Study: The Gulf Stream system may already be weakening. That's not good. In the 2004 disaster film The Day After Tomorrow, climate change causes a major disruption of ocean currents in the Atlantic Ocean, which in turn brings about a sudden ice age in New York City.
That scenario was ridiculous and overwrought. Still, the underlying idea that global warming could mess with some important ocean circulation systems actually isn't that far-fetched. Such an event wouldn't blanket Manhattan in ice, but it could wreak havoc on fisheries or speed up sea-level rise in cities like Boston and New York.

(NASA handout via Reuters) A hundred years from now, humans may remember 2014 as the year that we first learned that we may have irreversibly destabilized the great ice sheet of West Antarctica, and thus set in motion more than 10 feet of sea level rise. Meanwhile, 2015 could be the year of the double whammy — when we learned the same about one gigantic glacier of East Antarctica, which could set in motion roughly the same amount all over again.

Bad news: Brazil is losing huge chunks of Amazon rainforest again. Brazil's battle against deforestation was one of the biggest environmental success stories of the last decade.
Between 2005 and 2012, the amount of Amazon rainforest cut down each year fell by 70 percent: (Nepstad et al, 2014) Interaction of ocean oscillations caused 'false pause' in global warming. UNIVERSITY PARK, Pa.-- The recent slowdown in climate warming is due, at least in part, to natural oscillations in the climate, according to a team of climate scientists, who add that these oscillations represent variability internal to the climate system.
They do not signal any slowdown in human-caused global warming. "We know that it is important to distinguish between human-caused and natural climate variability so we can assess the impact of human-caused climate change on a variety of phenomena including drought and weather extremes," said Michael Mann, Distinguished Professor of Meteorology, Penn State. "The North Atlantic and North Pacific oceans appear to be drivers of substantial natural, internal climate variability on timescales of decades. " Mann, Byron A. This is the dumbest thing that happened on the Senate floor today. Leading Climate Denier and Harvard Scientist Took $1.2 Million Bribe From Oil Companies. Wei-Hock Soon, an aerospace engineer and a part-time employee at the Harvard-Smithsonian Center for Astrophysics is one of the few respected scientists who spoke against the general consensus that human activity is a significant contributor to climate change.
He has published 11 papers on climate change since 2008. However, it was recently shown that he received $1.2 million from oil companies in exchange for his “science”. According to leaked documents, the papers were simply “deliverables” that he completed in exchange for their money. He used the same term to describe a testimony he prepared for Congress. Science against money. Sundarbans islands disappear into sea, India, Bangladesh unprepared for 13 million-person exodus.
Last Updated Feb 19, 2015 1:24 PM EST BALI ISLAND, India -- The tiny hut sculpted out of mud at the edge of the sea is barely large enough for Bokul Mondol and his family to lie down.
The water has taken everything else from them, and one day it almost certainly will take this, too. Saltwater long ago engulfed the 5 acres where Mondol once grew rice and tended fish ponds, as his ancestors had on Bali Island for some 200 years. His thatch-covered hut, built on public land, is the fifth he has had to build in the last five years as the sea creeps in. "Every year we have to move a little further inland," he said.

A Brief History of Ice Ages and Warming Causes of Global Climate Change Playing with Numbers A Matter of Opinion Unraveling the Earth's Temperature Record Stopping Climate Change A Brief History of Ice Ages and Warming Global warming started long before the "Industrial Revolution" and the invention of the internal combustion engine.
Global warming began 18,000 years ago as the earth started warming its way out of the Pleistocene Ice Age-- a time when much of North America, Europe, and Asia lay buried beneath great sheets of glacial ice. Earth's climate and the biosphere have been in constant flux, dominated by ice ages and glaciers for the past several million years. UN says CO2 pollution levels at annual record high - Science. GENEVA — Carbon dioxide levels in the atmosphere reached a record high in 2013 as increasing levels of man-made pollution transform the planet, the UN weather agency said Tuesday.
The heat-trapping gas blamed for the largest share of global warming rose to worldwide concentrations of 396 parts per million last year, the biggest year-to-year change in three decades, the World Meteorological Organization said in an annual report. Continue reading below That’s an increase of 2.9 parts per million from the previous year and is 42 percent higher than before the Industrial Age, when levels were about 280 parts per million. Based on the current rate, the world’s carbon dioxide pollution level is expected to cross the 400 parts per million threshold by 2016, said organization Secretary General Michel Jarraud. That is way beyond the 350 amount that some scientists and environmental groups promote as a safe level and that was last seen in 1987.

