A new study finds that Canada could remove at least five times its annual carbon emissions with strategic planting of more than six million hectares of trees along the northern edge of the boreal forest.
York U Researchers Develop New Technique to Measure Previously Undetected Airborne PFAS
For decades, scientists knew there was a huge swath of undetected and unaccounted for per- and polyfluoroalkyl substances (PFAS) in the atmosphere, often referred to as PFAS dark matter, but no one knew how much was missing or how to measure them.
Concordia Study Finds Snow Droughts in Western and Southern Canada Could Affect Nearly All Canadians
Researchers at Concordia have developed a new method of measuring the amount of usable water stored in snowpacks.
Ancient oceans stayed oxygen rich despite extreme warming
Scientists studying ancient ocean fossils found that the Arabian Sea was better oxygenated 16 million years ago, even though the planet was warmer than today. Oxygen levels only plunged millions of years later, after the climate cooled, defying expectations. Powerful monsoons and ocean circulation appear to have delayed oxygen loss...
Tiny mammals are sending warning signs scientists can finally read
Small mammals are early warning systems for environmental damage, but many species look almost identical, making them hard to track. Scientists have developed a new footprint-based method that can tell apart nearly indistinguishable species with remarkable accuracy. Tested on two types of sengi, the system correctly identified them up to...
A breakthrough that turns exhaust CO2 into useful materials
Scientists have created a device that captures carbon dioxide and transforms it into a useful chemical in a single step. The new electrode works with realistic exhaust gases rather than requiring purified CO2. It converts the captured gas into formic acid, which is used in energy and manufacturing. The system...
Cleaner Ship Fuel Changed Clouds, But Not Their Climate Balance
To reduce air pollution associated with ocean transport, the International Maritime Organization tightened restrictions on sulfur content in ship fuel, resulting in an 80% reduction in emissions by 2020.
Mineral Dust Accelerating Melting of Greenland Ice Sheet
Large-scale melting of the Greenland Ice Sheet is irreversible and happening at a rapid rate, and now a new international study is the first to understand why.
Farm Waste Could Lock Away Carbon for Decades
Agricultural waste that is usually burned or left to rot could play a far bigger role in tackling climate change if it were instead used in long-lasting building materials, according to new research from the University of East London (UEL).
This spider’s “pearl necklace” was living parasites
What looked like a pearl necklace on a tiny spider turned out to be parasitic mite larvae. Scientists identified the mites as a new species, marking the first record of its family in Brazil. The larvae attach to juvenile spiders and feed on lymph through a weak spot in the...
