I still suspect I may have fallen down a rabbit hole but apparently it's true. Two weeks after formally telling the world they're opposed to a third runway at Heathrow, the Tories have issued an extraordinary warning to companies. Don't get involved in any contracts to build the third runway, they're saying, because we're "absolutely determined" to stop the project going ahead. (Oh, and they're opposed to a second runway at Stansted too.)

With the Rainbow Warrior on her way to the UK, we thought we'd put together a slideshow to share a few of the highs - and lows - of her remarkable history. Our flagship, the Rainbow Warrior has travelled from South America to the South Pacific, the Antarctic to the Atlantic - an icon for environmentalists around the globe.

The ship coming to the UK is of course the Rainbow Warrior II; the original vessel was sunk in 1985 by French government agents trying to foil protests at their nuclear weapons testing in the Pacific. (The ship's name was inspired by a Native American prophecy which foretells a time when human greed would make the world sick, and warriors of the rainbow would come together to save it.)

There've been two new blows to the UK's prospects of tackling climate change in the last couple of days.

First, City Airport got permission to increase flights to and from the airport by up to 50 per cent - despite the presence of dozens of flashmobbers registering their opposition outside Newham Town Hall (where the decision meeting was taking place), and local planners, teachers and campaigners from a number of organisations inside the hall. And despite the fact that the airport representatives couldn't and didn't even try to answer the accusations that they'd lied and their noise figures were inaccurate.

She's our world famous flagship, she's helped to win Greenpeace campaigns across the globe and now she's coming to the UK to persuade Gordon Brown to Give Coal the Boot.

The Independent Climate Change Commission has warned the government that it should cut all greenhouse emissions by 80 per cent by 2050 to tackle climate change.

In itself, this isn't particularly surprising; scientists have been recommending this for some time. More interesting - and very welcome - is that the commission wants to include aviation and shipping in the target. That means, for once, that 'all greenhouse gas emissions' pretty much means 'all greenhouse gas emissions'.

Big news from this morning's Cabinet reshuffle: Gordon Brown has created a new department for climate change and energy, and Ed Miliband has been appointed its head.

This is, potentially, fantastic stuff. Until now, one department has been dealing with climate change and another - the department for business (DBERR) - with energy. This entirely nonsensical division hamstrung any chances of a coherent, low carbon energy policy and kept business and environmental interests at perpetual loggerheads. No prizes for guessing who usually won.

Given that we have the best renewable resources in the European Union, the fact that Britain languishes near the bottom of the European renewables league table is pretty humiliating.

On Monday though, the International Energy Agency added insult to injury. Britain's renewables strategy, it said, is 'ineffective' and 'very expensive'. The agency's new report (published here, but you have to pay) ranks Britain 31st out of 35 countries - "including all the major industrial nations such as the US, Germany and China" - in its green energy cost league. And our 'renewables effectiveness', it says, is a paltry three per cent.

You might remember that, 18 months ago, we set up ticket exchanges at airports across the country, and called on British Airways to show genuine leadership instead of launching new, unnecessary short haul routes that just add to the huge threat to our climate caused by runaway aviation growth.

Interesting news from our colleagues in Turkey, where 37 activists from Greenpeace and Global Action Group were arrested after protesting against nuclear energy last week.

The Turkish government has been busily trying to find a supplier for its first (of many, potentially) nuclear plant. But the plans have been stopped dead by... investors. Of the six companies supposedly interested in the contract, only one made a bid. And, without competition, Turkish law prevents the government from issuing the tender for a new nuclear plant.

We've been hearing likely sounding noises for a while now but today, the Conservatives have formally announced that they'd say no to a third runway at Heathrow, and yes to a high speed rail link between London, Birmingham, Manchester and Leeds instead.

And so I find myself a bit befuddled to be wholeheartedly agreeing with a Tory party spokesperson, Theresa Villiers. She said:
