Making a difference. That's what made me travel thousands of miles from my home to Bali in Indonesia. I was there with Oxfam to fight for the world's poorest people as government leaders thrashed out the next deal on climate change.

I've always been driven to do something in life that makes a difference. Since having my own children, I also want to protect the planet for them and for future generations.

I went to Bali because Oxfam's goal is to see an end to poverty and suffering in the world - and what, at the end of the day, is more important than that?

Climate change is all about the impact on humans, because if we don't deal with climate change, we won't be able to overcome poverty and suffering for future generations.

Swindon means a lot to me because I live here. We have already experienced flooding locally. I dread to think what could happen to people here if global warming continues and the predicted weather patterns happen - let's just say we'd be on the frontline in the battle against climate change.

Yet people in the poorest countries of the world, such as Bangladesh, in spite of not being responsible for the problem, are being hit first and worst by the impacts of climate change.

They are already on the frontline. For a flavour of what might happen here if we don't tackle climate change, we only need to look at the floods in Bangladesh and Orissa in India, where hundreds of thousands have been forced from their homes in the past few months.

After 11 of the warmest years on record during the past 12, and, according to the UN, 14 major climate disasters in 2007, it has become desperately urgent to get a global agreement on cutting down carbon emissions and helping poor countries to adapt.

So what happened in Bali? Thousands of government representatives gathered together from the start of December for two weeks of talks to agree an outline for the future of international action on climate change after 2012.

After late night wrangling and even tears in the conference chamber, an agreement was finally reached.

We campaigned in Bali for the richest, industrialised countries to recognise their responsibility for carbon emissions over the past 200 years and agree to help developing countries to adapt, as well as cutting carbon emissions now and in future.

We dressed up in polar bear suits (Charlie is pictured above with protesters) in the searing heat and held banners saying Humans Need Help Too - it certainly held the attention of the world's media!

The Bali conference made positive steps, with the 180 countries agreeing that deep cuts in greenhouse gases must be made. The rich countries agreed that poor countries must be given money to help them adapt to climate change. Developing countries will get help with new technologies to cut emissions and they may get money to protect forests from deforestation.

Yet we still have a long way to go as the leaders continue to negotiate for the next two years before they make a final agreement.

So we need to keep telling our politicians that we'll hold them to account on their promise to help poor countries adapt and to make deep cuts' in greenhouse gases. Of course we can all take personal action, but with the UK Climate bill up for discussion in Parliament next spring, political pressure will be critically important.

We must see definite targets agreed: industrialised countries must continue to take the lead in emission reductions, with cuts of at least 80 per cent by 2050. Scientists tell us that we need to keep global warming under 2C to avoid catastrophic climate change, but if greenhouse gases are allowed to rise at current rates we'll see a rise of at least 3C.

Bali will soon join the ranks of places that are milestones in history. The Bali roadmap' refers to an overall agreement that gives direction and shape to a two-year negotiating process on climate change, which ends in December 2009.

The success of this process must be the New Year Resolution that governments, industry and all of us should wish for in 2008."
