Mammoths to save the world?

Apparently grass is better at insulating the ground and keeping it frozen during the summer months than trees. This guy has confirmed this through observations of ground temperatures. The elephants help turn forests into grasslands.

Global warming is the reason the permafrost is melting. Having it warm enough to use elephants to stave off forest succession appears a bit late to me.

I think the idea is to mitigate the feedback by slowing the release of additional methane. I think they also mentioned that the grass in lighter colored than the trees so it reflects more heat back into space as well as insulating the ground. It isn't supposed to be a cure for global warming. Just something to help slow it down. I don't know if it will work, but it doesn't sound like it would hurt either...
