Global carbon dioxide and methane levels increased significantly in 2007 |
 24th April 2008, The West Australian
The US National Oceanic and Atmospheric Administration (NOAA) found that in 2007 the level of carbon dioxide, which is the primary gas attributed to global warming, increased by 0.6%, or 19 billion tons. Scientists at the Earth System Research Laboratory also showed that the amount of methane, an even more potent greenhouse gas than carbon dioxide, increased by 0.5% last year, or 27 million tons.

We only have five or 10 years now in which to actually stop the rise in global emissions |
Dr. Bill Hare - a physicist and environmental scientist attached to the Potsdam Institute for Climate Impact Research in Germany since 2002. A lead author of the IPCC's working group on mitigation of climate change.
March 13, 2008 Interview with Kerry O’Brien, 7:30 Report
"Well, there's been quite a few changes observed (since the latest IPCC report) such as the accelerating loss of Arctic sea ice. Some are even saying that we could lose the arctic sea ice within a few years in the summer, something which we projected would happen in 60 or 70 years in the IPCC report. We're also seeing evidence of crop production being adversely affected around the world in the last years to the extent that perhaps the IPCC forecasts of crop losses occurring after two degrees warming are a bit optimistic. On the emissions front, we're also seeing emissions growing much faster than we thought possible in the IPCC report, principally due to growth in China and other developing countries. So, overall, the risk assessment is definitely larger".
"I would say that we only have five or 10 years now in which to actually stop the rise in global emissions before we run out of the chance of limiting warming to two degrees or below. We're simply out of time".

Thermokarst Lakes, a major source of prehistoric methane - And global warming |
25 October 2007, Earth Science
A team of scientists led by a researcher at the University of Alaska Fairbanks has identified a new likely source of a spike in atmospheric methane coming out of the North during the end of the last ice age.
Methane bubbling from arctic lakes could have been responsible for up to 87 percent of that methane spike, said UAF researcher Katey Walter, lead author of a report printed in the Oct. 26 issue of Science magazine. The findings could help scientists understand how current warming might affect atmospheric levels of methane, a gas that is thought to contribute to climate change.

Scientist's climate research in remote Siberia is heating up discussions in the West |
Alex Rodriguez, May 5, 2008, Chicago Tribune
Few places in the world can provide stark evidence of global warming like the peat bogs, lakes and woodlands that stretch eight time zones along Russia's north Siberian coastline.
Melting permafrost awakens dormant microbes that devour thousands of tons of organic carbon, creating methane as a byproduct if no oxygen is present. Subsoil layers of ice also are melting, leaving dips and domes across the landscape and turning roads into mogul runs.

Climate change to take just years |
Marian Wilkinson, Environment Editor, November 15, 2007, The Sydney Morning Herald
AUSTRALIANS will begin to see the stark effects of climate change within the next few years, not the next decades, a leading Australian scientist has warned.
