Populations in these countries […]
First study to quantify economic trade-offs of shifting from conventional to shade-grown coffee production. Model suggests farmers can optimize coffee profits by converting one to two-thirds of their acreage to shade-grown.
Researchers create first model for hurricane hazard assessment that is both open source and capable of accounting for climate change. Climate scientists at Columbia University have developed a new, global hurricane model for estimating the long-term hazard of rare, high impact storms under different climate scenarios. The model uses a novel approach to efficiently simulate […]
In the March issue of Nature Climate Change, IRI Director Lisa Goddard explains what may be behind the recent slowdown in global temperature growth in a piece titled “Heat Hide and Seek”.
