...Saturday 28th March 2009 at 8:30pm.

Yes folks it's nearly time for Earth Hour again. Earth Hour takes place on Saturday night at 8:30pm local time so whether you're in  Sydney, London, New York or Los Angeles at 8:30pm your time it's time to switch the lights out.

President Obama is not hanging about is he? Yesterday he announced America's intent to provide global leadership on climate change (Gordon Brown, are you listening?) and to allow states to set their own vehicle emissions targets for vehicles.

Ministers will apparently give the go-ahead for the controversial third runway at London's Heathrow Airport later today according to the BBC.

Despite open opposition from around 50 of the Government's own MPs, opposition MPs, environmental groups, concerned citizens and residents of the houses in the path of the runway, the announcement will be made today under the provision that the expansion is within strict environmental parameters.

In the weekly address from the President-Elect, Barack Obama, on Saturday 10th January, you could be forgiven for hoping he was talking just about environmental issues when he stated:

These numbers are a stark reminder that we simply cannot continue on our current path.

Rising temperatures or sea levels? Disappearing rainforests? Breakup of glaciers or endangered species? He continued:

It’s not too late to change course – but only if we take immediate and dramatic action.

I'll admit it - I'm a petrol head. That may sound like utter hypocrisy for a man who runs a green website, but it's the way I was brought up.

Like all boys I've always loved cars and when I had the opportunities to buy fast cars I did so. I still have them. One hasn't done a single mile in 6 years and the other does over 30 miles to the gallon. I also do below average mileage, the cars are old but well-maintained and so I probably contribute far less CO2 into the environment than your average motorist, maybe half. That's still a good score.

Oh dear. It looks like George W Bush wants to rush through environmentally damaging changes to the Endangered Species Act. Clearly the man has no shame, no brain and absolutely no concern for the natural world in any shape or form.

This looks like it could be his last parting shot, a f**k you, if you will, to the people that have watched his tenure with continued astonishment.

If you're in the oil, mining or logging industries, it looks like your old buddy Dubbya has handed you the keys to the wilderness on a silver platter.

I missed this story a few days ago but somebody on a TV political show mentioned it today:

As he left the G8 summit George W Bush said "Goodbye from the world's biggest polluter", raised a fist in the air and smiled that smug non-compliant grin like only George W Bush can.

Goodbye and good riddance.

The G8, the group of 8 industrialised nations (Britain, Canada, France, Germany, Italy, Japan, Russia and the United States) have made a decision to go green.

Actually it's a decision to wholeheartedly go green by... cutting emissions by 50% and not the 100% you might expect.

And despite the rapid rate of deterioration in so many (eco, social, political) systems in the world, the G8 have given themselves a nice and easy 42 years in which to achieve this.

Britain's unelected leader (at least, unelected by the people in a democratic general election), Prime Minister Gordon Brown, is apparently the only head of government at an oil summit in Jeddha at the moment, discussing with the Saudi King Abdullah the future of oil.

The BBC's speculatively-titled story "Chancellor looks to green budget" is pretty thread-bare, starting with the opening line:

Green taxes and measures to help people struggling to pay energy bills are likely to be among changes in the chancellor's first Budget on Wednesday.

It goes on to speculate that the chancellor, Alistair Darling, might put a levy on larger vehicles like people carriers, putting their price up by £2000.

And that's it!
