A new study by CLEX researchers and colleagues shows that CMIP5 models as a group, when forced by observed sea surface temperatures underestimate, these atmospheric feedbacks on average by 23%. This underestimate can be linked to the wrong location at which climate models simulate the most important tropical circulation, called the Walker circulation.

Natural variability has been found to play a role in the speed of warming of land surface temperatures. With indications that the negative Interdecadal Pacific Oscillation is now becoming positive, this suggests that the hiatus period is over and we are likely entering a phase of accelerated warming of global surface air temperatures.
