Anti-green group derides Gingrich’s likely ‘Democratic’ presidential bid | The Colorado Independent
A political nonprofit labeling itself the “nation’s largest grassroots opponent of radical environmentalism” sarcastically welcomed the anticipated presidential candidacy of Republican Newt Gingrich on Monday, calling the former U.S. Speaker of the House “Al Gore hiding under a Phil Donahue wig.”
CO2-Enriched Trees Extracting Needed Nitrogen from Nitrogen-Poor Soil
In consequence of their experimental findings, Phillips et al. say their study demonstrates that "the enhanced carbon flux from roots to soil in low fertility forests exposed to elevated CO2 creates hotspots for microbial activity that are associated with faster rates of soil organic matter turnover and N cycling," which phenomenon provides the trees the extra nitrogen they need to take full advantage of the enhanced potential for growth that is provided by atmospheric CO2 enrichment, thereby overcoming the incorrect implications of the progressive nitrogen limitation hypothesis. And to make this point perfectly clear, they state that their results "provide field-based empirical support suggesting that sustained growth responses of forests to elevated CO2 in low fertility soils are maintained by enhanced rates of microbial activity and N cycling fueled by inputs of root-derived carbon."
ExxonMobil ‘Linked to 9 of Top 10 Climate Skeptics’ · Environmental Management & Energy News · Environmental Leader
The Carbon Brief says its analysis is significant because it shows that climate skeptics constitute a small network of individuals, disputing skeptics’ assertion that there is significant scientific disagreement over the causes of climate change.

In a statement to Environmental Leader, ExxonMobil responded: “The post conveniently ignores the hundreds of millions of dollars we are investing in new technologies to reduce greenhouse gas emissions and manage the risk of climate change.
