The Baltic Sea is home to some of the world’s largest dead zones, areas of oxygen-starved waters where most marine animals can’t survive. But while parts of this sea have long suffered from low oxygen levels, a new study by a team in Finland and Germany shows that oxygen loss in coastal areas over the past century is unprecedented in the last 1500 years. The research is published today in the European Geosciences Union journal Biogeosciences.

One of Canada’s largest pension fund’s continued and increasing investment in fossil fuels does not support the widely held goal of limiting global warming to 2°C above pre-industrial levels, says a new report by University of Victoria and University of British Columbia researchers affiliated with the Corporate Mapping Project, a six-year research and public engagement initiative.

The decline in China’s carbon emissions is likely to be sustained if changes to the country’s industrial structure and energy efficiency continue, according to new research led by the University of East Anglia (UEA).

As the story of lead contamination in the water of Flint, Michigan, was unfolding in the national news, Elena Sobrino was finishing up her undergraduate degree at the University of Michigan at Flint.

In 2015, exposure to particulate matter in sub-Saharan Africa led to 400,000 otherwise preventable infant deaths, according to a new Stanford study. The research published this week in Nature, finds that even modest improvements in air quality could lead to substantial reductions in infant mortality in developing countries.

Why do individuals respond differently to the same environment? Researchers from North Carolina State University and Oregon State University have pinpointed a genetic difference in zebrafish tied to differing responses to the same environmental chemical. The work could have implications for identifying genetic factors that explain differential chemical sensitivity.

Carbon dioxide emissions from human activities must approach zero within several decades to avoid risking grave damage from the effects of climate change.  This will require creativity and innovation, because some types of industrial sources of atmospheric carbon lack affordable emissions-free substitutes, according to a new paper in Science from team of experts led by University of California Irvine’s Steven Davis and Carnegie’s Ken Caldeira.

With the help of this new method, waste water can be treated faster than before, and the environmentally positive aspect is that the process leaves less solid radio-active waste.

The U.S. oil and gas industry emits 13 million metric tons of the potent greenhouse gas methane from its operations each year, 60 percent more than estimated by the U.S. Environmental Protection Agency, according to a new study published today in the journal Science.

Even though it was closed decades ago, the Giant Mine on the outskirts of Yellowknife has left a long environmental legacy.
