Global Warming Today: Climate Models Are Fault, Part 3,496

Climahysterics have been relying on computer models for decades to prove that Man is killing us all with warming,  much like they rely on the cute drawings with no factual proof to prove that the theory of Evolution is real. How’s that working out?

Computer analyses of global climate have consistently overstated warming in Antarctica, concludes new research by scientists at the National Center for Atmospheric Research (NCAR) and Ohio State University. The study can help scientists improve computer models and determine if Earth’s southernmost continent will warm significantly this century, a major research question because of Antarctica’s potential impact on global sea-level rise.

“We can now compare computer simulations with observations of actual climate trends in Antarctica,” says NCAR scientist Andrew Monaghan, the lead author of the study. “This is showing us that, over the past century, most of Antarctica has not undergone the fairly dramatic warming that has affected the rest of the globe. The challenges of studying climate in this remote environment make it difficult to say what the future holds for Antarctica’s climate.”

The problem with climate models is that they are trying to model an extremely interactive and intricate process which they do not fully understand. Water vapor and clouds are barely understood. Other forces of nature are unknown and unpredictable, such as volcano’s, tornado’s and their impact, tectonic forces, solar output, El Nino, tropical waves, etc. What is known is that weather – which is, essentially, natures way of moving cooler air and water to where it is warmer, and vice versa – in one area can effect the weather in another far away. If you are modelling one area, what is the weather in another doing?

Second, computer models are only as smart as the programmers and the data. If there is any bias in the system, if there is missing data, if there are unknown variables, then the output is incorrect. And, if you talk to actual scientists, you find that they must make decisions on which parts of the climate are more important than others, and they really do not know how all the pieces interact.
