Large reductions in carbon-dioxide emissions could have a modest effect in slowing climate change, delaying some of the effects by 50 to 100 years, according to a report by scientists at the Hadley Centre for Climate Protection and Research, part of the U.K. Meteorological Office. However, to achieve this delay, emissions cuts of 50 to 70 percent would be needed, while nations now are bickering over cuts in the 5 percent range that are called for in the Kyoto Protocol.
