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. Figure 1:...

Blog originally posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/30/an-interesting-relationship-soil-temperature-and-climate-change/ It seems common place that warmer air temperature leads to warmer soil temperature. And while this relationship seems intuitive, the effect isn’t always studied, especially with respect to the response from microorganisms. That is why researchers are investigating what happens when the soil temperature increases. An intricate network of soil microorganisms From: Commonwealth Scientific and Industrial Research...

Blog originally posted on the GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/23/trees-in-trouble-what-affect-does-tree-mortality-have-on-climate-change/ Through our trees in trouble series, we’ve examined trees in the Sahel zone in Africa and the United States.  This problem, climate change and dying trees, has been seen on every continent, the only exception being Antarctica, due to the lack of vegetation on the frozen continent.  Scientists have recently found that there is an alarming loss rate of big, old trees, whose ages range from 100-300+ years, in...

Blog previously posted on The GLOBE Scientists' Blog: http://blog.globe.gov/sciblog/2013/01/16/a-tale-of-two-extremes/ Weather extremes have become a common theme in the news headlines the past few weeks. For example, nearly every part of the United States has been experiencing one of two extremes – either frigid cold or record-breaking high temperatures. Places like Arizona and California experienced below-freezing temperatures, which can have potential impacts on the crops grown in these typically balmy regions. In contrast, cities in the Southeast U.S., such as Atlanta, Georgia,...
