He wrote an op-ed five years ago highlighting the dangers of the grass-fire cycle, when rains cause grass to grow, the rains stop, the grass dries out and then it burns. The problem isn't just in Hawaii, but across the U.S. Again, this isn't a new conversation. This study co-authored by Trauernicht eight years ago predicted increases in wildfire because of a growing population, rising temperatures and expanding invasive grass cover. Authors say grasslands and shrublands composed 24% of Hawaii's land cover at the time.
