It's funny how there is a global trend of warming, yet Edufer so adamantly denies it.
It is funny how I have never denied there was a warming, but Roman so adamantly accuses me of saying things I never did. Had you read one of my post in this same page, you would have kept silent. I will quote it for you again:<dir>Please get this right: I am not saying that Earth has not warmed since 1860, as it did warm until recently. The warming was totally natural because it was recovering from an abnormal cold period caused by the occurrence of three “double solar minima” (Maunder, Spoerer and Dalton).</dir>
Trends, as anything on this Earth, never stays too long in the same direction. Earth's climatic history says so. As I explained way up above, there was a warming trend as the result of a rebound from cld temps during the Little ice Age. We were heading to temperatures in the same range as those just before the Little ice Age, that is, the Medieval Warm Priod, sometimes called by climatologists (before the global warming hype) as the Little Climatic Optimum. Then came the IPCC and said those temperatures would be catastrophic.
But now the warming trend seems to have stopped and a new cooling trend has started, as shown by satellite and radiosonde baloons readings. There is no arguing about this. There was a warming - now the word is cooling. For how long? Nobody knows. Wen will the cooling be at its peak? About the year 2030, whith the onset of the Double Gleissberg Solar Minimum.
Will it really happen? Nobody can tell for sure, as no one can tell for sure there will be a catastrophic warming in the future. But if the Earth warms another 2º C, then we'll be having the same temperatures of the Medieval Warm period, or the Roman period of 500 before Christ - with no catastrophic effect on Earth. It is written down in history. No guesses here. Ancient records. That's all.
Would you care to check the cooling trend in many states of the US since 1900 to 2000? See here: <a href=http://mitosyfraudes.8k.com/Calen4/Ghostbusting.html>Temperature Trends in the US - 1900-2000</a>
Check cooling trend in Alabama (-1,17º F), Arkansas (-0,633º F), Georgia (-1.23º F), Illinis (-0.21º F), Indiana (-0.22º F), Kentucky (-0.04º F), Louisiana (-0.28º F), Mississippi (-1.09º F), Missouri (-0.804º F), North Carolina (-0.71º F), and other states show very little warming since 1900, in the range of 0.2º F to 0.9º F for a 100 year period!
But when the trend is calculated since the 1950s or 1960s onwards, the trend is mostly cooling. Don't take my word for it. Just check it for yourself. You can make your own trends: select starting year, ending year, mean temps, maximums, or minimums, even rain trends. Go to the <a href= http://www.co2science.org/ushcn/ushcn.htm>U.S. Historical Climatology Network</a> data base and make your own calculations.
You are up to a surprise.
