Climate Changes Outpacing Worst-case Projections

Global temperatures may be 4 degrees Celsius hotter by the mid-2050s if current greenhouse gas emissions trends continue, said a study published on Monday.

The study, by Britain's Met Office Hadley Center, echoed a U.N. report last week which found that climate changes were outpacing worst-case scenarios forecast in 2007 by the U.N.'s Intergovernmental Panel on Climate Change (IPCC).

"Our results are showing similar patterns (to the IPCC) but also show the possibility that more extreme changes can happen," said Debbie Hemming, co-author of the research published at the start of a climate change conference at Oxford University.

Leaders of the main greenhouse gas-emitting countries recognized in July a scientific view that temperatures should not exceed 2 degrees above pre-industrial levels, to avoid more dangerous changes to the world's climate.

The IPCC shared the 2007 Nobel Peace Prize for its fourth assessment report, or AR4. One finding was that global temperatures could rise by 4 degrees by the end of the 2050s. Monday's study confirmed that warming could happen even earlier, by the mid-2050s, and suggested more extreme local effects.
