A “sleeping giant” hidden in permafrost soils in Canada and other northern regions worldwide will have important consequences for global warming, says a new report led by University of Guelph scientist Merritt Turetsky. Scientists have long studied how gradual permafrost thaw occurring over decades in centimetres of surface soils will influence carbon release to the atmosphere. But Turetsky and

An international team of scientists has found part of the world’s largest ice shelf is melting 10 times faster than expected due to solar heating of the surrounding ocean. In a study of Antarctica’s Ross Ice Shelf, which covers an area roughly the size of France, the scientists spent several years building up a record

The idea of the heat island—that densely built-up urban areas are considerably hotter than the rural and semi-rural landscapes that surround them—has been extensively studied and is widely accepted by academics and the public. But a new study by a Concordia researcher takes a closer look at the phenomenon and what can be done to

There are two primary causes of global mean sea level rise – added water from melting ice sheets and glaciers, and the expansion of sea water as it warms. The melting of Antarctica’s ice sheet is currently responsible for 20-25% of global sea level rise. But how much of a role will it play hundreds

Extreme ocean winds and wave heights are increasing around the globe, with the largest rise occurring in the Southern Ocean, University of Melbourne research shows. Researchers Ian Young and Agustinus Ribal, from the University’s Department of Infrastructure Engineering, analysed wind speed and wave height measurements taken from 31 different satellites between 1985-2018, consisting of approximately

Canada’s oil sands CO2 emissions are significantly higher than indicated by industry data collected using internationally recommended methods, according to a study published Tuesday. Environment Canada scientists flying over the region took atmospheric measurements and found CO2 emission intensities up to 123 percent higher than current estimates. Their findings were published in the journal Nature Communications. “This leads

Climate change and ocean warming threaten coral reefs and disrupt the harmonious relationship between corals and their symbiotic algae, a process known as “coral bleaching.” However, a new study conducted by scientists at the University of Hawai’i (UH) at Mānoa and the California Academy of Sciences revealed soft tissues that cover the rocky coral skeleton

A new Stanford University study shows global warming has increased economic inequality since the 1960s. Temperature changes caused by growing concentrations of greenhouse gases in Earth’s atmosphere have enriched cool countries like Norway and Sweden, while dragging down economic growth in warm countries such as India and Nigeria. “Our results show that most of the

A transition from coal-based energy to cleaner-burning gas has long been viewed as a staple of many climate action plans, despite concerns over leakage and possible harmful emissions. A recent study published in the journal Nature Climate Changefinds that not only is such a shift central to meeting climate targets and stabilizing global temperature rise, but

There have been five mass extinctions in the history of the Earth. But in the 21st century, scientists now estimate that society must urgently come to grips this coming decade to stop the very first human-made biodiversity catastrophe. “The sixth extinction is on our societyʻs shoulders; it really is,” said ecologist Greg Asner, who serves
