Climate Change Through Deep Time

The document outlines how Indigenous-led conservation, specifically through Guardian programs and Indigenous Protected and Conserved Areas (IPCAs), provides a scalable model for climate resilience and carbon sequestration in Canada. Using the Heiltsuk Nation's 14,000-year history of stewardship as a foundation, it advocates for a convergence of traditional knowledge and western science to manage ecosystems. The author highlights the critical role of the boreal forest in storing carbon and recommends that Crown governments provide long-term investment in Indigenous-led stewardship to achieve national conservation targets.

• The Heiltsuk Nation possesses a 14,000-year record of observing climate change and managing ecosystems, utilizing laws (ǧvi̓ḷás) based on respect and balance to survive the last Ice Age and subsequent environmental shifts.
• Indigenous Guardians programs, with over 70 operating in Canada, combine millennia of place-based expertise with western scientific tools to monitor climate impacts, such as shifts in migratory bird timing, river melt, and ocean acidification affecting Dungeness crabs.
• Indigenous Protected and Conserved Areas (IPCAs) are essential for Canada to meet international biodiversity and climate goals, as they generate sustainable prosperity and local employment.
• The Canadian boreal forest contains approximately 12 percent of the world's land-based carbon reserves; proposed IPCAs in this region could permanently protect over 20 billion tonnes of carbon, which is nearly equivalent to 100 years of Canada's annual industrial greenhouse gas emissions.
• The author recommends four priority areas for collective action: supporting Indigenous-led conservation to meet targets of protecting 25% of lands and waters by 2025 and 30% by 2030, promoting economic reconciliation, pioneering innovative financing, and recognizing nature-based solutions like carbon offsets in the boreal forest.
