Scientists examine causes for lull in warming

The Economist says Climate scientists must do more to work out how exceptionally cold winters or a dip in world temperatures fit their theories of global warming, if they are to persuade an increasingly sceptical public.

At stake is public belief that greenhouse gas emissions are warming the planet, and political momentum to act as governments struggle to agree a climate treaty which could direct trillions of dollars into renewable energy, away from fossil fuels.
Jeff Knight of the Hadley Centre says of the lull in temperatures since 1998 :
"Solar might be one part of it," said the Hadley's Jeff Knight, adding that changes in the way data was gathered could be a factor, as well as shifts in the heat stored by oceans.

The sun goes through phases in activity, and since 2001 has been in a downturn meaning it may have heated the earth a little less, scientists say.
"We've not put our finger precisely on what has changed," Knight said. "(But) If you add all these things together ... there's nothing really there to challenge the idea that there's going to be large warming in the 21st century
"We've not put our finger precisely on what has changed " Wow ! This is Settled Science .   
 We don't know what is going on but it is definitely going to be large warming in the 21st Century!
They think the public will believe anything - they obviously have not read the latest polls.
