Global Warming Caused by CFCs, Not Carbon Dioxide, Researcher Claims in Controversial Study
2013-05-30 20:24:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Chlorofluorocarbons (CFCs) are to blame for global warming since the 1970s and not carbon dioxide, according to a researcher from the University of Waterloo in a controversial new study published in the International Journal of Modern Physics B this week. CFCs are already known to deplete ozone, but in-depth statistical analysis now suggests that CFCs are also the key driver in global climate change, rather than carbon dioxide (CO2) emissions, the researcher argues. "Conventional thinking says...

We've reached a troubling carbon dioxide milestone
2013-05-29 13:16:00| Climate Ark Climate Change & Global Warming Newsfeed
New Scientist: Atmospheric scientist Ralph Keeling explains the importance of measuring a CO2 concentration of 400 parts per million at the observatory his father set up The Mauna Loa Observatory in Hawaii has reportedly recorded a carbon dioxide concentration there of 400 parts per million for the first time. How significant is that? It's a psychological milestone. Every year in the last few decades, CO2 concentrations have been going up by about 2 ppm per year. Those changes go unnoticed but people pay...

Carbon dioxide in atmosphere did not break 400 ppm at Hawaii site
2013-05-14 14:37:09| Climate Ark Climate Change & Global Warming Newsfeed
LA Times: Carbon dioxide measurements in the Earth's atmosphere did not break the symbolic milestone of 400 parts per million at a Hawaiian observatory last week, according to a revised reading from the nation's climate observers. The National Oceanic and Atmospheric Administration (NOAA) revised its May 9 reading at the Mauna Loa observatory in Hawaii, saying it remained fractions of a point below the level of 400 ppm, at 399.89. Individual readings at any of NOAA's observation stations are subject...
