Climate warning as Siberia melts - environment - 11 August 2005 - New Scientist - 0 views

  •  
    Kirpotin describes an "ecological landslide that is probably irreversible and is undoubtedly connected to climatic warming". He says that the entire western Siberian sub-Arctic region has begun to melt, and this "has all happened in the last three or four years".

Too late? Why scientists say we should expect the worst of global warming | Environment... - 0 views

  •  
    Despite the political rhetoric, the scientific warnings, the media headlines and the corporate promises, he would say, carbon emissions were soaring way out of control - far above even the bleak scenarios considered by last year's report from the Intergovernmental Panel on Climate Change (IPCC) and the Stern review. The battle against dangerous climate change had been lost, and the world needed to prepare for things to get very, very bad.

Greenland's ice cap melting faster than expected: experts - 0 views

  •  
    Greenland's ice cap, which covers more than 80 percent of the island, is melting faster than expected because of global warming, a Danish researcher said on Monday.

Earth Overshoot Day Sept 23 2008 - 0 views

  •  
    September 23 this year marks an unfortunate milestone: the day humanity will have used all the resources nature will generate this year, according to Global Footprint Network data. Earth Overshoot Day marks the day when humanity beings living beyond its ecological means. Beyond that day, we move into the ecological equivalent of deficit spending, utilizing resources at a rate faster than what the planet can regenerate in a calendar year.

    Globally, we now now require the equivalent of 1.4 planets to support our lifestyles. But of course, we only have one Earth. The result is that our supply of natural resources -- like trees and fish -- continues to shrink, while our waste, primarily carbon dioxide, accumulates.

Economics of Climate Change - 0 views

  • The draft report of the Garnaut Climate Change Review, a similar study conducted in Australia in 2008 by Ross Garnaut broadly endorsed the approach undertaken by Stern, but concluded, in the light of new information, that Stern had underestimated the severity of the problem and the extent of the cuts in emissions that were required to avoid dangerous climate change.
  • Its main conclusions are that one percent of global gross domestic product (GDP) per annum is required to be invested in order to avoid the worst effects of climate change, and that failure to do so could risk global GDP being up to twenty percent lower than it otherwise might be.

    He states, "our actions over the coming few decades could create risks of major disruption to economic and social activity, later in this century and in the next, on a scale similar to those associated with the great wars and the economic depression of the first half of the 20th century."[3][4] In June 2008 Stern increased the estimate to 2% of GDP to account for faster than expected climate change.[5]

McClatchy Washington Bureau | 09/12/2008 | Study finds recent global warming unpreceden... - 0 views

  •  
    Its conclusion is that temperature increased and decreased a little over the centuries, but the fluctuations were small enough that the line was roughly flat, like the shaft of a horizontal hockey stick. Then, from about 1980 to now, temperature increased sharply, more than any increase before - like the blade of the hockey stick.

    For the past 10 years, climate-change skeptics have been calling the hockey stick bogus. Now the scientists who studied the climate record and produced the original hockey-stick graph have done a new study using more data from more sources - and they got the same pattern.

GeoEye-1...Scheduled for launch Sept. 04, 2008. The World's Most Advanced Earth Imaging... - 0 views

  •  
    GeoEye-1, designed and built by General Dynamics Advanced Information Systems, is the world's highest resolution commercial imaging satellite. Designed to take color images of the Earth from 423 miles (681 kilometers) in space and moving at a speed of about four-and-a-half miles (seven kilometers) per second, the satellite will make 15 earth orbits per day and collect imagery with its ITT-built imaging system that can distinguish objects on the Earth's surface as small as 0.41-meters (16 inches) in size in the panchromatic (black and white) mode. The 4,300-pound satellite will also be able to collect multispectral or color imagery at 1.65-meter ground resolution. While the satellite will be able to collect imagery at 0.41-meters, GeoEye's operating license from NOAA requires re-sampling the imagery to half-meter resolution for all customers not explicitly granted a waiver by the U.S. Government.

    Many extremes and their associated impacts are now changing.
    For example, in recent decades most of North America has been
    experiencing more unusually hot days and nights, fewer unusually cold
    days and nights, and fewer frost days. Heavy downpours have become
    more frequent and intense. Droughts are becoming more severe in some regions, though there are no clear trends for
    North America as a whole. The power and frequency of Atlantic hurricanes have increased substantially in recent decades,
    though North American mainland land-falling hurricanes do not appear to have increased over the past century. Outside
    the tropics, storm tracks are shifting northward and the strongest storms are becoming even stronger.

New Greenland Ice Cracks Worry Scientists - 0 views

  •  
    In northern Greenland, a part of the Arctic that had seemed immune from global warming, new satellite images show a growing giant crack and an 11-square-mile chunk of ice hemorrhaging off a major glacier, scientists said Thursday.

BBC NEWS | Science/Nature | World heading towards cooler 2008 - 0 views

  •  
    Data from the UK Met Office shows that temperatures in the first half of the year have been more than 0.1 Celsius cooler than any year since 2000.

    The principal reason is La Nina, part of the natural cycle that also includes El Nino, which cools the globe.

    Even so, 2008 is set to be about the 10th warmest year since 1850, and Met Office scientists say temperatures will rise again as La Nina conditions ease.

    There's been a lot of pressure lately to open up protected areas for oil drilling. But common sense says drilling is not the answer. Switching is.

    Unlike America, Denmark, which was so badly hammered by the 1973 Arab oil embargo that it banned all Sunday driving for a while, responded to that crisis in such a sustained, focused and systematic way that today it is energy independent.

    It seems the Post Carbon Institute is as excited to push toward meeting Al Gore's challenge as we are. Julian Darley, the Institute's Founder and author of High Noon for Natural Gas: The New Energy Crisis, posted an outline to their web site detailing the ten steps the country would need to take in order to meet the goal of producing 100% of our nation's electricity in 10 years.

Cities to count emissions with Carbon Disclosure Project | Green Tech - CNET News.com - 0 views

  •  
    How can cities reduce the role they may play in global warming? Could fire departments, garbage collection services, residential building codes, and industrial regulations be greener?

    Attempting to help address those questions, 21 U.S. cities, including New York, Las Vegas, and New Orleans will describe their major sources of greenhouse gas emissions to the Carbon Disclosure Project, one of the world's largest repositories linking such data to climate change.

Climate change caused widespread tree death in California mountain range - 0 views

  •  
    This study is the first to show directly the impact of climate change on a mountainous ecosystem by physically studying the location of plants, and it shows what could occur globally if the Earth's temperature continues to rise. The finding also has implications for forest management, as it rules out air pollution and fire suppression as main causes of plant death.
