Think global, act local.

In a perfect world global emissions would have peaked already. In a semi-perfect world we will peak on Dec. 31, 2020. The fact is, that's going to be difficult. We know that it's going to get more and more expensive the longer we delay.

You can rear children in an antagonistic environment or in a facilitative one with a good combination of love and discipline. It's about supporting them, and recognizing achievements and contributions, but also saying, "that's fantastic but it's not enough, here's the next thing."

Connect with people, visibly and loudly showcase initiatives that reduce greenhouse gases emissions, nurture youth leaders, or spread the message by raising awareness through campaigns. I am convinced that your contributions will ensure that climate change solutions safely power our - and especially your - future.

The record-breaking extreme weather events causing chaos across the globe should be a wake-up call.

This is probably the most difficult task we have ever given ourselves, which is to intentionally transform the economic development model, for the first time in human history.

No architect should design buildings that import a huge amount of energy.
