This year is set to be one of the warmest on record in Scotland, environmental campaigners say.
This year's spring was the second warmest on record
WWF Scotland has analysed Met Office figures and concluded that the last month in particular had been exceptionally warm, dull and wet.
June was warmer and wetter than average and the spring season in Scotland was the second-warmest ever.
The summer of 2006 was unusually warm, and thanks to an exceptional autumn, the year as a whole broke all records.
WWF Scotland's director, Dr Richard Dixon, said the Scottish government's Climate Change Bill should be welcomed.
But he said the target of reducing greenhouse gases by 80% before 2050 did not remove the need to take action now.
"While the proposed target is very welcome, we need action now, even before the bill is written to make sure we don't lose momentum in addressing our contribution to climate change," he said.
"Scotland escaped the major flooding which hit the north of England but it was still a very wet June here.
"Yet again people felt it was cool but the temperatures were actually still nearly a degree above the long-term averages, with 2007 still on course to be one of the warmest years on record."
The Scottish Green Party agreed that action to combat climate change should not wait until the new legislation comes into place, which may not happen until 2009.
MSPs said Scotland should be aiming to reduce pollution every year and cast doubt on a number of transport projects being pursued by government which they said would only contribute to the climate change problem.
Green MSP Patrick Harvie, convener of the Scottish Parliament's transport, infrastructure and climate change committee, said: "Legislation is important, and we look forward to it obliging Scottish government to put in place actions to reduce pollution every year, but we must start this year.
"That means there are major question marks over projects that will increase carbon emissions such as the Aberdeen Bypass, the M74 Extension and the expansion of airports.
"And it means that stalled projects that would tackle congestion and reduce traffic levels such as the Aberdeen and Glasgow Crossrail schemes need to be dusted off and looked at again."
