Bob... where in the reporce are you seeing +.44-.66? I'm not seeing it... Your first source is tropospheric... i want to confirm the second is tropospheric as well? ... Thanks..

Section 1.0.3 says +0.2-0.5C per decade, which is +.44-1.1C. +.66C would've been average of forecast.
They're talking about "Global mean surface air temperature". Not exactly sure what that means other than that it's part of the troposphere.

I think they are referring to global average surface temp... I'm not sure how exactly all the measurements differe, but the EPA does note a difference between surface, tropospheric and stratospheric change... meaning that comparing the two, the prediction for surface to the real of tropospheric, is problematic... epa.gov/climatechange/science/recenttc.html#tropospheric |

I'm reading closer to +.3C, but yes, under .4+ ... still consistent upward trend...

If you compare 1990 to 2011 it's actually less than +0.2C.

And if you go 1989 to 2010, then you have actually more than +0.4... The 5 year averages are better...

according to the long range chart, it is about 1.8F in 150 years, or about 1 degree F every 8 decades.

We can guess all we want but we really have no idea what is the cause and effect of the temp fluctuations in the earths surface. There are historical records that the south pole was once ice free. Must have been real hot back then. No power plants or automobiles then.

Must have been real hot back then. No power plants or automobiles then. no, we don't know why. that is true. we can make educated guesses, but that is all they are. and then, after making those educated guesses, we can weigh the probability of them, and the possible outcomes, and come up with a range of options of what to do from nothing to everything we can. |

We may not know all the causes but in the meantime why should we keep polluting our own environment? We keep putting more & more pollutants into our air, water & soil until we will finally kill off our species ! But most likely not in my life time. |

It is not about polluting the environment, it is about stopping the wasting of 100s of billions in govt(tax payer) money being pumped into wind, solar, etc, energy boondoggles...such as Solyndra and ENER1, and other companies with no chance of even remote success.

Except for CO2, which isn't even pollution to begin with, we've done a pretty darn good job of reducing pollution even as consumption has risen.

Exactly. Even if there is a problem, there's never been a single instance in all of human history of a government solving a problem with a top-down, command-and-control, central bureaucracy approach. |

Did you see the new data about the loss of ice in the last decade from the GRACE project? It's interesting. Basically there was no loss of ice in the Himalayas over the last decade, although all the ice there was predicted to be gone by 2035. About 385 tons of ice disappeared annually from Antartica and Greenland. The sea rose about 4/10ths of a millimeter every year of the study. GRACE is a NASA satellite.
People are interpreting the data all sorts of ways.
