The researchers have listed and ranked nine ecological systems that they say could be lost this century as a result of global warming. The nine tipping elements and the time it will take them to undergo a major transition are:
* Melting of Arctic sea-ice (about 10 years)
* Decay of the Greenland ice sheet (about 300 years)
* Collapse of the West Antarctic ice sheet (about 300 years)
* Collapse of the Atlantic thermohaline circulation (about 100 years)
* Increase in the El Nino Southern Oscillation (about 100 years)
* Collapse of the Indian summer monsoon (about 1 year)
* Greening of the Sahara/Sahel and disruption of the West African monsoon (about 10 years)

Sep. 9, 2005 Methane Gyrations Last 2,000 Years Show Human Influence On Atmosphere:

Citat: "...
"The results frankly were a shock," said White. "We can see human fingerprints all over atmospheric methane emissions for at least the last 2,000 years. Humans have been an integral part of Earth's carbon cycle for much longer than we thought."
...
Overall methane levels in the atmosphere increased about 2 percent from about 1 A.D. to 1000 and decreased by 2 percent from 1000 to 1700, according to the study. Since the 1700s, the levels have increased by nearly 300 percent, said White.

"There has been a[ ]naïve idea out there that humans were just passive, pastoral passengers on the planet up until just a few hundred years ago," he said. "We have shown that is not the case."

"... Pollen and leaf data support the idea that millions of trees sprang up on abandoned farmland, soaking up carbon dioxide from the atmosphere... increase in cereal pollen from 1200 onwards (reflecting agricultural expansion), followed by a sudden dive around 1347, linked to the agricultural crisis caused by the arrival of the Black Death...

When the team analysed glacial seismic records back to 1993, they found a striking increase in the number of quakes recorded in recent years. All 136 of the best-documented slips were traced to glaciated valleys draining the main Greenland ice sheet. A handful of others occurred in Alaskan glaciers or on Antarctica.
Ekström reports that quakes ranged from six to 15 per year from 1993 to 2002, then jumped to 20 in 2003, 23 in 2004, and 32 in the first 10 months of 2005 - matching an increase in Greenland temperatures.

May 8, 2008 Ponds Found To Take Up Carbon Like World's Oceans
http://www.sciencedaily.com/re....htm
Citat: "... Professor Downing found that constructed ponds and lakes on farmland in the United States bury carbon at a much higher rate than expected; as much as 20-50 times the rate at which trees trap carbon. In addition, ponds were found to take up carbon at a higher rate than larger lakes.
...
"Aquatic ecosystems play a disproportionately large role in the global carbon budget," Downing said.
...
The combined effect is that farm ponds could be burying as much carbon as the world's oceans, each year.
...
It may be that ponds will be the modern equivalent of the swamps that formed coal in the past. But before we all rush into making ponds to trap carbon we need to do some basic research here in the UK

Apr. 23, 2008 Increasing Levels Of Atmospheric Carbon Dioxide Cause A Rise In Ocean Plankton Calcification:

Citat: "...
Previously, the fact that carbon dioxide made the oceans more acidic was thought to be harmful to all organisms that produce calcium carbonate - for example, corals and coccolithophores (a group of calcium carbonate-producing phytoplankton). However, observations in the laboratory and the deep ocean have shown that the calcification of coccolithophores increases significantly with rising carbon dioxide (CO2) levels, produced by human activity.

Nov. 2, 2007 Cirrus Disappearance: Warming Might Thin Heat-trapping Clouds:
http://www.sciencedaily.com/re....htm
Citat: "...
The widely accepted (albeit unproven) theory that manmade global warming will accelerate itself by creating more heat-trapping clouds is challenged this month in new research from The University of Alabama in Huntsville
...
What we found in month-to-month fluctuations of the tropical climate system was a strongly negative feedback. As the tropical atmosphere warms, cirrus clouds decrease
...
"The role of clouds in global warming is widely agreed to be pretty uncertain," Spencer said
...
"Fifteen years ago, when we first started monitoring global temperatures with satellites, we noticed these big temperature fluctuations in the tropics," Spencer said. "What amounts to a decade of global warming routinely occurs in just a few weeks in the tropical atmosphere. Then, as if by flipping a switch, the rapid warming is replaced by strong cooling. It now looks like the change in cirrus cloud coverage is the major reason for this switch from warming to cooling."
...
This unexpected behavior was traced to the decrease in cirrus cloud cover.
...
There are significant gaps in the scientific understanding of precipitation systems and their interactions with the climate, he said. "At least 80 percent of the Earth's natural greenhouse effect is due to water vapor and clouds, and those are largely under the control of precipitation systems
