Climate modelling that best accounts for the processes that sustain plant life predicts plants could absorb up to 20% more CO₂ than the simplest version predicted.

New findings from the La Brea Tar Pits in southern California suggest human-caused wildfires in the region, along with a warming climate, led to the loss of most of the area’s large mammals.

North America’s boreal forests have been burning a lot, probably more and more over the past 60 years. Yet the long-term trend indicates that they are burning less than they were 150 years ago.
Wetlands can help limit the spread of the voracious round goby, an invasive species that has infiltrated the Great Lakes and has become widespread in the St. Lawrence River.
Extreme heat waves are putting lives in danger, with some of the hottest urban neighborhoods 10 degrees hotter or more than their wealthier neighbors. Often, these are communities of color.
Many plants are really good at withstanding bushfires, but the combination of drought, heatwaves and pest insects under climate change may push them to the brink.
New research shows nature started its long road to recovery in 2020 – especially in NSW and Victoria. But overall conditions across large swathes of the country remain poor.
Greening cities have a huge impact. The trees go beyond just lowering temperatures. They help decrease the demand for indoor cooling like air-conditioners saving money.
Extreme weather will affect people and animals, as well as whole ecosystems. Research using satellites shows that ecosystems worldwide are vulnerable to collapse.
Constant, complex changes in cities and mine sites are hard to monitor. Drawing on digital aerial photography, it’s now possible to track land-use and vegetation changes in areas as small as 10-20cm.
