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.

Each building should produce as least as much energy as it's going to need, and have more to put on the grid. They should be using all of the natural light and natural heat.

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

We will move to a low-carbon world because nature will force us, or because policy will guide us. If we wait until nature forces us, the cost will be astronomical.

When you have a vision of where you need to go, it sounds utopian. But when you get to the tipping point, your understanding switches.

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.

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.
