Well I'm going to take a different tact with this.
GoPackGo feels that perhaps scientists in general and climate scientists in particular rely too heavily upon computer models to reach their conclusions.
What we're talking about here is high-level statistics, almost all of which is done with computers nowadays. We use statistics to make predictions based on available data or to see patterns in data, draw inferences from data, etc.
It's not an exact science, it never will be, but it's best method we currently have for making predictions for all kinds of things that aren't tangible or things that cannot be practically measured to an exacting degree.
Statistics are used in every major industry and every scientific field, Exxon uses it to estimate sizes of oil wells for instance - and amazingly they revise their estimates up or down based on the latest data - climate science really isn't any different.
So it should come as a shock to no one that models are tweaked or predictions can change based on updated data - but what hasn't changed is the consensus that we are changing our climate.
The message that was being spread was that Global Warming was destroying the planet because increased CO2 levels caused by human waste. This has prompted billions in spending to make the planet greener.
Many of the people preaching this message were saying one thing yet doing another (Al Gore anyone??? Or how about the recent Climate change convention where the host city ran out of limos to tranport the attendents who arrived in private jets???)....
Then we come to find out that data used by some scientists for these 'predictions' was altered/ignored becuase it did not fit the warming trends they projected?
Now there are predictions (which is the subject of the OP) that we are going to have a 20-30 years cooling trend...so castrophic global change will really start after this cooling period ends??? or is the increased CO2 really not warming up the planet now as these scientists have projected??
Since I am not a scientist, I probably cannot dessimenate all of this information properly...However, I do have my own bullshit detector and I smell some serious bullshit here. This is how I see it in my layman's eyes...
