Climate oscillations were just illusions, scientists say (only 11.12 years left)

Jan. 3 (UPI) -- There is only one confirmed climate oscillation, the El Niño/Southern Oscillation, or ENSO, according to a new study.

Analysis by a team of meteorologists suggest another pair of atmospheric patterns, the Atlantic Multidecadal Oscillation and the Pacific Decadal Oscillation, or AMO and PDO, aren't real.

Scientists previously estimated that the AMO and PDO patterns, like ENSO, were defined by shifts in warming and cooling. But the latest research, published Friday in the journal Nature Communications, suggests these shifts in temperature -- mistaken as climate oscillations -- are best explained by human activities and natural variability.

"Our analysis throws cold water -- forgive the pun -- on the idea, advanced by some climate change contrarians, that certain aspects of climate change," study author Michael Mann, a climatologist and geophysicist at Pennsylvania State University, told UPI in an email. "For example, the increase in recent decades in North Atlantic hurricane activity can be dismissed as a part of a natural internal climate cycle."

Unfortunately, the latest findings mean climate modelers can't rely on the AMO or PDO patterns to help them predict climate shifts across smaller scales.

Here is the next to last paragraph:

“In the 1950s, ‘60s and ‘70s, a buildup of sulfur aerosol pollutants in the atmosphere, caused primarily by coal power plants, had a cooling effect on Earth’s atmosphere. In the 1970s, the Clean Air Act and other regulatory measures helped curb sulfur aerosol pollution. As a result, the influence of greenhouse gas emissions reasserted itself, and global warming began to accelerate.”

To me, it has the writer stating that by ‘polluting’ the atmosphere we were causing global cooling, and now, thanks to environmental controls, we are causing global warming.

Talk about having it both ways that only man affects the climate.

You really would think they’d be embarrassed to publish such complete and obvious garbage.

“I’m waiting to hear Joe Bastardi of WeatherBell.com respond to this.l

Me, too. If I’m not mistaken he uses these phenomena pretty extensively in his predictions.

The search for oscillations means that scientists could believe in something predictable, which is what science is all about: given X/Y will equal Z. Fifty years ago I was taught that earth is a dynamic planet with the sun being the most dominant influence on earth. The quest for science is to predict the future of events on earth. Studying atmospheric composition at any given time is just one aspect of all of the elements that influence our climate from one year to the next.

When the data contradict the models, the data MUST be wrong. /s

I hear certain parts of the Middle East, specifically near the Baghdad Airport, had a sudden burst of warming which were caused by Donald Trump.

And major oscillations!

Oh, just give the UN your country, freedom and personal assets so they can turn the earth’s temperature down. If we fail, they threaten to turn it up. Although I like warm weather it’s because I’m a racist whitey and we all know that people of color are snow bunnies.
