2C climate target may need to change: UK scientist | Reuters

(Reuters) - A widely agreed international target to avoid dangerous global warming must take account of local impacts and may need to change, said the chief scientist at the MetOffice Hadley Center, Britain's biggest climate research center.

Julia Slingo said the target of limiting global temperature rise to 2 degrees Celsius (2C) may need adjusting to take into account research into local and regional effects, particularly on rainfall patterns, as climate science advances.

Slingo added: "Temperature change in many respects is not the most dangerous part of climate change. The most dangerous part is arguably around the shift of regional rainfall patterns.

"The greater understanding we have now ... is that a fraction of the carbon we put in the atmosphere will stay there forever, all else being equal.

"There's an irreversible nature to temperature, carbon dioxide and sea level rise which goes on for several centuries. That has to enter into our consideration of what's dangerous."
