One of the gaps in our international development efforts is the provision of global public goods - that is goods or conditions we need that no individual or country can secure on their own such as halting global warming financial stability and peace and security.

To re-embrace what I once loved about music has been a warming process for me because it's a good earned feeling now.

I was the type of guy that used to get up in the morning and go out and just out run everybody on the field without stretching or warming up or anything.

The war and terrorism in the Middle East the crisis of leadership in many of the oil-supply countries in the developing world the crisis of global warming - all these are very clearly tied to energy.

As this body of knowledge has evolved a much more critical job for researchers and scientists has evolved into explaining and educating policy makers and the public to the risks of global warming and the possible consequences of action or of no action.

Most North Americans know that human-caused global warming is real even if political leaders don't always reflect or act on that knowledge.

The most important thing about global warming is this. Whether humans are responsible for the bulk of climate change is going to be left to the scientists but it's all of our responsibility to leave this planet in better shape for the future generations than we found it.

I would like to see a future where artists think that they have a right to contemplate things like global warming.

With nine degrees of warming computer models project that Australia will look like a disaster movie. Habitats for most vertebrates will vanish. Water supply to the Murray-Darling Basin will fall by half severely curtailing food production.

Australia is the only island continent on the planet which means that changes caused by planet-warming pollution - warmer seas which can drive stronger storms and more acidic oceans which wreak havoc on the food chain - are even more deadly here.
