Another View on Gas Drilling in the Context of Climate Change

I’ve received a “Your Dot” contribution on gas leaks and global warming fromLouis A. Derry, an associate professor in the earth and atmospheric sciences department at Cornell University. It’s a critique of one element in “Gangplank to a Warm Future,” an Op-Ed article by Anthony R. Ingraffea, a professor of engineering at Cornell who is a prominent foe of expanded gas drilling using the bundle of methods commonly known as “fracking.”

Arctic methane ‘time bomb’ could have huge economic costs

Scientists say that the release of large amounts of methane from thawing permafrost in the Arctic could have huge economic impacts for the world. The researchers estimate that the climate effects of the release of this gas could cost $60 trillion (£39 trillion), roughly the size of the global economy in 2012. The impacts are most likely to be felt in developing countries they say.

Trading Halt Shows UN Carbon System in Jeopardy: Energy Markets

An unprecedented freeze in United Nations carbon trading is fanning speculation the five-year-old market designed to combat greenhouse-gas emissions in poor countries is in danger of becoming superfluous.

Not a single UN Certified Emission Reduction, or CER, changed hands on July 22 and July 23, according to data from ICE Futures Europe, keeping the market on course for the lowest monthly aggregate volume since March 2008. The 14.3 million tons of offsets bought and sold this month compares with the record 211 million tons traded in October and an average 52 million over the past 12 months.

Five of big six energy companies drop green tariffs

Five of the “big six” energy companies have dropped their policies of offering green tariffs to new customers, in a move which green campaigners fear could undermine the national drive to tackle climate change.

Npower announced earlier in July that it was scrapping its domestic green electricity tariff for new customers, while EDF, E.ON, SSE and Scottish Power are also no longer offering a domestic green tariff for those wishing to switch. With all but one of the big six energy companies offering no 100% renewably sourced electricity tariff to new customers, the choice for consumers who are keen to support green electricity has been drastically reduced.

Green Growth – overcoming India’s environment challenges to promote development

Towards a Green India

Although the past decade of rapid economic growth has brought many benefits to India, the environment has suffered, exposing the population serious air and water pollution.
A new report finds that environmental degradation costs India $80 billion per year or 5.7% of its economy.
Green growth strategies are needed promote sustainable growth and to break the pattern of environmental degradation and natural resource depletion. Emission reductions can be achieved with minimal cost to GDP.

Rapporto ISPRA: Ambiente in bianco e nero nel Bel Paese

Diminuiscono le emissioni e cresce la superficie boscata ma nelle città si continuano a sforare i livelli di inquinanti, tra cui PM10 e benzo(a)pirene. E oltre 6 milioni di italiani vivono in zone a rischio alluvione.

È la fotografia scattata dall’Annuario dei Dati ambientali ISPRA 2012, presentato oggi a Roma.
