Biodiversity comes up again and again here. And it is the Year of Biodiversity at the moment. But the importance of the topic does not seem to be adequately reflected in national and international policymaking agendas. Words help to build awareness - but it is action we need. And fast.

All the targets here above could be agreed if they weren't under the lead of the UN which is the most unfair institution of the modern history. The UN failed in dealing with the environment crisis and the world needs an independant environmental agency .

If more stable economic growth than has occurred since 2004 cannot be achieved, the prospects of summoning the political will to address the problems of climate change will be significantly reduced. The G20 needs to address the questions surrounding the financial crisis and the legal/economic structure which banking operates - under which limited liability companies borrow on a short term basis and lend on a long term basis. This structure carries the enormous benefit of achieving financial intermediation in which otherwise idle funds are allocated to investment opportunities. However it generates risks of panic withdrawals by institutional investors and private depositors – which states cannot afford to happen but also cannot afford to underwrite. Were these structural factors significant contributors to the financial crisis? If so, is there a way to restructure banking to reduce these risks whilst still facilitating effective financial intermediation? If the answer is yes in both cases, the G20 must face down opposition from interest groups and impose globally coordinated restructuring. If it is no in either, then the G20 must find a way to make more conventional regulation work.

China can't be the only non-littoral state weighing up its arctic options. Given the likely significance of the changed geography on global relations, it's only common sense.
