A new report from the National Aeronautics and Space Administration (NASA) finds that the Antarctic ice cap has exceeded 20 million square kilometers, a freeze that hasn't been seen since 1979 when the agency began to compile records.
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.

Scientists believe they have discovered a near-unprecedented phenomenon - rarer, more elusive and mysterious than even the God Particle: an article in The Huffington Post on the subject of the environment and climate change which doesn't once mention 'man-made global warming."
1. It's a terrible accident. "Huff Po has a very strict rule which states that all environmental problems are the fault of mankind, that the planet is warming catastrophically and that only by funneling more money into the pockets of Al Gore and anyone, like those nice people at Solyndra, who donated to the Obama re-election campaign can it be preserved for future generations. Perhaps the author of the piece simply forgot this rule. The penalty will be severe: exile to one of HuffPo's Siberian yoghurt-weaving collectives, at least, if not actual death."
2. There has been an incredible, tectonic shift in HuffPo's understanding of the world. It is now swinging round to the more scientifically plausible viewpoint that climate is driven by solar activity and that this late season freeze on the Great Lakes is yet another sign that we may be entering a prolonged period of global cooling.

An Italian adventurer will be packing his bags and moving to an iceberg in Greenland so he can reverse global warming. He plans on living there for eight to twelve months, which is the length of time he expects that his new home will exist before it melts into water.

Twenty million years ago the Indian and Asian continental plates clashed and pushed up the massive Tibetan plateau. In summer this plateau acts as a huge heat engine, absorbing solar energy which it transfers to the atmosphere, causing immense convection currents. With all this hot air rising, air is sucked in from all round, including moist air from the Indian Ocean that produces intense South East Asian monsoons.

The United Nations, ever eager to embrace global warming, has a new climate report to be released that claims scientists are more certain than ever that global warming is real, but now there is hard evidence that global surface temperatures have stabilized over the last 15 years according to the U.K.’s weather-watching Met Office.
Scientists believe causes could include: greater-than-expected quantities of ash from volcanoes, which dims sunlight; a decline in heat from the sun during a current 11-year solar cycle; more heat being absorbed by the deep oceans; or the possibility that the climate may be less sensitive than expected to a build-up of carbon dioxide.
The text is likely to change in response to comments from governments received in recent weeks and will also be considered by governments and scientists at a four-day approval session at the end of September. It is therefore premature and could be misleading to attempt to draw conclusions from it.

“It is unfortunate that on a matter of such importance to all Americans that the administration has chosen to bypass our elected representatives in favor of unilateral actions and go-it-alone tactics,” he said.
Obama’s plans did generally win praise from the environmentalist community.

"EN TIEMPOS DIFÍCILES" - Heberto Padilla
A aquel hombre le pidieron su tiempo
para que lo juntara al tiempo de la Historia.
Le pidieron las manos,
porque para una época difícil
nada hay mejor que un par de buenas manos.
Le pidieron los ojos
que alguna vez tuvieron lágrimas
para que contemplara el lado claro
(especialmente el lado claro de la vida)
porque para el horror basta un ojo de asombro.
Le pidieron sus labios
resecos y cuarteados para afirmar,
para erigir, con cada afirmación, un sueño
le pidieron las piernas
duras y nudosas
(sus viejas piernas andariegas),
porque en tiempos difíciles
¿algo hay mejor que un par de piernas
para la construcción o la trinchera?
Le pidieron el bosque que lo nutrió de niño,
con su árbol obediente.
Le pidieron el pecho, el corazón, los hombros.
que eso era estrictamente necesario.
Le explicaron después
que toda esta donación resultaria inútil.
sin entregar la lengua,
porque en tiempos difíciles
nada es tan útil para atajar el odio o la mentira.
Y finalmente le rogaron
que, por favor, echase a andar,
porque en tiempos difíciles
esta es, sin duda, la prueba decisiva.
