New research by McGill University biologists shows that milder winters have led to physical alterations in two species...
A new study sheds light onto the global warming "hiatus" of 1998-2013. The authors conclude the phenomenon represented a redistribution of energy within the Earth system, with Earth's ocean absorbing the extra heat.
