Global Warming 2020

"We should work to eliminate the use of tasty fish for livestock production. It's a waste," says Daniel Pauly, one of the researchers. "Plus, it is not what pigs or chickens naturally eat. When is the last time you saw a chicken fishing?" (Credit: iStockphoto/Tony Campbell)

Global Warming News : Finding alternative feed sources for chickens, pigs and other farm animals will significantly reduce pressure on the world’s dwindling fisheries while contributing positively to climate change, according to University of British Columbia researchers.

“Thirty million tons — or 36 per cent — of the world’s total fisheries catch each year is currently ground up into fishmeal and oil to feed farmed fish, chickens and pigs,” says UBC fisheries researcher Daniel Pauly, co-author of the Oryx: The International Journal of Conservation article, recently published online.

“Meanwhile, 25 per cent of infants in Peru — which produces half of the world’s fishmeal using anchovies — are malnourished,” says Pauly.

In the Oryx article, nine of the world’s leading fisheries and conservation researchers — including four from UBC — reviewed the effectiveness of past conservation campaigns and propose new strategies to effect swifter and larger-scale changes.

Rising carbon dioxide emissions cannot be stabilized unless the world's economy collapses or society builds the equivalent of one new nuclear power plant each day, according to a University of Utah scientist. (Credit: iStockphoto/Mark Aplet)

Global Warming News : In a provocative new study, a University of Utah scientist argues that rising carbon dioxide emissions — the major cause of global warming — cannot be stabilized unless the world’s economy collapses or society builds the equivalent of one new nuclear power plant each day.

“It looks unlikely that there will be any substantial near-term departure from recently observed acceleration in carbon dioxide emission rates,” says the new paper by Tim Garrett, an associate professor of atmospheric sciences.

Garrett’s study was panned by some economists and rejected by several journals before acceptance by Climatic Change, a journal edited by Stanford University climate scientist Stephen Schneider. The study will be published online the week of November 23.

Global Warming News : A new study provides “incontrovertible evidence” that the volcanic super-eruption of Toba on the island of Sumatra about 73,000 years ago deforested much of central India, some 3,000 miles from the epicenter, researchers report.

The volcano ejected an estimated 800 cubic kilometers of ash into the atmosphere, leaving a crater (now the world’s largest volcanic lake) that is 100 kilometers long and 35 kilometers wide. Ash from the event has been found in India, the Indian Ocean, the Bay of Bengal and the South China Sea.

Global Warming News : Green Heating And Cooling Technology Turns Carbon From Eco-villain To Hero

Carbon is usually typecast as a villain in terms of the environment but researchers at the University of Warwick have devised a novel way to miniaturise a technology that will make carbon a key material in some extremely green heating products for our homes and in air conditioning equipment for our cars.

Most domestic heating and automotive air conditioning requires a lot of energy. Domestic space heating and hot water account for 25% of energy consumption in the UK. Across the EU, vehicle air conditioning uses about 5% of the vehicle fuel consumed annually, and within the UK it is responsible for over 2 million tonnes of CO2 emissions.

To combat global warming, new technologies to reduce these emissions are vital. Researchers at the University of Warwick have been working on practical solutions for many years and are now developing new energy saving technologies. .. read FULL STORY >>
