Climate Change

Climate change occurs when long-term weather patterns begin to shift. These periods of change have occurred throughout the Earth’s history over extended periods of time. However, since the Industrial Revolution the world has been warming at an unprecedented rate. Because of this, the current period of climate change is often referred to as “global warming.” Human activities that release heat-trapping greenhouse gases, such as the burning of fossil fuels, are largely responsible for this increased rate of change. The implications of this global increase in temperature are potentially disastrous and include extreme weather events, rising sea levels and loss of habitat for plants, animals and humans. In Canada, efforts to mitigate climate change include phasing-out coal-fired power plants in Ontario and instituting a carbon tax in British Columbia.

Invasive Species in Canada: Animals

Invasive species are any species that have, primarily with human help, become established in a new ecosystem. While it’s impossible to say exactly how many invasive species are living in Canada, in 2002 researchers estimated that at least 1,442 invasive species — including fish, plants, insects and invertebrates — now live in the country’s farmlands, forests and waterways. The complex environmental impacts of so many invasive species is unknown and, maybe, unknowable. Typically, non-natives are feared for their ability to reproduce much faster than native species and outcompete natives for food, habitat and other resources. Economically, invasive species are estimated to cost Canadians billions of dollars each year in lost revenue from natural resources and impacts on ecosystem services.

Muskeg

Muskeg (from Cree maskek and Ojibwe mashkiig, meaning “grassy bog”) is a type of northern landscape characterized by a wet environment, vegetation and peat deposits. Chiefly used in North America, the term muskeg escapes precise scientific definition. It encompasses various types of wetlands found in the boreal zone, including bogs, fens, swamps and mires. In Canada, muskeg and other peatlands cover up to 1.2 million km2, or 12 per cent of the country’s surface.

Coal in Canada

Coal is a fossil fuel that has been used as a source of energy in Canada since the 18th century. Canada is home to 0.6 per cent of the world’s coal resources. Most of the country’s coal reserves (over 95 per cent) are found in AlbertaBritish Columbia and Saskatchewan. In recent years, the environmental movement has opposed the coal industry for disrupting local ecosystems, creating adverse health effects and for its large contribution to the carbon-dioxide emissions that drive climate change. In an effort to curb harmful emissions, the federal government has signalled its intention to phase out traditional coal-fired electricity by 2030, and Alberta has a plan to achieve the same goal as a province.

Statistics

Statistics is the science concerned with the collection and analysis of numerical information to answer questions wisely. The term also refers to the numerical information that has been collected. Statistics has many applications in Canada, from government censuses and surveys, to decision making in industry, to medical research and technological innovation.

Andrew Weaver

Andrew John Weaver, OBC, FRSC, leader of the BC Green Party 2015–present, climate scientist (born 16 November 1961 in Victoria, BC). Andrew Weaver is a leading climate change researcher who has made historic gains for the Green Party of British Columbia in his second career as a politician. In 2013, he was elected the province’s first Green MLA. In 2017, he led the Greens to three seats. After the 2017 election, he engineered a power-sharing deal with the BC New Democratic Party and toppled the Liberal government of Christy Clark to help John Horgan become premier.

Solar Energy

The energy contained in sunlight is the source of life on Earth. Humans can harness it to generate power for our activities without producing harmful pollutants. There are many methods of converting solar energy into more readily usable forms of energy such as heat or electricity. The technologies we use to convert solar energy have a relatively small impact on the environment. However, they each have disadvantages that have kept them from being widely adopted.

In Canada, the use of solar energy to generate electricity and heat is growing quickly and is helping reduce pollution related to energy production. Despite Canada’s cold climate and high latitudes (which get less direct sunlight than mid-latitudes), solar power technologies are used in many places, from household rooftops to large power plants. The Canada Energy Regulator (formerly the National Energy Board) expects solar power to make up 3 per cent of Canada’s total electricity generation capacity by 2040.

National Parks of Canada

Canada’s national parks are protected areas established under federal legislation to preserve Canada’s natural heritage. They are administered by Parks Canada, a government agency that evolved from the world’s first national parks service, the Dominion Parks Branch, established in 1911. The National Parks System Plan, developed in 1970, divided Canada into 39 natural regions and set the goal of representing each region with at least one national park. Canada now has 48 national parks and national park reserves in 30 of these regions. In total, the parks cover more than 340,000 km2, which is over 3 per cent of Canada’s landmass. They protect important land and marine habitats, geographical features and sites of cultural significance. National parks also benefit local economies and the tourism industry in Canada.

Social History

Social history is a way of looking at how a society organizes itself and how this changes over time. The elements that make up Canada’s social history include climate and geography, as well as the transition to industrialization and urbanization.

Carbon Pricing in Canada

Carbon pricing plans impose a cost on the combustion of fossil fuels by industries and consumers — either directly through a tax, or indirectly through a cap-and-trade system. In a market economy like Canada’s, prices help regulate the supply and demand of goods and services. By influencing the price of a commodity like gasoline, through carbon pricing, governments aim to discourage its use and thereby reduce the greenhouse gas emissions that result from its consumption.

In 2016, Prime Minister Justin Trudeau announced a national climate-change policy that included a system of carbon pricing across Canada. As of June 2019, eight provinces and territories have carbon pricing plans that meet the requirements of the national policy. In the remaining provinces — Saskatchewan, Manitoba, Ontario and New Brunswick — Ottawa imposed or intends to impose its own carbon tax. The tax has vocal opponents on the political right, including some premiers and party leaders.
