Climate change deniers should check facts

Editor, the Advocate:

Regarding the recent letter to the editor June 4 in which the writer made statements concerning global warming:

The letter writer failed to cite any authorities for his assertions, but I suspect it to be Fox News - which my wife fairly accurately calls Faux News.

Among other misstatements, he wrote, "the Earth hasn't warmed in more than 17 years and has in fact cooled."

Here's what says:

"The year 2013 ties with 2003 as the fourth warmest year globally since records began in 1880. This marks the 37th consecutive year . the yearly global temperature was above average. Currently, the warmest year on record is 2010. Including 2013, nine of the 10 warmest years in the 134-year period of record have occurred in the 21st century."

So nine of the warmest years on record have occurred in the last 13 years. Hardly a cooling trend.

As to Weise's suggestion we burn natural gas instead of gasoline, that would be an improvement, but burning natural gas still produces carbon dioxide. Burning natural gas doesn't reduce our carbon footprint.

Polar bears? At the IUCN Polar Bear Specialist Group 2013 meeting, scientists reported on the 19 subpopulations of polar bears: four are declining, five are stable, one is increasing and nine have insufficient data. So, of the 10 populations for which we have adequate data, 40 percent are in decline, 50 percent are stable, and 10 percent are increasing. I'm sure the letter writer was citing that last population, but overall, polar bears are in trouble.

Ice caps? The letter writer says, "ice is increasing." But the National Snow and Ice Data Center says: "satellite data reveals that, since 1979, winter Arctic ice extent has decreased about 3 to 4 percent per decade. Antarctic ice extent is increasing, but the trend is small."

It's significant that extent isn't the right measurement. It's the amount of ice that is important. I suggest reading the May 19 report, "Esa's Cryosat mission sees Antarctic ice losses double." Overall, the loss of ice worldwide has been significant.

The letter writer shouldn't listen to propaganda from the right without doing some fact checking.
