Why weather prediction got brilliant – but not climate predictions

So let’s have a look at why the weather predictions have got so much better in the last decades. - NOT A LOT OF PEOPLE KNOW THAT - Paul Homewood
There are four reasons, and we’re only going to concentrate on one.

• The first is that we have a better handle on the physics of the atmosphere...
• The second thing is we’ve got much bigger computers...
