MATH ERROR: Scientists Admit ‘Mistakes’ Led To Alarming Results In Major Global Warming Study

by M. Bastasch, November 14, 2018 in WUWT/DailyCaller


  • Scientists behind a headline-grabbing climate study admitted they “really muffed” their paper.

  • Their study claimed to find 60 percent more warming in the oceans, but that was based on math errors.

  • The errors were initially spotted by scientist Nic Lewis, who called them “serious (but surely inadvertent) errors.”

The scientists behind a headline-grabbing global warming study did something that seems all too rare these days — they admitted to making mistakes and thanked the researcher, a global warming skeptic, who pointed them out.

“When we were confronted with his insight it became immediately clear there was an issue there,” study co-author Ralph Keeling told The San Diego Union-Tribune on Tuesday.

Their study, published in October, used a new method of measuring ocean heat uptake and found the oceans had absorbed 60 more heat than previously thought. Many news outlets relayed the findings, but independent scientist Nic Lewis quickly found problems with the study.

Keeling, a scientist at the Scripps Institution of Oceanography, owned up to the mistake and thanked Lewis for finding it. Keeling and his co-authors submitted a correction to the journal Nature. (RELATED: Headline-Grabbing Global Warming Study Suffers From A Major Math Error)

Why CO2 Is Not A Climate Control Knob

by A. Bright-Paul, October 22, 2018 in ClimateChageDispatch


As the Earth rotates on its own axis, one-half of the Earth is cooling while the other half is warming up.

So the Earth is warming and cooling daily and the temperature is changing 3,600 times every hour in every location all over the world, as there are 3,600 seconds in every hour.

As the Earth is traveling around the Sun in an ellipse at 66,000 miles per hour and is tilted and wobbling as it spins, so the Earth has seasons, as the angle to the Sun varies.

So the temperatures in the spring and summer are usually warmer than in the autumn and winter when temperatures decline.

So there is a massive number of different temperatures over the whole Earth, constantly changing and always in flux.

Wide-scale US wind power could cause significant warming

by James Temple, October 4, 2018 in MITTechnologyReview


Wind power is booming in the United States.

It’s expanded 35-fold since 2000 and now provides 8% of the nation’s electricity. The US Department of Energy expects wind turbine capacity to more than quadruple again by 2050.

But a new study by a pair of Harvard researchers finds that a high amount of wind power could mean more climate warming, at least regionally and in the immediate decades ahead. The paper raises serious questions about just how much the United States or other nations should look to wind power to clean up electricity systems.

Highlights

  • Wind power reduces emissions while causing climatic impacts such as warmer temperatures
  • Warming effect strongest at night when temperatures increase with height
  • Nighttime warming effect observed at 28 operational US wind farms
  • Wind’s warming can exceed avoided warming from reduced emissions for a century
