To sum up that video we need to do a few things to stop climate change. 
 
1.   Get our population down. This means investing in contraception and reducing birth rates. 

2.   Optimize for efficiency. The more efficient we get, the less energy it takes to run our society, the less emissions we produce. However we can't just rely on efficiency alone to solve all our problems.

3.   Use today's technology! We have a lot of the technology to stop Climate Change but we aren't using it nearly enough. There are other things we could be doing too, like leaving nuclear power plants on longer, use funding from fossil fuels to fund renewables or we can price carbon emitting industries harshly to create an incentive to switch to more sustainable options.

4.   We need to innovate! We need to make new and better technologies to tackle climate change.

5.   We need to take action, that can mean a lot of different things like reducing your energy consumption or voting for the Green New Deal.

Whatever it means to you we will talk about what you can do on the page titled What. Solving Climate Change is no one thing. It is going to take an army of little things to stop it. One more light switched off, one more wind turbine, one more activist, one new invention and much much more.
