2010 has seen - at least in the first half of the year - a fair bit of pessimism on climate change action, particularly government policy. But, with the US National Academy of Science saying warming is a settled fact, many governments have continued to act regardless of slow progress on a global agreement.
Scotland's First Minister Alex Salmond is a good example. He says green energy is a pivotal turning point in human history. Scotland has committed to 80% green electricity by 2020 and reportedly 100% by 2025. Technologies include offshore wind and the world's largest tidal turbine.
The Scotland's overall emissions cut target is 42% by 2020. Recent research finds a 40% European wide cut is achievable by 2020. And the payoffs are substantial with HSBC estimating a global low carbon economic opportunity of up to USD 2.7 trillion by 2020.
