PARIS (AFP) — New studies have warned of triggers in the natural environment, including a greenhouse-gas timebomb in Siberia and Canada, that could viciously amplify global warming.

Thawing subarctic tundra could unleash billions of tonnes of gases that have been safely stored in frosty soil, while oceans and forests are becoming less able to suck carbon dioxide (CO2) out of the atmosphere, according to papers presented this weekend.

Together, these phenomena mean that more heat-trapping gases will enter the atmosphere, which in turn will stoke global warming, thrusting the machinery of climate change into higher gear.
