A recent study suggests that human-caused climate change played a significant role in Canada's massive summer wildfires. The study found that climate change doubled the likelihood of the weather conditions that sparked the fires. Fire and climate scientists are weighing in on the issue, pointing to historical emissions of heat-trapping gases as a contributing factor.

They suggest that the United States should also consider its own role in climate change. Further details on the study and its findings are available from the source, including the specific regions in Canada that were affected by the wildfires and the group behind the study, World Weather Attribution.
