Born On Frozen Lakes
The National Hockey League seems like an unlikely environmental ally. But a sport born on frozen lakes stands to lose a lot in a warming world. NHL Commissioner Gary Bettman is committed to keeping “the air clean and the ponds frozen for future generations.”
Climate Opinions
An international poll of over 45,000 people in 40 countries looked at opinions about climate change and the need to curb greenhouse gas emissions. The results are quite interesting.
Cod And Global Warming
Atlantic cod has been the basis of a major fishing industry in the Gulf of Maine for centuries and is a key species in the local ecosystem. Overfishing decimated the population of cod and in 2010, fisheries managers imposed a series of restrictions on harvesting the fish in order to try to help the species to rebound.
Climate Change And Extreme Weather
Global climate change is predicted to manifest itself in many ways over the next 100 years as average temperatures increase around the world. But we do not directly experience climate; we experience weather.
Plugging Methane Leaks
Natural gas, also known as methane, is one of several “greenhouse gases” that trap heat radiation trying to leave the Earth. Molecule-for-molecule, methane warms our planet’s atmosphere about 25X more than carbon dioxide.
The Missing Sink
One of the puzzles of atmospheric chemistry is why carbon dioxide concentrations in our atmosphere aren’t rising even faster. Our activities emit some 37 billion metric tons of carbon dioxide each year. About 45% stays in the atmosphere, 25% is taken up by the oceans. The rest is a bit of a mystery.
Locked In A Pattern Of Arctic Ice Loss
There is no dry land at the North Pole and under much of the Arctic ice pack. There, the ocean is covered with sea ice. When this ice melts, it does not cause a rise in sea level, the same way ice cubes melting in your water glass don’t cause it to overflow.
Breeding Super Corals
The world’s coral reefs are increasingly threatened by the changing climate. Both warmer ocean temperatures and increasing ocean acidification are damaging coral populations and endangering the very existence of coral reefs.
Wikipedia: Especially Unreliable for Politically Controversial Science Topics
Wikipedia is world’s most popular online encyclopedia, the sixth most visited website in America, and a source most students rely on. But, according to a recent study, Wikipedia entries on politically controversial science topics can be especially unreliable.
