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...

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...

A few weeks ago, the British Broadcasting Company (BBC) wrote about a report claiming that some of the fruit from native trees in Britain are ripening anywhere from 13 to 18 days earlier than they did a decade ago.  The report was from Nature’s Calendar, a data collection network in the United Kingdom.  While the cause isn’t specifically known, many believe it’s due to a change in climate. What does a change like this mean to the earth as a system? Scientists are interested in studying the connections between the different Earth processes – from how greenhouse gases are...

This week we’ll finish our look at the climate summaries for each GLOBE region with a focus on the Near East-North Africa region.  Remember that these annual reports provide a summary of the global climatic conditions and are a great benchmark for monitoring climate. Regional reports provide a tremendous amount of information. The temperature and precipitation climate summaries are highlighted here, but if you are interested, more information about the Near East-North Africa region state of the climate is available from this website:...
