This was a natural eruption of CO2 which was not caused by global warming, but I think it shows that CO2 is much more dangerous then many people realize. We didn't even realize that there was any danger from Lake Nyos until this eruption occurred. Are we reaching the point where we are now starting to truly recognize the danger of CO2 accumulation in the atmosphere? Have we reached a tipping point on climate crisis?
Lake Nyos can serve as an example of both crisis and hope regarding the climate crisis. Today there are pipes going to the bottom of the lake to release CO2 from the lake and help to prevent another incident in the future. This "degassing" is also a potential source of renewable, sustainable energy. (Although not CO2 free, but this is a naturally occurring CO2.)
We can all go see "An Inconvenient Truth" and learn more about global warming and the climate crisis. We can all reduce our global footprint and reduce our use of CO2 producing products. These are all important things to do. But, how are we going to start "degassing" the atmosphere? That is the next step.
