We owe our planet this climate march. But we also owe it – very faint – hope | Bill McKibben

Trump is the worst thing that could have happened to the planet. That's all the more reason to fight on - and celebrate even the smallest successes

There is no upside to the Trump presidency. To be in DC - I've come for Saturday's giant climate march - is to be reminded up close what all Americans have known for months: we've put the country in the hands of a man completely unequal to the task. A man so cluelessly over his head that he keeps telling reporters he's in over his head.

But if you want a few grayish linings to the dark-orange cloud, you can find them. In fact, the last few days have given those of us in the climate fight a few glimmers of light.
