محققان یک مرکز پژوهشی در نروژ بر اساس شبیه سازی های جدید دریافته اند که برخی تخمین ها در مورد میزان دی اکسید کربن موجود در جو کمتر از میزان واقعی بوده و این میزان 20 تا 25 درصد بیشتر از تخمین های فعلی است. این محققان در طی بررسی های خود متوجه شده اند که میزان طبیعت به میزان پیش بینی شده دی اکسید کربن جذب نمی کند. با این شرایط به نظر می رسد که نیاز به یک حرکت مصمم جهانی برای بهبود شرایط ضروری تر به نظر می رسد.

Unpleasant surprise from Norwegian climate researchers: he amount of CO2 in the atmosphere may be 20 to 25 percent higher than previously estimated by the UN. 

New research from two professors at the University of Bergen, Norway, reveals that nature absorbs much less greenhouse gas from the atmosphere than estimated by the Intergovernmental Panel on Climate Change (IPCC). The two professors, Eystein Jansen and Helge Drange of the Bjerknes Centre for Climate Research, have contributed to the IPCC.

The Bjerknes center has made the first simulations for the coming IPCC assessment report. The models show that the amount of CO₂ in the atmosphere could likely be 20 to 25 percent higher than previously estimated. Consequently climate change will happen faster, writes the Norwegian newspaper Dagsavisen.

The new computer models were presented to the Norwegian Minister for Environment, Erik Solheim earlier this week. In that connection Mr. Solheim stated that it is now even more important that the world achieves “a strong and clear pact” at the climate conference in Copenhagen later this year.

Erik Solheim also announced “stronger demands from Norway in the climate talks.”

Most likely, it will not be possible to reach the target, approved by leaders of the world's biggest economies, that temperature must not rise more than 2 degrees Celsius.

“The most realistic is no longer 2, but 3.5 or 4 degrees Celsius,” Helge Drange says to Norwegian weekly Teknisk Ukeblad.  “Then we will cross more thresholds with irreversible damage to water supply and food production”, says Drange.
