Gavin Schmidt – Global Warming Exposed

Dr Gavin Schmidt is a climatologist and Director of the NASA Goddard Institute for Space Studies, one of the world’s top climate research organisations. He is only the third person to hold this post for NASA, having taken on the role from James Hansen – the “father of climate change awareness”.

Gavin’s work focuses on understanding past, present and future climate change and on the development and evaluation of climate models, and he has written over 120 publications that specialise in simulations of the past, present and future.

Scientific American cited him, as one of the 50 Research Leaders of 2004, and his 2014 TED talk on climate modelling has been viewed over one million times.

While Gavin proposes that climate models are skilful, he advocates that what’s most important is for us to “get off our carbon diet”.

Interesting interview. Thank you for sharing.

Stephen Briggs

The climate is changing and it of course always has been, CO2 levels have been increasing for several years which is hardly surprising considering mankinds recent advances in technology, industrialisation and population growth. What would be nice to know is how much further the CO2 level will rise if it even should given the current state of the World, the powers to be and the changes in technology. Will static emissions give us a plateau of this climate change or is it totally beyond our control and will change as it wants as has been the case for millennia?


is your site even up anymore? data doesnt seem to get thru to me?


is any things that can be done for those problems or we just die by only knowing it

Jez Brunatny

Stop worying about co2 levels start thinking about alien laser brain manipulations technics think about that they will force us to think i believe in that.


Thank you Brian for the presentation. Polished and informative. Your discussion with Dr. Schmidt provides for a teachable moment as it relates to the profound revelation of the lack of understanding and the misguided thinking associated with the Climate Change advocates of today. The interview exposed Dr. Schmidt’s fundamental misconception of the use and value of Computer Modeling. Any climatologist worth his salt including Dr. Schmidt will tell you that the climate and all the forces that act upon it, both large and small are far too complex to be completely understood yet alone modeled. Dr. Schmidt’s expressed his naive… Read more »
