The UN models agree with established science that if human greenhouse gas emissions were causing global warming, there should be a hot spot of higher temperatures in the troposphere above the tropics, where collected concentrations would have the greatest effect, and the warming would show up first.
FORBES: Fakegate: The Obnoxious Fabrication of Global Warming
Does this cast doubt on the data which show warming at the earth's surface?
All three show warming of about the same magnitude.
FORBES: Keep This Bit of News On the QT: The Earth Is Round!!!
So if you happen to be doing an Internet search regarding global warming, you are likely to come under the impression that the latest and greatest crop data show global warming is decimating corn and wheat crops.
FORBES: Fortified By Global Warming, Crop Production Keeps Breaking Records
Warming up for the show that afternoon, I with my parents had gone on the NBC studio tour.
And while surface stations show slight warming for its Western Peninsula, temperatures over most of the continent have been stable or cooling since 1960.
Note that the warming before 1940 is attributable to the global recovery of temperatures from the Little Ice Age, and even the land based records show no warming over the last 13 years.
FORBES: Salvaging The Mythology Of Man-Caused Global Warming
They show that warming spells very like that of the past 100 years occurred repeatedly, long before the large-scale use of fossil fuels and the associated emissions of carbon dioxide gas were a possible factor.
Analyses of the Atlantic, Pacific and Indian oceans show a significant warming trend in tropical areas of the Northern Hemisphere, close to what is known as the thermal equator.
Although Greenland has recently been experiencing a slight warming trend, satellite measurements show that the ice cap has been accumulating snow growth at a rate of about 2.1 inches per year.
In order to justify government action against global warming, advocates must also show that the proposed action will substantially reduce the negative impacts of the asserted crisis and that the costs of such action will not outweigh the benefits.
FORBES: The Death Of Global Warming Skepticism, Or The Birth Of Straw Men?
Muller also confesses that one-third of land based temperature stations worldwide show cooling rather than warming.
FORBES: Salvaging The Mythology Of Man-Caused Global Warming
Instruments show there has been some warming of the Earth's surface since 1979, but the actual value is subject to large errors.

Weather stations, ocean measurements, decreases in snow cover, reductions in Arctic sea ice, longer growing seasons, balloon measurements, boreholes and satellites all show results consistent with the surface record of warming.

Alarmists claim global warming causes more droughts, yet objective, real-world data show drought frequency and severity is declining.
If you have thoughts on how to end global warming or comments about something else you've heard on our show, write us.
The alarmists make spectacular claims, supported merely by speculation and subjective predictions, that global warming is causing all sorts of horrible crises, while the objective data show exactly the opposite is happening in the real world.
Alarmists claim global warming causes more frequent and severe hurricanes, yet objective, real-world data show recent hurricane activity has fallen to record lows.
For example, according to all GCM simulations, increased CO2 concentrations should have produced an increased tropical warming trend with altitude, which is contrary to what balloon and satellites observations actually show.
FORBES: Global Warming? No, Natural, Predictable Climate Change
Durang flings all kinds of references into his word processor: Angelina Jolie, Snow White, Maggie Smith, global warming, Norma Desmond, William Penn, "Peter Pan, " the HBO show "Entourage, " Lindsay Lohan, ancient Greek drama, voodoo and, as the title suggests, a big dollop of Anton Chekhov.
In a study just published in Nature, the group's models show that, as temperatures rise, forests may emit more CO2, leading to greater warming.
But for now it is still a trial and Anne Jensen, like most Greenlanders, goes to great lengths to show that the people who live here do not want to get wealthy on the heels of global warming.
