No graphs and no rebuttal, since there is none and none is necessary. Just statements and illustrations. Sea ice surrounding Antarctica reached a new record high extent this year, covering more of the southern oceans than it has since scientists began a long-term satellite record to map sea ice extent in the late 1970s. The upward trend in the Antarctic, however, is only about a third of the magnitude of the rapid loss of sea ice in the Arctic Ocean. The new Antarctic sea ice record reflects the diversity and complexity of Earth’s environments, said NASA researchers. Claire Parkinson, a senior scientist at NASA’s Goddard Space Flight Center, has referred to changes in sea ice coverage as a microcosm of global climate change. Just as the temperatures in some regions of the planet are colder than average, even in our warming world, Antarctic sea ice has been increasing and bucking the overall trend of ice loss. “The planet as a whole is doing what was expected in terms of warming. Sea ice as a whole is decreasing as expected, but just like with global warming, not every location with sea ice will have a downward trend in ice extent,” Parkinson said. Since the late 1970s, the Arctic has lost an average of 20,800 square miles (53,900 square kilometers) of ice a year; the Antarctic has gained an average of 7,300 square miles (18,900 sq km). On Sept. 19 this year, for the first time ever since 1979, Antarctic sea ice extent exceeded 7.72 million square miles (20 million square kilometers), according to the National Snow and Ice Data Center. The ice extent stayed above this benchmark extent for several days. The average maximum extent between 1981 and 2010 was 7.23 million square miles (18.72 million square kilometers). The single-day maximum extent this year was reached on Sept. 20, according to NSIDC data, when the sea ice covered 7.78 million square miles (20.14 million square kilometers). This year's five-day average maximum was reached on Sept. 22, when sea ice covered 7.76 million square miles (20.11 million square kilometers), according to NSIDC.

SHOCK STUDY: Carbon dioxide emissions help rainforests GROW FASTER... Tropical forests are growing faster than scientists thought due to rising levels of carbon dioxide in the atmosphere. A Nasa-led study has found that tropical forests are absorbing 1.5 billion tons of carbon dioxide every year as they photosynthesise and grow. And this is far more than is absorbed by the vast areas of boreal forest that encircle the Arctic. The researchers claim their findings show that rainforests like the Amazon are essential for soaking up excess greenhouse gases, and play a far greater role than had been previously realised. Read more: www.dailymail.co.uk/sciencetech/article-2891432/Carbon-dioxide-emissions-help-tropical-rainforests-grow-faster-Study-shows-trees-absorb-greenhouse-gas-expected.html#ixzz3NaGqPq1hFor years the "concensus" according to the propeller-beanied ones was that rain forests (jungles) emitted as much or more CO2 than they took in. The NASA and other source data shows that as CO2 levels rise so does plant growth. I think the same will be "found" in the oceans and lakes where both microscopic and macroscopic aquatic plant life depends on CO2 produced by sea animals and absorbed from the atmosphere.

No,no shock. none whatsoever.
It's science, Old Sailor. It reserves the right to come up with new information as things change or new things become known about a subject. And it doesn't answer to politics, as some people who...
1) Cry wolf, by claiming that Global Warming will undoubtedly result in the end of Civilization as we know it, by exagerrating scientifc facts, or simply outright lying about the subject, would have you believe in the name of a liberal Democratic agenda,
Or
2) Simply reject or ignore anything and everything that has anything to do with climate change that doesn't agree with a conservative Republican political line,
....Would have you believe.
The truth is far, far more complicated than either political stance. The more you and I investigate, the more we learn that fact to be true.
Years ago, when I first started commenting on this on the old History Channel Message Board, all I said was that the subject demands additional research. Again, it's been years, now, and agencies around the world concur on a lot of subject regarding climate change, and governments around the world have spent billions acting on the conclusions of those agencies.
But even with that, more research is necessary, and more knowledge is needed.
It takes years for something of this magnitude to produce results, positive or negative. It will also take years to act upon those results.
It's our planet, man, and there is NOT a replacement available. Let's do the best we can with this one.
Just a thought.
