The world as we knew it is coming to an end, and it's up to us how it ends and what comes after.

It's the end of the age of fossil fuel, but if the fossil-fuel corporations have their way the ending will be delayed as long as possible, with as much carbon burned as possible.

If the rest of us prevail, we will radically reduce our use of those fuels by 2030, and almost entirely by 2050.

We will meet climate change with real change, and defeat the fossil-fuel industry in the next nine years.

If we succeed, those who come after will look back on the age of fossil fuel as an age of corruption and poison.

The grandchildren of those who are young now will hear horror stories about how people once burned great mountains of poisonous stuff dug up from deep underground that made children sick and birds die and the air filthy and the planet heat up.

We must remake the world, and we can remake it better.

The Covid-19 pandemic is proof that if we take a crisis seriously, we can change how we live, almost overnight, dramatically, globally, digging up great piles of money from nowhere, like the 3tn dollars the US initially threw at the pandemic.

The climate summit that just concluded in Glasgow didn't get us there, though many good and even remarkable things happened.

Many leaders, they even hardly deserve the term "leader", were held back by the vested interests and their own attachment to the status quo and the profit to be made from continued destruction.
