Things will get dramatically worse much sooner than most believe, we're coming very close to tipping points and feedback loops in the climate. Just read a article on ocean acidification, they are already seeing die offs of mollusk larvae in parts of the world, they cannot grow shells, some oyster farms have already had to relocate. A large percentage of the world population rely on the oceans for food, that is soon going away.
you don't know how right you are; the last 4-5 years in South Florida were on fire..there is hardly a winter anymore.
