Scientists point to accelerating release of CO₂ from rocks in Arctic Canada due to global warming

Researchers from the University of Oxford's Department of Earth Sciences have shown that rock weathering in the Canadian Arctic will accelerate as temperatures rise, triggering a positive feedback loop that will release more and more CO 2 into the atmosphere. The findings were published in the journal Science Advances. For sensitive regions such as the Arctic, where surface air temperatures are warming nearly four times faster than the global average, understanding the potential contribution of atmospheric CO 2 from weathering is particularly important.
