Do you remember the Al Gore film about climate change? I do remember the boom that cause this film, but I also keep in mind that this climate change has been an issue for many many years, since the first media news a decade ago started talking about the hole in the Ozone layer.

Today's news says that the former US vice-president Al Gore and the UN climate change panel will share the 2007 Nobel peace prize for raising awareness of the risks of climate change, the Nobel committee announced.

Mr Gore is probably the single individual who has done most to create greater worldwide understanding of the measures that need to be adopted," the committee said. He has consistently said he is not interested in running again for the White House, insisting he can be more effective in the fight against climate change outside mainstream politics.

The other presidential candidates - Hillary Clinton, in particular - have so far disappointed environmental activists by shying away from promising aggressive action to deal with America's contribution to climate change.
