STEM Network Blog Intro

STEM Professionals' Blog


The GLOBE International STEM professionals Network (GISN) Blog is an online collaborative effort where scientists associated with GLOBE post their thoughts, comments, and philosophies about a variety of science topics.

GLOBE strongly encourages positive and productive discussions to further advance the scientific understanding of all involved with The GLOBE Program.

This post is the second in a series called “Trees in Trouble”.  To see the first post in this series click here. Climate impacts so many things on this planet, most notably the types of flora and fauna that live in a specific region.  And for those creatures that have annual cycles tied to the local climate, such as the hibernation of bears, migration of birds, and life cycles of insects, a change in climate can shift their way of life and even have subsequent consequences on the environment they live in. Take the pine beetle (Dendroctonus ponderosae) for example.  In...

Many of the world’s glaciers, such as the Exit Glacier in Alaska, United States and Pasterze Glacier in Austria, have lost mass due to melting over the past few years. One such glacier, Exploradores in southern Chile, is also disappearing.  This glacier is a sight to behold – a 20 kilometer frozen mass that is filled with cliffs of luminescent blue and indigo ice. A view from inside the Exploradores Glacier, from Nature A view from inside the Exploradores Glacier, from Nature The Exploradores Glacier is one of many glaciers in the Patagonian Ice Fields located in the...

Since the end of January 2012, Europe has been experiencing record-breaking cold temperatures and heavy snowfalls.  Temperatures are dropping to -40°C (-40°F) and below in Europe.  The canals of Venice are freezing over (the first time since 1991) and sections of the Black Sea have frozen (the first time since 1977).  And, Rome has received its first substantial snowfall since 1986.

Communities in the Sahel region of Africa depend on trees for firewood, food, building materials, and even medicine.  Anecdotal observations in this savannah climate, a transition region to the south of the Sahara Desert, have suggested the number of trees is decreasing.  A recent study by a group of researchers at the University of California at Berkeley has provided scientific support indicating that trees are indeed dying and the decline is being attributed to climate change.  Scientists looked at aerial photos dating back to 1954, satellite images, climate change...

When you think about farms, you may think of the sounds you hear.  Those sounds may include both natural and manmade sounds, such as the rustling of produce in the wind or machines working the fields.  While these are expected sounds that can indicate farm health, scientists recently have been looking at another natural sound: songbirds. Farmers are becoming more interested in looking at the key connections between ecological, economic, and social components to managing their farms, according to Quest science blog.  It is then important to make sure that clear and easy to...
