Climate Change and Suppression Tactics are Critical Factors Increasing Fires

The millions of people affected by 2020’s record-breaking and deadly fires can attest to the fact that wildfire hazards are increasing across western North America.

The millions of people affected by 2020’s record-breaking and deadly fires can attest to the fact that wildfire hazards are increasing across western North America.

Both climate change and forest management have been blamed, but the relative influence of these drivers is still heavily debated. The results of a recent study show that in some ecosystems, human-caused climate change is the predominant factor; in other places, the trend can also be attributed to a century of fire suppression that has produced dense, unhealthy forests.

Over the past decade, fire scientists have made major progress in understanding climate-fire relationships at large scales, such as across western North America. But a new paper published in the journal Environmental Research Letters details a study that takes this progress to the next level.
