Marine ice sheet instability processes in Antarctica may add substantially to these values, including the possibility of a 2-meter sea level rise by 2100 under high emissions. Climate change has led to decades of shrinking and thinning of the Arctic sea ice . While ice-free summers are expected to be rare at 1.5 °C degrees of warming, they are set to occur once every three to ten years at

The tornado also ripped up trees, flipped cars, and left thousands of people without power. No one was killed. Situated in hilly terrain of the Humber River Valley , historic Woodbridge rests at an average elevation of 200 metres between Highway 27 and Pine Valley Drive. The terrain can be described as
1800-519: A warming level of 2 °C. Higher atmospheric CO 2 concentrations cause more CO 2 to dissolve in the oceans, which is making them more acidic . Because oxygen is less soluble in warmer water, its concentrations in the ocean are decreasing , and dead zones are expanding. Greater degrees of global warming increase the risk of passing through ' tipping points '—thresholds beyond which certain major impacts can no longer be avoided even if temperatures return to their previous state. For instance,

Oceanic CO 2 uptake is slow enough that ocean acidification will also continue for hundreds to thousands of years. Deep oceans (below 2,000 metres (6,600 ft)) are also already committed to losing over 10% of their dissolved oxygen by the warming which occurred to date. Further, the West Antarctic ice sheet appears committed to practically irreversible melting, which would increase

As of the 2021 census, the top three ethnic groups in Woodbridge are Italian (49,660; 46.7%; which, until
2400-711: Is determined by modelling the carbon cycle and climate sensitivity to greenhouse gases. According to UNEP , global warming can be kept below 1.5 °C with a 50% chance if emissions after 2023 do not exceed 200 gigatonnes of CO 2 . This corresponds to around 4 years of current emissions. To stay under 2.0 °C, the carbon budget is 900 gigatonnes of CO 2 , or 16 years of current emissions. The climate system experiences various cycles on its own which can last for years, decades or even centuries. For example, El Niño events cause short-term spikes in surface temperature while La Niña events cause short term cooling. Their relative frequency can affect global temperature trends on

Smaller contributions come from black carbon (from combustion of fossil fuels and biomass), and from dust. Globally, aerosols have been declining since 1990 due to pollution controls, meaning that they no longer mask greenhouse gas warming as much. Aerosols also have indirect effects on

The main reinforcing feedbacks are the water-vapour feedback , the ice–albedo feedback , and the net effect of clouds. The primary balancing mechanism is radiative cooling , as Earth's surface gives off more heat to space in response to rising temperature. In addition to temperature feedbacks, there are feedbacks in

The long-term effects of climate change on oceans include further ice melt, ocean warming , sea level rise, ocean acidification and ocean deoxygenation. The timescale of long-term impacts are centuries to millennia due to CO 2 's long atmospheric lifetime. The result
3500-657: The Earth's energy budget . Sulfate aerosols act as cloud condensation nuclei and lead to clouds that have more and smaller cloud droplets. These clouds reflect solar radiation more efficiently than clouds with fewer and larger droplets. They also reduce the growth of raindrops , which makes clouds more reflective to incoming sunlight. Indirect effects of aerosols are the largest uncertainty in radiative forcing . While aerosols typically limit global warming by reflecting sunlight, black carbon in soot that falls on snow or ice can contribute to global warming. Not only does this increase
3600-568: The Greenland ice sheet is already melting, but if global warming reaches levels between 1.7 °C and 2.3 °C, its melting will continue until it fully disappears. If the warming is later reduced to 1.5 °C or less, it will still lose a lot more ice than if the warming was never allowed to reach the threshold in the first place. While the ice sheets would melt over millennia, other tipping points would occur faster and give societies less time to respond. The collapse of major ocean currents like
3700-835: The Greenland ice sheet . Under the 2015 Paris Agreement , nations collectively agreed to keep warming "well under 2 °C". However, with pledges made under the Agreement, global warming would still reach about 2.8 °C (5.0 °F) by the end of the century. Limiting warming to 1.5 °C would require halving emissions by 2030 and achieving net-zero emissions by 2050. Fossil fuel use can be phased out by conserving energy and switching to energy sources that do not produce significant carbon pollution. These energy sources include wind , solar , hydro , and nuclear power . Cleanly generated electricity can replace fossil fuels for powering transportation , heating buildings , and running industrial processes. Carbon can also be removed from

The upper atmosphere (the stratosphere ) would also be warming if the Sun
4300-971: The extinction of many species. The oceans have heated more slowly than the land, but plants and animals in the ocean have migrated towards the colder poles faster than species on land. Just as on land, heat waves in the ocean occur more frequently due to climate change, harming a wide range of organisms such as corals, kelp , and seabirds . Ocean acidification makes it harder for marine calcifying organisms such as mussels , barnacles and corals to produce shells and skeletons ; and heatwaves have bleached coral reefs . Harmful algal blooms enhanced by climate change and eutrophication lower oxygen levels, disrupt food webs and cause great loss of marine life. Coastal ecosystems are under particular stress. Almost half of global wetlands have disappeared due to climate change and other human impacts. Plants have come under increased stress from damage by insects.

