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.




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...

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...

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,...

In the article in Nature Geoscience , it explained that such droughts can further enhance global warming. When a drought occurs, the plants wither and die and no longer uptake carbon dioxide (normally living plants serve as a...

Blog originally posted on The GLOBE Scientists' Blog:  http://blog.globe.gov/sciblog/2012/11/14/esno-basics-what-is-it/ Through many posts here on the Scientists’ Blog, we, in one way or another, discuss ENSO.  ENSO, or El Niño-Southern Oscillation, is a quasi-periodic climate pattern that occurs in the tropical Pacific Ocean.  When the conditions change, the atmosphere responds in many different ways.  In certain locations, it is cloudier and it rains more, while in others it’s clear and dry.  Through our “ENSO Basics” series, we’ll take a look at ENSO in...
