In one of the coldest, driest places on Earth, CU Boulder scientists have developed a possible answer to a longstanding mystery about the chemistry of streamflow, which may have broad implications for watersheds and water quality around the world.

Ancient molecules may show first glimpse of life after Earth's ice-covered history.

The Greenland ice sheet melted a little more easily in the past than it does today because of geological changes, and most of Greenland's ice can be saved from melting if warming is controlled, says a team of Penn State researchers.

A gigantic cavity — two-thirds the area of Manhattan and almost 1,000 feet (300 meters) tall — growing at the bottom of Thwaites Glacier in West Antarctica is one of several disturbing discoveries reported in a new NASA-led study of the disintegrating glacier.

It spawned a cheesy movie and crowds gather for it every year, but Groundhog Day is more about fun than fact, says a University of Alberta expert.

Rising temperatures could make some species sterile and see them succumb to the effects of climate change earlier than currently thought, scientists at the University of Liverpool warn.

Warmer water temperatures, combined with low-level exposure to chemicals already known to be harmful to aquatic life, influence the expression of genes in the offspring of an abundant North American fish species – and threaten organisms whose sex determination is sensitive to water temperature.

Climate change is bad news for coral reefs around the world, with high ocean temperatures causing widespread bleaching events that weaken and kill corals.

A new Tulane University study questions the reliability of how sea-level rise in low-lying coastal areas such as southern Louisiana is measured and suggests that the current method underestimates the severity of the problem. 

An analysis of satellite data has revealed global patterns of extreme rainfall, which could lead to better forecasts and more accurate climate models.
