Methane beginning to melt

This article describes the true problem with our future. Perhaps I'll die of old age before the bad stuff happens, but I have a grandchild who may have to live through the worst of times.

There is no human way to reverse the methane hothouse feedback loop once it is tripped. It doesn't matter whether it is man-made or not, it will be devastating to all higher level life forms. The biochemistry involved will suit only the hardiest of microbes such as those found near geysers and deep sea superheated vents. They will eventually eat all the methane and carbon byproducts after numerous volcanic eruptions have occurred over millions of years.

Of course, almost nothing we do now will make any difference. Maybe some theories about injecting sulfur into the upper stratosphere to increase the planet's albedo have merit, but I think such extreme measures would cause other slightly less horrible conditions for life, such as acid rain lasting for centuries. Actually, since it is an experiment that cannot be performed in advance, nobody really knows what would happen.

All in all, though, whatever marks humans leave on this planet, they will be erased eventually. There will only be shadows of our bones etched into the rocks but no sentient beings to wonder whence they came.
