It’s a tempting thought: With climate change so difficult to manage and nations unwilling to take decisive action, what if we could mitigate its effects by setting up a kind of chemical umbrella—a layer of sulfuric acid in the upper atmosphere that could reflect the sun’s radiation and cool the Earth?

Like a mirage on the horizon, an innovative process for converting a potent greenhouse gas into a food security solution has been stalled by economic uncertainty.

Global change is eroding life on earth at an unprecedented rate and scale. 

If you think living away from the coast keeps you safe from climate change and rising waters, think again.

After the natural warming that followed the last Ice Age, there were repeated periods when masses of icebergs broke off from Antarctica into the Southern Ocean.

Fly into Orlando, Florida, and you may notice a 22-acre solar power array in the shape of Mickey Mouse’s head in a field just west of Disney World. 

Training AI to detect and identify marine mammal calls from underwater acoustic recordings opens new possibilities for more cost-effective marine mammal research.

Even short-term exposure to air pollution impacts our brain performance and capacity to work, according to researchers from The University of Queensland and Carnegie Mellon University.

The Australian Alps may suffer from a loss of snow and surrounding regions could endure flooding as climate change supercharges phenomena known as ‘atmospheric rivers’.

Understanding how climate change will affect the flooding of rivers may become easier with a new framework for assessing flood risk that's been developed by an interdisciplinary team from Penn State.
