Mongabay: The concentration of carbon dioxide in the atmosphere made the biggest jump last year since 1984, according to the World Meteorological Organization's (WMO) Greenhouse Gas Bulletin, raising alarm bells about society's inaction on curbing global warming. "Far from falling, the concentration of carbon dioxide in the atmosphere actually increased last year at the fastest rate for nearly 30 years," Michel Jarraud, the WMO Secretary General, said in a statement. "We must reverse this trend by cutting...

Nature World: When it comes to pollutants such a PCBs contaminating the bodies of animals, the polar bear is often at the top of the list of most-polluted animals, but new research suggests that Greenland sharks harbor even more alarmingly high levels of pollutants than polar bears. Greenland sharks are one of the largest living shark species. Growing up to 7 meters long and weighing up to a ton, their are dimensions comparable to a great white shark. Greenland sharks are also live farther north than any other...

When rain stops falling, particle concentrations rise

Guardian: Brief respite from January's recording breaking wet weather caused air pollution problems over eastern England. Cold still nights on the 20th and 21st meant that air pollution built up in towns and cities. In Leeds airborne particle concentrations reached 8 on the government's ten point air quality index. Hull and York experienced similar problems, along with Chesterfield and Nottingham. The same cold nights caused air pollution to reach level 6 across much of London with Brixton Road being a hotspot,...