4600-405: The 18th century and 1970 there was little net warming, as the warming impact of greenhouse gas emissions was offset by cooling from sulfur dioxide emissions. Sulfur dioxide causes acid rain , but it also produces sulfate aerosols in the atmosphere, which reflect sunlight and cause global dimming . After 1970, the increasing accumulation of greenhouse gases and controls on sulfur pollution led to

Scientifically, global warming refers only to increased surface warming, while climate change describes both global warming and its effects on Earth's climate system , such as precipitation changes. Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. Global warming —used as early as 1975 —became

This is because climate change increases droughts and heat waves that eventually inhibit plant growth on land, and soils will release more carbon from dead plants when they are warmer . The rate at which oceans absorb atmospheric carbon will be lowered as they become more acidic and experience changes in thermohaline circulation and phytoplankton distribution. Uncertainty over feedbacks, particularly cloud cover,

The World Meteorological Organization estimates there is an 80% chance that global temperatures will exceed 1.5 °C warming for at least one year between 2024 and 2028. The chance of the 5-year average being above 1.5 °C is almost half. The IPCC expects the 20-year average global temperature to exceed +1.5 °C in
6700-444: The dominant direct influence on temperature from land use change. Thus, land use change to date is estimated to have a slight cooling effect. Air pollution, in the form of aerosols, affects the climate on a large scale. Aerosols scatter and absorb solar radiation. From 1961 to 1990, a gradual reduction in the amount of sunlight reaching the Earth's surface was observed. This phenomenon is popularly known as global dimming , and
6800-610: The early 2030s. The IPCC Sixth Assessment Report (2021) included projections that by 2100 global warming is very likely to reach 1.0–1.8 °C under a scenario with very low emissions of greenhouse gases , 2.1–3.5 °C under an intermediate emissions scenario , or 3.3–5.7 °C under a very high emissions scenario . The warming will continue past 2100 in the intermediate and high emission scenarios, with future projections of global surface temperatures by year 2300 being similar to millions of years ago. The remaining carbon budget for staying beneath certain temperature increases
6900-430: The entire atmosphere—is ruled out because only the lower atmosphere has warmed. Atmospheric aerosols produce a smaller, cooling effect. Other drivers, such as changes in albedo , are less impactful. Greenhouse gases are transparent to sunlight , and thus allow it to pass through the atmosphere to heat the Earth's surface. The Earth radiates it as heat , and greenhouse gases absorb a portion of it. This absorption slows

