The world’s second-largest ice sheet, and the single largest contributor to global sea level rise, is potentially becoming unstable because of fractures developing in response to faster ice flow and more meltwater forming on its surface.

Since the saltiness of ocean surface waters is a key variable in the climate system, understanding how this changes is important to understanding climate change. Thanks to ESA’s Climate Change Initiative, scientists now have better insight into sea-surface salinity with the most complete global dataset ever produced from space.

For the first time, scientists have developed a method to monitor carbon emissions from tropical forests with an unprecedented level of detail. 

How did life survive the most severe ice age? A McGill University-led research team has found the first direct evidence that glacial meltwater provided a crucial lifeline to eukaryotes during Snowball Earth, when the oceans were cut off from life-giving oxygen, answering a question puzzling scientists for years.

Seismic engineers and psychologists from the University of British Columbia teamed up with a visual artist to create the image above, which shows what a Vancouver elementary school would look like after a major earthquake. 

Antarctica is the largest reservoir of ice on Earth – but new research by the University of South Australia suggests it could be at greater risk of melting than previously thought.

The U.S. spends $5 billion a year to repair damages to road infrastructure from winter snow and ice control operations and the use of traditional deicers. 

In a new study, researchers provide conclusive evidence of a statistical relationship between the incidence rates of invasive cancer in a given area in the U.S. and the amount of precipitation and climate type (which combines the temperature and moisture level in an area). 

New research reveals how penguins have dealt with more than a century of human impacts in Antarctica and why some species are winners or losers in this rapidly changing ecosystem.

Sometimes, pollution is blatantly obvious: the iridescent slick of an oil spill, goopy algae washing up on a beach or black smoke belching from a smokestack.
