The Arctic Is Warming When It Should Be Cooling
In McClatchy the announcement of a new Study: Warming Arctic, after 1,900 years of cooling, isn’t natural
WASHINGTON — The Arctic was cooling for 1,900 years because of a natural change in Earth’s orbit until greenhouse gas accumulation from the use of fossil fuels reversed the trend in recent decades, according to a study published Thursday in Science magazine.
Scientists reconstructed the temperature record of the past 2,000 years using evidence from tree rings, ice cores and lake sediment, and found a steady cooling trend in Arctic summer temperatures of about 0.5 degrees Celsius — 0.9 degrees Fahrenheit — during the first 1,900 years. The cooling was caused by a slow natural cycle in Earth orbit that continues in this century.
“The summer cooling would likely be continuing today were it not for the increase of greenhouse gases from fossil fuel burning,” said David Schneider, a scientist at the National Center for Atmospheric Research and one of the authors of the study. “The results are important in showing that the dramatic changes happening today — and particularly the rapidity of the changes — are not natural.”
There is a 21,000 year cycle of change to the Earth’s temperature that is caused by the planet’s orbit. We are currently in the segment of the cycle that should be causing the planet to cool off, the segment that caused the Ice Ages. Not only are we not cooling, the temperatures in the Arctic are rising and have been for a while. It’s not just that we are warmer than “average”, the “average” should have been falling.

and i was just reading about antarctic rivers and lakes recently…
Even more water to raise the sea level.
Unfortunately not enough of it will become rain where it is need, and not enough of it is fresh.
Even some politicians are aware of these facts. Unfortunately, Sen. John Kerry never assumed the top job he very probably won (IMNSHO), so we’ll never know what U.S. policy on a number of environmental matters might have been with a more-or-less sane individual in the big chair.
If GeeDubya wanted to be Dog’s instrument in initiating the end times, he may well have succeeded. Time will tell… and not very much time, at that.
Consider how much “yogurt” we would be in if the trend wasn’t for cooling? That’s the really scary part.
By the time the majority of people understand that, yes, climate change will affect everyone, it will be past the window of time in which it can be reversed. We may already be at that point. Time to move (or stay) on higher ground.

The really bad part from this report is that things have been gradually adjusting to cooler temperatures for centuries, and now the direction has been reversed and accelerated for higher temperatures.
