Paul M. Craig: Global warming has been going on for 22,000 years

To the editor:

Of course the Earth is warming. It has been warming for 22,000 years ever since the last great Ice Age peaked. By 12,000 years ago the area where most of us are reading this newspaper melted out from under the ice sheet that covered northern North America. Global warming, that is, made our lives possible.

Remnants of that ice sheet remain in the glaciers of Montana, Canada and Alaska and in the Greenland and polar ice caps.

Global warming will continue to melt this ice no matter what political decisions we make in futile attempts to stop it. The Earth will likely continue to warm until the climate of Anchorage, Alaska, is again like that of San Diego, California, as it was eons ago.

Anything we are doing today, or have been doing for the past 200 years, cannot possibly have caused a natural process that began 22,000 years ago. Global warming is caused by geological forces within the Earth, and by radiation from the Sun and from space beyond our solar system.

But we do know, and have known for at least 40 years, that emissions from coal burning power plants do foul our atmosphere and intensify global warming.

Thus, President Obama is on the right track in seeking further limits on carbon dioxide emissions. But his efforts must be couched in terms of pollution we can see and correct, not in terms of very real but mostly nebulous global warming that will continue for many, many millennia.

First, you've got to understand what consensus theory means. 2nd, far from denying global warming, I pointed out the scientific data that say the Earth has been warming for 22K years. And, most likely, it will keep on warming but for how long we don't have any real way to compute. Alaska was as warm as today's San Diego 50M years ago. Has global warming stopped? It has in the past, then picked up again. There was a mini ice age about 800 years ago. Lasted about 2 centuries Bottom line: our Sun, G2V, a yellow dwarf, will evolve into a red giant and either suck the Earth into it or push Earth into gelid space. Fortunately, the politicians don't have to bother us with their ideas about the cosmological evolution of the end of the Earth. Keep thinking, that's what science is all about. Regards, pmc

With 50% of the U.S. experiencing drought: in some cases desertification; with agribusiness ruining soil for food production by over-farming; and with technology that destroys drinking water for human consumption using billions of gallons of water per well, and pouring ruined water into aquifers, or destroying acquifers themselves, climate change is only one concern. Water is being commodified globally. We have abundant water in our region, but only so long as investment interests are kept out of our protected lands. We have a group of gas investment interests converging on all of our aquifers, attempting to locate pipelines and suss out whatever resources are available in Massachusetts. We have some of the best water and soil in the nation. Those are our resources. The next commodity, after they plunder the Marcellus, will be water: its already happening in other places around the U.S. and around the world.

Earth as seen in the Universe.... your words are seen in the Gazette for us to read and ponder. TAZ

This piece contends that the notion of anthropogenic global warming is sophistry by employing sophistry. The author should cite to the specifics of the science that is supported by the overwhelming consensus of the scientific community if he wishes disabuse us of the notion of a causal link of human behavior and global warming. Failing to address the actual science that supports human-caused global warming is something that climate change deniers have in common. Maybe that is because none of them understand it. Perhaps denying the science of global warming is nothing more than "political chicanery".

Maybe we are still rattled by the doomsday ice age predictions in the 70's followed by the massive ozone craze. Are we warming or changing again? I forgot.
