So in the economic outlook that we just launched today, we addressed the issue of it’s we can't do anything on climate change right now.

We can't have policy because the global economy is fragile. And we address that head-on in one of the chapters, second chapter and as well as in the main text.

It said, you know, there are a lot of things that we can do now are actually pro-growth and pro-climate.

And we give a lot of examples about what countries have already done that have been pro-growth through their economies and pro-climate.

So that's the first thing that I think we have to get off the table that climate change is... (It’s the anti-growth)

It’s the anti-growth, now the anti-science that's a really tough one and I think everybody who's going to be in Paris is pro-science.

Should there be people there to push back and France seems to me that's one of the big questions is everybody's on the same page in Paris right?

I think everybody's on the same page with regard to the science, they're not on the same page with regard to the policy but you know,

I think that there's the French have been working very hard behind the scenes to get an agreement, we're focusing on incentives,

getting the prices right and then following it on the policies.

If we could at least get another factor which is complexity. There is such complexity of existing policies in many countries that simply, simplifying them would get us a long way towards an improvment.
