This paper published at Nature Climate Change last year blows the AGW theory out of the water. CO2 never was a culprit, but does the opposite, causes greening.
Global environmental change is rapidly altering the dynamics of terrestrial vegetation, with consequences for the functioning of the Earth system and provision of ecosystem services1, 2. Yet how global vegetation is responding to the changing environment is not well established. Here we use three long-term satellite leaf area index (LAI) records and ten global ecosystem models to investigate four key drivers of LAI trends during 1982–2009. We show a persistent and widespread increase of growing season integrated LAI (greening) over 25% to 50% of the global vegetated area, whereas less than 4% of the globe shows decreasing LAI (browning). Factorial simulations with multiple global ecosystem models suggest that CO2 fertilization effects explain 70% of the observed greening trend, followed by nitrogen deposition (9%), climate change (8%) and land cover change (LCC) (4%). CO2 fertilization effects explain most of the greening trends in the tropics, whereas climate change resulted in greening of the high latitudes and the Tibetan Plateau. LCC contributed most to the regional greening observed in southeast China and the eastern United States. The regional effects of unexplained factors suggest that the next generation of ecosystem models will need to explore the impacts of forest demography, differences in regional management intensities for cropland and pastures, and other emerging productivity constraints such as phosphorus availability.
The greening of the environment is set to continue in the US without the destruction that the wind turbines are doing to the environment in so many ways. “The War on Coal” is over:
The Senate confirmed Scott Pruitt on Friday to run the Environmental Protection Agency. Vote was 52 to 46
Time to burn more coal, seeing that temperatures are crashing:
Since record highs caused last year by an ‘el Nino’ sea-warming event in the Pacific, HadCRUT 4 has fallen by more than half a degree Celsius, and its value for the world average temperature in January 2017 was about the same as January 1998.
Update, Senator Allen West nails it:
[…] These government employees must be fired.
They cannot operate in this realm of feeling “untouchable” any longer. Their paychecks are signed by us, the American taxpayer. They don’t work for any political party, cause, or in advancement of an ideology. They are part of the swamp, the bureaucratic administrative state, and there is no place more indicative of that than the IRS and the EPA. This agency in the past eight years was used as an ideological agenda weapon of mass destruction.
