Climate change leaves us no time for talking without action

What can we expect of the United Nations Climate Change Conference that opened in Katowice, Poland, on Monday?

We sincerely hope that it will no longer serve up just a diet of rhetoric and instead produce a down-to-earth action plan in which all countries do their bit.

But that requires the major countries to demonstrate the political will to agree on ways to implement the promises they made in the 2015 Paris treaty to limit temperature rises to avert runaway global warming.
