Temperature and precipitation are fundamental climate quantities that directly affect human and natural systems. The emerging field of “event attribution” provides insights about how climate change may have affected the likelihood of events such as the 2013 flood in southern Alberta or the 2016 Fort McMurray wildfire. The climate crisis explained in 10 charts From the rise and rise of carbon dioxide in the atmosphere to possible solutions. On this page, we have current climate-based information for Winnipeg. ... in Ohio, far away from rising seas. While both human activities and natural variations in the climate have contributed to the observed warming in Canada, the human factor is dominant. Warming of the climate system during the Industrial Era is unequivocal, based on robust evidence from a suite of indicators. CSV XML EXCEL. Over the past three decades, the proportion of Canadian land and marine areas covered by snow and ice have decreased, and permafrost temperatures have risen (see Figure 5.1). CAADA’S CHAGIG CLIMATE REPORT 116 Chapter Key Findings 4.2: Temperature It is virtually certain that Canada’s climate has warmed and that it will warm further in the future. View Chapter. No consistent pattern of nutrient change has been observed for the Northwest Atlantic Ocean off Canada. Extreme high water-level events are expected to become larger and occur more often in areas where, and in seasons when, there is increased open water along Canada’s Arctic and Atlantic coasts, as a result of declining sea ice cover, leading to increased wave action and larger storm surges (high confidence). This measure has risen an estimated 0.85°C (90% uncertainty range between 0.65°C and 1.06°C) over the period 1880–2012. According to New Zealand's National Climate Centre, several stations had record or near-record warm mean, maximum, and minimum temperatures. Most Canadian Arctic marine regions could be sea ice–free for at least one month in the summer by 2050, but sea ice will continue to be found along the northern coast of the CAA. As you might expect, a passenger-kilometre is equal to moving one person one kilometre. This chapter provides an overview of Earth system models and how they are used to simulate historical climate and to make projections of future climate. Climate data web site is a gateway to information on matters such as past weather, climate normals, historical radar, almanac averages and extremes, and engineering climate data. Editor’s pick: best of 2019. Sixty-year records of landfast sea ice thickness show evidence of thinning ice in the CAA. Significant reductions in sea ice area over the period 1968–2016 were evident in the summer and fall across the Canadian Arctic (5% to 20% per decade, depending on region), and in winter and spring in eastern Canadian waters (5% to 10% per decade). Global temperature change is effectively irreversible on multi-century timescales. However, increases in salinity are expected in off-shelf waters south of Atlantic Canada due to the northward shift of subtropical water (medium confidence). Disturbances of the water cycle by humans (dams, diversions, and withdrawals) make it difficult to discern climate-related changes. The Climate Atlas. There has been a slight long-term freshening of upper-ocean waters in most areas off Canada as a result of various factors related to anthropogenic climate change, in addition to natural decadal-scale variability (medium confidence). Download historical data for 20 million indicators using your browser. Canada’s climate varies wildly based on geography, from perma-frost in the north to four distinct seasons towards the equator. Due to land subsidence, parts of Atlantic Canada are projected to experience relative sea-level change higher than the global average during the coming century (high confidence). The ability of greenhouse gases (GHGs) in Earth’s atmosphere to absorb heat energy radiated from the Earth is well understood. Relative sea level has increased in most regions of Canada over the last century and even exceeded the global rate of change in southern Atlantic Canada, where land is subsiding. In the near term (to approximately 2040), projected warming will be similar under all emission pathways. Stories and explanations about climate change, and local climate data that can be explored using maps and graphs. In both cases, human-caused greenhouse gas emissions may have increased the risk of such extreme events relative to their risk in a pre-industrial climate. Warming will lead to a loss of permafrost and alteration of the landscape as thawing occurs. Paid in as of Dec 31, 2013. A similar majority believe it will have a … It is extremely likely that human activities, especially emissions of greenhouse gases, are the main cause of observed warming since the mid-20th century. Owing to uncertainty regarding future human activity (in particular, the extent to which ambitious emission reductions will be implemented), a range of future scenarios must be used. Ocean chemistry has undergone changes, such as increasing acidity and decreasing subsurface oxygen concentrations, as a result of anthropogenic climate change. Oceans surrounding Canada are projected to continue to warm over the 21st century in response to past and future emissions of greenhouse gases. This rise in atmospheric GHG levels, predominantly carbon dioxide, has been the main driver of climate warming during the Industrial Era. It is expected that projected changes to temperature and precipitation will influence future groundwater levels; however, the magnitude and even direction of change is not clear. This trend is expected to continue, with acidification occurring most rapidly in the Arctic Ocean (high confidence). What this graph shows is that there are a lot of different things that contribute to climate change — not just burning fossil fuels. Finances ... Graph, map and compare more than 1,000 time series indicators from the World Development Indicators. Freshwater resources are also linked to the ocean via