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.




In most scientific research an important test is whether the results of an experiment can be repeated, typically repeated by another lab and research group. A result that cannot be confirmed in this way is generally viewed as invalid. This is a great test for controlled experiments where virtually identical experimental conditions may be achieved. In Earth science research involving observations of the natural world, experimental conditions cannot be reproduced. For environmental research the standard must switch for repeatable to intercomparable – capable of being compared. Research...

In the early 1980’s, I chaired a group of scientists exploring the idea of a comprehensive satellite mission to study all aspects of the global environment. The group was diverse with expertise covering the range of Earth science disciplines from geology, ecology, oceanography, limnology, glaciology, and atmospheric science and their various sub-disciplines.  Their first recommendation was take today’s data today. In all of Earth science there is the recognition that we have only one Earth to study. How Earth works is revealed by watching it change in a comprehensive manner and...

Beste mensen, Het effect van de uitzonderlijk zachte winter op de natuur is ook bij de media niet onopgemerkt gebleven. In de uitzending van het KRO programma Brandpunt op zondag 16 maart komt het onderwerp aan bod. Zie http://gemi.st/KN_1656575 . Het item begint op 23:20. Verder zat ik op zondag 9 maart in het programma Jinek op Zondag. Dit is terug te zien op http://gemi.st/KN_1656819 . Tenslotte zat ik op woensdag 19 maart in het EO-programma 'Melk en Honing'. De uitzending is terug te bekijken op  http://gemi.st/EO_101212300 . Vriendelijke groeten, Arnold

From January 22 to 26, 2012, scientists from around the world gathered for the American Meteorological Society annual meeting, which was held in New Orleans, Louisiana.  Scientists from the GLOBE Program stayed next to the beautiful Mississippi River. The Mississippi River in New Orleans (photo courtesy of Dr. Donna Charlevoix) The Mississippi River is the lifeblood of New Orleans and has so impacted the city that the city was actually developed around it. The first buildings were constructed around the river edge, which has the highest ground, and now...
