"International Rivers Network executive director Patrick McCully today told Brisbane's Riversymposium rotting vegetation and fish found in dams produced surprising amounts of methane - 25 times stronger than carbon dioxide."
"Often it's accepted that hydropower is a climate friendly technology but in fact probably all reservoirs around the world emit greenhouse gases and some of them, especially some of the ones in the tropics, emit very high quantities of greenhouse gases even comparable to, in some cases even much worse than, fossil fuels like coal and gas," Mr McCully said.

What do you think?

I personally don't believe in man-made global warming so you shouldn't presume so; I just saw the page and wanted to share it. Now fateridder I agree with

I believe Global Warming is a lie , designed to control you and steal your hard earned cash .

I think they probably do because they interfere with natural drainage patterns and the evaporation cycle's cloud geography. So do massive parking lots, if you concur with my theory; where there used to be indigenous (esp. plant) life, now there are huge tracts of black superheated surface that becomes a drainage management nightmare in areas with rain and/or snow. Of course immense numbers of self-absorbed, passive-aggressively hostile genetic abominations and deviants (particularly fact and science hating amerikans) will cause some sort of cataclysm on their planet, whether it be slow death by global warming and adapting to breathe carbon-dioxide and methane, or nuclear drama. It's attention for the noisy hordes who rightfully should have been abortions, so they intend to bring the greedy and the conscientious to their blaze-of-glory armageddon party. The cost???--- idk, wait 'till it's over and the cleaning bill comes...

NO DEBATE, let’s get technical and factual:
-dams are produced with concrete. The production of concrete releases 80 to 200 Kg Co2 /ton. This increases with reinforcement bars (steel) needed for the structure. The fact is, a lot of concrete + transportation are needed to build a dam.
-too often, methane is release since the reservoir is filled without having cleared or burned the vegetation in it. As a result, the decay of vegetation in water in large amounts releases methane which has a greenhouse potential 23x higher than CO2
The same problem exists with nuclear power for which uranium is mined and refined using fossil fuels...

Yes, anything and everything can be blamed on global warming. It's a politicians dream because no matter what, the solution is always higher taxes and more control over the individual.

Dams? No, I don't think they do, I think life changes the chemistry of a planets atmosphere. Termites generate far more methane than Dams, and they have been doing it for millions of years.

So all production of power and use of the resources of this planet produce gases and contribute to global warming. Thus we should all turn off our computers or admit we are evil.

I believe over a period of time, past our time there may be a problem, but I see the Earth cycling itself. The methane gas should be taken care of. If they could capture it someway, that would be great.

Global warming-the ultimate tax and control scam.
We are all going to die unless you pay your green taxes.
According to the meteorological globophobes, everything bad is caused by man made global warming.

no the dams are constantly cleaned and maintained
why even worry about iam worried about
nuclear power plants
