The climate emergency is the defining crisis of our time.
 
We are in a race against time -- and we are losing.
 
There is a growing tide of impatience – especially among young people -- with global inaction.
 
We need more ambition from all – governments, cities, businesses, investors, and people everywhere.
 
So, I am pleased you are launching TED Countdown.
 
Your influence and ideas can help accelerate momentum for a carbon-neutral world by 2050.
 
That is the only way to avert the worst impacts of global heating.
 
We have the tools, the science, and the resources.
 
Let us now get into this race with political will and energy.
 
To do anything less will be a betrayal of our entire human family and generations to come.
 
Thank you.
