Climatologist Dr. Judith Curry: ‘What we are seeing is natural climate variability dominating over human impact’
Judith Curry, a climatologist at the Georgia Institute of Technology: 'All other things being equal, adding more greenhouse gases to the atmosphere will have a warming effect on the planet. However, all things are never equal, and what we are seeing is natural climate variability dominating over human impact.'
Curry: There is a 'growing realization that you can’t control climate by emissions reductions'
Flashback: Climate change is governed by hundreds of factors, or variables, not just CO2: UK Prof. Emeritus of Biogeography Philip Stott of the University of London: 'The fundamental point has always been this: climate change is governed by hundreds of factors, or variables, and the very idea that we can manage climate change predictably by understanding and manipulating at the margins one politically-selected factor (CO2), is as misguided as it gets.
Others have looked to natural climate systems for explanations for answers to the 15-year pause in global warming.
A study by Dr. Roy Spencer from the University of Alabama, Huntsville found that about half the warming that occurred since the 1970s can be attributed to El Niño weather events, which had a warming effect on the planet.
The Pacific Ocean’s natural warming and cooling cycles last about 30 years, with La Niña cooling being dominant from the 1950s to the 1970s and El Niño warming events dominating late 1970s to the late 1990s. Spencer suggests that the world may be in a La Niña cooling period.
