How global warming is actually helping the swan community

How global warming is actually helping the swan community

The Arctic has a history of amplifying global temperature changes, warming or cooling faster than the rest of the planet. Recent trends are no exception: While the globe on average has warmed 0.6 degrees Celsius compared to historic norms, the Arctic has jumped 1.5 degrees Celsius, with some areas approaching 3 degrees Celsius warmer. Higher spring temperatures are causing the earlier snowmelt, and the timing of that melt influences the warming of the atmosphere. Reduction of the snow cover in the region over those days, researchers found, magnified the heating effect three times.
