Barbara, I hope you might forward my comments to your guest. I was only able to listen to part of today's program but I am very interested. I want to raise my concerns about two prevailing frames that arise on your show and throughout serious discussion of climate change that I believe do great damage to the efforts to raise the awareness of the public and help them understand the urgency needed when addressing this issue.
First is the frame that global warming is happening slowly and will continue to do so. I do not believe the facts support such an assertion and not only does no one know that warming will not suddenly serge forward it seems to be doing exactly that. A report out last week raised the projected temperature for the planet by the end of the century to 9F from 4F degrees. That means that we are going to hit 4F by---2040? Until recently no one imagined the arctic ice cap could melt in anything like our lifetimes but in fact it will and it may do so as soon as 2013! The problem with the frames that give people the impression that GW is a slow process is that it provides fauls comfort, "Oh, technology will fix it before it happens," or "It is not my problem." Neither one is the case but too many people still think that way. So please start using a different frame from "by the end of the century," or “future generations." Instead say "within our life times," and stress the urgency. After all it is much more accurate to say catastrophic climate change is happening right now.

The second frame is that one cannot attribute any given weather event to global warming. That is only partly true. In fact one might say that you cannot not attribute any given weather event to climate change such is the post-industrial influence on the pre-industrial trajectory of the climate---we have departed the Holocene and are in the Antropocene some scientist tell us. It is like a basketball launched toward a basket that gets tipped by one of the players. Its trajectory is for ever changed. I think it is more accurate to say that the weather everywhere and everyday has been influence to some degree by GW. This is important because the frame that one cannot tell if an event is caused by climate change is asking them not to believe there own "eyes," experiences, or impressions which are often very astute. For instance in Oklahoma where I grew up we used to have thunderstorms in April and the 100F days did not come until late July. This year they had wild fires near Oklahoma City in April and the temperatures have been in the hundreds throughout much of this June---that has increasingly become the trend and is consistent with climate change projections. Now Oklahomans should by all rights believe that what they are experiencing is in fact global warming. It may be noted that Inhofe is a Senator from Oklahoma and one of the most radical global warming deniers and obstructionist in government.
I have been keeping up with this issue for a long time now and am alarmed at the rapidity that things are taking place. I truly believe we are probably in for crop failures, water shortages, and mass migrations here in North America, in this country, within our lifetimes and whereas I think there is a fine line to be drawn to not panic or send people into despair I think scientist tend to be much too measured in their statements. It is as though there is smoke billowing out of the projection room and the scientists don’t want be caught dead yelling fire in a crowded theater because there is no "proof" that there is in fact a fire.
Scientist have long dismissed the near term risk of a methane/co2 release from the arctic or the ocean meanwhile there is growing indications that that is exactly what is happening. As a NASA scientist you should know that a huge methane release was detected on Mars a few years ago and that is within a much more static system than ours----that should give us pause!
The public needs to be prepared in case there is a sudden spike in methane from the Arctic so I hope in the future Barbara you will direct your discussions of climate change toward the rapidity of changes already taking place and the potential danger of being too complacent and smug about what we know and what we think we do or do not know. Thank you.
