The Hawaiian station goes back to 1958 and is the main site for the famous Keeling Curve that shows rising carbon dioxide levels from burning of coal, oil and natural gas that tracks with rising temperatures. Levels of carbon dioxide at Mauna Loa have increased 33% since 1958. *>>>>>>>>>>>>>>>>>>>

Or take a chill pill:


The rise in carbon dioxide over the end of the ice age was significant, from about 180 carbon dioxide molecules for every million in the atmosphere to 260, a measurement called parts per million or ppm, according to study author Jeremy Shakun.
THE BIG MELT

This increase took place over about 7,000 years, Shakun told a telephone news briefing. By contrast, the current level of atmospheric carbon dioxide is 392 ppm, a rise of about 100 ppm in the last century or two, he said.

“In this century, we’re probably going to be going up about 100 (ppm) more,” Shakun said, but added that Earth probably won’t feel the total impact from this carbon dioxide rise for centuries.

“The system has a lot of inertia to it,” he said. “To warm up the oceans takes quite a while, and we’ve also got ice sheets and you can’t melt an ice sheet in 100 years.”

But while carbon dioxide pushed temperatures up to accelerate the ice age’s end, that was not the initial cause. Instead, the big melt was first prompted by a periodic wobble in the Earth’s axis, the scientists said.

At some points in the wobble, the Northern Hemisphere leans slightly closer to the sun and this occurred at the beginning of the end of the Pleistocene, when ice sheets covered much of what is now North America and Europe.

That slight sun-ward tilt melted those northern ice sheets within a few hundred years, pushing global sea levels up by about 33 feet, or by more than the total melting of the ice covering Greenland now would do, said co-author Peter Clark of Oregon State University.

Greenland’s ice sheet covers most of the island, over 656,000 square miles (1.7 million square kilometers), three times the size of Texas. Summer melt of this ice sheet increased by 30 percent from 1979 through 2006, and reached a new record in 2007, according to the U.S. National Snow and Ice Data Center in Colorado.

Because ice sheets are made of compacted snow, they produce fresh water when they melt, and the gush of fresh water into the salty North Atlantic altered ocean chemistry enough to shut down the Atlantic Merdional Overturning Circulation, sometimes called the conveyor belt, which typically sends heat from the tropics northward, moderating northern Europe’s climate.

When the conveyor belt slowed or stopped, cool temperatures stayed in the north and warmth stayed in the south, letting the Antarctic get warmer. That warming trend may also have shifted the winds and melted sea ice, drawing carbon dioxide out of the deep ocean, where quantities of it are stored, Shakun said.

More recent studies have indicated that when atmospheric CO2 rises, plant life grows faster and larger, which results in greater carbon sequestration. Climate morons need to look up the word “homeostasis”.
