Humanity’s biggest test

REVERSING change: Both R.K. Pachauri and Al Gore have been working to spread the message.
Fifteen years ago, Al Gore was derisively referred to by his political opponents as the “ozone man” of America, an unhinged oracle with a depressing message about the state of the earth. The announcement of the Nobel Prize for Peace 2007 jointly for Gore and the Intergovernmental Panel on Climate Change (IPCC) has come as a happy vindication for the man and the message.
If the IPCC scientists toiled to credibly calculate human influences that are changing the earth’s climate, Gore has carried the message to global audiences with patience, perseverance and a convincing scientific style. The best-known contribution to the campaign against global warming and climate change is his slideshow lecture-turned-documentary film, “An Inconvenient Truth”, which won Oscars for best documentary and best song.
The Nobel Peace Prize will now disseminate the message with even greater credibility. As the announcement said, “their efforts to build up and disseminate greater knowledge about man-made climate change, and to lay the foundations for the measures that are needed to counteract such change” have won IPCC and Al Gore the prize.
