Climate Change

There Is No Pause

The Intergovernmental Panel on Climate Change (IPCC) have today released the Fifth Assessment Report’s (AR5) Summary for Policymakers (SPM) from their Working Group 1 (WG1), those who have reviewed the science basis.

The world is certainly warming, and it is virtually certain that mankind is the dominant cause since 1950.

Plus, there’s no apparent hiatus in global warming. There is no pause.

The report reads to me to say that although air temperatures near the surface of the Earth have not changed much in the last 15 years, the trends for temperature in the combined land and ocean data sets show a clear upwards movement overall, with the usual jiggledyness of natural system data, sometimes a little up here, sometimes a little down there, but overall rising.

Of note, word from the IPCC Press Conference and related commentary is that in some regards, there is simply not enough data to be 100% comprehensive in reporting on temperatures. And yet despite that, the picture on global warming is still remarkably sharper than in 2007.

There should no longer be any fence to sit on as regards climate change.
