Making future predictions…

 

Basically get the biggest computer you can lay your hands on, account for as many variables as possible that are involved in climate feedback, such as solar variations, ice and snow albedo, water vapor and other blanket gases, ocean and land carbon sinks (use known equations or develop new ones and stick to basic laws of physics energy conservation, mass and momentum),  set the computer off and hey presto, three months later, many millions of calculations later, there is your climate model for the next 250 years. Simples!

Yes all this from the person who struggles with basic IT, never mind basic physics and maths.

However the people that are developing these complex models have tested them against what we do know from observable historic data, and conclude they are capable of projecting (not predicting) future patterns. Big difficulty is knowing precisely what is gong to…
