• Policies to Curb Short-Lived Climate Pollutants Could Yield Major Health Benefits

    A commitment to reducing global emissions of short-lived climate pollutants (SLCPs) such as methane and black carbon could slow global warming while boosting public health and agricultural yields, aligning the Paris Climate Agreement with global sustainable development goals, a new analysis by an international research panel shows.

    Methane and black carbon – or soot – are the second and third most powerful climate-warming agents after carbon dioxide. They also contribute to air pollution that harms the health of billions of people worldwide and reduces agricultural yields.

  • Modified soybeans yield more in future climate conditions

    By 2050, we will need to feed 2 billion more people on less land. Meanwhile, carbon dioxide levels are predicted to hit 600 parts per million—a 50% increase over today’s levels—and 2050 temperatures are expected to frequently match the top 5% hottest days from 1950-1979. In a three-year field study, researchers proved engineered soybeans yield more than conventional soybeans in 2050’s predicted climatic conditions.

  • Shunned by microbes, organic carbon can resist breakdown in underground environments, Stanford scientists say

    The soils and sediments beneath our feet can contain an astonishing amount of carbon – more than in all of the world’s plants and the atmosphere combined – and represents a significant potential source of the greenhouse gas carbon dioxide.

    In a new study, Stanford scientists have uncovered a previously unknown mechanism that explains why microbes sometimes fail to break down all the plant and animal matter, leaving carbon underfoot. Understanding where, and how long, this buried organic matter lingers is crucial for scientists and policymakers to better predict and respond to climate change.

  • Scientists Find Real-time Evidence of Morphological Changes of Dust Particles due to Internally Mixing with Pollution

    Frequent occurrence of both anthropogenic pollution and natural dust in East Asian imposes great impact on regional air quality, human health and climate. Till now, their interaction and consequent effect on the dust morphology remain statistically unclear because even though traditional filter-based bulk sampling method can provide accurate chemical compounds, it cannot distinguish the mixing state of chemicals with dust particles.

  • Fifty years ago, a historic balloon launch that changed the way we see the ozone layer

    From atop this grassy mesa in 1967, scientists with the federal Environmental Science Services Agency carefully launched a weather balloon carrying a new instrument that could measure ozone levels from the ground to the very edge of outer space -- and radio the data back to a ground receiver.

  • As government delays pollution plan, study shows how killer nanoparticles cause heart disease

    A new study explains for the first time how nanoparticles like those in diesel exhaust fumes cause heart disease by lodging in inflamed blood vessels, writes Oliver Tickell. The study, published as the UK government is ordered before the High Court to justify its refusal to publish plans to tackle illegal air pollution which afflicts 38 million people, also raises wider fears about 'engineered nanoparticles' in the environment.

  • Deepwater Horizon oil spill settlements: Where the money went

    On April 20, 2010, the Deepwater Horizon oil rig exploded off the Gulf Coast, killing 11 people and injuring 17. So began an 87-day oil spill that spewed 3.19 million barrels, or nearly 134 million gallons, into the Gulf of Mexico. It fouled the coasts of Florida, Alabama, Mississippi, Louisiana and Texas and launched a six-year long environmental and legal battle.

  • India's outsized coal plans would wipe out Paris climate goals

    India will not be able to meet its Paris climate agreement commitments in the coming years if it carries through with plans to construct nearly 370 coal-fired power plants, according to University of California, Irvine and CoalSwarm researchers.

    “India is facing a dilemma of its own making,” said UCI associate professor of Earth system science Steven Davis, co-author of a study published today in the American Geophysical Union journal Earth’s Future. “The country has vowed to curtail its use of fossil fuels in electricity generation, but it has also put itself on a path to building hundreds of coal-burning power plants to feed its growing industrial economy.”

  • Antarctica's biodiversity is under threat from tourism, transnational pollution and more

    A unique international study has debunked the popular view that Antarctica and the Southern Ocean are in much better ecological shape than the rest of the world.

    The study, published recently in PLOS Biology and involving an interdisciplinary group of 23 researchers, compared Antarctic biodiversity and its management with that of the rest of the world.

  • Clean power planning

    With a single executive order issued at the end of March, the Trump administration launched a robust effort to roll back Obama-era climate policies designed to reduce U.S. carbon dioxide (CO2) emissions. Chief among those policies is the Clean Power Plan, which targets coal and natural gas-fired electric power plants that account for about 40 percent of the nation’s CO2 emissions. Private and public-sector investors may see the executive order as a green light to double down on relatively cheap fossil fuels and reduce holdings in more costly, climate-friendly, non-carbon generation technologies such as wind, solar and nuclear. But they may want to think twice before making such transactions.
