New EPA chief ready to give California new car rules of its own?

January 15, 2009

Environmental Protection Agency chief-to-be Lisa Jackson said science would be her guide on policy – and that may mean California is in the driver’s seat on setting new global-warming-style regulations on cars. (Not to mention the nearly 20 other states ready to follow in its footsteps.)

On Antarctic safaris, remember to bring a microscope

January 13, 2009

Many people hope to come back from a wildlife safari with close-up pictures of lions or elephants – this picture below is my best attempt from a search for the largest land animals in Antarctica.

California takes leap of global warming faith

December 12, 2008

California is either about to bankrupt all its businesses, or it’s unleashing a green revolution.

What hope for U.N. climate talks in Poland?

December 1, 2008

This week the U.N. leads a new round of global climate talks, in its 14th meeting since the world signed up to the convention on climate change in 1992.

Greenhouse gases: saints, villains or future saviours from an Ice Age?

November 13, 2008

 It’s not often that greenhouse gases spewed out by human activities get praise as potential saviours of the planet in a leading scientific journal — they’re normally viewed as villains for causing global warming.

Smoke and mirrors to slow global warming?

October 27, 2008

With worries about recession in many countries, does it make sense to try out some more radical ideas for fighting global warming, like placing mirrors in the sky to block the sun or fertilising the oceans to soak up greenhouse gases?

Cyclones’ silver lining: they may slow global warming

October 20, 2008

A Filipino resident wades across a flooded area after Typhoon Mindulle hit Baguio City, north of Manila, July 1, 2004. At least 16 people were killed when Typhoon Mindulle hit the country on Wednesday, packing peak winds of 190 km per hour near the center and gustiness of 230 kph, cut power and telecommunications lines.

Antarctic ice expands — global warming at work?

September 12, 2008

Adelie penguins in Antarctica are photographed in this January 18, 2005 file photo. The pesticide DDT, banned decades ago in much of the world, still shows up in penguins in Antarctica, probably due to the chemical’s accumulation in melting glaciers, a sea bird expert said on May 9, 2008.

A Silver Bullet or just ‘Greenwash’?

September 9, 2008

A truck with a CO2 tank stands in front of the mini plant “Schwarze Pumpe” before the first official run in Spremberg SeptemberCan carbon capture and storage (CCS) save the world?

Is this the silver bullet everyone’s been waiting for? Or just pie in the sky? Is capturing and storing carbon dioxide the technology breakthrough to cut greenhouse gas emissions without getting in the way of economic growth and industry’s “addiction” to fossil fuels? Or is it just a “greenwash” — a token gesture by some of the utilities responsible for so much of the world’s CO2 to try to persuade an increasingly green public that the great emitters are doing something to fight climate change?
