Ask yourself though, even if all this climate change and global warming is FUD, what happens if we respond to it like it is real? Result: we have a cleaner planet (cleaner air, cleaner water, oceans that still support life) and we have a sustainable path when fossil fuels do eventually run out.
What happens if we ignore it? Result: the potential demise of the world as we know it...
Think about it from a risk vs reward perspective. It's clearly much riskier to ignore than it would be to take a hit on our economic growth and pivot hard to 100% renewable energy.
