Knowra Climate change in Canada Climate change in Canada Long-term changes in Canada’s climate include rising temperatures, shifting precipitation, shrinking ice and snow, and resulting effects on ecosystems, infrastructure, and communities.
Arctic amplification : The Arctic warms faster than the global average, largely because feedbacks amplify temperature increases. This amplification makes northern Canada warm especially rapidly.
Greenhouse effect : The warming of Earth’s surface and lower atmosphere as gases absorb and re-emit infrared radiation. Human-enhanced greenhouse warming underlies Canada’s long-term temperature rise.
Climate change in the Canadian Arctic : Climate-driven changes in Canada’s Arctic, including rapid warming, ice loss, and permafrost thaw. Northern Canada experiences some of the country’s fastest and most visible changes.
Climate change mitigation : Human actions that reduce greenhouse gas emissions or increase their removal from the atmosphere. Mitigation limits the future warming that drives changes in Canada.
Detection and attribution of climate change : Methods for identifying climate changes and estimating the causes of observed trends and events. Attribution separates human influence from natural variability in Canadian changes.
Permafrost : Ground that remains at or below 0°C for at least two consecutive years. Thawing permafrost destabilizes northern buildings, roads, and landscapes.
Climate feedback : A process that amplifies or reduces an initial climate change. Snow and ice loss amplify warming by reducing the reflection of sunlight.
Climate change in British Columbia : Climate trends and impacts in British Columbia, including heat, drought, flooding, and wildfire risk. The province illustrates interacting mountain, coastal, forest, and urban climate hazards.
Climate change adaptation : Adjustments to human or natural systems that reduce harm from climate impacts or take advantage of opportunities. Adaptation addresses unavoidable effects on Canadian communities and ecosystems.
Climate model : A mathematical representation of the climate system used to simulate past and future climate. Models project regional Canadian conditions under different emissions pathways.
