Credit: CC0 Public Domain A study examining the urban microclimatic impact of the 2019-20 Australian bushfires has uncovered how they affect local meteorological and air quality. Its findings could help understand the potential consequences of an increased rate and extension of bushfires, and especially regarding improving risk preparedness and coping […]

The concentration of algae in two remote mountain lakes more than doubled in the past 70 years Global warming is turning clear mountain lakes green in the western United States because of an increase in algae blooms “without historical precedent”, researchers reported on Tuesday.

Animation In a study published recently in Ecology and Evolution, an international team of researchers focused on what can happen to ocean ecosystems when fishing pressure increases or decreases, and how this differs between tropical to temperate marine ecosystems. The team, led by Elizabeth Madin, researcher at the Hawai’i Institute of […]

Douglas firs are the most abundant trees in North America. Their ecological niche spans Southern Mexico to the Northern Rockies. Warming Will Reduce Trees’ Ability to Slow Climate Change New research suggests that the most abundant trees in North America absorb less carbon dioxide as the world’s temperature rises. The […]

Beavers Gnawing Away at the Permafrost The large rodents are massively changing landscapes in the Arctic, which could have serious consequences for the frozen soils and our future climate. Alaska’s beavers are profiting from climate change, and spreading rapidly. In just a few years’ time, they have not only expanded […]