runoff in coastal areas. The projected amount of global sea-level rise in the 21st century is many tens of centimetres and it may exceed one metre. Globally, sea level has risen, and is projected to continue to rise. However, the magnitude of these decreases will depend on how much future precipitation increases offset increased evaporation. Natural factors cannot explain this observed warming. The following tables show the average maximum and minimum temperatures of Canada of various cities across Canada, based on the climate period from 1981-2010 for the months of January and July (generally the lowest and highest average temperature months, but not in every case).. This is compounded by increases in ocean wave heights in areas that have experienced seasonal reductions in sea ice. Volcanic eruptions have cooling effects on global climate that can last several years but cannot explain the observed long-term change in global temperature. As temperatures increase, there will continue to be a shift from snow to rain in the spring and fall seasons. Finances ... Graph, map and compare more than 1,000 time series indicators from the World Development Indicators. 1:09 Prime Minister Trudeau addresses climate change in Canada… • The 2016 national emissions were revised up by 4 MtCO2 -- from 704 MtCO2 to 708 MtCO2. Extreme temperature changes, both in observations and future projections, are consistent with warming. Over the same time period, seasonal maximum snow water equivalent (SWEmax), which is indicative of seasonally accumulated snow available for spring melt, decreased across the Maritimes, southern Ontario, and nearly all of Canadian land areas north of 55° north latitude, while it increased across southern Saskatchewan and parts of Alberta and British Columbia. Projected warming and thawing permafrost has the potential to cause future changes, including rapid drainage, in many northern Canadian lakes (medium confidence). Sea-level rise along some Canadian coastlines will be higher than the global average during this century, leading to increased flooding and erosion. The Trading Economics Application Programming Interface (API) provides direct access to our data. The climate crisis explained in 10 charts From the rise and rise of carbon dioxide in the atmosphere to possible solutions. Regional observations identify warming rates of about 0.1°C per decade in the central Mackenzie Valley and 0.3°C to 0.5°C per decade in the high Arctic. This includes evidence from observations, from improved understanding of processes and feedbacks within the system that determine how the climate system responds to both natural and human-induced perturbations, and from climate models (see Chapter 3.3.1). Each of the last three full decades (1980s, 1990s, and 2000s) has broken successive records for average 10-year temperatures. This climate is considered to be Csb according to the Köppen-Geiger climate classification. On average, the models project a future global mean temperature change (relative to the 1986–2005 reference period) of about 1°C for the low emission scenario (Representative Concentration Pathway [RCP] 2.6) and 3.7°C for the high emission scenario (RCP 8.5) by the late 21st century, with individual model results ranging about 1°C above or below the multi-model average. This will result in increased flooding, which is expected to lead to infrastructure and ecosystem damage as well as coastline erosion, putting communities at risk. The winter months are much rainier than the summer months in Vancouver. This is because the total amount of carbon dioxide emitted over time is the main determinant of global temperature change and because carbon dioxide has a long (century-scale) lifetime in the atmosphere. Most small ice caps and ice shelves in the Canadian Arctic will disappear by 2100 (very high confidence). It is also anticipated that water-related extremes, such as droughts and floods, will intensify these impacts. The duration of seasonal lake ice cover has declined across Canada over the past five decades due to later ice formation in fall and earlier spring breakup (high confidence). But this continues a pattern of high-temperature records in the UK over the last few decades, as a result of our warming climate.” Winter The Climate Atlas of Canada is an interactive tool for citizens, researchers, businesses, and community and political leaders to learn about climate change in Canada. Snow cover fraction decreased between 5% and 10% per decade since 1981 due to later snow onset and earlier spring melt. Lake ice cover is changing across Canada, driven primarily by earlier spring breakup. Topography. The physical and chemical trends observed in the oceans surrounding Canada are consistent with changes observed in the atmosphere, cryosphere, freshwater systems, and adjoining oceans. 1768-2015 Data | 2019-2020 Forecast | Historical | Chart. However, there is an area south of Greenland where there has been little ocean warming, so regional trends do differ. However, there are regions of Canada (e.g., Hudson Bay) where relative sea level has fallen as a result of the rate of uplift being higher than the rate of global sea-level rise. The most serious impacts of climate change are often related to changes in climate extremes. Seasonal maximum lake ice cover for the Great Lakes is highly variable since 1971 (very high confidence), with no significant trend. Further changes to the cryosphere over the coming decades are virtually certain, as temperatures are projected to increase under all future emission scenarios. Low subsurface oxygen conditions will become more widespread and detrimental to marine life in future, as a result of continuing climate change (medium confidence). In addition, future changes are determined from a multitude of hydrological models, using output from numerous climate models with different emission scenarios. Annual and winter precipitation is projected to increase everywhere in Canada over the 21st century, with larger percentage changes in