Rutgers Study in Science... Its the oceans. http://wattsupwiththat.com/2014/10/...-just-the-atmosphere-new-rutgers-study-finds/ Most of the concerns about climate change have focused on the amount of greenhouse gases that have been released into the atmosphere.But in a new study published inScience, a group of Rutgers researchers have found that circulation of the ocean plays an equally important role in regulating the earth’s climate. The study published in Science provides a deeper understanding of the mechanisms of climate change today Thursday, October 23, 2014 In their study, the researchers say the major cooling of Earth and continental ice build-up in the Northern Hemisphere 2.7 million years ago coincided with a shift in the circulation of the ocean – which pulls in heat and carbon dioxide in the Atlantic and moves them through the deep ocean from north to south until it’s released in the Pacific. The ocean conveyor system, Rutgers scientists believe, changed at the same time as a major expansion in the volume of the glaciers in the northern hemisphere as well as a substantial fall in sea levels. It was the Antarctic ice, they argue, that cut off heat exchange at the ocean’s surface and forced it into deep water. They believe this caused global climate change at that time, not carbon dioxide in the atmosphere. “We argue that it was the establishment of the modern deep ocean circulation – the ocean conveyor – about 2.7 million years ago, and not a major change in carbon dioxide concentration in the atmosphere that triggered an expansion of the ice sheets in the northern hemisphere,” says Stella Woodard, lead author and a post-doctoral researcher in the Department of Marine and Coastal Sciences. Their findings, based on ocean sediment core samples between 2.5 million to 3.3 million years old, provide scientists with a deeper understanding of the mechanisms of climate change today. The study shows that changes in heat distribution between the ocean basins is important for understanding future climate change. However, scientists can’t predict precisely what effect the carbon dioxide currently being pulled into the ocean from the atmosphere will have on climate. Still, they argue that since more carbon dioxide has been released in the past 200 years than any recent period in geological history, interactions between carbon dioxide, temperature changes and precipitation, and ocean circulation will result in profound changes. Scientists believe that the different pattern of deep ocean circulation was responsible for the elevated temperatures 3 million years ago when the carbon dioxide level in the atmosphere was arguably what it is now and the temperature was 4 degree Fahrenheit higher. They say the formation of the ocean conveyor cooled the earth and created the climate we live in now. “Our study suggests that changes in the storage of heat in the deep ocean could be as important to climate change as other hypotheses – tectonic activity or a drop in the carbon dioxide level – and likely led to one of the major climate transitions of the past 30 million years,” says Yair Rosenthal, co-author and professor of marine and coastal sciences at Rutgers The paper’s co-authors are Woodard, Rosenthal, Kenneth Miller and James Wright, both professors of earth and planetary sciences at Rutgers; Beverly Chiu, a Rutgers undergraduate majoring in earth and planetary sciences; and Kira Lawrence, associate professor of geology at Lafayette College in Easton, Pennsylvania.
World food production at record levels... (this is for the leftist trolls her like db who don't understand that increasing co2 is apparently very good for food production.)
ACCORDING TO NOAA: NO SIGNIFICANT WARMING IN THE PAST DECADE THERE HAS BEEN A PAUSE IN GLOBAL WARMING SINCE 2000 ACCORDING TO NASA: GLOBAL WARMING HAS SLOWED IT IS A MYSTERY TO NASA WITH RESPECT TO WHY IT HAS SLOWED TEMP IN TOP HALF OF WORLD'S OCEANS ARE NOT CLIMBING FAST ENOUGH TO ACCOUNT FOR STALLED AIR TEMPS WARMING IN DEEP OCEAN IS NOT CAUSING SEA LEVEL RISE WATER TEMP IN DEEP OCEAN HASN'T RISEN SINCE 2005 AIR TEMPERATURES HAVE STALLED
I wrote it a long time ago, and idiots thoughts that it did not make sense. I would have liked it if global warming were a possibility. A lot of great things could be made from global warming, but it won't happen unfortunately. Global cooling on the other hand is a real serious possibility.
I agree that the threat of cooling is far more serious than warming, especially on a planet with a booming population.
This professor deserves are raise... Climate change is happening – but not because of human activity, Daniel Botkin, professor Emeritus in the Department of Ecology, Evolution, and Marine Biology at University of California Santa Barbara has said. Moreover, the focus on man-made global warming is detracting attention from real environmental disasters to nature’s detriment, he has argued. Writing on the National Parks Traveler, a website dedicated to America’s national parks, Botkin challenges the conclusions reached by the Union of Concerned Scientists in their paper National Landmarks at Risk, How Rising Seas, Floods, and Wildfires Are Threatening the United States’ Most Cherished Historic Sites, not least because they’ve taken the standard reports from the IPCC and others, “treating them as accurate and true,” and then used those results to look at the possible outcome for various national parks. “The point of the report, its opening theme and its major conclusion, is that these historic places are in trouble and it’s our fault, we have been the bad guys interfering with nature and therefore damaging places we value,” Botkin says, before methodically knocking down each assertion as demonstrably false. Climate models linking human CO2 output to rising temperatures are unreliable, he writes. “Conclusion: our addition of carbon dioxide to the atmosphere does not appear to be increasing Earth’s temperature. Whatever is happening to Earth’s climate does not seem to be our fault.” However, he does acknowledge that climate change is happening. Taking sea level as an example, he says: “the sea level has been rising since the end of the last Ice Age, starting about 14,000 years ago as the continental and mountain glaciers have melted and sea water has expanded with the overall warming. The average rate has been about a foot or two a century”. The question he poses is: what to do about it? Rather than spending time arguing over the causes of climate change, Botkin advocates simply rolling up our sleeves and dealing with the outcome, harking back to Frederick Law Olmstead, who in the mid 1800s, created the Back Bay Fens on Boston’s shoreline as a way to manage both ocean floods, deal with waste water for the city, and create a recreational area for city dwellers. “Confronted with the combined problems of ocean surges and flooding from river runoff inland, Olmsted did not waste his time complaining about whether or not people have caused the problem. He just set out and solved it.” However, he saves his most damning criticism for the UCS’s treatment of wildfire frequency. The report claims two national park sites are at particular risk of damage from increasingly frequent wildfires, despite the fact that the evidence shows no increase. “Furthermore”, he writes, “it is well-established that most major wildfires that occur these days are from the failure to allow much more frequent, and therefore light fires, to burn. The 20th century policy dominated by Smokey Bear — “only you can prevent forest fires” — and the belief, ill-founded, that all forest and grassland fires are bad and must be prevented — have had a damaging effect.” ‘Damaging’ is an understatement – in fact, the policy caused the extinction of Kirtland’s warbler, a bird which nests in young jack pines, which only regenerate after a fire. The conclusion that Botkin reaches is that, ultimately, “global warming has become the sole focus of so much environmental discussion that it risks eclipsing much more pressing and demonstrable environmental problems. The major damage that we as a species are doing here and now to the environment is not getting the attention it deserves.” http://www.breitbart.com/Breitbart-...th-It-says-University-of-California-Professor
