Eric Risberg/AP Scientists blame higher levels of carbon dioxide in Pacific Ocean waters caused by global warming for the failure of oyster seeds to thrive in hatcheries. Austin Docter has worked at a shellfish plant in Shelton, Wash., for 18 years and has a lot of words to describe what he calls the flavor profiles of oysters: Minerally. Metallic-y. Sweet. Greenland Ice Melt, Measured By NASA Satellites, Reaches Unprecedented Level. Unprecedented melting of Greenland's ice sheet this month has stunned NASA scientists and has highlighted broader concerns that the region is losing a remarkable amount of ice overall.
According to a NASA press release, about half of Greenland's surface ice sheet naturally melts during an average summer. But the data from three independent satellites this July, analyzed by NASA and university scientists, showed that in less than a week, the amount of thawed ice sheet surface skyrocketed from 40 percent to 97 percent. Global Warming's Terrifying New Math. Study casts doubt on popular mass extinction theory. Mussels and other species of sea animals died in large numbers at the end of the Triassic geological period. Scientists are trying to understand why. (Photo: Colourbox) About the time, 201 million years ago, that the super-continent Pangaea – the single land mass made up of all the present continents – started to break up, life on Earth was hit by a severe crisis that killed off numerous animal species. On land, the devastation was not so bad, although many plants did wither and die.
Rise in sea level can't be stopped: scientists. By Nina Chestney LONDON Sun Jul 1, 2012 10:32pm IST LONDON (Reuters) - Rising sea levels cannot be stopped over the next several hundred years, even if deep emissions cuts lower global average temperatures, but they can be slowed down, climate scientists said in a study on Sunday.
A lot of climate research shows that rising greenhouse gas emissions are responsible for increasing global average surface temperatures by about 0.17 degrees Celsius a decade from 1980-2010 and for a sea level rise of about 2.3mm a year from 2005-2010 as ice caps and glaciers melt. 'Hot Spring': Record Temps Herald Era of Warmer World. With the warmest March, third warmest April and second warmest May, the National Oceanic and Atmospheric Administration confirmed on Thursday that the 2012 Spring in the contiguous United States since has been the hottest ever on record.
(Source: NOAA) The spring season's (March-May) nationally-averaged temperature was 57.1°F, 5.2°F above the 1901-2000 long-term average, surpassing the previous warmest spring (1910) by 2.0°F. The nation has experienced since recordkeeping began in 1895, NOAA reported. Search Results. Journal home : Nature Climate Change. Climate change makes cod grow. Global warming doesn’t only have negative effects.
Clouds’ Effect on Climate Change Is Last Bastion for Dissenters. Over time, nearly every one of their arguments has been knocked down by accumulating evidence, and polls say 97 percent of working climate scientists now see global warming as a serious risk.
Yet in recent years, the climate change skeptics have seized on one last argument that cannot be so readily dismissed. Their theory is that clouds will save us. They acknowledge that the human release of greenhouse gases will cause the planet to warm. Arctic Sea Emits Methane. Atmospheric scientist Eric Kort was flying over the Arctic Ocean three years ago, monitoring readouts as onboard sensors sniffed the air.
Suddenly, as the plane dipped low over some breaks in the sea’s ice cover, those instruments detected the unmistakable whiff of methane, the second most important climate-warming gas associated with human activities. “This was unexpected,” says Kort, of NASA’s Jet Propulsion Laboratory in Pasadena, Calif. Computer model predicts tomorrow’s nature. Computers’ powers of calculation have developed considerably in recent years – a situation that researchers have used to create complex simulation models of nature.
The new Danish model is a sort of virtual experiment that is based on reality. Therefore the models offer new possibilities of understanding and predicting changes in the future. (Photo: Colourbox) How will nature be affected if we change agricultural subsidies, use other pesticides or build a motorway? So far, researchers have not had usable tools or information for answering such questions without time-consuming and expensive fieldwork. But this will be easier in the future after researchers at Aarhus University have developed an advanced computer model that makes it possible to simulate various future scenarios in nature, based on the real world. It's Getting Hot in Here: Understanding the Impact of the "Meteorological March Madness"
It's going to take some time for science to catch up with what happened this past winter. For instance, a lot has been made of the "Meteorological March Madness" we just experienced, in which over 15,000 local, all-time warm-weather temperature records were broken across the U.S. NOAA: More Than 15,000 Temperature Records Broken In March.

On the Brink: Planet Near Irreversible Point of Global Warming. We may have already passed the tipping points on global warming, say scientists at the Planet Under Pressure conference.
At the London conference, scientists are giving a bleak view of the future of the planet due to catastrophic damage and growth by humans, saying we are close to the irreversible point of global warming. Will Steffen, executive director of the Australian National University's climate change institute, gave an urgent warning that humanity needs to act radically on climate change. Gulf Oil Spill: Coral Death 'Definitively' Linked To BP Spill. San Francisco Fights Erosion as Coastal Cities Watch Closely. Unprecedented, "Eye-Popping" Temperatures Soar, Highs Continue. People from the Midwest and Northeast have been stepping out to record-setting temperatures this month.
Meteorologists are calling the temperatures unprecedented. Deke Arndt, who leads the climate monitoring branch of the National Climatic Data Center in Asheville, N.C., said, “This will be a March event that we’ll look back on as one of the big March events of modern history.” And Jonathan Martin, chairman of atmospheric and oceanic sciences at UW-Madison, adds, "This is to me the most unusual weather event I've witnessed in my lifetime. " Weather maps show many areas with temperatures at 30 degrees above normal days in a row. CO2 is confusing fish.
A team of researchers has discovered how fish respond to increased levels of CO2 in sea waters. Climate towers in the Faroes? CO2 map provides quality control for climate research.
