I’m mid-way through packing up ready to leave uni tonight - but there’s so much going on in Copenhagen, I thought I’d write a really quick one anyway.

First up, check out this rap by the incredible Josh from the UK Youth Delegation on the streets of chilly Copenhagen.

Second up, some news.  Apologies for the conciseness - I’ve got to go catch a train soon, but I’ll write you a super-blog tomorrow to make up for it.

Status of the talks: still no agreement in sight.

Heads of government from more than 115 countries are going to take over the talks tomorrow.

Generally, the whole place seems pretty chaotic.  The UNFCCC who’ve organised the conference allowed 40,000 people to register for a venue of 15,000.  Result: thousands of people left queuing in the cold on Tuesday, unsure why they weren’t being let in.  Loads of NGOs and observers are now being denied entrance - pretty frustrating for people who’d booked travel and hotels etc and are now facing a wasted trip.  Most of the youth delegates have been blocked from entering too.  But even for those inside the conference centre, it’s getting increasingly difficult to work out what state the negotiations are in, with more and more meetings being held behind closed doors.

Some youth delegates have staged a sit-in in the conference centre itself.  They were pushed around by the security guards but didn’t face nearly such an ordeal as protestors outside the conference centre - there was a massive “Reclaim Power” protest yesterday, at which the police were being very heavy-handed - people under arrest were forced to sit for hours on the freezing ground, without being permitted access to toilet facilities, water or medical attention.

Hilary Clinton has arrived in Copenhagen and pledged US support for a $100 billion climate fund to help poorer countries adapt to the impacts of climate change.

And developing countries appear to have won their battle against replacing or downgrading the Kyoto Protocol, which was created in 1997 and is currently in force.  The thing with Kyoto (as you may well know) is that not all countries ratified it - notably the USA.  So since then, alongside the Kyoto negotiations there have been other negotiations which have included the USA.  The downside of keeping Kyoto is that its name is hugely unpopular with the US public so it would be harder to get the US to sign up to a new version of the old treaty.  However, a big plus of Kyoto is that it acknowledges “common but differentiated responsibilities” - that means it says those who’ve polluted most should do most to clean up the mess.

Ok, so this was quite long in the end!  All eyes on Copenhagen tomorrow, on the last day of talks.
