The goal of this study was to determine the contribution of anthropogenic climate change to wildfire smoke PM2.5 mortality on a county-level across the continental United States from 2006 through 2020. Climate change contributed to approximately 15,000 wildfire particulate matter deaths over 15 years with interannual variability ranging from 130 (95% confidence interval: 64, 190) to 5100 (95% confidence interval: 2500, 7500) deaths and a cumulative economic burden of $160 billion. Approximately 34% of the additional deaths attributable to climate change occurred in 2020, costing $58 billion. The economic burden was highest in California, Oregon, and Washington. This highlights the substantial impacts on nature that result in human deaths from failure to reduce greenhouse gas emissions. In a scenario without climate change contributing to wildfire smoke PM2.5, tens of thousands of deaths could be avoided and billions of dollars saved every year.

The phase III study shows that giving prostate cancer patients fewer, higher doses of radiotherapy can be safe and effective in the long term.

Despite decades of public health messaging, Canadians are spending more time in the sun and using less sun protection – raising alarms among researchers as melanoma cases continue to climb.

That trend is highlighted in a McGill University-led study that analyzed national survey data collected between 2011 and 2018 from over 77,000 people, representing a weighted sample of 21 million Canadians.
