Launched in collaboration with U. In the Amazon, for example, the tool shows large swaths of forest traded for cattle ranches and soybean farms. In Greenland and Antarctica, users can see miles-long glaciers quickly melting away. Wildfire smoke fills the skies above Alberta, Global warming articles national geographic the coast of the Bahamas is devastated by a hurricane; and the Aral Sea in Kazakhstan loses 90 percent of its surface area in a matter of decades.
The tool also shows how landscapes have changed as humans have demanded more energy. The user can witness fracking well pads popping john strengths on the North Dakota landscape and mountaintop mining turning West Virginia forests from green to brown.

So all of our actions are connected. Researchers detailed their discovery in a recent study published in the Journal of Geophysical Research: Biogeosciences.
When the climate was colder and wetter, continue reading tended to eat more insects, while during warmer, drier periods, bats favored fruit. Understanding how bats adjusted to climate changes helps researchers understand how bats might be affected in the future by global warming.

It also shows a beluga whale pod caring for a young narwhal, documenting the first known cross-species adoption.

A massive brood of cicadas is poised to emerge any day now in the eastern United States, and cicada researchers are gearing up to study the phenomenon that comes once every 17 years.
Brood X, which last emerged inis one of the biggest groups of periodical cicadas. Trillions of bugs known for their loud global warming articles national geographic and buzzing will quickly hatch, mate and die this spring, from Washington, D. John Cooley, a cicada researcher with the University of Connecticut, studied the emergence and plans to create a detailed map of the emergence.
But the cicada is a relatively old insect, with lineages dating back 5 million years, Cooley said.]
