Protecting people and planet from "invisible killer" is focus of UN health campaign to tackle air pollution
October 20, 2016 04:50 PM - United Nations News Centre
The United Nations World Health Organization (WHO) in partnership with the Coalition for Climate and Clean Air (CCAC) and the Government of Norway has launched a global awareness campaign on the dangers of air pollution – especially ‘invisible killers’ such as black carbon, ground-level ozone and methane – for the health of individuals and the planet.
Titled BreatheLife: Clean air. A healthy future, the campaign aims to mobilize cities and their inhabitants on issues of health and protecting the planet from the effects of air pollution. Moreover, By WHO and CCAC joining forces, ‘BreatheLife’ brings together expertise and partners that can tackle both the climate and health impacts of air pollution.
New 13-year Study Tracks Impact of Changing Climate on a Key Marine Food Source
October 20, 2016 03:08 PM - Woods Hole Oceanographic Institution
A new multiyear study from scientists at the Woods Hole Oceanographic Institution (WHOI) has shown for the first time how changes in ocean temperature affect a key species of phytoplankton. The study, published in the October 21 issue of the journal Science, tracked levels of Synechococcus—a tiny bacterium common in marine ecosystems—near the coast of Massachusetts over a 13-year period. As ocean temperatures increased during that time, annual blooms of Synechococcus occurred up to four weeks earlier than usual because cells divided faster in warmer conditions, the study found.
While global methane emissions are up, study says fossil fuels not the culprit
October 12, 2016 01:26 PM - Susan Phillips
A new study from NOAA, the National Oceanic Atmospheric Administration, puts a new twist on a tricky question about the impact of increased oil and gas production on greenhouse gas emissions. Scientists have detected increased rates of methane emissions globally since 2007. That uptick corresponds to the rapid boom in U.S. shale gas and shale oil production, and some hypothesized that the two could be connected. But it turns out that the correlation may not necessarily be a cause.
Pew: Renewable energy enjoys wide support while fossil fuels divide national opinion
October 12, 2016 12:39 PM - Robert Walton
Pew Research's "Politics of Climate" survey is a mixed bag for energy industry watchers, revealing a solid chunk of Americans support expanded fossil fuel use, while almost everyone supports renewables.
"One spot of unity in an otherwise divided environmental policy landscape is that the vast majority of Americans support the concept of expanding both solar and wind power," the think tank said in a blog post. "The public is more closely divided when it comes to expanding fossil fuel energies such as coal mining, offshore oil and gas drilling, and hydraulic fracturing for oil and natural gas."
European union could require new homes to have electric car chargers
October 11, 2016 02:33 PM - Yale Environment 360
Starting in 2019, all new or refurbished homes and apartment buildings in Europe will be required to have electric vehicle recharging stations built on the premises, according to a draft directive from the European Union.
Bees Are Declared Endangered for the First Time in the U.S.
October 7, 2016 07:09 AM - Alicia Graefi, Care2
For the first time in history, a group of bees in the U.S. will be protected under the Endangered Species Act, following a recent announcement from wildlife officials.
The group of bees, who are commonly known as yellow-faced bees because of the markings on their faces, are endemic only to the Hawaiian islands. While there are dozens of species, scientists identified several of them who are at risk of extinction and have been calling for their protection for years.
The Psychology Behind Climate Change Denial
October 5, 2016 06:53 AM - Uppsala University
Climate change is a serious threat to humans, animals, and the earth’s ecosystems. Nevertheless, effective climate action has been delayed, partly because some still deny that there is a problem. In a new thesis in psychology, Kirsti Jylhä at Uppsala University has studied the psychology behind climate change denial. The results show that individuals who accept hierarchical power structures tend to a larger extent deny the problem.
In the scientific community there is a strong consensus that humans have significantly affected the climate and that we are facing serious challenges. But there is a lot of misinformation about climate change in circulation, which to a large part is created and distributed by organised campaigns with the aim of postponing measures that could combat climate change. And there are people who are more prone than others to trust this misinformation.
Previous research has consistently shown that it is more common among politically conservative individuals to deny climate change. In her thesis, Kirsti Jylhä has investigated this further and in more detail. Her studies included ideological and personality variables which correlate with political ideology, and tested if those variables also correlate with climate change denial.
New Technology Helps Pinpoint Sources of Water Contamination

Berkeley Lab develops better method of environmental monitoring using the PhyloChip, finds surprising results in Russian River watershed
When the local water management agency closes your favorite beach due to unhealthy water quality, how reliable are the tests they base their decisions on? As it turns out, those tests, as well as the standards behind them, have not been updated in decades. Now scientists from Lawrence Berkeley National Laboratory (Berkeley Lab) have developed a highly accurate, DNA-based method to detect and distinguish sources of microbial contamination in water.
Longest record of continuous carbon flux data is now publicly available
September 28, 2016 10:04 AM - Lawrence Berkeley National Laboratory via ScienceDaily
Around the world -- from tundra to tropical forests, and a variety of ecosystems in between -- environmental researchers have set up micrometeorological towers to monitor carbon, water, and energy fluxes, which are measurements of how carbon dioxide (CO2), water vapor and energy (heat) circulate between the soil, plants and atmosphere. Most of these sites have been continuously collecting data, some for nearly 25 years, monitoring ecosystem-level changes through periods of extreme droughts and rising global temperatures. Each of these sites contributes to a regional network -- i.e. the European Network (Euroflux) or the Americas Network (AmeriFlux) -- and the regional networks together comprise a global network called FLUXNET.
It May Not Cost You More To Drive Home In A Climate-Friendly Car
September 27, 2016 02:34 PM - NPR
It has been a common belief that low-emissions vehicles, like hybrids and electric cars, are more expensive than other choices. But a new study finds that when operating and maintenance costs are included in a vehicle's price, cleaner cars may actually be a better bet.
