Globally Averaged CO2 Levels Reach 400 parts per million in 2015
October 25, 2016 07:11 AM - World Meteorological Organization
Globally averaged concentration of carbon dioxide in the atmosphere reached the symbolic and significant milestone of 400 parts per million for the first time in 2015 and surged again to new records in 2016 on the back of the very powerful El Niño event, according to the World Meteorological Organization's annual Greenhouse Gas Bulletin.
Amazon Study Reveals that Rainstorms Transport Atmospheric Particles Essential for Cloud Formation
October 24, 2016 01:10 PM - Brookhaven National Laboratory
Understanding how tiny particles emitted by cars and factories affect Earth's climate requires accurate climate modeling and the ability to quantify the effects of these pollutant particles vs. particles naturally present in the atmosphere. One large uncertainty is what Earth was like before these industrial-era emissions began. In a paper just published in Nature, scientists collaborating on the GoAmazon study describe how they tracked particles in the largely pristine atmosphere over the Amazon rainforest, which has given them a way to effectively turn back the clock a few hundred years.
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.
Reducing ammonia pollution from cattle

Agriculture is responsible for 90% of all ammonia pollution in Europe, a considerable part of which comes from cattle manure management: a new study shows what steps to take to reduce this pollution.
Improved barn design, cleaning processes, and manure treatment could reduce ammonia emissions from commercial dairy cattle barns by 17 to 50%, according to a new study published in the journal Science of the Total Environment. The study provides a list of techniques and technologies that could provide the greatest reductions in ammonia emissions.
Salty snow could affect air pollution in the Arctic
October 13, 2016 08:03 PM - American Chemical Society
In pictures, the Arctic appears pristine and timeless with its barren lands and icy landscape. In reality, the area is rapidly changing. Scientists are working to understand the chemistry behind these changes to better predict what could happen to the region in the future. One team reports in ACS’ Journal of Physical Chemistry A that sea salt could play a larger role in the formation of local atmospheric pollutants than previously thought.
Scientists creating super grass to cut methane emissions from cows
October 13, 2016 02:02 PM - Yale Environment 360
Danish scientists are developing a grass that will cut down how often cows burp and pass gas — reducing the amount of methane, a potent greenhouse gas, they release into the atmosphere.
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."
To Help Bees, Skip Herbicides and Pesticides, Keep Lawns Naturally Diverse
October 7, 2016 04:23 PM - University of Massachusetts Amherst
Declining populations of pollinators is a major concern to ecologists because bees, butterflies and other insects play a critical role in supporting healthy ecosystems. Now a new study from urban ecologists at the University of Massachusetts Amherst suggests that when urban and suburban lawns are left untreated with herbicides, they provide a diversity of “spontaneous” flowers such as dandelions and clover that offer nectar and pollen to bees and other pollinators.
UC Researcher Develops Clean Water-Treatment Option to Target Sporadic Outbreaks
October 5, 2016 10:26 AM - John Bach
A University of Cincinnati scientist has engineered an environmentally friendly technology to zap outbreak-causing viruses and bacteria from public drinking water.
Environmental and biomedical engineer David Wendell, an associate professor in UC’s College of Engineering and Applied Science, developed a protein-based photocatalyst that uses light to generate hydrogen peroxide to eliminate E. coli, Listeria, and potentially protozoa like giardia and cryptosporidium.
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.
