As someone who works in the energy industry - which is one of the key industries directly affected by climate change debates - I see a huge difference being made in the industry. If you meet someone from Europe, it is extremely hard find anyone who is not a huge proponent of renewables etc. Even in Asia, I see individuals (usually young ones) setting up renewable companies, installing renewables, lobbying AND CHANGING government policies. Things are changing. Not even "in my lifetime". More "in the time I have been in HK". Very fast. Sure, certain old fogies in the USA are trying to hold back the tide, but they are losing. And its being driven, on the whole, by young people. Ignore them at your peril.
