The Arctic’s thawing ground is releasing a shocking amount of dangerous gases

by Craig Welch, National Geographic


Highlights:

Abrupt thaw, the accelerated melting of permafrost, is releasing GHGs in the arctic:

  • New studies on abrupt thaw suggest that permafrost will play a more significant role in GHG emissions than previously believed . However, it’s affects are small compared to the burning of fossil fuels throughout the world
  • The warming of ice and arctic grounds will cause changes in landscape which can result in more moisture being released, more water bodies forming, and ultimately, the release of methane previously trapped in the land 
  • Previous IPCC assessments haven’t incorporated permafrost emissions in their reports; accelerating the need to meet emissions targets at a faster rate

Because of the alarming climate impacts we are experiencing much earlier than expected, The Climate Center supports carbon neutrality by 2030 and net negative emissions by 2035. Find more information on accelerating timelines for rapid decarbonization here.

The IPCC global warming report spares politicians the worst details

by Bob Ward, The Guardian

A report by the Intergovernmental Panel on Climate Change confirms the enormous wisdom that governments showed in Paris in December 2015, when they agreed to the goal of “pursuing efforts” to limit global warming to 1.5C.

The report’s summary for policymakers paints a sobering picture of the potentially terrible impacts of allowing global mean surface temperature to rise by 2C compared with pre-industrial levels: more extreme weather, sea level riseand ocean acidification, with detrimental effects on wildlife, crops, water availability and human health.
