Britain's genius physicist #StephenHawking closed his eyes to mankind with one prediction. "For humans to survive, I believe we must have the preparations in place within 100 years."

By 2050, more than 1 billion people are expected to be refugees due to fine dust, cold waves and heat waves. Hawking has warned that "#Globalwarming is reaching an irreversible #tipping_point."

No one knows when the tipping point is, but it's still true that you're closer than ever. So, what do we have to do now?
