Methane trapped in ice above a peat bog
Air bubbles and methane trapped in ice above a frozen peat bog in the Lake district UK Methane is 20times more effective as a greenhouse gas than C02 and is starting to be released in huge quantities as global warming indiuced rising temperatures cause permafrost to melt and peat bogs to turn from carbon sinks to net contributers of greenhouse gases This is one of the feedback loops that could mean we end up in a situation of runaway warming
