[Jeffrey Crenshaw]

Like what?

[Alan B]

So many assumptions in your presentation! Urgh..

[Alan B]

Pure speculation. 

[The Realistic Nihilist]

You should put all your global warming stuff into it's own playlist for convenience.

[Gaan Guano]

Does anybody have a link to somewhere I can watch the Inconvenient Truth online free?

[bcsviewer1]

I guess you missed this line: "The university claims that consistent reductions in cloud height could potentially lead to more efficient cooling of the planet, thus reducing Earth’s surface temperature and maybe even slowing down the effects of global warming." This is what is expected in the Iris Effect!

[Aanthanur DC]

they are not talking about the iris hypothesis there....

[bcsviewer1]

Actually, It states that more research is needed to verify the claim! Let's remember that from time to time, It takes a while to verify theories.

[Aanthanur DC]

so? doesn't Change the fact that the Iris hypothesis was and remains falsified.

[bcsviewer1]

Roger Davies from University of Auckland the lead researcher on study of cloud levels over the last 10 years claims the cloud levels have been lowering, but it's not know why or if it can allow for more efficient cooling. They said that it's too short a time period. See article (Falling Clouds May Combat Global Warming, 22 February 2012, redorbit.comp/news/science/111­2479879/falling-clouds-may-com­bat-global-warming/)
