What are the health effects of wildfire smoke?
Wildfire smoke contains tiny particles called PM2.5, which can penetrate deep into the lungs and bloodstream. Exposure can cause respiratory problems, worsen asthma, and increase the risk of heart attacks. Vulnerable groups like children, the elderly, and those with pre-existing health conditions are at higher risk of serious health issues from wildfire smoke.

How is climate change making wildfires worse?
Climate change leads to hotter, drier conditions that create ideal environments for wildfires to start and spread. As global temperatures rise, wildfires become more frequent and intense, releasing more smoke and toxic particles into the air, which then affects air quality on a global scale.

What can communities do to protect themselves from wildfire smoke?
Communities can reduce exposure by staying indoors during smoky conditions, using air purifiers, and wearing masks if they need to go outside. Public health advisories and early warning systems are also vital in helping residents prepare and respond effectively to wildfire smoke events.

Are there policies in place to reduce wildfire risks in the future?
Many experts agree current policies are insufficient to address the rising threat of wildfires. Effective strategies include better land management, stricter regulations on emissions, and investment in firefighting resources. Global efforts to reduce greenhouse gas emissions are also critical in tackling the root causes of climate change and, consequently, wildfires.

How many deaths are linked to wildfire smoke now and in the future?
Recent studies project that wildfire smoke could cause up to 1.4 million deaths globally annually by 2100 if emissions are not curbed. In the US alone, deaths are expected to increase from 40,000 to over 70,000 annually by 2050, with California and New York most affected. These alarming figures highlight the urgent need for action to protect public health.
