    It is important to gather detailed data on the CO2 sinks and sources to determine how they change over time, which can have an influence on the Earth's temperature. CO2 is one of the major greenhouse gasses that make our Earth livable.

  • See how much Lake Mead levels drop in just one year in images snapped from space

    See how much Lake Mead levels drop in just one year in images snapped from space

    Wednesday, August 6 2014 10:32 AM EDT2014-08-06 14:32:32 GMT
    Lake Mead began filling with water in May of 1937 upon completion of the Hoover Dam. After over two years of water flowing into the lake, water levels reached 1080', an important number for water managers. That number ensures states taking water out of Lake Mead have a consistent water source, and that the Hoover Dam hydroelectric power plant has enough water to function properly.

    It's a beautiful afternoon, and you're outside in the park. Then, a powerful thunderstorm moves in within minutes. There are no nearby structures or buildings for shelter, but your car is nearby so you make a run for it. After all, the tires will protect you from lightning strikes, right?  Wrong. It's an idea that was first thought of in the late 1800s, on bicycles.
