Here is one scientist’s take:

Many of the comments to previous blogs have stated that models are “just” a set of assumptions, and that the processes in the Earth’s climate are so complex that they defy our attempts to model them with any rigor. There are assumptions that are made when models are built, but those assumptions are not simply pulled out of a bag of magic tricks. In fact, arbitrary, unjustified assumptions are generally repelled from the modeling community because, first and foremost, the models need to describe some set of observations and the evolution of those observations, i.e. prediction. Most components of models are, just like my original modeling efforts, a representation of mathematical equations that rigorously describe the motion of the atmosphere. The idea that I and my colleagues would work from some potpourri of unjustified assumptions is, in fact, a bit offensive.

Global Warming is dangerous, and alot can happen, such as the ice melting wich can cause floods or dangerous winds all kinds of stuff, pollution in air will be bad for our lungs, well die =(
theres more stuff about it. Hope it gave u a idea

Answer by odysseus1959
Make it so water is frozen or in a vapor form, we are in between., not AT one or the other. One must realize that there is no norm or set point, it changes, just as the continents move.

Question: One of the major limits to making better computer-based climate models is what?
One of the major limits to making better computer-based climate models is
1) faster computers.
2) more support for research on the use of technology to study climate.
3) collecting more data from existing research projects.
4) understanding global climate processes.

Answer:

Answer by Edesigner
1…no computers are plenty fast
2. throwing more money at the problem ,,wellllll
3. collecting more data from research projects,,this could be it but if your not familiar with 4. how the global climate processes take place then your out of the money…so I pick D….4…From the E…

Answer by david_bowman_sc
The fact is….our current models, as intricate as they are, fail miserably at predicting our current climates based upon the data of the past century. Because they cannot model our current climates using fairly accurate historical data, there is no way for them to model future climate changes or “global warming” because there is no accurate data. Models that pretend to predict the climate a century from now, try to use current conditions and “estimated” values of dozens of variables for the future.

As an example, clouds made of water vapor, both reflect sunlight back into space, trap heat in the atmosphere, and deliver water in the form of ice, snow, and rain. Without knowing how much cloud cover exists in say, 2025, and over what specific areas of the planet, we cannot tell what conditions will exist in 2030, 2035, or 2100. There are literally hundreds of variables that each climate model must account for in order to predict the general climate. Because of all these variables, it is impossible to estimate how the climate in a particular area, say western Europe, will change.

Forecasters are only now getting to the point (thanks to massive computing power) where an accurate forecast of the weather can be delivered for the following four or five days. Beyond that, chaotic elements limit forecasters to predicting as percentages of chance, or ranges of temperatures and precipication.

Question: Is this why the climate models always fail to predict the future?
The models are hind-cast to fit past climate data. Since this climate data has been altered the models are fundamentally flawed and therefore do not fit the REAL temperature curves going forward. It would make sense that the models don’t parallel observation.

That’s the problem when you “peer review” yourself. The extent to which they will go knows no bounds. They should re-hire Jim Salinger just so they can fire him again for the New Zealand climate record. Based on what they did to the NZ data, they have good reason to try to hide their data. It’s criminal.
