Scientists reported new research results today suggesting that artificial objects in orbit around the Earth are brightening night skies on our planet significantly more than previously understood.

During drought, plants use a signalling molecule known from animals to limit their water loss. The molecule provides them with a kind of memory of how dry the day was.

The vast majority of the world’s largest meat and dairy companies have not made an explicit commitment to achieving net-zero emissions by 2050, finds a new analysis by researchers at New York University.

In the last few years, as climate changes continues to become more severe, there has been a growing push for rich countries to pay poorer ones to preserve and protect rain forests and other tropical forests.

In the Arctic, climate change and pollution are the biggest threats to top predators like narwals.

Hail severity may increase in most regions of the world while Australia and Europe are expected to experience more hailstorms as a result of climate change, an international review led by a UNSW Sydney researcher has found.

Arctic habitats have fascinated biologists for centuries. 

A new study suggests that clearing the invasive woody weed Prosopis julifora and grassland restoration in Baringo County, Kenya, may have significant financial benefits for local stakeholders and contribute to climate change mitigation.

Perhaps the best hope for slowing climate change – capturing and storing carbon dioxide emissions underground – has remained elusive due in part to uncertainty about its economic feasibility.

Water scarcity is often understood as a problem for regions experiencing drought, but a new study from Cornell and Tufts universities finds that not only can localized water shortages impact the global economy, but changes in global demand send positive and negative ripple effects to water basins across the globe.
