Air temperatures on Earth have been rising since the Industrial Revolution. While natural variability plays some part, the preponderance of evidence indicates that human activities—particularly emissions of heat-trapping greenhouse gases—are mostly responsible for making our planet warmer.

A new study found that measuring the time it takes for a radar pulse to travel from a satellite to the sea surface and back again can reveal the thickness of river ice and dates when it is safe to travel on ice roads and bridges in arctic regions.

Understanding when and where trees die in vast tropical forests is a challenging first step toward understanding carbon dynamics and climate change.

Many North American migratory birds are shrinking in size as temperatures have warmed over the past 40 years.

Scientists have deployed a network of seismometers onto Antarctica’s Brunt Ice Shelf in an experiment that will test the instrument’s ability to operate on icy moons in the Solar System.

Thawing of permafrost due to climate change could expose the Arctic population to much greater concentrations of the cancer-causing gas Radon, a new story has found.

A century after scientists first noted that the environment contributes to the evolution of adaptive differences among plant populations, scientists are on the verge of figuring out how that adaptation happens — by combining results from huge “common garden” experiments with genomic sequencing.

The presence of pink pumice in the giant pumice raft of the 2012 Havre eruption that drifted across the southwest Pacific Ocean has led researchers to recognise the immense power of underwater volcanic eruptions.

A long-term study in the Southern Ocean reveals a clear correlation between warming waters, decreased sea ice, and reduced abundance of Antarctic silverfish.

Droughts occurring at the same time across different regions of the planet could place an unprecedented strain on the global agricultural system and threaten the water security of millions of people, according to a new study in Nature Climate Change.
