Those who warn about global warming want us to look at the big picture... 100 years... statistically [or otherwise] modified weather histories... polar bears on ice floes.
I suspect that is because the big picture hides the reality of how much chaos there is in what makes up our weather and how earth's weather/climate systems are really not understood.As a local example, yesterday I looked at the weather forecast for a little more than a week from two well-know sources: The Weather Channel and AccuWeather.com.
See the problem when you can't even get agreement on a 9-day trend?
All right, I'll grant you that it is a forecast for Michigan in November, so a variance of 15° in forecasts for a week ahead is probably within acceptable parameters.
But when a lot of money is riding on being able to tell what's going to happen in the future, 15° is really outside of acceptable limits... especially when people are arguing about 0.6° climate change over the course of a century.
Well, it may be hard to tell where you are going when you don't have good information about where you are.
