Gavin says :
the scenario closest to the observations is clearly Scenario B
So, I am trying to figure out – is Gavin spreading nonsense about CO2 growth, temperatures – or both?

How could this happen? We know now that increases in humidity and climate change are due to CO2.
“The world has been chilling sharply for about twenty years. If present trends continue, the world will be about four degrees colder for the global mean temperature in 1990, but eleven degrees colder in the year 2000. This is about twice what it would take to put us into an ice age.”
Kenneth Watt, Ecologist
By 2020, temperatures will be 4-6 degrees warmer than 1958

‘Frightening’ projection for Arctic melt
The Arctic Ocean could be free of ice in the summer as soon as 2010 or 2015 – something that hasn’t happened for more than a million years, according to a leading polar researcher.
QUEBEC — The Arctic Ocean could be free of ice in the summer as soon as 2010 or 2015 – something that hasn’t happened for more than a million years, according to a leading polar researcher.
Louis Fortier, scientific director of ArcticNet, a Canadian research network, said the sea ice is melting faster than predicted by models created by international teams of scientists, such as the Intergovernmental Panel on Climate Change (IPCC).
“you can argue that may be our projection of 2013 is already too conservative.”
In 1988, there was a lot of 5+ year old ice in the Arctic. Thick, old ice like that can’t melt during the summer, but it can disappear during the winter due to wind blowing it out into the warm waters of the North Atlantic.
That is exactly what happened, as most of the older ice was lost during the winters of 1988-1996.

The North Pole has become an island for the first time in human history as climate change has made it possible to circumnavigate the Arctic ice cap.
The historic development was revealed by satellite images taken last week showing that both the north-west and north-east passages have been opened by melting ice.
Prof Mark Serreze, a sea ice specialist at the National Snow and Ice Data Centre (NSIDC) in the US said the images suggested the Arctic may have entered a “death spiral” caused by global warming.
Shipping companies are already planning to exploit the first simultaneous opening of the routes since the beginning of the last Ice Age 125,000 years ago. The Beluga Group in Germany says it will send the first ship through the north-east passage, around Russia, next year, cutting 4,000 miles off the voyage from Germany to Japan.

“Examination of several proxy records (e.g., sediment cores) of sea ice indicate ice-free or near ice-free summer conditions for at least some time during the period of 15,000 to 5,000 years ago”
