Strange, real strange. Amazing photos of bizarre subject. Those events that destroy earth's crust are attention getters.

there is a lot of methane in the Siberian permafrost. as it releases the greenhouse effect will accelerate. this is not good.

I would imagine there's enough methane stored there that one good release would dwarf all the CO2 ever released by humankind in their entire existence on the planet. Go figure...

We have some sinkholes in Canada's north. "Karst is a term for a feature that forms on the landscape when water dissolves soluble bedrock such as limestone, marble, or dolomite. The resulting topography can include caves, sinkholes, springs, and disappearing streams, sometimes forming complex underground drainage systems. Karst areas in the NWT are important for several reasons. The substrate and chemical composition of karst landscapes creates unique habitats for aquatic and terrestrial species. Some species have adapted specifically to the karst environment and cannot survive anywhere else. Other species thrive there because of the relatively rich nutrient load in some karst soils. Physical characteristics of karst features provide important habitat for species such as bats, Dall's sheep and other vertebrates and invertebrates that rely on caves for at least part of their lifecycle. The constant climatic conditions in subterranean karst provide an ideal environment for the preservation of fossils. Most of the karst systems in the NWT are remote and some are poorly studied. The most well-known karst systems are within the newly expanded Nahanni National Park Reserve."

bcrockhound, we have a lot of them around here, too. We have lots of pristine wetlands, an underground river that empties into Huron, karst, some beautiful, beautiful bogs. This world is full of wonderful things.

Winter Haven Florida, land of round lakes. Sink hole city. but not like those deep pits bc has.

that must be one of the places you see pictures of where there is a car in the middle of a sinkhole right in the middle of the street, or maybe a house with a new sinkhole for a basement. I think I'd be a mite uneasy to settle there.

any sinkhole that swallows you house sucks. Fortunately there are not too many houses in Siberia. The Florida sinkholes are from limestone erosion. The Siberian ones seemed to be rapid methane ice melting and explosive expansion. Lee is correct about the potential for Siberian methane release to dwarf (or at least comparable) to total man-made greenhouse gas. But the two are related. In the regular heating and cooling cycles of the globe, this cycle has continued to warm instead of already starting to cool. Consensus is that man-made activity has nudged the regular cycle. While very difficult (practical and political) to change man-made contributions, if all the methane in the Siberian permafrost releases, we don't have a chance of controlling that. This is why I support a cap on carbon. citizensclimatelobby.org/climate-change-solutions-speak-up-for-climate/

AlGores "green" initiatives serve no purpose but to put folding green into his and his cronies pockets. It's all about the benjamins.

Sorry you feel that way Daniel. I didn't know there was such a thing as a "normal" rockhound. How is it unreasonable to question a science that appears to mainly fill the pockets of the true believers. The predictions of the models generated years back in no way even slightly resemble what has occurred, climate wise. Data has repeatedly been cherry picked or rejected when it didn't support the theory. Global warming scientists refuse to enter into meaningful debate, choosing instead to level personal attacks at the "deniers". I have no problem with the idea of finding better ways to produce energy, viable alternatives to burning things are definitely a good thing. So far most of our supposedly green technology has more of a negative impact on our planet than what it is supposed to replace. It sure does make the rich guys a lot richer though. Ethical scientists nowadays must really be able to understand how Galileo felt.

I don't know about you, we have just had the coldest February on record. I wonder how that happened. Hmmm, cold air coming out of the Arctic? Seems plausible. Why or how is cold air flowing south? Now lets figure this out. Last I knew, cold are is more dense than warm air...the cold air would sink in the atmosphere. Likewise warm air is less dense so it would rise above the colder air. If the warm air rises, something has to replace it. What you might ask? Cooler air is the answer. From where does the cooler air originate? The Arctic and Antarctic regions is the answer. I'm talking global scale not hill and valley local stuff.
Following this line of reasoning out would lead an intelligent person to come to the conclusion that a hell of a lot of warm air has to go to the polar regions to make a hell of a lot of cold air. If we are having colder winters, the oceans have to be warmer than what we consider normal. Oceans cover more of the earth's surface than land and will hold more solar energy - heat, which heats the air, which goes to the poles, cools, and freezes our asses.
Regardless of what you think, we do have an effect on the global temperature cycles, because we do cause the release of greenhouse gases over and above what nature releases. Anything added to the total, well, increases the total amount. I do not believe we are a major factor, but we are a factor.
