Something that happened a few weeks ago but has slipped through the net is that Sainsbury's has announced an improved policy on light bulbs. By committing to phasing out those wasteful incandescent bulbs by 2010, they join Asda and Morrisons (who also recently shifted their stance) further up our league table. That still only gives them a D, but it leaves three supermarkets lower down - Tesco and the Co-op at E and Somerfield a disappointing F.

Meanwhile, there's been no further word from wooden spoon winners Woolworths since their CEO's response to our day of action, but we're still working on them. You may have been invited to sign a 'Seize the Light' flag outside you local branch, as groups of Greenpeace volunteers (like the Blackburn group pictured) have been collecting signatures to show Woolworths that their customers want them to help everyone improve their energy efficiency by getting rid of out-dated, inefficient light bulbs.

If you haven't emailed Woolworth CEO Trevor Bish-Jones, now's the time - everyone who's done so has received a personal response, and you could be one of those lucky people. Or if you fancy a bit of flag-signing, contact your local Greenpeace volunteer group and find out how you can help everyone make the switch.

It was almost too good to be true. When the Brazilian government announced last week that deforestation rates in the Amazon had dropped for the third year running, it was certainly a cause for celebration. But it now transpires that one of the government's own agencies is colluding with logging companies so they can gain access to areas of high-value timber that would otherwise be off limits.

According to the update board in the climate camp info tent, the various groups of protesters have had various degrees of success, not least a troupe of clowns. They're among the campers who have made it to the BAA offices at Heathrow, although apparently they've been penned in by police. Other teams have also made it, despite a heavy police presence, and 250 are currently coralled behind the BAA building. Others remain at large. Elsewhere, a group have been in Sipson village marking out where the planned third runway will be.

It's a shame the New York Times only allows subscribers to see their stories online (don't get any ideas, UK press moguls) because there was an absolute corker in yesterday's edition that's been sent round on email. Al Gore, when talking to columnist Nicholas Kristof, advocated a programme of direct action to tackle climate change:

"We are now treating the Earth's atmosphere as an open sewer," [Mr Gore] said, and (perhaps because my teenage son was beside me) he encouraged young people to engage in peaceful protests to block major new carbon sources. "I can't understand why there aren't rings of young people blocking bulldozers," Mr. Gore said, "and preventing them from constructing coal-fired power plants."

Is this the first sign of a change for the man who used to be the Next President of the United States? Will he shake off the mild-mannered lecturer schtick, going underground to lead troops of young activists into confrontation with police, power companies and politicians? Will there be a resurgence of grass-roots politics where our elected officials through off the trappings of state to take their lead from the people?

Nah, maybe not. Besides, I don't think a beret and beard would suit Al. Still, Kristof ended his column with a rather salient point:

Critics [of climate change] scoff that the scientific debate is continuing, that the consequences are uncertain - and they're right. There is natural variability and lots of uncertainty, especially about the magnitude and timing of climate change.

In the same way, terror experts aren't sure about the magnitude and timing of Al Qaeda's next strike. But it would be myopic to shrug that because there's uncertainty about the risks, we shouldn't act vigorously to confront them — yet that's our national policy toward climate change, and it's a disgrace.
