Climate Catastrophe Nearer, Al Gore Gives Us About 90 More Years
Former vice president Al Gore posted on his webpage that scientific studies of clouds and atmospheric pressure suggests that, “more likely than not, our planet will experience cataclysmic warming by the end of the century.” That would take mankind to the year 2100 before all hell breaks loose.

Seaweed-Threatened Corals Send Chemical SOS to Fish
When a killer seaweed touches a kind of spiky coral, the coral pushes a chemical panic button that brings small resident fish to the rescue.

Carbon Buried in Soil Will Rise Again
Carbon buried in soil rises again as carbon emissions, a clue to understanding past and future global climate change, U.S. and European scientists say. Researchers say that while earlier studies have found erosion can bury carbon in the soil, acting as a carbon sink or storage, part of that sink is only temporary. They estimated…
