Report: Permafrost thawing could accelerate global warming


Melting Siberian permafrost threatens major methane release

It could take as little as a 1.5 degree rise in global temperature to thaw Siberia permanently, potentially releasing catastrophic levels of cartbon dioxide and methane from the soil.

Sunlight ramps up CO2 production from permafrost

It appears that, when Arctic permafrost melts, it can release carbon dioxide gas into the atmosphere much faster than previously thought.

Melting permafrost is ticking time bomb, says UN

The permafrost covering almost a quarter of the northern hemisphere contains twice as much carbon as is currently in the atmosphere, and could significantly amplify global warming should thawing accelerate as expected.

Thawing permafrost could lead to massive carbon release

As much as 44 billion tons of nitrogen and 850 billion tons of carbon stored in arctic permafrost could be released into the environment over the next century by the effects of global warming.

Thawing permafrost affects climate more than thought

As the Arctic warms, thawing permafrost will release greenhouse gases  faster and in greater amounts than previously believed.

Antibiotic resistance is thousands of years old

Antibiotic-resistant bacteria are nothing new - they've been around for at least 30,000 years, say scientists at McMaster University.

Melting permafrost could ramp up global warming

Thawing permafrost could release billions of tons of carbon into the atmosphere by the end of this century, further accelerating global warming.
