Lake Mead water levels continuing to drop
April 19, 2015 07:45 AM - Kirk Siegler/NPR

The historic four-year drought in California has been grabbing the headlines lately, but there's a much bigger problem facing the West: the now 14-year drought gripping the Colorado River basin.

One of the most stunning places to see its impact is at the nation's largest reservoir, Lake Mead, near Las Vegas. At about 40 percent of capacity, it's the lowest it's been since it was built in the 1930s.

Study shows how climate affects biodiversity

A key question in the climate debate is how the occurrence and distribution of species is affected by climate change. But without information about natural variation in species abundance it is hard to answer. In a major study, published today in the leading scientific journal Current Biology, researchers can now for the first time give us a detailed picture of natural variation.

Warmer Waters Threaten Future of Traditional Fish and Chips

Popular North Sea fish such as haddock, plaice and lemon sole could be replaced on the menus of the nation’s fish and chip shops as the seas around the UK continue to warm at a rapid rate, a new study warns. Fish distributions are limited by water temperature and some species can only thrive in certain habitats and depths. 

Early warning system to detect algal blooms being launched by EPA
April 7, 2015 03:24 PM - US EPA Newsroom

The U.S. Environmental Protection Agency (EPA) announced today that it is developing an early warning indicator system using historical and current satellite data to detect algal blooms. EPA researchers will develop a mobile app to inform water quality managers of changes in water quality using satellite data on cyanobacteria algal blooms from three partnering agencies-- NASA, NOAA, and the U.S. Geological Survey. 

The multi-agency project will create a reliable, standard method for identifying cyanobacteria blooms in U.S. freshwater lakes and reservoirs using ocean color satellite data. Several satellite data sets will be evaluated against environmental data collected from these water bodies, which allows for more frequent observations over broader areas than can be achieved by taking traditional water samples.
 

Shifting temperatures will affect flavors, quality of food
March 27, 2015 10:34 AM - S.E. Smith, Care2

Love scrumptious vegan pizza? You’d better enjoy it while you can, because climate change is moving in to hog a slice. According to an Australian report, Appetite for Change, climate change isn’t just going to decimate existing crops — it’s also going to change the way the survivors taste. And not in a good way. The researchers say that we’re going to be eating increasingly bland, tasteless, mushy food because of the way shifting temperatures are affecting farming, and in fact, it’s already started happening.

Which diet has the smallest carbon footprint?

The health benefits of the Mediterranean diet are well-known. As well as being healthier, a recent article concludes that the menu traditionally eaten in Spain leaves less of a carbon footprint than that of the US or the United Kingdom. The consequences of climate change range from species extinction to sea-level increases and the spread of diseases. For this reason, researchers have been struggling for years to alleviate its effects, even limiting the pollution caused by food consumption.

Electric Vehicles are Cool, Literally.
March 19, 2015 02:02 PM - Michigan State University

A study in this week’s Scientific Report by researchers at Michigan State University (MSU) and in China add more fuel to the already hot debate about whether electric vehicles are more environmentally friendly than conventional vehicles by uncovering two hidden benefits.

They show that the cool factor is real – in that electric vehicles emit significantly less heat.  That difference could mitigate the urban heat island effect, the phenomenon that helps turn big cities like Beijing into pressure cookers in warm months.

Wetland restoration can help reduce greenhouse gas emissions
March 10, 2015 03:31 PM - University of Gothenburg

Restoration of wetlands can reduce greenhouse gas emissions. This is shown in a report that has been written in part by researchers from the University of Gothenburg. Former wetlands that have been drained and which are currently used for forestry and agriculture give off 11.4 million tons of carbon dioxide equivalents. That can be compared with Sweden's total emissions of 57.6 million tons (when the land use sector is not included). But in Sweden's report to the Climate Convention, emissions from drained peatland are not visible since they are included with forest growth.

CO2 increase may intensify future droughts in tropics
March 9, 2015 03:37 PM - University of Texas at Austin via EurekAlert!

A new study suggests that increases in atmospheric CO2 could intensify extreme droughts in tropical and subtropical regions -- such as Australia, the southwest and central United States, and southern Amazonia -- at much a faster rate than previously anticipated, explains University of Texas at Austin professor Rong Fu in a commentary in the March 9 edition of Proceedings of the National Academy of Sciences.
