Global warming: The missing energy

It was autumn 2009 when I first started writing my BBC Weather and Climate blog.

 

My initial articles created huge interest around the world. They aimed to highlight the fact that global temperatures had levelled off at elevated levels, despite ever rising levels of greenhouse gases, a situation which remains unchanged nearly four years later.

 

At the time there seemed to be a reluctance to acknowledge such a levelling off in global temperatures, although this is no longer the case.

 

But Dr Kevin E Trenberth of University Corporation for Atmospheric Research (UCAR) was one climate scientist at the time who did acknowledge this apparent lack of warming in surface temperature observations.

 

It’s now described as the issue of ‘missing energy’ – namely with rising levels of greenhouse gases, where has the expected extra global warmth, which basic physical laws predict, gone?

 

It is, for obvious reasons, a subject of great interest to readers of this blog, and I thought a recent article I read would be of interest.

 

It’s been written by the very same Dr Kevin E Trenberth, who was quoted a year later in 2010 as saying, ‘the heat will come back to haunt us sooner or later. The reprieve we’ve had from warming temperatures in the last few years will not continue. It is critical to track the build-up of energy in our climate system so we can understand what is happening and predict our future climate.”
