Fact Checking the Wildfire-Climate Link
Critical Prescribed Burn
According to the C2ES website, the transformed successor of the PEW foundation’s Center on Global Climate Change, “Climate change has been a key factor in increasing the risk and extent of wildfires in the Western United States.” “Climate change enhances the drying of organic matter in forests and has doubled the number of large fires between 1984 and 2015 in the western United States.” NASA’s Global Climate Change webpage agrees stating, “hot and dry conditions in the atmosphere determine the likelihood of a fire starting, its intensity and the speed at which it spreads.
Thus every politician trying to excuse bad landscape policies, every environmental group and every scientist seeking funding, and every journalist promoting a crisis to attract readers repeatedly tells some version of the headline The Devastation of Human Life is in View: what a burning world tells is about climate change. The good news is scientific facts totally refute such fearful narratives.
A Candle Can Light Your Way
The average temperature of a candle’s flame is a whopping ~1800°F (~1000°C) and readily demonstrates how heat is transferred. Hold your hand to the side of the flame. Despite the flame’s high temperature, you can bring your hand very close to the candle because the wick’s small mass produces relatively small amounts of radiation. The closer you bring your hand to the flame, the more heat you can feel. That heat reaches your hand via heat wave radiation. Just inches away however you can’t sense much heat at all because radiation spreads out as the distance from the heat source increases, making the heat that reaches your hand increasingly less dense, and thus less intense. Although a bon fire may only reach temperatures of ~1110°F (~600°C), its larger mass produces more energy forcing you to stay much further away where the heat intensity becomes adequately reduced.
