Groundwater recharge in the American west under climate change

Groundwater recharge in the Western U.S. will change as the climate warms–the dry southern regions will have less and the northern regions will have more, according to new research.

New Antarctic heat map reveals sub-ice hotspots

An international team of scientists, led by British Antarctic Survey (BAS), has produced a new map showing how much heat from the Earth’s interior is reaching the base of the Antarctic Ice Sheet.

Rising sea levels could weaken coral reefs’ protective influence on Brazil’s coast

Rising sea levels could diminish the ability of Brazil’s coral reef systems to weaken incoming ocean waves, resulting in stronger waves hitting populated areas on the Brazilian coastline, according to new research.

Study: Major return on investment from improving climate observations

A well-designed climate observing system could help scientists answer knotty questions about climate while delivering trillions of dollars in benefits by providing decision makers information they need to protect public health and the economy in the coming decades, according to a new study published today.

Scientists may have solved mystery of rapidly rising Indian Ocean sea level

Sea levels around the world have risen by 1.7 millimeters (0.07 inches) on average each year since 1880, but in recent years, scientists have observed a rapid increase in sea level in the north Indian Ocean. Tide gauge records and other datasets reveal the pace of sea level rise in the north Indian Ocean has accelerated to 3.1 millimeters (0.12 inches) per year within the last three decades. The accelerating sea level rise has confounded scientists but new research claims weakening of South Asian monsoons may be to blame.

New approach to geoengineering simulations is significant step forward

Using a sophisticated computer model, scientists have demonstrated for the first time that a new research approach to geoengineering could potentially be used to limit Earth’s warming to a specific target while reducing some of the risks and concerns identified in past studies, including uneven cooling of the globe.

Melbourne and Sydney should prepare for 50-degree Celsius days

A new study warns that Melbourne and Sydney should prepare for 50-degree Celsius (122-degree Fahrenheit) summer days under the Paris Agreement global warming limit of 2 degrees Celsius (4 degrees Fahrenheit). The new study assessed the potential magnitude of future extreme temperatures in Australia under Paris targets of an increase in global temperatures of 1.5 and 2 degrees Celsius (3 and 4 degrees Fahrenheit) above pre-industrial levels.

Warming climate could increase bacterial impacts on Chesapeake Bay shellfish, recreation

Researchers have found that three common species of Vibrio bacteria in the Chesapeake Bay could increase with changing climate conditions by the end of this century, resulting in significant economic and healthcare costs from illnesses caused by exposure to contaminated water and consumption of contaminated shellfish.

Increases in wildfire-caused erosion could impact water supply and quality in the West

A growing number of wildfire-burned areas throughout the western United States are expected to increase soil erosion rates within watersheds, causing more sediment to be present in downstream rivers and reservoirs, according to a new study.

Heat stress escalates in cities under global warming

Heatwaves are intensifying in cities due to the double whammy of the urban heat island effect and global warming, according to a new study. By the middle of this century, Belgian cities may experience more than 17 heat wave days per year, on average, with an even greater intensity of 4 degrees Celsius (7.2 degrees Fahrenheit) excess warming.
