I don't know what the future holds but thinking Arizona will become unsafe in 10-15 due to climate change is a little foolish.
> This distinction can be made because a serious review of the literature shows that there was no such “scientific verity”. There are anecdotes that can be plucked from the record, primarily from the popular media. But a rigorous review by Tom Peterson and William Connolley (with some minor help from myself) shows that, even as the planet was in a short term cooling trend in the 1970s, concerns about greenhouse warming dominated the scientific literature. The paper documenting our results has been accepted for publication in the Bulletin of the American Meteorological Society, and Doyle Rice did a nice job summarizing the paper last week in USA Today.2
From http://www.inkstain.net/fleck/2008/02/global-cooling-the-und... but there are lots of places where you can find the "we once worried about global cooling" myth debunked.
Have you look at any actual data? Have you seen the trends in the data that have been going in the wrong direction? At the end of the day, unless the direction changes, it does not matter if it happens in 10 or 15 years or may take longer. It will happen.
I have a book from the 70s that talks about the up coming ice age with data to back up his claim.
Have I seen trends going in the wrong direction? It depends on what trends and what start point you pick. Currently things are trending lower than a few years ago as carbon output is being reduced in many countries. I remember when the target was keeping it under 3% degrees than lower than 2% now it sits at 1 1/2%. Soon it will be 1% global temp increase. So things do seem to be trending in the right direction.
