global warming tipping point

Eminent biologist Professor Frank Fenner, who helped to eradicate smallpox, recently made the dire prediction that humans will probably be extinct within the next 100 years due to overpopulation, environmental destruction and climate change.

Swedish researchers are working on an underwater kite that could provide a low-cost and low impact method for tapping into the energy of the ocean. Swedish start-up Minesto has obtained $2.5 million to start testing the kite in Northern Ireland next year. The kite, called Deep Green, is able to capture tidal energy at 10 times the speed of the…

This is a really good sign that the US may finally be taking renewable wind power seriously. The Cape Wind project has been approved yesterday allowing for the construction of 130 turbines at Horseshoe Shoal south of Cape Cod. This marks the first of a long, incremental, and sometimes painful shift toward a large-scale clean energy future. This…

A Harvard physicist has thought up a novel and very strange way of turning back global warming: pumping massive quantities of microbubbles into the oceans which would have the effect of increasing their reflectivity. By reflecting back more sunlight, the oceans will start to cool. Sound like science fiction? Harvard physicist Russell Seitz…

An international team of 30 scientists have determined from extensive research that there are nine factors of tremendous importance that must remain within certain limits if the Earth is to dodge environmental catastrophe. The nine factors, as determined by the group, are biodiversity loss, land use, freshwater use, nitrogen and phosphorus cycles,…
