Since the 1960s, scientists have been on a money chase for grants from the Federal government. They do it for their own careers and because the universities want to put their snouts in the trough. Truth matters little; people publish what ever sells. The salesman's rule applies: Tell'em what they want to hear, sell'em what they want to buy." And the government bureaucrats want answers that give them more power.
The entire human-caused global warming campaign is a sordid example of this. It's a colossal fraud to get more money, jobs & tenure to whomever is a good liar for "the cause".
A reliable site and a very capable researcher finally obtained the raw, unadjusted data for ALL temperature stations in the world for ALL times that such exists. He analyzed it, looking very hard at that data's internal variability. That's what any GOOD researcher would do first: determine what that data's statistics can or cannot say about any trends. I learned this at MIT's Sloan School in the statistics class and in the forecasting from two fine professors. Look at the data!!!
What does one see from the raw data?
Here are two posts from a fine website written by a talented theoretical physicist (and talented number-cruncher), formerly of Harvard and now in his native Czech Republic.
"Those are just natural variations that Nature contains and everyone who wants to understand the climate and the weather should first learn something about the natural variability that the changing weather brings to various places of the globe - as well as their average."
There is nothing statistically significant in ANY of the claims about recent increases in global warming. The entire movement is an exercise in data-mining to support a political agenda ... and to get the money from the grants. The scientists pushing these claims are just like patent medicine hawkers - willing to say anything to get the money.
Whatever trends exist after normal variability is eliminated are the century + changes caused by changed in the Sun's activity levels over many decades or centuries.
All the models are wrong and the billions wasted on that has been flushed down the toilet. Carbon dioxide is an effect, not a cause: Image a bobber on a fishing line in a lake. It will move with the current and small waves, but the bobber does not cause the movement.
The cause of long term temperature variations on the earth is small changes in cloud cover (intrinsically water vapor) in turn caused by changes in cloud formation processes caused by changes in cosmic rays hitting the earth, which in turn are modulated by the solar wind and magnetic field, which are directly connected to solar activity levels in the active regions of the Sun. Yes, that's a long chain, but nature is full of long chains; in fact, all nature IS a long chain of connected actions.
Measurement of the carbon 14 isotope on the earth exist covering about 50,000 years. The carbon 14 level is strongly correlated with many measures of temperature. And carbon 14 IS created by cosmic rays. Why are these two measurement strongly correlated? BECAUSE THE SAME THING IS CAUSING BOTH, NAMELY THE COSMIC RAY CHANGES CAUSED BY SOLAR ACTIVITY CHANGES.
What we have is a physical process of causation AND measured data showing the effects exists. That is scientific PROOF and is TRUTH.
Word of the Day
Today there are two.
"Warp" - noun [$10] as used in weaving
Warp means the threads strtched lengthwise in a loom to be crossed by a weft.
"Weft" - noun [$10]
Weft means 1. a. the threads woven across a warp to make a fabric; 1. b. yarn for these; 1. c. a thing woven; 2. filing strips in basket weaving.
Sentence: Just as one needs both warp and weft to make woven cloth, so does one need both a physical process and data correlation to prove a scientific claim.
