New online! Elevation-dependent climate change in mountain environments
Elevation-dependent climate change in mountain environments
Nature Reviews Earth & Environment, Published online: 25 November 2025; doi:10.1038/s43017-025-00740-4Environmental changes in mountains often depend on elevation. This Review outlines how past and future temperature, precipitation and snowfall trends vary between mountains and lowlands across various mountain regions and discusses the drivers responsible.

Excellent essay. Should you use AI (as a student, or later) if you could "get away with it"? What might the long-term consequences be, for you - and society?

CO2 was at 330 ppm when I started my PhD in oceanography at MIT in 1974. And yes, at the time, we well knew that CO2 was increasing, that fossil fuels were the main culprit, and that this was not good for the climate. I can't believe that after more than half a century, COP was not able to do more.

As human groups migrated and settled across Holocene Eurasia, dogs often traveled with them and were sometimes traded among populations, researchers report in Science. The results reveal the integral role these animals played in culture and exchange. https://scim.ag/4peI4kl
Genomic evidence for the Holocene codispersal of dogs and humans across Eastern Eurasia
As the first domestic species, dogs likely dispersed with different cultural groups during the Late Pleistocene and Holocene. To test this hypothesis, we analyzed 73 ancient dog genomes, including 17 ...
