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...

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...

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...

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...

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...

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...

In December 2009, Dr. Donna Charlevoix, of the GLOBE Program Office, attended the COP-15 (15th meeting of the Conference of Parties) meeting in Copenhagen, Denmark.  Dr. Charlevoix gave a great summary of the meetings in five separate blog posts that began on 7 December 2009.  Some of you may have read these posts, and for those of you who haven’t, I encourage you to visit them, beginning with the first to get a better understanding of the importance of these annual meetings. This year’s meeting was titled COP-17 (17th Conference of Parties).  The meeting is...

Sometimes in a rapidly changing world, it is difficult to see the effects that small changes in human lifestyle can have on not only climate, but on ecosystems.  Various countries and international organizations are working to pass legislation to ensure change.  One such case of legislation working is being observed in the San Francisco Bay – the return of harbor porpoises.  This was recently reported in the  QUEST biology blog . The map below shows the location of the San Francisco Bay, marked by the bubble with an A, from Google.  In 1972,...
