This week we have a guest blogger, Dr. Dixon Butler. Dr. Butler was the GLOBE Chief Scientist from 1996-2003 and now works as a consultant to NASA. Students working on GLOBE Hydrology Protocols The general explanation of the scientific method focuses on comparing two situations that differ in only one clearly defined way. One case serves as the control while the other is the experiment. The results must be replicable as a check that the measurements were made correctly and that any other differences between the control and experiment are insignificant. This is an ideal, but it is...

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...

If you’ve seen the science news headlines in the past few weeks, you may have noticed stories summarizing how 2011 ranked in climate history.  What is interesting is that the headlines have been a bit contradictory.  For example, if you’ve read the story as reported by the National Aeronautics and Space Administration (NASA), the headline reads “NASA finds 2011 ninth-warmest year on record”, which to me implies it was another record hot year given that it made the top ten list.  Nonetheless, another story reported in ABS news touts that the world wasn’t quite as...

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 gives the city a...

Last week’s GLOBE Scientists’ blog, “Peculiar weather – just because it sounds odd doesn’t mean it didn’t happen!” talked about inquiry-based learning.  If you have a great question and decide to investigate further, how can you share your results?  Sharing results is an essential part of the scientific method.   If scientists didn’t share their work, how would we know what has already been done?  Or what is already known?  One of the best options for young scientists to share results is to participate in a science fair.  Science fairs often occur in the...

I have always been passionate about the weather.  When I realized that to fulfill this passion I had to have a career in atmospheric science, I started acquiring all sorts of books, charts, movies, and other weather related things.  One of those books was a book from the early 1990’s called It’s Raining Frogs and Fishes by Jerry Dennis.  It was really interesting to me because it discussed all of the different seasons and some different phenomena that different parts of the world experience during the seasons.  As I continue to blog for The GLOBE Program, my mind keeps...

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...

Nitrogen is an important molecule that makes up nearly 78 percent of the atmosphere.  Burning fossil fuels and using fertilizers for agriculture are two ways that this number can increase.  But the atmosphere isn’t the only place that nitrogen is found – it is also found in bodies of water.  Of the nitrogen that is spread in fertilizers, only 25-30 percent is absorbed by plants, so that leaves a lot of nitrogen left to either be absorbed by the atmosphere or into water.  Figure 1 shows the intricacies of the nitrogen cycle, from Physical Geography.net’s Fundamentals...

This week, we have a guest post from Dr. Angela Rowe – a post-doc with Colorado State University and the country of Taiwan examining radar data and monsoons.  Dr. Rowe received her undergraduate degree in meteorology from Millersville University, and her Master’s and Doctoral degrees from Colorado State University, focusing on the Asian and North American Monsoons.  This post is timely, as the monsoon was mentioned in many of the state of the climate of 2010 discussions for different GLOBE regions. When most people hear the word “monsoon”, thoughts of abrupt, intense rainfall...
