Europe's abandoned farmlands could find new life through rewilding, a movement to restore ravaged landscapes to their wilderness before human intervention. A quarter of the European continent, 117 million hectares, is primed with rewilding opportunities, researchers report.

Unprecedented wildfires in Canada and parts of Amazonia last year were at least three times more likely due to climate change and contributed to high levels of CO2 emissions from burning globally, according to the a new systematic review. The State of Wildfires report takes stock of extreme wildfires of the 2023-2024 fire season (March 2023-February 2024), explains their causes, and assesses whether events could have been predicted. It also evaluates how the risk of similar events will change in future under different climate change scenarios.

A recent study details how trees in New York City and Boston are more negatively impacted by heat waves and drought than trees of the same species in nearby rural forests. The finding highlights the challenges urban trees face in the context of climate change and underscores the importance of tailored urban forestry management as a tool for protecting tree species and reducing urban heat islands.

Planet-warming greenhouse gas emissions associated with the global food supply chains induced by diets could fall by 17% if people change their food choices towards more plant-based diets.

Researchers show that the adaptation of antlions to their ecological niche has also changed their venom. They compared the venom system of antlion and closely related green lacewing larvae. Antlions produce a much more complex venom from three different venom glands than lacewing larvae do. All the venom proteins identified come from the insects themselves, not from symbiotic bacteria. Some of the toxins are new and appear to be unique to antlions. Waiting for their victims in pitfall traps in the sand, antlions can use their venom to immobilize larger prey. The venom therefore plays an important ecological role in adapting to their barren habitat.
