That's why people are standing up again to fight the Keystone pipeline in Nebraska and South Dakota and Montana. Everyone is well aware of what this industry is about. It engages not only in those kind of practices, polluting people's water, but it has polluted our political life now for a quarter century.

Remember...this year has already seen more billion-dollar weather-related disasters than any year in US history. Last year was the warmest ever recorded on planet Earth. Arctic sea ice is near all-time record lows. Record floods from Pakistan to Queensland to the Mississippi basin; record drought from the steppes of Russia to the plains of Texas...This is what climate change looks like in its early stages.

If it's wrong to wreck the planet, it's wrong to profit from the wreckage.

But the truth is that we could win every other fight that we face and if we lose the climate fight, the other victories will be pyrrhic. I don't think even people who are worried about climate change quite understand the scale and speed with which we're now shifting the planet.

Certainly, packets of sea ice, in say the Arctic, which have failed to fully reform in the last couple of years.

I think that some of it is electoral - helping candidates that are willing to take dramatic actions, not just to say a few words about how climate change might be a problem.

I guess the underlying principle might be, don't make it too easy for them to stereotype you.
