World powers accept warming limit

Developed and developing nations have agreed that global temperatures should not rise more than 2C above 1900 levels, a G8 summit declaration says.That is the level above which, the UN says, the Earth's climate system would become dangerously unstable.But the G8 failed to persuade developing countries to accept targets of cutting emissions by 50% by 2050.On Wednesday, the G8 agreed its own members would work towards 80% cuts by the same date.UN Secretary General Ban Ki-moon said the G8 had not done enough and should also set 2020 targets.Bridget Kendall reports.
