Yes, it’s getting warmer.
PBS criticized for featuring a global warming denier with no scientific credibility
By Bob Berwyn
FRISCO — Public television is the the scapegoat in one of the latest climate capers, as the network’s popular NewsHour program recently broadcast a segment on global warming prominently featureing a fringe, self-described weather expert as a spokesman for the global warming denier movement. Watch the segment here.
The segment started harmlessly enough, with an interview of physicist Richard Muller, who recently claimed conversion from global warming denier status. The interview then whirled off into the realm of the surreal, with a lengthy one-on-one segment with non-scientists Anthony Watts, who publishes a blog that’s become a rallying point and last bastion of sorts for the small minority of Americans who still think global warming is a hoax and/or a conspiracy by scientists to get more research funding.

Ill-timed Earth Day letter on climate change debunked
Global March temperature anomalies.
*Editor’s note: This op-ed was written in response to letters to the editor in the Summit Daily News, published in Frisco, Colorado. The newspaper frequently publishes letters by Hertzberg that are full of scientific inaccuracies and misleading statements.
By Howard Hallman and Brad Piehl
Sunday was April 22 was Earth Day. The Summit Daily celebrated by printing a full page feature spread about climate change denier Marty Hertzberg. Marty has anointed himself as a climate change expert, but in fact he spent much of this career doing mine safety work for the coal industry. Given his background and apparent lack of research experience it is hard to see him as a fair minded credible expert on global warming.
Much of what Marty states as fact is naïve and untrue. The earth’s temperature has increased dramatically over the past 50 years, by all reasonable accounts the direct result of rapid population growth and a significant increase in carbon dioxide emissions into Earth’s atmosphere.
Contrary to Marty’s assertion, small increases in any number of substances including carbon dioxide and fluorocarbon derivatives do have a large and long-term impact on weather. In fact, that’s how cloud seeding works; a relatively tiny quantity of substance is blown into the air triggering the formation of ice crystals and subsequent snowfall.
The global warming controversy in the United States is not really a public policy discussion; rather it is one more political straw man for those who seek to generate hate and divide us. (more…)

The latest claim is that global warming ‘ended’ in 1997
Notice how even the coolest years aren't quite as cool as they were even just 20 years ago? The latest myth of global cooling is a classic case of cherry picking a short segment of the climate record to try and confuse and mislead the public.
By Bob Berwyn
SUMMIT COUNTY — The latest climate-change rumor floating around the web is that global warming has ended, to which we could all say Hallelujah and Amen, were it only true.
Not only that, but the perpetrators of the myth have actually identified a specific date for the end of that pernicious warming trend that is already causing so many problems around the world. Hanging their hat on a data set recently released by the UK Met Office, they claim that global temperatures have been cooling since 1997. (more…)

Can the Earth's atmosphere shed excess heat to space?
Opinion — The debate over a flawed paper serves global warming skeptics well since it creates the illusion of an overall climate science debate
By Bob Berwyn
SUMMIT COUNTY — The latest flap over climate science — and specifically about human-caused global warming — shows once again how ideological and political this issue has become, to the detriment of average citizens who are trying to understand what’s going on with greenhouse gases in the atmosphere.
A short timeline sets the scene: Earlier this summer, global warming skeptic Dr. Roy Spencer published a paper that discussed the role of clouds in the Earth’s climate system and purported to show how the Earth’s atmosphere was more efficient at releasing heat to outer space than previously believed. Last week, the editor of the journal that published the paper resigned after saying it was flawed. BBC news covered the story thoroughly.
Even though Spencer has a record of publishing research that’s been called into question by many other climate scientists, his July paper was pounced on by the few remaining media outlets that insist on pretending there’s still a legitimate debate about the fundamental physics of global warming. Fox News and Forbes, for example, trumpeted headlines suggesting that this one paper out of thousands somehow cast doubt on the entire body of climate science that’s been meticulously compiled and scrutinized again and again … and again.
