Breath Of The Ocean Calls Fish

admin /7 March, 2008

Credit: Sean Lema, University of North CarolinaScienceDaily (Mar. 6, 2008) — An ocean odor that affects global climate also gathers reef fish to feed as they "eavesdrop" on events that might lead them to food.

Dimethylsulfoniopropionate (DMSP) is given off by algae and phytoplankton, microscopic one-celled plants that float in the ocean. Release of DMSP usually indicates either that tiny animals in the plankton are feeding on the algae, or that massive growth of algae — an algal bloom — has occurred, said Jennifer DeBose, a UC Davis graduate student and now a researcher with the National Oceanic and Atmospheric Administration’s Flower Garden Banks National Marine Sanctuary in the northwestern Gulf of Mexico.

Once released from the ocean into the atmosphere, derivatives of DMSP promote cloud formation, so clouds reflect more sunlight back into space and cool the Earth.

Solar Roads attract funding

The concept of using road surfaces to generate clean solar power is moving beyond the idea stage. Roads absorb heat from the sun every day and are usually free of sightline obstructions that could otherwise block the transmission of light rays. And if the roads built for cars and driving are partly to blame for global warming, why not make them part of the solution too?

Brusaw believes his system, if implemented from coast-to-coast in place of the tarmac on existing highways, could produce enough energy to meet the entire world’s electricity needs.

Idaho-based Solar Roadways is one of the trailblazers. Electrical engineer Scott Brusaw was inspired to start the company when he heard Caltech solar energy expert Nate Lewis suggest that covering just 1.7 percent of continental U.S. land surface with photovoltaic (PV) solar collectors could produce enough power to meet the nation’s total energy demand.

Brusaw put two and two together when he realized that the interstate highway system already covers about that much of the nation’s land surface, so he got to work designing a system that combines a durable and translucent glass road surface with PV solar collectors that could be wired directly into the electricity grid.

Solar Taxi halfway round the world

 Louis in Perth - halfway round the world Swiss Adventurer Louis Palmer started his trip around the world in his solar powered vehicle, the “Solartaxi”, on the occasion of the European Sustainable Energy Forum in Lucerne, Switzerland, on July 3, 2007. On 7th March 2008 he completed his journey across Australia, arriving in Perth from Sydney.

Louis Palmer travelled overland from the heart of Switzerland via 18 countries to the Middle East and India, from where he took a ship to his next destinations India and Indonesia – to reach Bali in time for the Climate Change Conference in early December, where the Solar taxi became a major attraction at the gates of the summit, where it served to give an emission-free lift to, amongst others, Peter Garrett, Australia’s new Minister for the Environment, Rajendra Pachauri, Chair of the Nobel Prize winning IPCC, and Bianca Jagger, President of the World Future Council, and Michael Blooomberg, City Major of New York.

Frogs could croak if global warming not fixed

admin /7 March, 2008

MONTREAL – Frogs have been around for millions of years, but if humans keep ruining the planet, these important members of the food chain face extinction, biologists around the globe are warning. One-third to one-half of the world’s 6,000 species of amphibians – frogs, toads and salamanders – could disappear if nothing is done, the Continue Reading →

Sweden aims to halve emissions in ten years

admin /7 March, 2008

Sweden will aim to get nearly half its energy from renewable sources by 2020 as part of an EU-wide plan, says Energy and Enterprise Minister Maud Olofsson. Olofsson said in Washington that Sweden had been tasked with increasing its share of renewable energy to 49 per cent from a current 40 per cent as part Continue Reading →
