    Atmospheric CO2 Level Tops 400 ppm

    During the week of May 13th, the CO2 level at the Mauna Loa Observatory in Hawaii topped 400 ppm repeatedly. Daily levels of CO2 can vary due to weather, and there are seasonal trends as well. The level of atmospheric greenhouse gases continues to increase, now over 120 ppm since the Industrial Revolution began. For more on the Keeling Curve, see http://keelingcurve.ucsd.edu/.

    Massive Tornado Outbreak on Tornado Alley

    The week of May 19 brings dozens of tornadoes to Tornado Alley in the states of Oklahoma, Kansas, Iowa, Illinois and Missouri. On May 20th, a massive tornado struck Moore, Oklahoma, devastating communities - destroying over 100 homes and hitting two elementary schools and a hospital - with many casualties and deaths. Our thoughts are with our friends and colleagues suffering from these storms. For more on the May 20th storms, see the NOAA Storm Prediction Center Storm Report.

    Kansas Legislator Proposes Bill to Outlaw Sustainability Education

    A bill has been introduced in the Kansas legislature this week that would prohibit the promotion of sustainability. Here is a link to the one-page bill: http://www.kslegislature.org/li/b2013_14/measures/documents/hb2366_00_0000.pdf. See report on Bloomberg News.

Arctic Tundra Carnivores

The tundra is full of carnivores, animals that eat meat. Bears, wolves and even bats fill the tundra with life. Let's explore these creatures further!

There are several species of bear in the tundra. Polar bears usually live farther north, but are also found in the tundra searching for food. The Kodiak is the largest bear in the tundra. It is usually a brown color. Brown bears aren't as fierce as their reputation makes them out to be. Actually, brown bears seldomly eat meat.

Wolves are the better predators of the tundra. They travel in small families and attack caribou and other large herbivores that are too slow to stay with the pack. Some wolves change to a bright white color in the winter.

Wolverines have a reputation of being ferocious and strong. They look like small bears, but they pack a mean punch. Wolverines feed on dead carcasses, but sometimes kill their own prey. Otters and minks are in the same family as wolverines. Otters live near rivers and lakes so they can feed on fish.

Even bats are found in the tundra during the summer! They feed on the swarms of insects that fill the air.
