S. House of Representatives on December 8.

New research on atmospheric radiative transfer

by Judith Curry

Three new papers highlight how atmospheric radiative transfer, particularly how it is treated in climate models, is not ‘settled science.’

Questioning the robustness of the climate modeling paradigm

by Judith Curry

Are climate models the best tools? A recent Ph.D. thesis from The Netherlands provides strong arguments for ‘no’.

Applications of subseasonal weather forecasts

by Judith Curry

There is growing interest in the scientific, operational and applications communities in developing forecasts that fill the gap between medium range weather forecasts (up to two weeks) and seasonal forecasts (3-6 months).
