Trees Using Water More Efficiently Due To Increase in Atmospheric Carbon Dioxide
2013-07-14 18:01:00| Climate Ark Climate Change & Global Warming Newsfeed
Science World Report: A paper published online in the journal Nature Wednesday, examines how a dramatic change in atmospheric carbon dioxide levels makes trees thriftier with water. It is a known fact that atmospheric carbon dioxide boosts the growth of plants. To state that carbon dioxide is an important plant food is not a new argument. Many experts have expressed concerns over the fate of forests in the face of climatic changes taking place because such alterations directly and indirectly affect the growth and productivity...

Atmospheric CO2 Concentrations Surpass 400 PPM Milestone In May 9 Daily Average
2013-05-10 13:35:00| Climate Ark Climate Change & Global Warming Newsfeed
Huffington Post: Atmospheric concentrations of carbon dioxide surpassed a notable milestone this week. They reached a daily average above 400 parts per million, reported NOAA, for the first time in human history. The milestone, hit on May 9, may be symbolic, notes Climate Central, but manmade CO2 emissions from the burning of fossil fuels continue to rise, bringing greater atmospheric warming and exacerbating the effects of climate change. Scientists argue we've loaded the "climate dice" in favor of more...

400 ppm atmospheric CO2 levels soon to be surpassed, scientists report
2013-04-30 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Huffington Post: Scientists monitoring global atmospheric carbon dioxide concentrations report that, for the first time in human history, CO2 levels could soon rise above 400 parts per million for a sustained period of time in much of the Northern Hemisphere. Hourly readings have surpassed 400 ppm in the past week, but daily averages remain just below 400, reported The Guardian. Daily readings are expected to surpass 400 ppm in early May. They will reach their annual peak by mid-month. The measurements come...
