Hard water lakes such as the Buffalo Pound Lake in Saskatchewan, are common in the Prairie provinces. Boreal lakes normally emit greenhouse gases with the breakdown of organic matter. New research shows that atmospheric warming could transform these lakes into carbon sinks. This study contradicts the general assumption that global warming will invariably increase CO2 emissions from […]

Carbon quotas are nearly used up
Two upcoming papers discuss the concept of a carbon quota, that is, a limited amount of carbon that can be released to the atmosphere in order to remain below a certain global warming target. The first paper, published in Nature Geoscience, indicates that we have already used up two thirds of the carbon quota needed […]
Wind in Southern Ocean influences mixing of the deep ocean
A new study shows that winds in the Southern Ocean near Antarctica influence the rate at which deep ocean waters – which act as a key reservoir for heat, carbon and nutrients – mix with the shallower waters above them. Using data from 20 years worth of satellite and probe-based measurements, researchers mapped out how […]
