Cost of climate change in Alaska
Researchers estimate that the potential economic damages to Alaska’s public infrastructure resulting from climate change may be around $4.2-5.5 billion for 2015-2099, depending on future climate change intensity; if proactive adaptation efforts are taken, estimated expenses are reduced to around $2.3-2.9 billion, the authors suggest.
