 | | Article Details: Last year global levels of atmospheric CO2, the primary driver of global climate change, increased by 0.6 pct, or 19 billion tons. In addition methane rose by 27 million tons after nearly a decade with little or no increase. The burning of coal, oil, and gas, is the primary source of increasing CO2 emissions. Oceans, vegetation, and soils soak up half of these emissions. The rest stays in the air for centuries. | |

 | | Article Details: Eutrophication is a syndrome of ecosystem responses to human activities that fertilize water bodies with nitrogen (N) and phosphorus (P), often leading to changes in animal and plant populations and degradation of water and habitat quality. Nitrogen and phosphorus are essential components of structural proteins, enzymes, cell membranes, nucleic acids, and molecules that capture and utilize light and chemical energy to support life. | |

| | Quote Details: Most of the observed increase in globally-averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic GHG concentrations. It is likely there has been significant
anthropogenic warming over the past 50 years averaged over each continent (except Antarctica). IPCC 4th Assessment Report, Climate Change 2007 | |

 | | Article Details: For those that don't want to wade through pages and pages of the IPCC's 4th Assessment Report, this article in the UCCS website summarizes the key points. One of those points is that it is “very likely” that emissions of heat-trapping gases from human activities have caused “most of the observed increase in globally averaged temperatures since the mid-20th century.” | |

 | | Article Details: Much of Al Gore’s evidence lacks credibility. The presentation of the science is superficial, erroneous and misleading. CO2 is almost exhausted as an agent for greenhouse global warming. Water vapour is the primary greenhouse gas. The ocean and atmosphere circulations transfer excess heat from the tropics to the polar regions and so regulate surface temperatures over middle and high latitudes. And more... | |

 | | Article Details: The authors'analysis suggests that the global ocean has lost more than 90% of large predatory fishes. This is the first analysis to show general, pronounced declines of entire communities across widely varying ecosystems. The potential ecosystem effects of removing 90% of large predators from the open oceans is bound to be widespread, and possibly difficult to reverse. | |