Researchers show Earth's magnetic reversal occurs faster than previously thought. A study by researchers from UC Berkeley, Columbia University, Italy and France shows that the most recent reversal of Earth’s magnetic field occurred in fewer than 100 years, which is much more rapidly than previously believed. Courtney Sprain, campus graduate student, and Paul Renne, director of the Berkeley Geochronology Center and a campus earth and planetary sciences professor, worked with overseas researchers to study the magnetic properties of sediments in Italy. When They Brought These Wolves Into The Park, They Had No Idea This Would Happen.
Louisiana Loses Its Boot — Matter. Early this year, I drove from Arnaudville, Louisiana, to Morgan City, hoping to walk where I’d heard there was land. Arnaudville is in Cajun country, in the southern part of the state. Morgan City is roughly halfway between Lafayette and New Orleans, if you take the Highway 90 route. Directionally speaking, that’s all I knew. I was aware Arnaudville is just outside Lafayette, but I couldn’t have told you in what direction, even though I’d been there several times before. An Open Source Plastic-Recycling Machine, From the Inventor of Phonebloks. Last fall, Dutch designer Dave Hakkens released Plonebloks, a concept for a modular phone that set the internet on fire.
Dave Hakkens Hakkens, a recent graduate of The Design Academy in Eindhoven, actually had another thesis project that year: Precious Plastics. The series of magpie-like machines turn discarded plastic bottles and trash into new housewares. Precious Plastic consists of a shredder, plus three different kinds of small-scale manufacturing machines: a rotational molding device, an extrusion machine, and an injection molding machine. Hakkens built them all from sheet metal and scrap parts. Big Freeze Triggered by Flood Path Reckon Climate Scientists : environment : NatureWorldNews. Nov 13, 2012 12:56 AM EST Scientists have come up with an explanation for the 1200-year-long ice up also called the big freeze, the last major cold age on Earth.
Geo scientist Alan Condron of the University of Massachusetts Amherst, along with Peter Winsor at the University of Alaska, have concluded that a climate-cooling period known technically as 'Younger Dryas' or just 'Big Freeze', occurred after glacial Lake Arassiz, at the southern edge of the Laurentide ice sheet covering Hudson Bay and much of the Canadian Arctic broke through an ice dam and pumped in thousands of cubic miles of fresh water into the ocean.
"This episode was the last time the Earth underwent a major cooling, so understanding exactly what caused it is very important for understanding how our modern-day climate might change in the future," says Condron. The flood flowed north into the Arctic down the Mackenzie River valley first. . © 2014 NatureWorldNews.com All rights reserved. US Solar. Carbon emissions 'will defer Ice Age' 9 January 2012Last updated at 06:20 By Richard Black Environment correspondent, BBC News The climate, if not species, of an Ice Age "ought" to return within 1,500 years Human emissions of carbon dioxide will defer the next Ice Age, say scientists. Climate Change: Study Says Dire Warnings Fuel Skepticism. Report: 97 percent of scientists say man-made climate change is real - Science Fair: Science and Space News. Updated 2010-06-22 5:43 PM Forget the four out of five dentists who recommend Trident….
Try the 97 out of 100 scientists that believe in man-made climate change. This data comes from a new survey out this week in the Proceedings of the National Academy of Sciences. The study found that 97 percent of scientific experts agree that climate change is "very likely" caused mainly by human activity. The report is based on questions posed to 1,372 scientists.
