April Melvin of EPA’s National Climate Change Division has spent some time in the field in Alaska. In a just-released publication her research team takes a look at how firefighting costs in Alaska are likely to change through the next several decades.
They use the ALFRESCO model developed at UAF, which simulates fire ignition and spread (annual timesteps) under different climate projections in 100-km grid cells. Read their paper (citation below) for all the details, but in a nutshell they found: 1) it’s hard to nail down precise fire cost records in the multi-jurisdictional setting! 2) Fire costs go up in the future and the biggest expenditures will be in the Full fire protection option. 3) by 2030, predicted federal fire suppression costs (not including base–support and pre-suppression) will average $27-47M annually under the RCP 4.5 (moderate emissions) climate projection. That compares to about $31M on average from 2002-2013. Adding in state costs boosts this to about $116M total firefighting cost for Alaska assuming the state costs are still roughly 68% of the total cost. Again this does not include base operating costs. The paper provides some good analysis for fire protection agencies to take to the bank. Or at least to the Legislature!
