Damage Report: LA Methane Leak Is One of the Worst Disasters In US History (inhabitat.com)
MikeChino writes: A week after the ruptured natural gas well in Aliso Canyon was finally declared sealed, we have a full account of the damage — and it doesn't look good. In total, 97,100 metric tons of methane were released into the atmosphere over the course of 112 days — the equivalent greenhouse gas emissions of over half a million cars.
I'd suspect there is more methane released by the cattle on the ranches of the US West in a month than was released by this background noise blip of a "disaster".
We won't know for a while. We'll have to wait for the final death count that can be attributed to climate change and then do some regression analysis. That's assuming of course that humanity survives.
