Are you unable to use links when provided? I pointed you to the NOAA site that has ocean and land temperature readings for the entire globe from 1880 to today.

What do you mean by readings? Please be specific. Do you mean surface readings or satellite readings?
Why would I restrict myself to just those readings when there are balloon and ocean readings too.

I don't think you know very much about the alleged "global warming" when you complain about the data given by Crichton.
You challenged Crichton's figures. I challenge you to give answers to my questions.
Go take a math class then come back and try to argue. (This was answered earlier in this thread several times.) To find global temperature you have to take all global readings and average them. Simply using a FEW local temperatures does NOT give you global readings. Do you know how the stock market indicees work? They don't use only a couple of stocks from 2 points in time to decide what direction the market is going. It requires multiple stocks and graphs to point to trends. The same thing with global temperatures. You can't find anything based on only 2 readings. It shows no trends and the temperatures can be cherry picked. It's not that your questions weren't answered. You seem to be incapable of understanding the most basic answers and can't understand simple HS math.

I will give you something to chew on.
How much did you say the earth's temperature has increased over the past two decades?
You didn't> I'll tell you---0.05 C per decade in the lower atmosphere.
Nice misuse of the average again while ignoring trends. The earth has warmed .6 C in the last 120 years. That might AVERAGE out to .05 per decade but it isn't that in reality. The global land and sea surface data shows much of the warming has come more recently. The warming is speeding up. (More math for you to learn.) Over the last 2 decades the ACTUAL increase has been .19 C per decade. (NOAA website using GHCN-ERSST data set.) From 1880 to 1985 the earth warmed .03 C per decade.
Quote:Are computer simulations of the earth's climate accurate?
No
How many different simulations are there for global warming? Do you know? The last time I really looked into it, some of them modeled higher than observed, some modeled lower. The interesting part was the average of those models tended to show less warming than what was actually observed. Perhaps you need to go do some research before you attack the science.

Why? Scientists can calculate how much energy is added to the atmosphere by increases in greenhouse gases. Then, using sophisticated computer models, they attempt to simulate how the climate RESPONDS to the added energy. NO ONE KNOWS HOW TO CALCULATE CORRECTLY THE CLIMATE'S RESPONSE TO THE ADDED ENERGY.
Two of the many questions in this regard are the impacts of water vapor and clouds in the climate response. Scientists need to learn more about whether changes in atmospheric water vapor and clouds AMPLIFY OR DIMINISH the effects of human-made greenhouse gases on the earth's climate.
Yes, scientists do need to learn more. That is part of what science does. Always tries to find out more to verify or dispute what others think it does. The problem with your argument is you ASSUME that all the modeling is wrong on the HIGH end. A FALSE assumption on your part based on reality of the modeling.

You dismissed Crichton as a "novelist". However, I challenge you to show how he is mistaken when he says-
"Nobody knows how much of the present warming trend migh be a natural phenomenon"
and
"Nobodyy knows how much of the present warming trend might be man made"
Chew on those comments for a while, Parados.
Interesting.. NO ONE KNOWS yet you are saying what? that NONE of it comes from man made sources? Maybe YOU need to think about Crichton's comments. (Crichton takes a small part of science and uses it to create a fictional story. Should I believe that time travel exists because Crichton used some parts of string theory to claim it was possible in one of his books? Crichton like all fiction writers selects his facts to make his story seem real. He is free to ignore anything that would dispute his fictions. He is not doing science.)
I suggest you go read comments by Lindzen where he states pretty clearly that doubling CO2 will raise the earth's temperature by 1 C. Lindzen opposes Kyoto. Now.. care to find me one credible climatologist that says CO2 has NO effect on temperature? The Bush report on climatology says that CO2 will raise the temperature. I can't find one single report anywhere by a REAL climatologist with REAL credentials that claims otherwise. Perhaps you can find me one. (CO2 levels closely follow temperature based on ice cores.)
I love the part where you quoted someone claiming the sun was cooler 400 years ago. What science told them that? Was it measurements from space at that time? Do you have a reference to a scientific journal so I can check the science? Sorry Chic but when your basis for science is The Heritage foundation and a fiction writer, I don't see much reason to respond. But when you DEMAND I do, fine, I will gladly show you how little you really know. Are you going to tell us next that underwater volcanoes are heating the ocean?
