A new study published in Nature Climate Change provides one of the most comprehensive assessments yet of how humanity is being impacted by the simultaneous occurrence of multiple climate hazards strengthened by increasing greenhouse gas emissions. This research reveals that society faces a much larger threat from climate change than previous studies have suggested.
Current climate models do not include the effects on the global climate of melting ice from Antarctica. The new research is the first to project how the melting of the Antarctic ice sheet will affect future climate. The researchers found that the entire Earth will continue warming, but the atmosphere will warm more slowly because more of the heat will be trapped in the ocean.
Caught in the act of landfall, Tropical Cyclone Gaja was seen by NASA's Aqua satellite as it passed overhead and collected temperature information.
The Bureau of Reclamation has released a report that identifies innovative approaches to improve drought resiliency within the Washita Basin in Oklahoma. It specifically looked at Foss and Fort Cobb Reservoirs. The study showed that a repeat of paleo droughts could have far greater impacts on reservoir yield than the observed drought of record. The study also quantified the risks of a reservoir not fulfilling its intended purposes under different drought scenarios.
The discovery addresses two challenges prevalent in the developing world: sanitation and growing energy needs. The researchers said the reaction that creates the hydrochar sterilizes the waste material, so it becomes safe to handle. The 'coals' can potentially be utilized for household heating and cooking, while the liquid byproduct (the aqueous phase) could be used as fertilizer.
Christopher A. Williams, associate professor in Clark University's Graduate School of Geography and postdoctoral research scientist Huan Gu, Ph.D., worked with The Nature Conservancy and close to two dozen institutional partners on 'Natural Climate Solutions for the United States,' published today in Science Advances. The new study highlights natural solutions in the United States that offer the most promise to help limit warming to 1.5 degrees Centigrade (approximately 3 degrees Fahrenheit).
Tropical Cyclone Gaja continued to track toward a landfall in southeastern India when NASA-NOAA's Suomi NPP satellite flew over the Bay of Bengal and provided a visible image of the storm.
East Africa is one of the most vulnerable regions in the world to extreme weather and climate events. This new research improves ability to accurately assess the development and impact of climate change. An analysis of several sources in the region identified the most suitable sources of high-quality climate and hydrological data. The data can be used to identify hot spots and plan adaptation and mitigation measures at previously impossible finer spatial scale.
New supercomputer simulations by climate scientists at Lawrence Berkeley National Laboratory have shown that climate change intensified the amount of rainfall in recent hurricanes such as Katrina, Irma, and Maria by 5 to 10 percent. They further found that if those hurricanes were to occur in a future world that is warmer than present, those storms would have even more rainfall and stronger winds.
A new study found that 21 percentof the United States' greenhouse gas pollution (1.2 Pg CO2e year) could be removed through enhanced management of forest, grassland, agricultural, and coastal areas. An offset at this level would be the equivalent to pollution from every single US car and truck on the road.
