بررسی های اخیر توسط دانشمندان انگلیسی نشان داده است که هزینه سازگاری با تغییرات آب و هوا دو تا سه برابر بیشتر از پیش بینی های رسمی خواهد بود و این دانشمندان با توجه به این تخمین ها به مذاکره کنندگان هشدار داده اند. 

Climate Change Adaptation Expected To Cost 2–3 Times More Than Previously Estimated

ScienceDaily (Sep. 11, 2009) — UK scientists have warned that UN negotiations aimed at tackling climate change are based on substantial underestimates of what it will cost to adapt to its impacts.

The real costs of adaptation to climate change are likely to be two-to-three times greater than estimates made by the UN Framework Convention on Climate Change (UNFCCC), the researchers say.

In a study published by the International Institute for Environment and Development and the Grantham Institute for Climate Change, they add that costs will be even more when the full range of climate impacts on human activities is considered.

The UNFCCC has estimated annual global costs of adapting to climate change to be $40–170 billion, or the cost of about three Olympic Games per year.
