Unfortunately, very few people in America know the real name of Hurricane Katrina because the coal and oil industries have spent millions of dollars to keep the public in doubt about the issue.

Climate change is not an environmental problem. It is a civilizational problem. Climate change is not just another issue. If it is not addressed in very short order, it will swamp every other issue facing us today

Our planet has run out of patience. So has our sense of justice. It is time to step it up - and up - and up - until we reach the only goal that really matters: peace among people and peace between people and nature.

Stormy Weather is really wonderful - it ought to be required reading for everyone who is concerned about our planet's climate, beginning in every high school in the country.

Climate change is not just another issue. It is the issue that, unchecked, will swamp all other issues. The only hope lies in all the countries of the world coming together around a common global project to rewire the world with clean energy. This is a path to peace -- peace among people, and peace between people and nature.

Ultimately, I believe - because energy is so central to our lives - that a common global project to rewire the world with clean energy could be the first step on a path to global peace and global democracy - even in today's deeply troubled world.

The Aedes aegypti mosquito, which spreads dengue fever and yellow fever, has traditionally been unable to survive at altitudes higher than 1,000 meters because of colder temperatures there. But with recent warming trends, those mosquitoes have now been reported at 1,240 meters in Costa Rica and at 2,200 meters in Columbia. Malaria-bearing mosquitoes, too, have moved to higher elevations in central Africa, Asia, and parts of Latin America, triggering new outbreaks of the disease.
