Brazil Nuts (and Others)?

Somewhat predictably, the UN Climate Change conference in Poland has finished without a completed agreement on how to regulate (or even count) the required reductions in greenhouse gas emissions made by different countries to reduce the chances of global temperature rises above the 'safe' level (https://www.theguardian.com/environment/2018/dec/15/un-climate-change-talks-postpone-contentious-issues-with-draft-agreement). The change in the attitude of the new Brazilian government is particularly problematic (they have even withdrawn their offer to host the next meeting which will now be in Chile). The prognosis continues to be poor.
