Arctic Methane Monster

The Intergovernmental Panel on Climate Change (IPCC) has just released the Summary for Policymakers of Working Group I.

Sadly, the document contains little or no warning on the looming Arctic Methane Monster.

The IPCC does warn that people's emissions of carbon dioxide (CO2) must be reduced to avoid dangerous temperature rises.

The IPCC does add that "accounting for warming effects of increases in non-CO2 greenhouse gases, reductions in aerosols, or the release of greenhouse gases from permafrost will also lower the cumulative CO2 emissions for a specific warming target".

Yet, the IPCC fails to warn that huge amounts of methane, contained in sediments under the Arctic Ocean, are ready for release any time.

There are no warnings about high sea surface temperatures in the Arctic Ocean. In August 2013, sea surface temperatures of over 20°C (68°F) were recorded in some areas in the Beauford Sea and up to 18°C in the Bering Strait. Even this late in the melting season (September 28, 2013), sea surface temperatures of over 12°C are still recorded close to Svalbard (image right), in an area where methane hydrates are known to have become destabilized over the past few years. There are no warnings that, wherever the sea ice retreats, sea surface temperature anomalies are coloring the Arctic Ocean scarlet red, with temperature anomalies of over 4°C all over the place (image below). No warnings that earthquakes can destabilize hydrates that have become vulnerable due to temperature rises.

This lack of warning gives the false impression that the situation could only become dangerous until after decades of further emissions.  

Indeed, the IPCC acts as if there was a carbon budget to divide among countries, whereas the reality is that there is a huge carbon debt to our children, while the situation could become catastropic any time soon. It appears that the IPCC has been trying desperately to please those with vested interests in maintaining the status quo.

In reality, the situation calls for comprehensive and effective action, such as proposed at the ClimatePlan blog.
