Summer is Coming

A recent computer model based study published in Proceedings of the National Academy of Sciences predicts the impact of biomass CO2 releases from thawing permafrost may be an even larger problem than previously expected, transitioning from a carbon reducing ecosystem to a carbon producing system by the end of the century.

Of course, since this is just a model based study the results will have to be confirmed in the field before the situation merits screaming “The End is Nigh.”

 The study disagrees with previous permafrost models that predicted future vegetation in the former tundra would soak up enough carbon to induce a net carbon loss of the permafrost system but that may not be the case as several hundred years’ worth of decay finally gets some fresh air.
