President Donald Trump has blamed improper forest management for Canadian wildfires whose smoke drifted into the Midwestern and Northeastern U.S. earlier this month. “Preventing and reducing the risk of wildland fire is a key component of climate change adaptation,” one page said. “But climate change is lengthening fire seasons, and increasing temperatures, causing fuels to dry out more intensely than in the past. Climate change is also increasing lightning strikes, the main ignition source for these wildfires. The windows where conditions to do prescribed burns are safe are “rapidly narrowing” due to climate change, Phillips said.
