An opposing view on ‘global warming’

-A A +A

By Evergreen resident Peter Link

Kevin Trenberth and I have known each other for about seven years. We disagree on global warming. We met again at the Foothills World Affairs Council meeting on Nov. 16, and though we shook hands in greeting, I was dismayed by his introduction of politics into his presentation, for which he used comic slides.

His slide presentation was littered with some truths, many half-truths and significant speculation. That the Arctic is warming is only half true since, in recent years, it has cooled, warmed, and warmed and cooled, etc.

Trenberth, who does not conduct his own temperature sequences, claims that temperatures are rising. Partly true, since they are declining and have fluctuated throughout the past and will continue to do so in the future. At least 14 global temperature satellites, continuously orbiting the Earth, have shown flat temperatures for 18 consecutive years ending Oct. 1, 2014, with slight cooling for the last several years. The declining temperatures are the most recent and correspond to diminishing solar cycles 23 and 24, which means less solar power to warm the Earth.

Even as CO2 has increased, there has been no warming. CO2 is a trace gas and amounts to about 0.04 percent of the atmosphere. Nitrogen and oxygen make up 80 and 20 percent of the atmosphere, respectively, and, with CO2, are necessary for life.

Claims that temperatures have risen come from physicist James Hansen of the Goddard Institute for Space Studies. He lowered archived early- and middle-20th-century temperatures and raised late-middle and late-century temperatures simply by reducing or increasing archived temperature values. This activity is canceled by the available satellite data. It is surprising that Trenberth would countenance such “science.”

The “97 percent” that Trenberth uses to tout believers of global warming was arrived at by collecting a group of believers and polling them. Observations and real data have countered such activity.

Charts and photos were selected to illustrate much as Trenberth performed along with political commentary. Trenberth says the planet is currently warming. Real data instead of speculation and politics deny that.

German economist Ottmar Edenhofer says: “One must say clearly that we distribute, de facto, the world’s wealth by climate policy.” He also says: “This has almost nothing to do with environmental policy.” Trenberth agrees.

But science does not agree!
