A couple of years ago, I attended a seminar sponsored by the Climate and Global Dynamics Division (CGD) of the National Center for Atmospheric Research (NCAR) on how climate change is threatening the survival of wolverines (Gulo gulo). This scientist, Synte Peacock from CGD, painted a gloomy outlook for this ferocious creature after using a climate model to examine changes in spring snow cover and summer air temperatures. However, recent legislative proposals may make the future a little brighter.

This week we have a guest blogger, Jennifer Bourgeault. Jennifer, a member of the GLOBE Land Cover/Biology Team for 10 years, is the North Country Education Services (NCES) New Hampshire GLOBE Partnership coordinator and Master Trainer in the Land Cover/Biology protocols. She thinks everyone should know how to use the Modified UNESCO Classification (MUC) Field Guide to classify land cover and how to use Multispec to look at change over time.

Earth Day has been inspiring demonstrations and projects for a healthier, more sustainable environment for more than 40 years. The first Earth Day, celebrated on 22 April 1970, featured over 20 million Americans joining together in auditoriums, parks and streets across the country to show solidarity in the fight against oil spills and toxic dumping, protecting wildlife and their habitats, and carbon...
The cold weather this last month has led to Lake Erie developing ice cover. This past week, the temperature has been averaging about 20 F (-6 C). Even with temperatures in the 50s and 60s F (10 C to 15 C), ice has formed. See the Figure 1 below.
As you can see in the picture, the ice on Lake Erie is broken up into things that look like islands. The wind blows the ice around and breaks it up. There is a straight line through Lake St. Clair that extends down into Lake Erie. What do you think caused this straight line? Usually, on Earth, straight lines are produced by humans.
