So-Called ‘Safe’ Pesticides Have Surprising Ill Effects
Health Canada is currently reviewing regulations for pesticides in Canada, and three UBC researchers say regulators might want to consider what happened in Japan.
Researchers Develop Machine Learning Model to Improve Amazon Carbon Storage Estimates
A collaboration led by an Oregon State University College of Forestry researcher has used very-high-resolution satellite imagery to develop a machine learning model that aims to improve climate scientists’ ability to estimate aboveground carbon stocks in the Amazon.
Improving Health Outcomes by Targeting Climate and Air Pollution Simultaneously
Climate policies are typically designed to reduce greenhouse gas emissions that result from human activities and drive climate change.
New Research Reveals 12 Ways Aquaculture Can Benefit the Environment
Aquaculture, or the farming of aquatic plants and animals, contributes to biodiversity and habitat loss in freshwater and marine ecosystems globally, but when used wisely, it can also be part of the solution, new research shows.
Vehicle Emissions May Cause Over 11,000 Deaths a Year, Researchers Say
New estimates by Melbourne Climate Futures researchers shows that health impacts from vehicle emissions are likely to be far higher than previous figures informing policy decisions, as a broad group of air pollution experts call for urgent action to clear the air.
