> The IPCC’s own estimates of the business as usual scenario show modest economic impacts even under a business as usual scenario out to 2100.

This sounds a lot like you are saying "if we continue business as usual, the world won't be destroyed before 2100", which might well mean "but it's completely impossible to escape complete destruction until 2150 then".
