ENVIRONMENTALISM: Peer-Reviewed Study Rocks Climate Debate!

Peer-Reviewed Study Rocks Climate Debate! 'Nature not man responsible for recent global warming...little or none of late 20th century warming and cooling can be attributed to humans'
Nature not man responsible for recent global warming

Three Australasian researchers have shown that natural forces are the dominant influence on climate, in a study just published in the highly-regarded Journal of Geophysical Research. According to this study little or none of the late 20th century global warming and cooling can be attributed to human activity.

The research, by Chris de Freitas, a climate scientist at the University of Auckland in New Zealand, John McLean (Melbourne) and Bob Carter (James Cook University), finds that the El Niño-Southern Oscillation (ENSO) is a key indicator of global atmospheric temperatures seven months later. As an additional influence, intermittent volcanic activity injects cooling aerosols into the atmosphere and produces significant cooling.

"The surge in global temperatures since 1977 can be attributed to a 1976 climate shift in the Pacific Ocean that made warming El Niño conditions more likely than they were over the previous 30 years and cooling La Niña conditions less likely" says corresponding author de Freitas.

"We have shown that internal global climate-system variability accounts for at least 80% of the observed global climate variation over the past half-century. It may even be more if the period of influence of major volcanoes can be more clearly identified and the corresponding data excluded from the analysis.”

Now THAT'S an inconvenient fact algore won't like.

But there is no debate about Anthropomorhic Global Climate Change.  They were right, the debate is settled, man has very little effect on the climate.

Ya know....

I've been asking this question for a long time now and I never get a reasonable response from those that believe in man-made global warming.

Q:  If man is responsible for global warming on earth, why is the temperature on Mars going up too?

That little rover is solar powered, so it has a carbon foot print of about zero.

I am waiting for someone to tell me the global mean temperature of Earth.

For the love of God. Earth's climate always changes NO MATTER WHAT. You can't change it. We are POWERLESS about it. Earth's climate changes for many reasons from volcanoes, current shifts, atmospheric change, solar patterns, and continental drifts.

Now how are liberals gonna keep raising taxes with talk like that?
