With climate change, US ecosystems have shifted hundreds of miles north.

Researchers in Nebraska analyzed 46 years’ worth of bird data collected for the North American Breeding Bird Survey, a program designed to track bird populations. The survey discovered the areas where specific species of birds lived had changed across the United States. Researchers found that coinciding with climate change, the habitats of birds have shifted. The northernmost ecosystem shifted more than 366 miles north – the length of an entire state. The southernmost boundary moved about 160 miles northward. The northernmost ecosystem shifted more than the southernmost area because of a well-known phenomenon known as Arctic amplification. Arctic amplification, or polar amplification, is a phenomenon that any change in the balance of solar radiation across the plant tends to produce a larger change near the…

How does global warming cause changes to our normal weather patterns?

The jet stream drives weather patterns The jet stream is a strong wind current flowing about 10 miles above the ground. In the Northern Hemisphere, it almost always blows from west to east and always in a fairly straight line. The jet stream is extremely important to weather systems – it drives the weather patterns throughout the year. The strength of the jet stream, and to what degree it impacts our weather, is determined by the temperature difference between the Arctic and the southern half of the world. CO2 causes temperatures to rise The level of CO2 in our atmosphere has been measured atop the Mauna Loa volcano in Hawaii since around 1958. At the time measurements began, the CO2 measured 315 parts per million…

This company is trying to solve climate change by using giant machines to suck CO2 out of the air.

As we consume oil (by driving cars) and coal (by generating electricity) that we extracted from the ground, it releases large amounts of carbon dioxide into the atmosphere which causes our planet to heat up. Kids around the world say the same thing – “Let’s just remove all the carbon dioxide from the air and put it back into the ground where it came from.” Meanwhile, scientists pooh-poohed the “silly idea” saying, “They’re just kids! What do they know!” Well today kids can triumphantly raise their fists in the air and shout “We told you so!” A company out of British Columbia has created a machine that can suck carbon dioxide out of the atmosphere and put it back into the ground! The company is…
