Alaska’s Creepy Bubbling Lakes

‘Every single month of 2016 has been the hottest on record, and this uptick in temperature is sure to have wide-ranging consequences around the world. One of the weirdest and least understood of these climate-related side effects is that Arctic boreal lakes are boiling over with methane bubbles. Indeed, some of these areas are such rich producers of methane that scientists can light plumes of the lake’s escaped gas on fire.

These gassy lakes are created by thawing permafrost, which is soil that normally remains frozen all year. But warmer temperatures have caused more permafrost to melt, causing the ground around it to collapse into water-filled sinkholes called thermokarst lakes.’
