Freely Available Risk Model for Hurricanes, Tropical Cyclones

As human-driven climate change amplifies natural disasters, hurricanes and typhoons stand to increase in intensity. Until now, there existed very few freely available computer models designed to estimate the economic costs of such events, but a team of researchers has recently announced the ...

New Research Finds That More Than 90% of Global Aquaculture Faces Substantial Risk from Environmental Change

Many of the world's largest aquatic food producers are highly vulnerable to human-induced environmental change, with some of the highest-risk countries in Asia, Latin America and Africa demonstrating the lowest capacity for adaptation, a landmark ...

Study of Earth's Stratosphere Reduces Uncertainty in Future Climate Change

New research reduces uncertainty in future climate change linked to the stratosphere, with important implications for life on Earth. A significant source of uncertainty relates to future changes to water vapor in the stratosphere, an extremely dry region of the atmosphere 15--50 km above the ...
