News release: “Scientists led by a former co-chair of the Intergovernmental Panel on Climate Change will warn today that the 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 are likely to be 2-3 times greater than estimates made by the UN Framework Convention on Climate Change (UNFCCC), say Professor Martin Parry and colleagues in a new report published by the International Institute for Environment and Development and the Grantham Institute for Climate Change at Imperial College London. The report adds that costs will be even more when the full range of climate impacts on human activities is considered.”
