Maybe no other speech on climate change was so expected. Climate Change activists (called Climate Hawks too) were quite disappointed with Obamas first term and not so happy with seconds beginning but this speech last week, changed this point of view as explained by Joe Romm, and many others. It was even mentioned in European newspapers, and of course, by skeptics.
After one week, the positive opinions, mixed with others asking more action.
I found Obama’s speech inspiring as the great speaker he is and important considering climate change debate in USA. Clearly it is not enough for the change we need from americans from their huge CO2 emissions (three times those of China or even some European countries). It is far for explaining how to reduce the americans 18 Tons CO2 per capita to the more or less 1 Ton target, but it was a first step and no long way has been done without starting step by step. It did not explain the scope of the change needed but it attacked the weakest part of the problem: the acceptance of the problem and the need to act. And one of the virtues of americans is that they are able to act fast once they are convinced. I hope it is so. We all need that, China and USA are 40% of the emissions in current world.
