Climate change has been in the news recently, in spite of the winter weather in America and England. but is the weather caused by carbon dioxide or is there something that most scientist do not understand.

As the Arctic gets warmer, large quantities of greenhouse gas could be released from the sediment at the bottom of lakes, a source that has previously been overlooked.

The frozen soil of the Arctic has already started to thaw, triggering the release of more methane and carbon dioxide into the atmosphere. This climate feedback is well known, but most modelling only accounts for thawing in the top 3 metres of Arctic soil.”
