When it comes to Ice Ages.

       It turns out that most climate change deniers have been hinging their argument on the fact that in the history of the ice from the Antarctic Ice Sheet, covering the last Ice Age, the ending of that Ice Age began 800 years before the increase of carbon dioxide began to show up. So they assumed that it was the natural warming of the earth that caused the CO2 to show up. No proof, but it did make some sense.

       But now comes a new study that points out something that makes perfect sense. The way ice is made at the Antarctic, the arctic and places like Greenland and elsewhere, and especially during an Ice Age, is that snow falls. The snow traps air in it. Over time as snow continues to fall and snowpack builds, the pressure of the weight of snow compresses the earlier snow into ice.

       So what, you ask? Well in these recent tests, it has been proven that if snow falls on year one, that is the date of the air in the snow. But that snow doesn't become ice for hundreds of years. So when the ice is brand new, the air trapped in it is actually hundreds of years older, as much as 800 years or older.

       Now for some Global Warming deniers this will seal their argument and they may be convinced. Unfortunately, for many deniers of Global Warming, science or facts have no bearing on their opinions. These deniers don't like the idea of being told that they are causing a problem for our climate. They don't like being told that they are the cause of damaging out planet's ecosystem. Or that they're gonna have to change their ways and give up fossil fuels and the like.

       So they will cling to their belief that this science is bogus. That the entire scientific community is out to get them. And they're getting ready to arm themselves to protect their way of life. I think that arming themselves with boats may be a necessary weapon of self-preservation.
