Globalization has accelerated the spread of mosquito species that transmit human diseases. An analysis in Nature Communications shows that 45 disease-vector mosquito species have been introduced to non-native regions worldwide. go.nature.com/4hn6ogW 🧪
This is figure 5, which shows global hotspots and coldspots of non-native mosquito introduction and establishment, and their socio-economic and environmental drivers.

Mortality from fire & wind is increasing in Europe's forests, but what about biotic disturbances? A new, massive dataset compiled by @thlasny.bsky.social and many local experts shows a mixed picture: While wood borers increase strongly, defoliator activity generally decreases doi.org/10.1111/gcb....

Plants cool the land through evapotranspiration, but green foliage can absorb more heat than lighter surfaces, causing warming. A study finds that in the northern hemisphere, cooling outweighs warming until the end of the growing season. In PNAS: www.pnas.org/doi/10.1073/...
