Alastair McGowan is not only a renowned impressionist and comedian, he's also an Airplotter - and as one of the co-signatories of the deed on the land, he took the BBC down to have a look at the plot and have a chat about whether protest can make a difference.

An excellent film from The Ecologist exposing the tactics used against environmental protestors - from espionage and legal threats to news manipulation and violence:

Via Plane Stupid.

Brave activists from Greenpeace Australia climbed Queensland's Swanbank B coal-fired power station smokestack and unfurled an "Energy [R]evolution" banner. Temperatures have dropped to two degrees Celsius as they plan on spending the night on top in protest against the Australian government's push for coal.

This week's been busy for me, what with two demonstrations on two different campaigns. After the protest outside the Japanese Embassy, it was the Department of Transport's turn to welcome us. The government wasn't listening when we said NO to Heathrow's third runway last month. So this morning, we flashmobbed the Department of Transport and launched paper planes saying ‘NO AIRPORT EXPANSION' at transport secretary Ruth Kelly's office.

If you thought that the Terminal 5 flashmob and the Big NO! was all that would be done to oppose the third runway then you were wrong. On 3 July, get ready to flashmob once more and launch paper planes at the Department for Transport, and tell transport secretary Ruth Kelly why plans for the third runway must be scrapped.

Download a paper plane here and don't forget to write a message to Transport Secretary Ruth Kelly on it. The plan is to turn up outside Department for Transport (corner of Marsham St and Horseferry Road) at 11am sharp. If you've still got your red t-shirts from T5; even better but a paper plane is an absolute must. At 11.03 (precisely) those wearing ‘Stop Airport Expansion' t-shirts will reveal them, and then we will all launch our paper planes in the direction of the Department.

Actor Rula Lenska and journalist Rosie Boycott join other celeb mums in a vigil against Heathrow expansion in Parliament Square

As the date for the government's decision on Heathrow's third runway hurtles towards us (they'll be deciding in June or July, we think), a whole gamut of voices has been speaking out against the agenda for airport expansion that will destroy our chances of slowing climate change.

At the risk of sounding like a bad joke, an actress and a bishop (OK then, an archbishop) have both joined the fray, along with several celebrity mums and the head of the Sustainable Development Commission. Eclectic, eh? They're all calling on the government to shelve its plans for airport expansion.

We had Fossil Fool's Day last week with plenty of action around the country to highlight the dangers posed by coal, but the dreadful punning doesn't stop there. Continuing the theme, next Tuesday is April Biofool's Day which admittedly falls on the 15th rather than the 1st, but that's because the Renewable Transport Fuel Obligation (RTFO) - which will overnight increase our consumption of biofuels - begins to make its presence felt.

On the day, the good folks at Biofuelwatch and the Campaign against Climate Change are organising a protest outside the home of a certain Mr Gordon Brown, Number 10 Downing Street. You can join the crowds outside Number 10 from 6pm and further details are on the websites of both organisations. If you can't get there, you can still do something - write to transport secretary Ruth Kelly with your concerns about this rush towards biofuels.

Meanwhile, concerns about biofuels are rising up the political ladder, as last week UN secretary-general Ban Ki-moon called for a review on global biofuel policies. Our government currently has the indirect impacts with biofuels under review but the results aren't due for some time, and certainly not before Biofool's Day next week.

Thousands joined hands to surround Aldermaston base on Easter Monday

On the Easter weekend of 1958 - a few weeks after the birth of CND - thousands of people braved the icy weather and marched from London to the nuclear weapons factory at Aldermaston in Berkshire to protest the building of nuclear bombs. The march marked the birth of the peace movement in Britain.

Sadly, 50 years on, the peace movement is needed as much as it ever was; last year, our government (which counts many former CND members among its numbers) voted to replace Trident, and to lock the world into at least another 50 years of nuclear bombs. Despite the rhetoric of Brown's recent national security strategy (he wants "to free the world from nuclear weapons", apparently), £5 billion is being poured into building new facilities at Aldermaston to design new nuclear bombs - most likely in contravention of the Nuclear Non-Proliferation Treaty.

Kingsnorth in Kent is to be the main focus of this year's Camp for Climate Action. From 4th to 11th of August climate activists will gather at the site of E.On's proposed new coal-fired power station, the first to be built in the UK for 30 years.
