A University of Connecticut climate scientist has confirmed that more intense and more frequent severe rainstorms will likely continue as temperatures rise due to global warming, despite some observations that seem to suggest otherwise.

In a research paper appearing this week in Nature Climate Change, UConn civil and environmental engineering professor Guiling Wang explains that data showing the intensity of severe rainstorms declining after temperatures reach a certain threshold are merely a reflection of climate variability. It is not proof that there is a fixed upper temperature limit for future increases in severe rains, after which they would begin to drop off.

As the city of Chicago has grown in population and industry since it was established more than 180 years ago, so has its need for clean water. Meeting that growing need has presented many challenges. Today, the Chicago Area Waterway System is a complicated network of modified rivers and canals which are used for navigation and shipping, residential and industrial wastewater management, recreation, and aesthetics.

Professor Andrew Johnson and Dr Monika Jürgens, Environmental Scientists at the Centre for Ecology & Hydrology, contributed to a recent study looking at which metal presents the greatest risk to the freshwater ecosystem in the Bohai region of China. They explain more:

Thanks to support from the Natural Environment Research Council Newton Fund, the Centre for Ecology & Hydrology (CEH) has been collaborating with the Research Center for Eco-Environmental Sciences, in Beijing, China since the beginning of 2016 on the topic of chemical pollution in China.

According to 33 years of remote sensing data, productivity of U.S. grasslands is more sensitive to dryness of the atmosphere than precipitation, important information for understanding how ecosystems will respond to climate change.

A new study showing dryness of the atmosphere affects U.S. grassland productivity more than rainfall could have important implications for predicting how plants will respond to warming climate conditions.

Tests of 75 private drinking water wells in Lycoming County, in north-central Pennsylvania, found water from most of the sampled wells contained concentrations of radon that exceeded a proposed, nonbinding health standard for drinking water. Smaller percentages of the wells contained concentrations of arsenic or methane that exceed existing drinking water standards.
