It is critical that the world captures every last bit of energy efficiency, if we are to reduce greenhouse gas emissions enough to keep below dangerous rises in temperature. I am pleased that this important new study shows how information and communication technology can play an essential role in saving energy. Now we need more and effective government policies that reward such action and penalize delayed responses.

DEMAND, PURCHASE & USE LOW CARBON PRODUCTS AND SERVICES. MAKE LOW CARBON SEXY!

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."

We're going to get to the point where we ask how the hell we put up with high carbon for so many years. You thank your lucky stars, because you are seeing this transformation in your lifetime. You are going to tell your children and your grandchildren you saw this whole thing in front of your eyes.

The record-breaking extreme weather events causing chaos across the globe should be a wake-up call. The transition to a low-carbon economy will be much more painful if we wait until there is a climate crisis before recognising that more than half of the world's fossil fuel reserves will have to remain in the ground.

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.

The fact is, when you talk to people, they know that something weird is going on, particularly people who are connected to the land or the water. They can see it. What perhaps is not so evident to them, unfortunately, is what the solution is. But whether they call it climate change or not, it doesn't matter. The point is, they can see there's something fundamentally weird going on here.
