The Arctic's indigenous people have a long relationship with its icy conditions, and face the loss of their cultural heritage. Further, there are numerous implications which go beyond the Arctic region. Sea ice loss not only enhances warming in the Arctic but also adds to global temperature increase through the ice-albedo feedback.
Much of the United States is shivering through brutal cold as most of the rest of the world is feeling unusually warm weather. Wind chills in parts of North Dakota reached minus 70 degrees (minus ...
Recent warming has driven many terrestrial and freshwater species poleward and towards higher altitudes. [215] For instance, the range of hundreds of North American birds has shifted northward at an average rate of 1.5 km/year over the past 55 years. [216] Higher atmospheric CO 2 levels and an extended growing season have resulted in global ...
The Arctic Ocean is the mass of water positioned approximately above latitude 65° N. Arctic Sea Ice refers to the area of the Arctic Ocean covered by ice. The Arctic sea ice minimum is the day in a given year when Arctic sea ice reaches its smallest extent, occurring at the end of the summer melting season, normally during September.
Things are heating up at the top of the world about four times faster than the rest of the globe, according to new research on the Arctic, where some of the.
The Arctic experienced the warmest summer on record this year, contributing to extraordinary wildfires and melting glaciers while threatening the rest of the world with problems including higher ...
From ancient times, people suspected that the climate of a region could change over the course of centuries. For example, Theophrastus, a pupil of Ancient Greek philosopher Aristotle in the 4th century BC, told how the draining of marshes had made a particular locality more susceptible to freezing, and speculated that lands became warmer when the clearing of forests exposed them to sunlight.
A 2016 Gallup poll found that 64% of Americans were worried about global warming, that 59% believed that global warming was already happening, and 65% were convinced that global warming was caused by human activities. These numbers show that awareness of global warming was increasing in the United States. [302]
