when it's not either/or

Mike Bartlett's play Earthquakes in London, opens at the National tonight. It's about climate change. Bartlett tells the Financial Times that it's an 'either/or' subject, which of course it isn't:

It’s very difficult to find objective truth about climate change. Everyone has a reason to emphasise one thing or the other. Either it’s a huge catastrophe and it’s really going to hit within a hundred years. Or we’re fine. It could be either way.

Maybe the characters talk more sense.
