If a model can correctly predict trends from a starting point somewhere in the past, we could expect it to predict with reasonable certainty what might happen in the future.
So all models are first tested in a process called .
The models used to predict future global warming can accurately map past climate changes.
If they get the past right, there is no reason to think their predictions would be wrong.
This is clearly a very complex task, so models are built to estimate are weather, averaged out over time - usually 30 years.
I trust it answers your questions (as much as it is possible to do so with As I see it,just about all the churches in North America are heated either oil or natural gas which has been found by companies using evolutionary concepts.
