Global temperatures were almost 0.5 degrees Celsius above average in the first third of 2007, weather experts said Tuesday ahead of a G8 summit focused on climate change.
The world now has a 60 percent chance of experiencing its warmest year on record in 2007, said Britain's Met Office on the eve of the Group of Eight summit in Germany starting Wednesday.
The figures also revealed that this spring in Britain has been the warmest since records began in 1914, with the average temperature at 9.0 degrees Celsius, beating the previous record of 8.8 degrees Celsius set in 1945.
Globally, the British weather centre said that 2007 could set a record, but much depends on events around the world. "These latest...figures show that the first four months of 2007 are on track with our global forecast for a warmer than average year," said Met Office climate expert David Parker.