7400-572: The last 14 million years. Concentrations of methane are far higher than they were over the last 800,000 years. Global human-caused greenhouse gas emissions in 2019 were equivalent to 59 billion tonnes of CO 2 . Of these emissions, 75% was CO 2 , 18% was methane , 4% was nitrous oxide, and 2% was fluorinated gases . CO 2 emissions primarily come from burning fossil fuels to provide energy for transport , manufacturing, heating , and electricity. Additional CO 2 emissions come from deforestation and industrial processes , which include
7500-436: The last two decades. CO 2 is only removed from the atmosphere for the long term when it is stored in the Earth's crust, which is a process that can take millions of years to complete. Around 30% of Earth's land area is largely unusable for humans ( glaciers , deserts , etc.), 26% is forests , 10% is shrubland and 34% is agricultural land . Deforestation is the main land use change contributor to global warming, as
7600-441: The last: internal climate variability processes can make any year 0.2 °C warmer or colder than the average. From 1998 to 2013, negative phases of two such processes, Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO) caused a short slower period of warming called the " global warming hiatus ". After the "hiatus", the opposite occurred, with years like 2023 exhibiting temperatures well above even
7700-608: The lower atmosphere. Carbon dioxide , the primary greenhouse gas driving global warming, has grown by about 50% and is at levels not seen for millions of years. Climate change has an increasingly large impact on the environment . Deserts are expanding , while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has contributed to thawing permafrost , retreat of glaciers and sea ice decline . Higher temperatures are also causing more intense storms , droughts, and other weather extremes . Rapid environmental change in mountains , coral reefs , and
7800-413: The more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate . Since the 2000s, climate change has increased usage. Various scientists, politicians and media may use the terms climate crisis or climate emergency to talk about climate change, and may use the term global heating instead of global warming . Over the last few million years
7900-634: The most recent census, was the highest concentration in Canada, now second to Nobleton ), East Indian (5,815; 5.5%), Canadian (5,655; 5.3%). Woodbridge is home to two natural preserves along the Humber River : The song " The Woodbridge Dog Disaster " by Canadian folk singer Stan Rogers , detailing a fictional occurrence in the community, was recorded in the 1970s. Climate change Present-day climate change includes both global warming —the ongoing increase in global average temperature —and its wider effects on Earth's climate . Climate change in
8000-477: The north, although this boundary appears to be expanding northwards along Highway 400 as urbanization progresses. Woodbridge has a humid continental climate ( Köppen climate classification Dfb), with warm, humid summers and cold, snowy winters. Woodbridge winters feature cold snaps where maximum temperatures remain below −10 °C (14 °F), often made to feel colder by wind chill. Accumulating snow can fall any time from October until April. Summer in Woodbridge
8100-462: The original route between Bolton and Orangeville being abandoned in 1934. By 1880, the settlement had two general stores, a carriage works, two churches, a school, two hotels, a library, two newspapers and a post office. As the population increased it was pressured by the citizens to add a post office so there would be no confusion with another settlement in Canada West . By 1882, Woodbridge had over
8200-619: The rate at which heat escapes into space, trapping heat near the Earth's surface and warming it over time. While water vapour (≈50%) and clouds (≈25%) are the biggest contributors to the greenhouse effect, they primarily change as a function of temperature and are therefore mostly considered to be feedbacks that change climate sensitivity . On the other hand, concentrations of gases such as CO 2 (≈20%), tropospheric ozone , CFCs and nitrous oxide are added or removed independently from temperature, and are therefore considered to be external forcings that change global temperatures. Before
8300-522: The rate of Arctic shrinkage and underestimated the rate of precipitation increase. Sea level rise since 1990 was underestimated in older models, but more recent models agree well with observations. The 2017 United States-published National Climate Assessment notes that "climate models may still be underestimating or missing relevant feedback processes". Additionally, climate models may be unable to adequately predict short-term regional climatic shifts. A subset of climate models add societal factors to
8400-613: The rate of yield growth . Fisheries have been negatively affected in multiple regions. While agricultural productivity has been positively affected in some high latitude areas, mid- and low-latitude areas have been negatively affected. According to the World Economic Forum, an increase in drought in certain regions could cause 3.2 million deaths from malnutrition by 2050 and stunting in children. With 2 °C warming, global livestock headcounts could decline by 7–10% by 2050, as less animal feed will be available. If
8500-422: The real world. Mission activities include improving shoreline health by organizing a cleanup, reducing energy at home by adjusting the thermostat, helping pollinators plant native flowers, and more. Once completed, children can gain rewards and unlock additional content on the Earth Rangers App. Earth Rangers delivers live and virtual school presentations for grades 1-6. The hour-long program educates children about
8600-405: The recent average. This is why the temperature change is defined in terms of a 20-year average, which reduces the noise of hot and cold years and decadal climate patterns, and detects the long-term signal. A wide range of other observations reinforce the evidence of warming. The upper atmosphere is cooling, because greenhouse gases are trapping heat near the Earth's surface, and so less heat
