A Florida State University researcher is part of a team that has found varying projections on global warming trends put forth by climate change scientists can be explained by differing models’ predictions regarding ice loss and atmospheric water vapor.

The work will help climate scientists reconcile various models to improve their accuracy, said Florida State University Meteorology Professor Ming Cai, one of the authors of the study published in Nature Communications .
Climate scientists agree that the Earth’s surface temperature is warming, but the details of exactly where and by how much are less clear. A worst-case climate change scenario (known as the “Representative Concentration Pathway 8.5”) predicted a likely increase in average global temperatures of about 2.6 degrees Celsius to 4.8 degrees Celsius (or about 4.7 degrees Fahrenheit to 8.6 degrees Fahrenheit) by 2100.
“This uncertainty limits our ability to foresee the severity of the global warming impacts on

VALENCIA, Spain, Oct. 6, 2020 /PRNewswire/ — Technology will be critical to ensure water supply in emerging countries around the world in the aftermath of the coronavirus pandemic, explained Chema Nebot, Head of Business Development at Spanish Water technology company Idrica.
Nebot, who is one of the leading experts in integral water cycle management technology in Europe, explained that to strengthen the access of the most vulnerable societies to water resources it is going to be necessary and urgent to implement technologies such as digital twin and smart meters in the developing world.
Processes optimisation and automation will boost energy efficiency in the water industry, and countries must bet on the future of the access to water to avoid social conflict.
“The world of tomorrow will rely on good management of water resources across the world. The success of that effort depends largely on the state of
The water crisis in Flint, Michigan, brought much-needed attention to the problem of potentially toxic metals being released from drinking water distribution pipes when water chemistry changes. Now, researchers reporting in ACS’ Environmental Science & Technology have investigated how hexavalent chromium, known as Cr(VI), can form in drinking water when corroded cast iron pipes interact with residual disinfectant. Their findings could suggest new strategies to control Cr(VI) formation in the water supply.

The metal chromium, known as Cr(0), is found in cast iron alloy, which is the most widely used plumbing material in water distribution systems. As pipes corrode, a buildup of deposits, known as scale, forms on the pipes’ inner walls. Trace chemicals in water can react with scale, forming new compounds that could be released into the water. Some of these compounds contain Cr(VI), which, at high doses, can cause lung cancer, liver damage, reproductive issues and developmental
