Approximately 130,000 – 110,000 years ago the Earth’s climate was pretty much the same as it is today. The Earth then entered the fourth inter-glacial to glacial period which ended about 10,000 years ago.
The period from the first to fourth glacial cycle lasted about 900,000 years. The slide into the last glacial period occurred very quickly geologically within less than 400 years. The Earth became drier, evaporated water became snow and polar ice caps expanded into ice sheets.
The furthest extent of these ice sheets formed the geology of Long Island, Block Island, Nantucket and Martha’s Vineyard. The ice in many cases was 1 mile thick.
We are currently exiting the last ice age which ended geologically 10,000 years ago into a period called the Holocene. The Earth is warming. Ice caps will melt. Species either will adapt or head into extinction.
The Earth’s climate takes very little notice of man’s activity on the planet. The average warming period can end rather abruptly geologically. To assume man is the primary driver of planetary climate is to believe in one’s own ego more so than Mother Nature which doesn’t give a whit who inhabits her. Just ask the dinosaurs.

“New Forests Company, grows forests in African countries with the purpose of selling credits from the carbon-dioxide its trees soak up to polluters abroad.”
I’ve never understood why tax credits are transferrable. If you’re looking to sell them, clearly you don’t need them, and selling them simply defeats the purpose.

The price is too high, eh? In that case, better to let your children pay it. That about right?

In the face of years of scientific findings and growing impacts, the doubters persist. They ignore long-term trends and seize on insignificant year-to-year blips in data to claim all is well. They focus on minor mistakes in thousands of pages of peer-reviewed studies to claim all is wrong. And they carom from one explanation to another for today’s warming Earth: jet contrails, sunspots, cosmic rays, natural cycles.
“Ninety-eight percent of the world’s climate scientists say it’s for real, and yet you still have deniers,” observed former U.S. Rep. Sherwood Boehlert, a New York Republican who chaired the House’s science committee.
Christiana Figueres, Costa Rican head of the U.N.’s post-Kyoto climate negotiations, finds it “very, very perplexing, this apparent allergy that there is in the United States. Why?”
The Australian scholar Hamilton sought to explain why in his 2010 book, “Requiem for a Species: Why We Resist the Truth About Climate Change.”
In an interview, he said he found a “transformation” from the 1990s and its industry-financed campaign, to an America where climate denial “has now become a marker of cultural identity in the `angry’ parts of the United States.”
“Climate denial has been incorporated in the broader movement of right-wing populism,” he said, a movement that has “a visceral loathing of environmentalism.”

Russ since you liberals and the Mad Hatter Gore started this mania about man-made climate change…prove it. I didn’t start it, and Gore certainly didn’t. However the following organizations had some influence… en.wikipedia.org/wiki/Scientific_opinion_on_climate_change I realize that for you folks this isn’t about pointing to scientific evidence or consensus or you’d already be convinced enough to take action. But there is something in your post I think I can correct. You’re confused about the nature of scientific theory. When you say “prove it,” you ask for an impossibility. Here’s Stephen Hawking from “A Brief History of Time”: A theory is a good theory if it satisfies two requirements. It must accurately describe a large class of observations on the basis of a model that contains only a few arbitrary elements, and it must make definite predictions about the results of future observations. For example, Aristotle believed Empedocles’s theory that everything was made out of four elements, earth, air, fire, and water. This was simple enough, but did not make any definite predictions. On the other hand, Newton’s theory of gravity was based on an even simpler model, in which bodies attracted each other with a force that was proportional to a quantity called their mass and inversely proportional to the square of the distance between them. Yet it predicts the motions of the sun, the moon, and the planets to a high degree of accuracy. Any physical theory is always provisional, in the sense that it is only a hypothesis: you can never prove it. No matter how many times the results of experiments agree with some theory, you can never be sure that the next time the result will not contradict the theory… a good theory is characterized by the fact that it makes a number of predictions that could… Read more »
