If greenhouse gas emissions continue at the current level, the average temperature will tend to rise by as much as 4 °C in some regions. Under this scenario, extreme weather events will be more intense and frequent, according to projections made using the IPCC’s new climate models.

A model of the eastern California forests of the Sierra Nevada looks at the longer-term future of wildfires under future climate change scenarios. Results show an initial roughly decade-long burst of wildfire activity, followed by recurring fires of decreasing area — a pattern that could apply to other hot, dry forests in the West.

Ground breaking research by Lancaster University has found ‘elevated’ levels of toxic chemicals involved in the manufacture of items from stain-proof school uniforms to non-stick pans, in the remote Arctic.

Researchers from an interdisciplinary team of several sections from the GFZ German Research Centre for Geosciences, together with colleagues from Hannover, Kiel and Padua, have for the first time demonstrated a direct link between the decrease in the Dead Sea's water table, evaporation and land subsidence. They report on this in the journal Scientific Reports.

Twenty months after declaring a climate emergency and establishing a set of vital signs for the Earth, a coalition headed by two Oregon State University researchers says the updated vital signs “largely reflect the consequences of unrelenting business as usual.”

In a year marked by unprecedented flooding, deadly avalanches, and scorching heat waves and wildfires, the climate emergency's enormous cost--whether measured in lost resources or human lives--is all too apparent. Writing in BioScience, a group led by William J. Ripple and Christopher Wolf, both with Oregon State University, update their striking 2019 "World Scientists' Warning of a Climate Emergency" with new data on the climate's health. The news is not good.

Crested rat fossils suggest that ecological corridors once connected Africa to the Levant, according to a study. Early humans and other hominins dispersed out of Africa through the Levant multiple times, but whether these journeys relied on technology to cross the Saharo-Arabian deserts or followed ecological corridors created by climate change is unclear.
