Live-from Lima - Ed-Davey writes from the climate change talks

I'm half way through my third day at the Lima UN climate change talks and the negotiations look set to go to the wire this weekend.

But that's not because there's some crisis in the global talks - it's because these are the most technically complex and politically challenging global negotiations ever. To make global agreements on how we move our carbon world to a low carbon world is an extraordinary task.

And the good news is that - thanks to Liberal Democrats in government - we come to the talks with a good story to tell - one of leading through example. Of walking the walk, and unlike some, not just talking the green talk. You may have read that Michael Gove prevented the Tory Climate Change Minister from attending the talks and I will leave it to him to explain his actions.

Our record is impressing many. Since 2010 we've more than doubled the amount of electricity generated from renewables. The UK led the way on securing a challenging EU-wide target to reduce emissions. And the UK's long planned pledge of £720 million towards the Green Climate Fund will help developing countries adapt to climate change and decarbonise.

Overall the main objective of these talks is to 'keep the eye on the prize'. The prize is a global and legally binding emissions reduction target at next year's Paris talks. So what needs to happen over the next few days is momentum, with the building blocks being put in place to show we're still firmly on track for next year.

For the Lima talks, that means 3 things. First we need an agreement that allows us to compare apples with apples. The bottom line is we need countries to come forward with information about their plans to reduce emissions so that all commitments can be compared, then monitored and verified. Second, we need to see pen put to paper and agree the draft elements of text to start the detailed negotiations necessary ahead of the 2015 Paris summit. Lastly as a new deal would only take effect in 2020 we need to hear more from some countries about upping their carbon cut commitments before then.

With 195 countries involved, that's easier said than done. So the next few days will see tough negotiations on text. I'll keep you updated with the progress that we're making, and for an hour tomorrow I'll be on Twitter answering any questions you may have. The session starts at 3:30pm UK time and you can submit questions before or during the session using #BackClimateAction
