New research shows that climate change is exacerbating salmon declines in the Arctic, but warming waters could give another fish species a temporary boost. 

Antarctic ice is melting at a startling pace, and the West Antarctic Ice Sheet is one of the greatest sources of uncertainty in climate projections. Researchers thought westerly winds were accelerating ice loss, but a new study flips the narrative by 90 degrees, pointing instead to winds from the north.

The Time2Graze project will develop and equip farmers in Latin America with tools that assess pasture availability to identify the optimal time to graze livestock 

Supported by the Global Methane Hub, the Time2Graze project is co-led by the World Resources Institute (WRI), the Alliance Bioversity International and Center for Tropical Agriculture (CIAT), the National Agriculture Research Institute of Uruguay (INIA) and WWF. 

While the initial focus for the Alliance is on Colombia and Brazil, the project aims to progressively expand its reach across tropical Latin America and the Caribbean. 

Climate change has already contributed substantially to the global burden of dengue fever, a new study finds. Over 260 million people live in places where dengue incidence is expected to more than double due to climate change by mid-century. The findings could help with public health planning and developing ways to mitigate such risks.

A study in Forest Ecosystems reveals that two closely related evergreen oaks (Quercus aquifolioides and Quercus spinosa) in the Himalayan-Hengduan Mountains adapt to different climates through adjustments in leaf trait integration and modularity, with the high-altitude species having flexible traits for harsh conditions and the lowland one showing tightly coordinated traits for efficiency. It also notes the findings’ value for conservation and understanding species’ responses to climate change.
