ENVIRONMENT: Planetary Check-Up Starts With the Oceans

If continents are the Earth's sturdy bones and the atmosphere its thin skin, then the oceans are its heart, circulatory system and blood. And despite the crucial role played by the oceans in the health of the planet, and to our own health and well-being, there is little monitoring of ocean health.

CLIMATE CHANGE: Kyoto on Track, Despite Some Slackers

Total greenhouse gas emissions of 40 industrialised countries rose to a near all-time high in 2005, but the Kyoto Protocol will still exceed its reduction targets, a United Nations agency said two weeks before political leaders meet in Bali, Indonesia to begin negotiations on a new and more aggressive treaty to battle climate change.
