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.

Most trees obtain water through their massive root systems, but did you know that some trees can absorb water through their leaves as well? This ability is called foliar uptake. Scientists recently discovered that trees in cloud forests use foliar uptake to obtain water. A cloud forest is a forest that has persistent or seasonally persistent fog or low-level cloud cover. Cloud forests are usually in the tropics or subtropics, have evergreen trees (trees that don’t lose their leaves) and tend to have a lot of mosses and vegetation in the understory of the trees. Cloud Forest...


Posted in: GLOBE Science Topics: Earth System Science Investigation Areas: Earth As a System Biosphere

GLOBE’s Earth as a System investigation area cultivates students’ awareness of an intricate web of global connections. Similar to real world scientists, students explore life science concepts, learning that “ organisms can only survive where their needs are met. ”  The Earth as a System investigation area encourages students to observe patterns and connections, such as through phenology. Phenology is the study of how living organisms respond to seasonal changes in their environment. Only through observing and measuring can we notice if changes are occurring and how they occur. ...

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...

Storm Coming Across US If you live in the United States, you probably have heard of the snow storm crossing the country right now. There will be mountain snow in the Rockie Mountains, a potential for a blizzard from Nebraska to Wisconsin and then some snow to the Great Lakes states. The National Weather Service (NWS) definition of a blizzard is: "A blizzard means that the following conditions are expected to prevail for a period of 3 hours or longer: Sustained wind or frequent gusts to 35 miles an hour or greater; and Considerable falling and/or...
