Scientists say aerosols -- which encourage the formation of clouds, which in turn cool the earth -- may be changing ocean currents in ways that promote climate change.

"BANGKOK -- A floating mosque and golf course for the submerging Maldives islands. Amphibious homes in the Netherlands lifted to safety as waters surge beneath them. A hospital perched on 400 stilts to protect patients from Thailand's devastating floods and the encroaching sea."

"Why did the atmosphere contain so little carbon dioxide (CO2) during the last Ice Age 20,000 years ago? Why did it rise when the Earth's climate became warmer? Processes in the ocean are responsible for this, says a new study based on newly developed isotope measurements. This study has now been published in the scientific journal 'Science' by scientists from the Universities of Bern and Grenoble and the Alfred Wegener Institute for Polar and Marine Research in the Helmholtz Association."

"SYDNEY, Australia -- Earth Hour 2012 organizers are jubilant today after a satisfyingly successful global event on March 31. Lights went out at 8:30 pm local time as Earth Hour circled the world through a record 150 countries and territories, with 6,494 towns and cities participating."
