A new study of NASA satellite data.
Blowing theories about climate change -- facts right out of well run out of the atmosphere NASA's data shows the future effects of global warming.
Could be far less than what most computer models to this point have predicted.
Joining me now the co author of that new study doctor Roy Spencer.
Spencer is a principal research scientist at the University of Alabama.
Formerly senior scientist for climate studies at NASA author of a number of books including the great global warming blunder.
I'll mother nature -- the world's top climate scientist great to have you -- this.
Let me ask you this is as I senator I understand it basically.
You're talking about real -- of the others are projections and possibilities conjured by.
Computers.
There's no contest it would seem to be than between that your results.
Well you've got to compare what.
Data can tell you vs what theory can tell you right so you're right date ultimately we -- explain the data right the trouble is we need models also in order to figure out what the data are telling us like I I like to tell people.
Making the measurements is the easy part figuring out what the measurements are telling us about cause and effect that's the hard part what well let's start with I I'm going to do this and inverse order we met.
What is then be a fact.
Of some climate change.
And right now what did you discover in your study is succeed please you could put.
Well we use ten years of the best NASA satellite data we have and what we did was we looked at warm years vs cold -- And during -- years we found that clouds change in such a way.
To reduce.
The amount of warming.
And what's interesting is that's totally opposite of all the climate models hear about that are forecasting global warming.
Because those models all change clouds in such a way to amplify the warning.
Sort of -- -- disconnect between.
Yes I area and I apologize torments for the delay here and I and I apologize to -- -- -- doctor Spencer.
But the so if we take a amplification.
And the reduction -- revealed instead in Europe our data -- research.
What is the what is the percentage effect on the conclusions.
About the environment in the impact.
A global change.
Right well the and well United Nations official forecast to -- the United Nations official forecast for the next let's say a hundred years.
Is a total of about three degrees C of warming.
And what we're finding from the real satellite data of how the real climate system.
Operates that it might be more like one degrees C of warming and maybe even less.
If that's the case then we've gone from global warming being a serious problem.
To global warming being -- you know some people will think it's not worth worrying about because who know isn't and another fifty -- -- hundred years.
We may not be realigned that much on fossil fuels anymore anyway.
And there's no question about climate.
Change for terrorism issue about is the effect of it primarily.
And really not much of a discussion about calls either.
Doctor Roy Spencer I hope you'll come back exactly.
Thank walk -- walking.
Doctor Roy Spencer we thank you for being with us or your comebacks and we can continue to take a look at what is happening to this -- planet of -- thank you -- good good to talk to him.
