    There were huge numbers of beaver in North America before they were heavily trapped. And the CO2 in the atmosphere was stable at 280 ppm. Notice that the article stated that the dams produced both sinks and sources of carbon. Could potentially release about 820,000 tons of carbon annually? We humans put over 40 billion tons of carbon into the atmosphere annually. That is 820,000 tons versus 40,000,000,000 tons. Anything else, dumbass deniers?

    How many tons did the dinosaurs put out, because they froze to death.

    Why are you so anti science? Took over 10,000 years for the extinction, and not all of them died.

    Weatherman always finds the strangest things to worry about. He's not happy unless he's melting down. This time, he's freaking over beavers.

    As is always the case, when we go to the original source, we find out it doesn't say what deniers claim. Instead, it says that beaver habitat is both a source and sink, and that more study is needed. However, common sense would indicate that long term, it all evens out.

    Both C sequestration and CO2 and CH4 emissions in ponds of various ages should be taken into account when considering the net effect of beavers on the C dynamics. With present estimates, beaver ponds globally range from a sink (−0.47 Tg year−1) to a source (0.82 Tg year−1) of C. More research is needed with continuous flux measurements and from ponds of different ages. Likewise, there is a need for more studies in Eurasia to understand the effect of beaver on C biogeochemistry.

    Don't blame Weatherman too much here. That Engineering Times article he linked to was wildly slanted, mentioning only sources and neglecting sinks. He just copied it, and it's not like he's capable of fact checking. If he could fact-check, he wouldn't be a denier.
