As this Solar Cycle 24 winds down, there will be less EUV to warm the upper atmosphere/ozone layer. A simple check of this effect is the temperature of the regions around the South Pole. The Weather Underground gives “good” data. Look for new regional extremes and averages to drop in temperature. Possibly setting lots of new records. We have never been in a “cooling period” so global predictions have no historical statistical data.

The most interesting Pacific Ocean feature is at 45N, 130W. This 1600 km diameter warm water region [+2C] is still effecting the Jet Stream and the weather of the US.

See http://weather.unisys.com/surface/sst_an... . Cooling will not accelerate until this region cools to long term average or less.

The most interesting Atlantic Ocean feature is at 45N, 40W. The region of frigid water is -4.5C less than average. Since this is Arctic Current driven, it has the potential to affect the Gulf Stream. This can prevent the warm waters from flowing North and be defected more to the east. This result could be less ocean heat for England/Europe this Summer and next Winter.

I think the warming in the Movie was the warming that happened naturally which ended the last "ice age" and presumably resulted in the extinction of the Megafauna which was at least most of the cast.

Humanity must have built a time machine and sent all that CO2 back into the past to obliterate the climate in the movie.

Well they show volcanoes erupting, so perhaps thats what they are suggesting

Why do you ask?

Keep in mind that they don't want to waste time on "why" when they have a story to tell.

I didn't see it, but I doubt that CO2 is considered.

The easiest would be an asteroid hit.

That's quick and easy to understand, even if it's not particularly relevant.

You live in a fantasy would like most denialists
