New research published in the journal Nature, suggests that the glacial melting in the Antarctic we've been reading about in recent news headlines has been going on for thousands of years.


Evidence for massive and abrupt iceberg calving in Antarctica dating back 19,000 to 9,000 years ago is based on an analysis of new, long deep sea sediment cores extracted from the region between the Falkland Islands and the Antarctic Peninsula.

You mean the earth isnt static? Im old enough to remember the global cooling drama from the 70s and they lost me after that as I thought there would never be a summer again. Its all fearmongering.

For God's Sake what are you doing???? Don't tell the "climate scientists" that! on't tell Kerry, Gore, and Obama! They want to keep calling you a 'flat earther' and suggest you be thrown in jail if you don't agree with the global warming agenda of levying taxes 'against carbon.' If stuff like this continues to appear in 'Nature,' of all places, a juried scientific journal of great prestige, they'll have to find some other 'facts' to bolster their agenda.

Or they can "hide the decline" again.

Don't forget the summary.

"A new study has found that the Antarctic Ice Sheet began melting about 5,000 years earlier than previously thought coming out of the last ice age -- and that shrinkage of the vast ice sheet accelerated during eight distinct episodes, causing rapid sea level rise."

I am somewhat perplexed by your description of the article. It doesn't represent the article's content faithfully.

Sea Ice is very different from ice on land. It's the ice on land melting which is causing problems. It also doesn't melt from the top down---if it did, it wouldn't be an immediate big deal. The problem is that the bottom melts (and is under pressure) and that lubricates the enormous mass of ice on land (glacier) above it into slipping into the ocean, where it will melt and raise sea levels.

There wasn't any 1970's scare from global cooling from actual scientists.

The Myth of the 1970s Global Cooling Scientific Consensus

Climate science as we know it today did not exist in the 1960s and 1970s. The integrated enterprise embodied in the Nobel Prizewinning work of the Intergovernmental Panel on Climate Change existed then as separate threads of research pursued by isolated groups of scientists. Atmospheric chemists and modelers grappled with the measurement of changes in carbon dioxide and atmospheric gases, and the changes in climate that might result. Meanwhile, geologists and paleoclimate researchers tried to understand when Earth slipped into and out of ice ages, and why. An enduring popular myth suggests that in the 1970s the climate science community was predicting “global cooling” and an “imminent” ice age, an observation frequently used by those who would undermine what climate scientists say today about the prospect of global warming. A review of the literature suggests that, on the contrary, greenhouse warming even then dominated scientists' thinking as being one of the most important forces shaping Earth's climate on human time scales. More importantly than showing the falsehood of the myth, this review describes how scientists of the time built the foundation on which the cohesive enterprise of modern climate science now rests.
