Previous research, including from USA government scientists, has also concluded that climate change could have severe economic consequences, including damage to infrastructure, water supplies and agriculture. He also pointed out that it focused on the climate change consequences that would be borne by the USA - even though it is a global problem.
The report says more than 90 percent of the current warming is caused by humans.
