A new study of long-term snow monitoring sites in the western United States found declines in snowpack at more than 90 percent of those sites – and one-third of the declines were deemed significant.

Infrared imagery provides valuable temperature data in storms, and when NASA’s Aqua satellite flew over newly developed Tropical Cyclone 11S in the Southern Indian Ocean, its gathered that data allowing forecasters to see where the strongest storms were located within.

Spring is arriving earlier, but how much earlier? The answer depends on where on Earth you find yourself, according to a study led by the University of California, Davis.

As ice the melts, the organic carbon found in permafrost is being released once again after ages of confinement in the soil. It is making its way into Arctic and subarctic lakes and ponds, and modifying their composition. The portrait presented by an international team of researchers that includes Professor Isabelle Laurion of INRS shows the influence that thawing permafrost has on surface water biogeochemistry. Published in Limnology and Oceanography Letters, the results demonstrate that organic carbon from permafrost is making its way into the waters of these regions. This type of carbon is particularly good at absorbing sunlight. As a result, these water bodies are getting increasingly darker and stratified, which affects a number of biological processes in these ecosystems.

For the past 40 years, the total number of Adélie Penguins, one of the most common on the Antarctic Peninsula, has been steadily declining—or so biologists have thought. A new study led by researchers from the Woods Hole Oceanographic Institution (WHOI), however, is providing new insights on of this species of penguin.

Backed by the iconic Table Mountain, Cape Town, South Africa’s second-largest metropolis, seduces increasing numbers of international travelers. Its charismatic neighborhoods, bright beaches, and breathtaking natural landscapes garner shelves-full of tourism awards and terabytes of glowing Instagram posts.

Recently, Cape Town also has become infamous as the home of “Day Zero,” the day when most of the city’s taps are predicted to run dry. With its major, rain-fed supply dams dangerously low after three years of drought, most of the city’s 4 million-plus residents — some rich, many desperately poor — have been facing the prospect of lining up at emergency water distribution points to collect a daily ration of just 6.6 gallons per person sometime before June or July. That’s when winter rains normally begin filling the reservoirs of this Southern Hemisphere city.

Melting icecaps, mass flooding, megadroughts and erratic weather are no laughing matter. However, a new study shows that humor can be an effective means to inspire young people to pursue climate change activism. At the same time, fear proves to be an equally effective motivator and has the added advantage of increasing people’s awareness of climate change’s risks.

Data centres and smartphones will be the most damaging information and communications technologies to the environment by 2040, according to new research from W Booth School's Lotfi Belkhir.

Large day-to-day swings in temperature were associated with significantly more heart attacks in a study being presented at the American College of Cardiology’s 67th Annual Scientific Session. Given that some climate models link extreme weather events with global warming, the new findings suggest climate change could, in turn, lead to an uptick in the occurrence of heart attacks, researchers said.

Native wildflowers were surprisingly resilient during California’s most recent drought, even more so than exotic grasses. But signs of their resilience were not evident with showy blooms aboveground. Rather, they were found mostly underground, hidden in the seed bank, according to a study from the University of California, Davis.
