After years of delays, the Kyoto Protocol aimed at combating global warming due to anthropogenic greenhouse gases finally came into effect on February 16, eight years after it was first signed in 1997. However, it may be too little too late according to some scientists. Researchers at the Scripps Institution of Oceanography in La Jolla, California produced new evidence this week that ocean warming is strongly linked to human activity over the past four decades years. This, they say, puts paid to the doubters. However, eight years of wrangling between nations over the ratification of the Kyoto Protocol resulted in US opting out in 2001 and the big developing nations, Brazil, China and India, being left out of the equation.
Kyoto at long last, but too late?
