Researchers say places, including the Arctic, could be facing higher risk than other areas of the globe. The report says that nations need to recognize this risk and take steps in preparation. Many countries (including the U.S.) tend to prioritize reactive steps such as short-term firefighter response, as opposed to mitigation planning. A second report in the journal Nature last week found that nighttime fire intensity and flammable nighttime hours increased globally as well. Typically, fires weaken during the night due to lower temps and higher humidity, but warmer, drier air has contributed to an increase in nighttime fires. An example of this is in the Western U.S., which has seen a 28% increase in fire intensity during the night over the past 20 years.」4月7日 5時22分
