Immediate cuts to emissions must be made
Cutting global emissions by three per cent a year is the only way to avoid a climate change tipping point, according to the UK Met Office.
The national meteorology organisation's Hadley Centre for climate change research has said the drastic cuts are the only way to stop a temperature rise of two degrees centigrade.
Vicky Pope, the Met Office's leading adviser on climate change to the government, warned of the need to start making emissions reductions immediately.
She said: "Even with large and early cuts in emissions, these projections indicate that temperatures are likely to rise to around 2C above pre-industrial levels by the end of the century. If action is delayed or is slow, then there is a significant risk of much larger increases in temperature."
In the best case scenario devised by the scientists, emissions drop until 2010, when they reach an annual rate of three per cent reductions per year. However, current rates show one per cent annual growth.
According to a recent study, in order to reach targets of reducing carbon emissions by 50 per cent by 2050, it would be necessary for half of all energy to come from renewable sources.http://www.metoffice.gov.uk/research/hadleycentre/index.h...
