Wildfires - California, USA

The catastrophic wildfires burning in California, which killed at least one person over the weekend and injured several others, are being fuelled by high temperatures, strong winds and years of withering drought influenced by climate change.

The Valley Fire ignited in drought-stricken Northern California early Saturday afternoon, destroying more than 400 homes and scorching 50,000 acres — an area more than twice the size of Manhattan — within about 12 hours.

The wildfires storming California have been four years in the making, as the drought, thought to be heavily influenced by climate change, has been starving California’s forests and mountains of water and snow, turning once-lush woods into crackling tinder that has ignited in explosive and unexpected ways.

The trend in wildfire destruction in California and throughout the West bends toward bigger, more destructive and drought-driven blazes. On average, wildfires burn six times the acreage they did 40 years ago, while the annual number of wildfires over 1,000 acres has doubled from 50 during an average year in the 1970s to more than 100 each year since 2002.

That scenario is playing out in California this week as just two of the state’s 13 most active and catastrophic wildfires — the Valley Fire and the Butte Fire — have burned more than 130,000 acres since Wednesday, leaving behind “mass destruction” and leading to numerous evacuations in the region.
