(CNN)Nine out of every 10 people on the planet breathe air that contains high levels of pollutants and kills 7 million people each year, according to a new study from the World Health Organization.

The study is an analysis of what the WHO says is the world's most comprehensive database on ambient air pollution. The organization collected the data from more than 4,300 cities and 108 countries. ... Read more about Which cities face most, least air pollution according to new WHO data

CLIMATE CHANGE, OCEAN ACIDIFICATION MITIGATION IN MARINE VEGETATION

“Blue carbon” is a term you might be hearing more often. It refers to marine vegetation that has an inherent ability to sequester carbon and mitigate the consequences of carbon dioxide (CO2) emissions.

Vegetated coastal habitats including seagrass meadows, mangrove forests and tidal marshes were the first to be labeled as blue carbon. These marine photosynthesizers take up CO2 from the surrounding seawater and sequester carbon in the plants and the sediments below them, similar to terrestrial forests, but far more effectively. ...

Ocean acidification may cause dramatic changes to phytoplankton

Oceans have absorbed up to 30 percent of human-made carbon dioxide around the world, storing dissolved carbon for hundreds of years. As the uptake of carbon dioxide has increased in the last century, so has the acidity of oceans worldwide. Since pre-industrial times, the pH of the oceans has dropped from an average of 8.2 to 8.1 today. Projections of climate change estimate that by the year 2100, this number will drop further, to around 7.8 — significantly lower than any levels seen in open ocean marine communities today. ...

WASHINGTON (AP) '€” A new study looking at 11,000 years of climate temperatures shows the world in the middle of a dramatic U-turn, lurching from near-record cooling to a heat spike.

Research released Thursday in the journal Science uses fossils of tiny marine organisms to reconstruct global temperatures back to the end of the last ice age. It shows how the globe for several thousands of years was cooling until an unprecedented reversal in the 20th century. ... Read more about Recent heat spike unlike anything in 11,000 years

The world is facing a fertiliser crisis, with far too little in some places, and far too much in others, a new report from the United Nations says today.

The mass application of nitrogen, phosphorus and other nutrients needed for plant growth has had huge benefits for world food and energy production, but it has also caused a web of water and air pollution that is damaging human health, causing toxic algal blooms, killing fish, threatening sensitive ecosystems and contributing to climate change, says the report, “Our Nutrient World”. ...

A breakthrough in the race to make useful products out of planet-heating CO2 emissions has been made in southern India.

A plant at the industrial port of Tuticorin is capturing CO2 from its own coal-powered boiler and using it to make baking soda. ... Read more about Indian firm makes carbon capture breakthrough
