As spring advances, so does the rain to warm the permafrost. It means more methane can get into the atmosphere to accelerate global warming.<\/strong><\/p>\n\n\n\n

LONDON, 18 February, 2019 \u2212<\/em> As the global temperature steadily rises, it ensures that levels of one of the most potent greenhouse gases are increasing in a way new to science: the planet will have to reckon with more methane than expected.<\/p>\n\n\n\n

Researchers who monitored one bog for three years in the Alaskan permafrost have identified yet another instance of what engineers call positive feedback. They found that global warming meant earlier springs and with that, earlier spring rains.<\/p>\n\n\n\n

And as a consequence, the influx of warm water on what had previously been frozen ground<\/a> triggered a biological frenzy that sent methane emissions soaring.<\/p>\n\n\n\n

One stretch of wetland in a forest of black spruce in the Alaskan interior stepped up its emissions of natural gas (another name for methane) by 30%. Methane is a greenhouse gas at least 30 times more potent than carbon dioxide.<\/p>\n\n\n\n

\u201cThe microbes in this bog on some level are like \u2018Oh man, we\u2019re stuck making methane because that\u2019s all this bog is allowing us to do\u2019\u201d<\/strong><\/p><\/blockquote>\n\n\n\n

As a consequence, climate scientists may have to return yet again to the vexed question of the carbon budget, in their calculations of how fast the world will warm as humans burn more fossil fuels, to set up ever more rapid global warming and climate change, which will in turn accelerate the thawing of the permafrost.<\/p>\n\n\n\n
