Wildfire smoke does not carry a passport. A new article from Andrew Weaver at The Conversation, republished by Zoomer, explains why Donald Trump's claim that Canada is responsible for wildfire smoke affecting the U.S. is not supported by climate science. The piece details how human-caused climate change, driven by cumulative fossil carbon emissions, has made severe fire seasons more likely across North America and beyond. The article covers the role of lightning ignition, warmer temperatures, earlier snowmelt, and the limitations of forest management in remote boreal landscapes. It argues that adaptation measures like prescribed burning and FireSmart communities can reduce losses but cannot replace rapid decarbonization. The piece also discusses the need for geological net zero, durable carbon dioxide removal, and technologies like direct air capture paired with ocean thermal energy conversion. For readers focused on carbon markets and climate policy, the article provides a clear case for why mitigation, not just adaptation, is essential. It connects current wildfire events to the broader need for emissions reduction and carbon removal, making it a relevant read for anyone tracking the real-world consequences of delayed decarbonization.
