I blame G W Bush!

The study reaffirms that changes in the amount of summer sunlight striking northern high latitudes sets the process in motion.

HA! They are asking us to believe that the sun actually has some sort of impact on our weather??? Everyone knows this is not the case. The only thing that ever affects the weather is man's release of CO₂

Ice ages: Why North America is key to their coming and going

The solution to the problem is obvious: destroy North America, or at least, Canada. ;)

...changes in Earth's orbit.

Really?

They need to add increased volcanic activity, and its related effects, into their simulations. They might be surprised how much effect that alone would have.

Canada’s fault.

While carbon dioxide decreased as the ice sheet expanded and cooled the climate and increased again as the climate warmed, CO2 levels did not determine the overall sequence of events during each 100,000-year cycle, the researchers concluded.

Paging Algore. Paging Algore. Please pick up the white phone in the lobby.

I found the article to be a bit confusing. Are the changes in orbit because of the weight of the ice sheet, or does the ice sheet just melt faster due to the changes in orbit, aided by its gargantuan weight?

Other than that, the climate warmed all by itself? No man made intervention??? Shocking!

The rain forests cause more CO2 than North American continent.

This whole theory and the article has to be untrue.

Everyone knows that all climate change is caused by humans and most importantly by the actions of George Bush during his 8 years in office.

He is a genocidal maniac and will be responsible for the death of untold millions and the ruination of miles of seashore estates of the rich and famous unless we immediately listen to ALGORE and the OBAMABOTS
