Bad air quality is deadly

New research shows that more than 5.5 million people die prematurely every year due to household and outdoor air pollution. More than half of deaths occur in two of the world's fastest growing economies, China and India.

Power plants, industrial manufacturing, vehicle exhaust and burning coal and wood all release small particles into the air that are dangerous to a person's health. New research, presented today at the 2016 annual meeting of the American Association for the Advancement of Science (AAAS), found that despite efforts to limit future emissions, the number of premature deaths linked to air pollution will climb over the next two decades unless more aggressive targets are set.

"Air pollution is the fourth highest risk factor for death globally and by far the leading environmental risk factor for disease," said Michael Brauer, a professor at the University of British Columbia's School of Population and Public Health in Vancouver, Canada. "Reducing air pollution is an incredibly efficient way to improve the health of a population."

Land surfaces are storing more water slowing sea level rise

New measurements from a NASA satellite have allowed researchers to identify and quantify, for the first time, how climate-driven increases of liquid water storage on land have affected the rate of sea level rise.

A new study by scientists at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, California, and the University of California, Irvine, shows that while ice sheets and glaciers continue to melt, changes in weather and climate over the past decade have caused Earth's continents to soak up and store an extra 3.2 trillion tons of water in soils, lakes and underground aquifers, temporarily slowing the rate of sea level rise by about 20 percent.

The water gains over land were spread globally, but taken together they equal the volume of Lake Huron, the world's seventh largest lake. The study is published in the Feb. 12 issue of the journal Science.

Carbon dioxide stored underground can find multiple ways to escape

When carbon dioxide is stored underground in a process known as geological sequestration, it can find multiple escape pathways due to chemical reactions between carbon dioxide, water, rocks and cement from abandoned wells, according to Penn State researchers.

Sandia National Laboratories improves modeling of Greenland and Antarctic ice sheets

The Greenland and Antarctic ice sheets will make a dominant contribution to 21st century sea-level rise if current climate trends continue. However, predicting the expected loss of ice sheet mass is difficult due to the complexity of modeling ice sheet behavior.

To better understand this loss, a team of Sandia National Laboratories researchers has been improving the reliability and efficiency of computational models that describe ice sheet behavior and dynamics. The team includes researchers Irina Demeshko, Mike Eldred, John Jakeman, Mauro Perego, Andy Salinger, Irina Tezaur and Ray Tuminaro.

Will you take part in this year's Great Backyard Bird Count?

This weekend bird enthusiasts from around the world will become citizen scientists for a few days during the 19th annual Great Backyard Bird Count, which is happening this year February 12-15.

During this four-day event, which is organized by the Cornell Lab of Ornithology, the National Audubon Society and Bird Studies Canada, people will be headed outdoors to count their local birds in the name of science.

Obama Administration's "Clean Power Plan" dealt a setback by the Supreme Court

The Obama administration’s Clean Power Plan suffered a setback on Tuesday when the Supreme Court granted a stay to the program. In a 5-4 decision, the court sided in favor of petitioning states, utilities and coal companies that claimed that the federal government was overreaching its powers when it attempted to establish a national plan to move away from fossil-fuel based power. Requests for the Supreme Court to impose the stay were submitted in January after an appeals court ruled that the plan could proceed while legal challenges were being heard.

The Supreme Court’s ruling is an about-face to the U.S. Court of Appeals for the District of Columbia Circuit, and it comes at a critical time for the Obama administration’s clean energy program, especially in light of the upcoming elections in November. While the administration can appeal the Supreme Court’s order, arguments would not be considered until June and, pending acceptance by the higher court, likely wouldn’t be scheduled until October or later this year. That leaves the fate of the Clean Power Plan in the hands of the upcoming presidency.

Warmer climate contributes to spread of the Zika virus

The Aedes mosquitos that carry the Zika virus and dengue fever are not just perfectly adapted to life in cities, writes Nadia Pontes. They are also being helped along by warming climates which increase their range. It's time to get serious about the health implications of a hotter planet.

Global warming affects the abundance and distribution of disease vectors. As regions that used to be drier and colder start to register higher temperatures and more rain, mosquitoes expand their breeding areas, which increases the number of populations at

The explosion in the number of Latin American cases of microcephaly - a congenital condition associated with maldevelopment of the brain - has become an international emergency due its "strongly suspected"link with the rapidly spreading Zika virus, according to the World Health Organisation(WHO).

Climate change will delay transatlantic flights

Planes flying between Europe and North America will be spending more time in the air due to the effects of climate change, a new study has shown.

By accelerating the jet stream – a high-altitude wind blowing from west to east across the Atlantic – climate change will speed up eastbound flights but slow down westbound flights, the study found.  The findings could have implications for airlines, passengers, and airports.

Are we impacting the future of our planet for thousands of years?

The Earth may suffer irreversible damage that could last tens of thousands of years because of the rate humans are emitting carbon into the atmosphere.

In a new study in Nature Climate Change, researchers at Oregon State University, Lawrence Livermore National Laboratory and collaborating institutions found that the longer-term impacts of climate change go well past the 21st century.

“Much of the carbon we are putting in the air from burning fossil fuels will stay there for thousands of years — and some of it will be there for more than 100,000 years,” said Peter Clark, an Oregon State University paleoclimatologist and lead author on the article. “People need to understand that the effects of climate change on the planet won’t go away, at least not for thousands of generations.”

LLNL’s Benjamin Santer said the focus on climate change at the end of the 21st century needs to be shifted toward a much longer-term perspective.

Over 50 Percent of the World Breathes in Toxic Air

Everyone needs clean air to survive, yet somehow it is not an internationally recognized human right. That probably has something to do with the fact that over half of the world’s population live in areas where they breathe in toxic air. Altogether, that means there are more than 3.5 billion people inhaling dangerous air into their lungs on a daily basis.
