Groundwater may play an unrecognized role in thawing Arctic permafrost following wildfires, according to new research.

Tuna is one of the most ubiquitous seafoods. It can be eaten from a can or as high-end sashimi and in many forms in between. But some species are over-fished and some fishing methods are unsustainable. How do you know which type of tuna you’re eating?

Some tuna is certified as sustainably caught by groups such as the Marine Stewardship Council (MSC) that set standards for sustainable fishing. But these certifications are only good if they are credible.

Tropical rainforests continue to buffer wildlife from extreme temperatures even after logging, a new study has revealed.

Microseismic signals could aid in imaging subsurface geology

Scientists from Rice University and Texas A&M University-Corpus Christi’s Harte Research Institute for Gulf of Mexico Studies have discovered that Earth’s sea level did not rise steadily but rather in sharp, punctuated bursts when the planet’s glaciers melted during the period of global warming at the close of the last ice age. The researchers found fossil evidence in drowned reefs offshore Texas that showed sea level rose in several bursts ranging in length from a few decades to one century.

Why did the Jakobshavn Isbræ ice stream in West Greenland retreat under a cold climate period called the Younger Dryas?

The JRC’s annual forest fires report confirms a trend towards longer and more intense fire seasons in Europe and neighbouring regions, with wildfires now occurring throughout the year. The report coincides with an international study which finds that global wildfire trends could have significant health implications due to rising harmful emissions.

Planting trees, restoring peatlands, and better land management could provide 37 percent of the greenhouse gas mitigation needed between now and 2030 to keep global warming to 2 degrees Celsius, according to a new study published in the Proceedings for the National Academy of Sciences.

The boreal forest is essential to Canada and the world, storing carbon, purifying water and air, and regulating climate. But keeping tabs on the health of this vulnerable biome has proven to be a painstaking and time-consuming undertaking – until now.

Cutting-edge DNA metabarcoding technology developed by the University of Guelph can help speed up and improve the monitoring process, according to a new study published today in Scientific Reports.

Surprising amount of rainforest loss occurs on – and off – mining leases, new study finds
