Global Warming:A Chilling Perspective. 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. We are currently enjoying a temporary reprieve from the deep freeze. 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. They Took A Camera To A Remote Area In Greenland, And What They Recorded Is Simply Terrifying. 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. Published this summer, the research investigated the last magnetic reversal, which happened 786,000 years ago. 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. 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.
The last Ice Age ended about 11,500 years ago, and when the next one should begin has not been entirely clear. Climate Change: Study Says Dire Warnings Fuel Skepticism. While researching a feature for TIME.com recently, I had the chance to sift through TIME's decades of environment coverage.
I came to two conclusions: First, we were writing stories about virtually the same subjects 40 years ago as we do now. (Air pollution, endangered species, the polluted oceans, dwindling natural resources.) Second, our coverage of climate change has been really scary — by which I mean, we've emphasized the catastrophic threats of global warming in dire language. 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. Old Military Planes to Drop 900,000 Tree-Bombs a Day. Image: a C-130 Hercules dropping something other than tree-bombs.
Suggestsoft I've always felt that planting trees was simply too much of a non-violent affair. Digging holes, lowering in saplings, filling them with soil -- yawn. Wik-Bee Leaks: EPA Document Shows It Knowingly Allowed Pesticide That Kills Honey Bees. The world honey bee population has plunged in recent years, worrying beekeepers and farmers who know how critical bee pollination is for many crops. A number of theories have popped up as to why the North American honey bee population has declined--electromagnetic radiation, malnutrition, and climate change have all been pinpointed. Now a leaked EPA document reveals that the agency allowed the widespread use of a bee-toxic pesticide, despite warnings from EPA scientists. The document, which was leaked to a Colorado beekeeper, shows that the EPA has ignored warnings about the use of clothianidin, a pesticide produced by Bayer that mainly is used to pre-treat corn seeds.
Climate Change Debate Unfolded. I intend to come back to this strip and rewrite some of the first half, in order to make the science clearer. I'm sure there will be a few spelling errors and suchlike. Feel free to point them out, but keep in mind that I've been staring at many of these pages for weeks, to the point where even the word 'and' looks funny to me. I shall be adding on references to this strip over the coming few days.