northern Canada. Developed by experts from 14 research organisations and NGOs from the majority of the G20 countries, the report covers 80 indicators. Explore Chapters Download Full Report (PDF, 34MB) Headline Statements Headline Statements. Regional and seasonal variability in the SCF trends reflects internal climate variability in surface temperature trends. Last week shown: week 44 in 2020. Of particular concern are impacts in regions that currently rely on snow and ice melt as freshwater sources, as well as continental interior areas, where increased evapotranspiration from warmer temperatures could reduce future water supplies. Recent USA-Canada snow cover . In Vancouver, the average annual temperature is 9.9 °C | 49.8 °F. Average Daily Maximum – Minimum – Sunshine – Raindays – Snowdays – Snowdepth – Windspeed. Temperatures have increased more in northern Canada than in southern Canada, and more in winter than in summer. Canada's changing climate report Vegan Society of Canada News April 4th 2019. The Climate Change Knowledge Portal is a hub of information, data and reports about climate change around the world. Multi-year ice will, therefore, still drift into the Northwest Passage (and present a navigation hazard for shipping) even when the Arctic Ocean is sea ice-free during the summer. Annual and seasonal mean temperatures across Canada have increased, with the greatest warming occurring in winter. It is virtually certain that Canada’s climate has warmed and that it will warm further in the future. The portion of the year with snow cover decreased across most of Canada (very high confidence1) as did the seasonal snow accumulation (medium confidence). The relationship between cumulative emissions of carbon dioxide (CO2) and global mean surface temperature provides a simple means of connecting emissions from fossil fuels — the main source of anthropogenic CO2 — to climate change. Advanced tools for academia, climate scenario developers, and other expert users. 2.3.3 Urban Green Space . Across inaccessible areas that have few measurements, scientists use surrounding temperatures and other information to estimate the missing values. The Intergovernmental Panel on Climate Change (IPCC, 201424) has assessed that, to have a 50% chance of keeping global warming to less than 2°C above the pre-industrial value, CO2 emissions from 2011 onward would have to remain below 1300 billion tonnes of CO2 (GtCO2), roughly equal to what has already been emitted since the beginning of the Industrial Era. Climate of Vancouver, British Columbia Unusually for a Canadian city, Vancouver has relatively mild winters with little snow. Ice cap volume data from David Burgess, Natural Resources Canada; ground temperature data from Sharon Smith, Natural Resources Canada; lake ice thickness data from Claude Duguay, University of Waterloo; Arctic river discharge data from Stephen Dery, University of Northern British Columbia. Climate projections are based on computer models that represent the global climate system at coarse resolution. Canada Climate. We are currently producing 3 kinds of charts: daily temperatures […] Canada is warming up twice as fast as the rest of the world and that warming is “effectively irreversible,” a recent scientific report from Environment and Climate Change Canada noted. But by the late 21st century, the differences between possible emission pathways will have a considerable effect. Perennial sea ice in the Canadian Arctic is being replaced by thinner seasonal sea ice: multi-year ice losses are greatest in the Beaufort Sea and the Canadian Arctic Archipelago (CAA), approaching 10% per decade. Here are some average weather facts we collected from our historical climate data: Churchill has dry periods in January, February, March and December. While modest, these increases are important because permafrost temperatures in these regions are currently close to zero, so the ground is vulnerable to thawing. However it does rain a lot during winter. Widespread formation of thermokarst landforms have been observed across northern Canada. The Climate Atlas of Canada shows users what trends to expect in their communities as a result of climate change Adapted from the interactive Climate Atlas of Canada, this map shows the projected number of days with temperatures of 25 degrees Celsius or higher per year by the end of this century if global warming continues unchecked, with dark red representing 100+ days. Data provided by Hope Not Hate, in a survey conducted by Focaldata between Aug. 30 and Sept. 9, 2019, including Brazil, Canada, France, Germany, Italy, Poland, the United Kingdom and the United States. While, in general, precipitation is projected to increase in the future, summer precipitation in parts of southern Canada is projected to decrease by the late 21st century under a high emission scenario. It is very likely that snow cover duration will decline to mid-century across Canada due to increases in surface air temperature under all emissions scenarios. However, uncertainty in climate projections is larger as one goes from global to regional to local scale. The impacts are expected to be more prominent toward the end of this century under higher emission scenarios, given the larger associated climate changes. Published on August 23, 2019. The most notable warm June 2019 temperature departures from average were observed across central and eastern Europe, northern Russia, northeastern Canada, and southern parts of South America, where temperatures were 2.0°C (3.6°F) above the 1981–2010 average or higher. Canada’s climate pledges. Nutrient supply to the ocean-surface layer has generally decreased in the North Pacific Ocean, consistent with increasing upper-ocean stratification (medium confidence). Freshwater availability in Canada is influenced by a multitude of factors: some natural, some as a result of human activity. Salinity has increased below the surface in some mid-latitude areas, indicating a northward shift of saltier subtropical water (medium confidence).