8700-411: The release of chemical compounds that influence clouds, and by changing wind patterns. In tropic and temperate areas the net effect is to produce significant warming, and forest restoration can make local temperatures cooler. At latitudes closer to the poles, there is a cooling effect as forest is replaced by snow-covered (and more reflective) plains. Globally, these increases in surface albedo have been
8800-476: The remaining 23%. Some forests have not been fully cleared, but were already degraded by these impacts. Restoring these forests also recovers their potential as a carbon sink. Local vegetation cover impacts how much of the sunlight gets reflected back into space ( albedo ), and how much heat is lost by evaporation . For instance, the change from a dark forest to grassland makes the surface lighter, causing it to reflect more sunlight. Deforestation can also modify
8900-583: The sea levels by at least 3.3 m (10 ft 10 in) over approximately 2000 years. Recent warming has driven many terrestrial and freshwater species poleward and towards higher altitudes . For instance, the range of hundreds of North American birds has shifted northward at an average rate of 1.5 km/year over the past 55 years. Higher atmospheric CO 2 levels and an extended growing season have resulted in global greening. However, heatwaves and drought have reduced ecosystem productivity in some regions. The future balance of these opposing effects
9000-470: The suburbs and exurbs , in particular Woodbridge. The suburban expansion began east of the Humber and East Humber and to the northeast. Prior to the expansion, the urban area was up to Kipling Avenue and to the Humber. It later expanded in the west up to present-day Martin Grove Road and north to northeast of Langstaff Road in the 1960s. It later expanded further north in the 1970s and 1980s. A drive-in theatre
9100-399: The transformation of older stores in the village into smaller units of housing) in the early 1980s and west to Highway 27 in the late 1980s and early 90s. Development extended north to just south of Rutherford Road in the 1980s and east up to Weston Road from Highway 7 to south of Rutherford Road and south to north of the present-day Highway 407 . The industrial areas began appearing first to
9200-481: The west and then to the southwest and east. After the aforementioned drive-in was closed, Martin Grove Road was extended northward through the former property to serve more developments. Woodbridge Highlands was formed in the northwest, east of Highway 27 in the 1990s. In 1994 housing developments reached to Rutherford and continued until 1996 except for the northeast and the southeastern part. The condominiums began construction and now appear between Woodbridge Avenue and
9300-438: The world. Impacts can be observed on all continents and ocean regions, with low-latitude, less developed areas facing the greatest risk. Continued warming has potentially "severe, pervasive and irreversible impacts" for people and ecosystems. The risks are unevenly distributed, but are generally greater for disadvantaged people in developing and developed countries. The World Health Organization calls climate change one of
9400-558: The world. The Earth Rangers Podcast was listed as one of the Best Canadian Podcasts of the Year in 2018 by Apple, and also won the 2018 Gold - Audio Experience from Mom's Choice Awards. The Big Melt is for preteens and teens, and focuses on climate change and its solutions. Both podcasts include interviews with a variety of guests, including wildlife and climate experts, authors, researchers, and students. The Wild Wire Blog
9500-506: The year 2050. Children can participate in Project 2050 by logging the provided climate-friendly habits daily through the Earth Rangers App or website. Habits may include unplugging unused electronics, composting, turning off lights, and walking instead of driving. As habits are logged, members collectively attempt to reach set community goals to unlock special rewards. Wildlife adoptions are symbolic animal adoptions that can be purchased as either
9600-559: Was also suitable due to the many bridges in the area across the Humber River. Woodbridge eventually overtook, and later included, nearby Pine Grove after it was incorporated in 1882. Brownsville also became part of Woodbridge. John Abell was another notable early entrepreneurial figure that shaped the village of Burwick/Woodbridge. A major industry over time, Abell Agricultural Works opened in 1862 and had 200 employees by 1874, making steam-powered agricultural equipment. The Toronto, Grey and Bruce Railway arrived from Weston in 1870. This line
9700-559: Was constructed as a narrow gauge railway through Caledon and completed to Owen Sound in 1873. Owing to financial difficulty, it was operated by the Grand Trunk Railway until 1883, when it was leased to the Canadian Pacific Railway . Conversion to standard gauge required realigning some of the track curves, particularly around Woodbridge. In 1908 this line was linked to the transcontinental route through Sudbury , with
9800-572: Was once an independent village before being amalgamated with nearby communities to form the city in 1971. Its traditional downtown core is the Woodbridge Avenue stretch between Islington Avenue and Kipling Avenue north of Highway 7 . The community had its origins with the British Crown granting the west half of lots six and seven, concession 7 of Vaughan Township to Jacob Philips and Hugh Cameron in 1802. Woodbridge had its beginnings in what
9900-524: Was sending more energy to Earth, but instead, it has been cooling. This is consistent with greenhouse gases preventing heat from leaving the Earth's atmosphere. Explosive volcanic eruptions can release gases, dust and ash that partially block sunlight and reduce temperatures, or they can send water vapour into the atmosphere, which adds to greenhouse gases and increases temperatures. These impacts on temperature only last for several years, because both water vapour and volcanic material have low persistence in
10000-471: Was situated on Langstaff Road east of Highway 27. Operating from 1967 to 1997, the site was developed for housing in 1998. The Village of Woodbridge, along with other communities within Vaughan Township, was amalgamated to form the new Town (now City) of Vaughan in 1971. The housing developments in the west expanded north to Langstaff. Development continued in the central part of Woodbridge (including
