Fine particulate matter air pollution may be associated with blood vessel damage and inflammation among young, healthy adults, according to new research in Circulation Research, an American Heart Association journal.

“These results substantially expand our understanding about how air pollution contributes to cardiovascular disease by showing that exposure is associated with a cascade of adverse effects,” said C. Arden Pope, Ph.D., study lead author and Mary Lou Fulton Professor of Economics at Brigham Young University in Provo, Utah.

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.

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.

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. 

Nearly two years ago, Sandia National Laboratories researchers Joe Pratt and Lennie Klebanoff set out to answer one not-so-simple question: Is it feasible to build and operate a high-speed passenger ferry solely powered by hydrogen fuel cells? The answer is yes.

The details behind that answer are in a recent report, “Feasibility of the SF-BREEZE: a Zero Emission, Hydrogen Fuel Cell High Speed Passenger Ferry.” SF-BREEZE stands for San Francisco Bay Renewable Energy Electric Vessel with Zero Emissions.

Following the news that the UK government is to ban plastic microbeads by the end of 2017, a team of scientists led by the University of Oxford has discovered the first evidence of microplastics being ingested by deep-sea animals.

Researchers working on the Royal Research Ship (RRS) James Cook at two sites in the mid-Atlantic and south-west Indian Ocean found plastic microfibres inside creatures including hermit crabs, squat lobsters and sea cucumbers at depths of between 300m and 1800m.

Household dust exposes people to a wide range of toxic chemicals from everyday products, according to a study led by researchers at Milken Institute School of Public Health (Milken Institute SPH) at the George Washington University. The multi-institutional team conducted a first-of-a-kind meta-analysis, compiling data from dust samples collected throughout the United States to identify the top ten toxic chemicals commonly found in dust. They found that DEHP, a chemical belonging to a hazardous class called phthalates, was number one on that list. In addition, the researchers found that phthalates overall were found at the highest levels in dust followed by phenols and flame retardant chemicals.

Survival of the fittest. This basic tenet of evolution explains why the dodo bird no longer exists and why humans have opposable thumbs.

Adaptation is key to survival, no matter how many fingers you’ve got. The ability to adjust to whatever conditions Mother Earth sends our way determines whether obstacles lead to extinction or to a new generation.

Human-accelerated climate change is a disaster waiting to happen. We’ve already seen the superstorms and drought it can create. Although we can work to slow climate change, there’s no way to stop it completely. This reality means adaptation will once again become the most important strategy for survival.

One thing’s for sure: the Earth will continue to exist as it has for eons. The question is, what will be left behind to inhabit it?

Below are five species known for their resilience and ability to survive in adverse conditions. They are the most likely to survive a climate change disaster. Spoiler: humans don’t make the list.

A new WHO air quality model confirms that 92% of the world's population lives in places where air quality levels exceed WHO limits. Some 3 million deaths a year are linked to exposure to outdoor air pollution. Indoor air pollution can be just as deadly. In 2012, an estimated 6.5 million deaths (11.6% of all global deaths) were associated with indoor and outdoor air pollution together.

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.
