As Earth’s climate continues to change from heat-trapping gases spewed into the air, ever fewer people are out of reach from the billowing and deadly fingers of wildfire smoke, scientists say. (AP Photo/Tony Avelar, File)As smoky as the summer has been so far, scientists say it will likely be worse in future years because of climate change. They say as the world warms and weather gets more extreme, America will see nastier bouts of drought that lead to wildfires and then cause billowing and deadly smoke. The amount of land burned in the United States and Canada has more than tripled since the 1980s. One study estimates that globally more than 600,000 people per year die from wildfire smoke. Scientists warn against calling this a new normal because it's not going to stay this way. It's the new abnormal.
