Pollution levels in the Indian capital this month have rivalled 1952 London, when smog killed around 4,000 people, pollution experts say. 

Research led by Oxford University highlights the accelerating pressure on measuring, monitoring and managing water locally and globally. A new four-part framework is proposed to value water for sustainable development to guide better policy and practice.

Excess carbon dioxide, emitted by burning fossil fuels like coal and petroleum, is one of the most important factors in driving global warming. While the world is focused on controlling these emissions to limit climate change, less attention has been paid to the capacity of vegetation and soils to take up and store carbon.

The flow of China’s carbon emissions has reversed according to new research led by scientists at the University of East Anglia.

The solar sector has surpassed coal as the largest generator of new electricity in India, accounting for 39 percent of new electricity production in 2017, according to new data.

Power stored in electric cars could be sent back to the grid – thereby supporting the grid and acting as a potential storage for clean energy – but it will only be economically viable if we upgrade the system first. In a new paper in Energy Policy, two scientists show how their seemingly contradictory findings actually point to the same outcome and recommendations: that pumping energy back into the grid using today’s technology can damage car batteries, but with improvements in the system it has the potential to provide valuable clean energy – and improve battery life in the process.

Throughout the United States, toxic algal blooms are wreaking havoc on bodies of water, causing pollution and having harmful effects on people, fish and marine mammals.

Ribbed mussels can remove nitrogen and other excess nutrients from an urban estuary and could help improve water quality in other urban and coastal locations, according to a study in New York City’s Bronx River. The findings, published in Environmental Science and Technology, are part of long-term efforts to improve water quality in the Bronx River Estuary.

The “social cost of carbon” — an influential figure used by policymakers to weigh the value of efforts that reduce greenhouse gas emissions — is outdated and underestimated. Updated estimates focused on the agricultural sector alone more than double the social cost of carbon, according to analysis from the University of California, Davis, and Purdue University.

When a Cornell-led team of scientists analyzed two dozen environmental factors to understand bumblebee population declines and range contractions, they expected to find stressors like changes in land use, geography or insecticides.
