To combat climate change, human activities more important than natural feedbacks

To combat climate change, human activities more important than natural feedbacks

February 21, 2020

Permafrost in the soil and methane hydrates deep in the ocean are large reservoirs of ancient carbon. But even if methane is released from these large natural stores, new Rochester data shows that the bigger concern is methane released from human activities.

Researchers solve ‘hot spot’ debate

July 31, 2019

Volcanic hot spots such as the ones that created the Hawaiian Islands have long been considered stationary points, but new data analyses provide conclusive evidence that hot spots are not fixed but are moving.
