A privately funded satellite is set to push methane tracking into a new era, once it launches into space on Monday.A collaborative mission between Environmental Defense Fund, Google, the Government of New Zealand and several other partners, MethaneSAT will track methane emissions around the globe in attempts to identify and quantify sources spewing the climate-heating greenhouse gas. For 20 years after its release into the atmosphere, methane gas is 80 times more harmful than carbon dioxide in its ability to increase…

For the ninth straight month, Earth has obliterated global heat records — with February, the winter as a whole and the world's oceans setting new high-temperature marks, according to the European Union climate agency Copernicus.The latest record-breaking in this climate change-fuelled global hot streak includes sea surface temperatures that weren't just the hottest for February, but eclipsed any month on record, soaring past August 2023's mark and still rising at the end of the month.And February, as well the previous two…

A volcano in southwestern Iceland erupted on Thursday for the third time since December, sending jets of lava into the sky and triggering the evacuation of the Blue Lagoon spa, one of the island country's biggest tourist attractions.The eruption began at about 1 a.m. ET along a three-kilometre fissure northeast of Mount Sýlingarfell, the Icelandic Meteorological Office said. Several communities on the Reykjanes Peninsula were cut off from heat and hot water after a river of lava engulfed a supply pipeline.The strength of…

Canada's forestry sector is responsible for far more greenhouse gas emissions than show up in official tallies, potentially leading to policies that aren't in line with the country's climate goals, a new study suggests.The peer-reviewed study, published in the academic journal Frontiers in Forests and Global Change, found that annual greenhouse gas emissions attributable to forestry between 2005 and 2021 were, on average, nearly 91 million tonnes of carbon dioxide equivalent — which would put the sector on par with…

By now, most people are well aware that 2023 was the hottest year on record, coming in at 1.48 C warmer than the pre-industrial average from 1850-1900. This beat out 2016's record of 1.25 C.  In climate terms, an increase in warming by 0.23 C is considerable and climate scientists are still trying to figure out why it happened.Was 2023 just a big blip on the upward trend of global warming? Perhaps. Scientists are trying to tease out all the potential contributors.But one of the things that is inarguably a contributor is…

The Rocky Mountains conjure up images of grey rugged peaks capped with white. But within the upper reaches of the harsh mountain landscapes, a rosier hue often blooms.Watermelon snow, also known as glacial blood, is caused by algae that turns the snow a startling shade of red.The algae blooms in summer, forming on the snowfields that linger on glaciers, frozen lakes, rugged peaks and icy valleys in the upper reaches of mountain terrain.The darker the snow, the faster it melts — and new research sheds light on the threat…

After a year of record-breaking wildfires across Canada and the hottest temperature ever recorded on Earth, it likely comes as no surprise that 2023 was the hottest year on record.According to the European Union's Copernicus Climate Change Service (C3S), 2023 was 1.48 C warmer than the pre-industrial average from 1850-1900, beating out 2016's record of 1.25 C.

A volcano that had rumbled for weeks erupted in southwestern Iceland, spewing semi-molten rock into the air in a spectacular show of Earth's power in the land known for fire and ice.The eruption that started Monday night occurred about four kilometres from the town of Grindavik, the Icelandic Meteorological Office said. The town near Iceland's main airport was evacuated in November after thousands of earthquakes damaged homes and raised fears of an imminent eruption.On Tuesday, fountains of orange lava shot into the…

As Hurricane Larry lashed Newfoundland in 2021, university students from Halifax headed to a rural area in its track to find out whether the ocean might whip microplastics up into the atmosphere then transport them by air to otherwise pristine communities.The results, you could say, blew their socks off."It was such, like, an astonishing result that we weren't really expecting," said Anna Ryan, a Dalhousie University environmental science masters student and the study's lead researcher. To test their theory, the…
