Ocean currents are slowing.  That's fact.  In the past, each time the ocean currents slowed, we entered an Ice Age.  That's fact.  Nothing else really matters, unless we can speed up the ocean currents. The "sky is falling" crowd couldn't prove "Global Warming", so they changed it to "Climate Change", as if that's something that never happens.  Also kept the grant money rolling in if they could write a scary enough grant application to freak out the organizations who hold the purse strings.
