CO2 levels for February eclipsed prehistoric highs
2015-03-06 15:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Scientific American: February is one of the first months since before months had names to boast carbon dioxide concentrations at 400 parts per million.* Such CO2 concentrations in the atmosphere have likely not been seen since at least the end of the Oligocene 23 million years ago, an 11-million-year-long epoch of gradual climate cooling that most likely saw CO2 concentrations drop from more than 1,000 ppm. Those of us alive today breathe air never tasted by any of our ancestors in the entire Homo genus. Homo sapiens...

Perry Misses Point on Texas CO2 Cuts
2015-03-04 21:42:00| Climate Ark Climate Change & Global Warming Newsfeed
Fact Check: Rick Perry said carbon dioxide emissions in Texas were down because of "incentive-based regulation" during his time as governor. But the evidence shows a decline in manufacturing jobs and federal energy policies - not the state`s - are more likely to be the cause of the reduction. Perry pointed to policies that upgraded old diesel engines. But the nitrogen oxide figures he cited actually exclude vehicles, and transportation sector CO2 rose over the time frame in question. The CO2 reduction was...
For First Time in Nature Scientists Measure Heat-Trapping Effects of CO2
2015-02-26 20:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: Scientists have long understood how carbon dioxide traps heat in the atmosphere and contributes to global warming, but the phenomenon had not been directly documented at the earth's surface outside of a laboratory until now. Writing in the journal Nature, researchers present 11 years of field data on carbon dioxide's capacity to absorb thermal radiation emitted from the surface of the earth. The results agree with theoretical predictions of the greenhouse effect associated with fossil fuel combustion,...
Combined Technology To Reduce US CO2 Emissions
2015-02-23 03:03:39| pollutiononline News Articles
Energy efficiency is of increasing concern for many businesses. In 2012, the EPA estimated 39% of electricity was generated from coal-fired power stations, which contributed 75% of the total 6,526 million metric tons of CO2 equivalents
