Lower Ozone levels in Houston linked to climate change

2015-05-18 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed

ScienceDaily: Researchers at the University of Houston have determined that climate change -- in the form of a stronger sea breeze, the result of warmer soil temperatures -- contributed to the drop in high-ozone days in the Houston area. Robert Talbot, professor of atmospheric chemistry, said that also should be true for coastal regions globally. The researchers describe their findings in a paper published this week in the journal Atmosphere. In addition to Talbot, they include first author Lei Liu, a doctoral...

LiveScience: About a third of Americans live in areas where allergies could be made worse by a combination of high ozone levels and ragweed pollen, according to a new report. The top cities with this allergy-inducing combo dubbed in the report as the "Sneeziest and Wheeziest" cities include Richmond, Virginia; Memphis, Tennessee; Oklahoma City; Philadelphia; Chattanooga, Tennessee; and Chicago, according to the report, from the Natural Resources Defense Council (NRDC), an environmental advocacy group based...

Global CO2 levels surge past 400-ppm mark for first time in millions of years

2015-05-08 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed

ClimateWire: Global CO2 levels rose above 400 parts per million for the first time ever in the modern era in March 2015, marking a significant milestone in the planet's progression toward a warmer future. The measurements were released by the National Oceanic and Atmospheric Administration. The last time CO2 levels were this high was 3 million years ago during the Pliocene era. There was little ice at the poles then. Ellesmere Island, which is today part of the Canadian tundra, had forests growing on it. ...
