I realise that Al Gore isn't particularly popular amongst Americans, but he seems to have won the respect of the rest of the world. Accused of lacking personality during the United States Presidential Election in 2000, this is a man who has shown himself to be an intelligent, articulate and good-humoured guy who is passionate about his message.

Climate change is a contentious issue given our limited understanding of Earth's temperature fluctuations and our even more limited weather records, dating back only a very short time in the grand scheme of things. It's easy to understand why people disagree on whether climate change has anything to do with man-made emissions or not, but one thing that should be easy to agree on is that reducing them can't in itself be a bad thing. All that's left to work out is the finer points of when, and by how much.
People don't act on good ideas alone. Prompting people into action requires the dedicated application of publicity in such a way as to personalise the issue for them. If you can make people understand how they're involved, and keep the issue current, there's some chance that you'll be able to overcome the boundless laziness of humanity and actually get people to do something positive.

Agree with him or not, Al Gore is doing his part to keep the message out there, phrased in an accessible way and delivered via accessible media. His political weight has helped garner him additional publicity for a campaign against climate change which has seen him win a Nobel Peace Prize which he shares with the UN Intergovernmental Panel on Climate Change.
In his acceptance speech he said that losing the 2000 election made him search for other opportunities to generate publicity for an issue which has always been important to him.
Seven years ago tomorrow, I read my own political obituary in a judgment that seemed to me harsh and mistaken — if not premature. But that unwelcome verdict also brought a precious if painful gift: an opportunity to search for fresh new ways to serve my purpose.
Unexpectedly, that quest has brought me here. Even though I fear my words cannot match this moment, I pray what I am feeling in my heart will be communicated clearly enough that those who hear me will say, "We must act."
He's clearly still mourning his lost opportunity in 2000, but he's not the only one. We've now had the chance to get to know both men on the world stage and I hope you'll forgive me for saying that if the roles were reversed, I don't think George W Bush would have ever won a Nobel Prize of any kind.

Comparing these two, its hard to see how Bush was elected once, let alone twice. I have no intention of forgiving America for that anytime soon. Five minutes of airtime is enough to see that Bush would earn his place at a war crimes trial, and that he would escape punishment on grounds of diminished capacity.
As Al Gore continues to attract praise and adulation, I too mourn his loss in 2000.
I'll leave you with another excerpt from his acceptance speech:
The great Norwegian playwright, Henrik Ibsen, wrote, "One of these days, the younger generation will come knocking at my door."
The future is knocking at our door right now. Make no mistake, the next generation will ask us one of two questions. Either they will ask: "What were you thinking; why didn't you act?" or they will ask instead: "How did you find the moral courage to rise and successfully resolve a crisis that so many said was impossible to solve?"
