Warming Pause Research Continues

Leave a comment

By my count, there are four leading scientific explanations for the short-term slowdown overlaying the long-term rate of global surface warming.  They are:

Enhanced heat uptake by the world’s oceans, especially over the Pacific due to enhanced easterly winds

Sustained small to medium-sized equatorial volcanic activity

Slightly reduced solar irradiance

Natural variability, including the Interdecadal Pacific Oscillation

One interesting aspect to  these explanations’ presence is most researchers believe their explanation is the leading one.  It is a symptom of the state of climate science:  specialization proliferation leads to poor cross-disciplinary communication.  Someone might have this within their purview, but I am currently unaware whether anyone is apportioning relative causality of these explanations together.  Attribution is challenging, of course, but such an effort seems worthwhile to me.

Some recent science updates on these explanations:
