A 'national conversation' is needed to combat the worrying levels of air pollution in some city-based classrooms, say researchers from the University of Surrey.
Climate change is a global environmental concern. A major contribution to climate change comes from excessive burning of fossil fuels.
Over 44 million people in the United States depend on private drinking water wells that are not federally regulated. Researchers at the University of New Hampshire and collaborating institutions found that current monitoring practices do not accurately reflect groundwater pollution risks because spikes in harmful bacteria, like those from animal and human waste, vary depending on the season—with highest levels observed from testing conducted in summer months when temperatures are over 90°F.
A study of adolescents aged 11-16 in London has found long-term exposure to PM2.5 is associated with higher blood pressure, with stronger associations seen in girls.
Declining water levels of Great Salt Lake threaten economic activity, local public health, and ecosystems. In response to this emergent statewide challenge, Utah’s research universities formed the Great Salt Lake Strike Team, a collaboration of experts in public policy, hydrology, water management, climatology, and dust. Today they released a Great Salt Lake Policy Assessment that affirms the situation is urgent, but also identifies a variety of policy levers that can return the lake to healthy levels.
The University of Miami is welcoming leaders from institutions across the nation this week at the Higher Education Climate Leadership Summit to share ideas on combating the climate crisis.
The world generates about 300 million tons of plastic waste annually, and more than 90% of all plastic ever made has never been recycled. Part of what drives all that waste into landfills or into the environment is the difficulty of recycling plastic, which is designed to last for a very long time. Traditional plastic recycling suffers from a fundamental flaw, said Marcus Foston: there’s no financial incentive for companies to do it.
The UK’s laundry releases microfibres weighing the equivalent of up to 1,500 double-decker buses in microfibres every year, according to new research.
With its high-carbon footprint, air travel challenges the goal set by many countries of stabilizing global mean temperature by the middle of the 21st century.

If you live near a busy road, it may increase your stress levels and affect your sleep. When we are under stress and sleep poorly, we may be at a higher risk of developing tinnitus.
Human actions are changing the environment at an unprecedented rate. Plant and animal populations must try to keep up with these human-accelerated changes, often by trying to rapidly evolve tolerance to changing conditions.
While microplastics have received significant attention in recent years for their negative environmental impacts, a new study from Oregon State University scientists found microfibers from synthetic materials as well as cotton impacted the behavior and growth of water organisms.
Iowa State's Xianglan Bai is leading two, $2-million-plus projects that will study and develop new ways to break down waste plastics and convert them to useful materials. The U.S. Department of Energy is supporting both projects.
Small isolated wetlands that are full for only part of the year are often the first to be removed for development or agriculture, but a new study shows that they can be twice as effective in protecting downstream lake or river ecosystems than if they were connected to them.
New UC Riverside research suggests nitrogen released by gas-powered machines causes dry soil to let go of carbon and release it back into the atmosphere, where it can contribute to climate change.

A Missouri University of Science and Technology research group was recently awarded a grant from the Environmental Protection Agency (EPA) that is aimed at preventing pollution in the mining industry.
Coastal city residents would like to do more to reduce their single-use plastic waste and they are trying to recycle more, even trying to recycle items that simply can’t be recycled, often called “wish-cycling”.
A new study finds that proximity to electric vehicle charging stations (EVCSs) can raise property values depending on where homes are situated. The study, conducted by a team of researchers from the University of Rhode Island, the University of Maryland College Park, Princeton University and Cardiff University, was recently published in Nature Sustainability.
A Ross School of Business startup that helped accelerate the removal of dangerous lead pipes in Flint and many other communities has joined a White House partnership aimed at replacing all of the nation’s lead service lines in a decade.

The U.S. Consumer Product Safety Commission (CPSC), a federal agency, is not currently considering a ban on gas stoves. Therefore the claim that the government is banning gas stoves or that they plan on seizing people’s stoves is false.
About a quarter of the world’s electricity currently comes from power plants fired by natural gas. These contribute significantly to global greenhouse gas emissions (amounting to 10% of energy-related emissions according to the most recent figures from 2017) and climate change.
On Jan. 9, a United Nations-backed panel of experts announced that Earth’s protective ozone layer is on track to recover within four decades, closing an ozone hole over the Antarctic that was first noticed in the 1980s. But it was research conducted at the University of California, Irvine in the 1970s that made this good new possible.
