Climatologist Dr. Judith Curry: ‘What we are seeing is natural climate variability dominating over human impact’
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.
Sun’s Current Solar Activity Cycle Is Weakest in a Century: ‘None of us alive have ever seen such a weak cycle’
SAN FRANCISCO — The sun’s current space-weather cycle is the most anemic in 100 years, scientists say.
Our star is now at “solar maximum,” the peak phase of its 11-year activity cycle. But this solar max is weak, and the overall current cycle, known as Solar Cycle 24, conjures up comparisons to the famously feeble Solar Cycle 14 in the early 1900s, researchers said.
“None of us alive have ever seen such a weak cycle. So we will learn something,” Leif Svalgaard of Stanford University told reporters here today (Dec. 11) at the annual meeting of the American Geophysical Union. [Solar Max: Amazing Sun Storm Photos of 2013]…
