Canada’s Top Climate Change Risks identifies the top risk areas based on the extent and likelihood of the potential damage, and rates the risk areas according to society’s ability to adapt and reduce negative outcomes. These 12 major areas of risk are: agriculture and food, coastal communities, ecosystems, fisheries, forestry, geopolitical dynamics, governance and capacity, human health and wellness, Indigenous ways of life, northern communities, physical infrastructure, and water. The report describes an approach to inform federal risk prioritization and adaptation responses. The Panel outlines a multi-layered method of prioritizing adaptation measures based on an understanding of the risk, adaptation potential, and federal roles and responsibilities.

This report begins with an overview of climate change and Canada's commitments under the Framework Convention on Climate Change, then reviews national characteristics affecting greenhouse gas emissions, the national greenhouse gas inventory, and policies & measures under the National Action Program on Climate Change. This is followed by chapters covering: a national projection of greenhouse gas emissions to 2020; possible impacts of climate change on Canada, including implications for water resources, health, agriculture, and forestry, as well as Canadian initiatives regarding adaptation to climate change; financial assistance & technology transfer activities related to climate change, including international initiatives; research & monitoring activities related to climate change; and education, training, & public awareness initiatives. Appendices include summaries of federal & provincial/territorial policies & measures affecting greenhouse gas emissions, by sector.

Discusses current and future risks and opportunities that climate change presents to Canada, with a focus on human and managed systems. Based on analysis of existing knowledge.

In fall 2015, the newly elected Trudeau government endorsed the Paris Agreement and promised to tackle global warming. In 2016, it released a major report which set out a national energy strategy embracing clean growth, technological innovation and carbon pricing. Rather than putting in place tough measures to achieve the Paris targets, however, the government reframed global warming as a market opportunity for Canada's clean technology sector. The Big Stall traces the origins of the government's climate change plan back to the energy sector itself — in particular Big Oil. It shows how, in the last fifteen years, Big Oil has infiltrated provincial and federal governments, academia, media and the non-profit sector to sway government and public opinion on the realities of climate change and what needs to be done about it. Working both behind the scenes and in high-profile networks, Canada's energy companies moved the debate away from discussion of the measures required to create a zero-carbon world and towards market-based solutions that will cut carbon dioxide emissions — but not enough to prevent severe climate impacts. This is how Big Oil and think tanks unraveled the Kyoto Protocol, and how Rachel Notley came to deliver the Business Council of Canada's energy plan. Donald Gutstein explains how and why the door has been left wide open for oil companies to determine their own futures in Canada, and to go on drilling new wells, building new oil sands plants and constructing new pipelines. This book offers the background information readers need to challenge politicians claiming they are taking meaningful action on global warming.

The impacts of changing climate are already evident in Canada and globally. Scientific understanding of climate change indicates that Canada will experience significant shifts in weather patterns over the period of a single generation, a trend that will likely continue for several centuries. Communities of all sizes will face many new risks and opportunities. Managing the impacts of a changing climate will require developing local strategies.

As climate has warmed over recent years, a new pattern of more frequent and more intense weather events has unfolded across the globe. Climate models simulate such changes in extreme events, and some of the reasons for the changes are well understood. Warming increases the likelihood of extremely hot days and nights, favors increased atmospheric moisture that may result in more frequent heavy rainfall and snowfall, and leads to evaporation that can exacerbate droughts. Even with evidence of these broad trends, scientists cautioned in the past that individual weather events couldn't be attributed to climate change. Now, with advances in understanding the climate science behind extreme events and the science of extreme event attribution, such blanket statements may not be accurate. The relatively young science of extreme event attribution seeks to tease out the influence of human-cause climate change from other factors, such as natural sources of variability like El Niño, as contributors to individual extreme events. Event attribution can answer questions about how much climate change influenced the probability or intensity of a specific type of weather event. As event attribution capabilities improve, they could help inform choices about assessing and managing risk, and in guiding climate adaptation strategies. This report examines the current state of science of extreme weather attribution, and identifies ways to move the science forward to improve attribution capabilities.
