Your first question provides me with an opportunity to say something I think is blindingly obvious, namely, that all governments everywhere must make climate change a priority issue, even if it's difficult to do in times of economic hardship, even if it requires cooperation with other governments that might be hard to manage, and even if there's little feedback on progress in the lifetime of a Parliament or a politician or a CEO of a large company.
This problem is large. It appears intractable. It's frustrating. You can hardly feel any reward for making progress in it, but it defines what government is for. It doesn't make any difference what a government's politics is: climate change has nothing to do with left or right. How you respond to it does, but understanding the issue does not.
I've been working on this for over 20 years, and I remember vividly the United Nations General Assembly on Global Environment in November 1989, when Margaret Thatcher said that climate change science is so clear, the need to act so obvious, that we shouldn't be squabbling over who pays for it.
