This is an environmental history of the 2020s. Environmental history refers to events and trends related to the natural environment and human interactions with it. Examples of human-induced events include biodiversity loss, climate change and holocene extinction.
As of July 2020 [update] , neither the International Commission on Stratigraphy (ICS) nor the International Union of Geological Sciences (IUGS) has officially approved the term as a recognized subdivision of geologic time, [1] [2] [3] but in May 2019, the AWG voted in favor of submitting a formal proposal to the ICS by 2021, [4] locating potential stratigraphic markers to the mid-twentieth century of the common era. [5] [4] [6]
According to the 2020 United Nations' Global Biodiversity Outlook report, of the 20 biodiversity goals laid out by the Aichi Biodiversity Targets in 2010, only 6 were "partially achieved" by the deadline of 2020. [7] The report highlighted that if the status quo is not changed, biodiversity will continue to decline due to "currently unsustainable patterns of production and consumption, population growth and technological developments". [8] The report also singled out Australia, Brazil and Cameroon and the Galapagos Islands (Ecuador) for having had one of its animals lost to extinction in the past 10 years. [9] Following this, the leaders of 64 nations and the European Union pledged to halt environmental degradation and restore the natural world. Leaders from some of the world's biggest polluters, namely China, India, Russia, Brazil, and the United States, were not among them. [10]
The effects of climate change manifested in 2020 with a record 30 named Atlantic tropical storms and hurricanes; the highest heat in 80-years recorded at 54.4 Celsius; massive wildfires in Australia, the Western United States, and the Arctic; and the second-lowest annual Arctic sea ice coverage. [11]
A hundred people died and 18,000 were hospitalized in Japan while France reported 1,462 heat-related deaths in 2019, an El Niño year. 2,800,000 people came down with dengue, leading to 1,250 deaths. [12]
The Milne Ice Shelf, on Ellesmere Island in the northern Canadian territory of Nunavut, collapsed in two days at the end of July 2020. This was the last fully intact Arctic ice shelf. [13]
Environmental groups declared that 2020 was at or near the hottest year on record. NASA said 2020 was tied with 2016, but NOAA said it was the second or third. NOAA said 2020 averaged 58.77 °F (14.88 °C), a few hundredths of a degree behind 2016. Other groups (World Meteorological Organization, Copernicus Group, UK Meteorological Office) had slightly different measurements. The differences in rankings mainly occurred due to how scientists accounted for data gaps in the Arctic; the difference between first or second place is considered insignificant. [14]
According to the World Wide Fund for Nature's 2020 Living Planet Report , wildlife populations have declined by 68% since 1970 as a result of overconsumption, population growth and intensive farming, which is further evidence that humans have unleashed a sixth mass extinction event. [16] [17] [18]
Earthquakes and tsunamis during the decade include the 2020 Caribbean earthquake and the 2020 Zagreb earthquake. Wildfires included the 2019–20 Australian bushfire season, 2020 Western United States wildfire season, 2020 Córdoba wildfires, and as well as 2021 Turkey wildfires.
Major tropical storms and hurricanes have also made an appearance during the decade, such as Hurricane Ida and Hurricane Ian. The more-than-average amounts of rainfall, higher ground covered, and the intensifying high-speed winds that accompanied both hurricanes were indirectly alleged to be products of rising sea levels and higher atmospheric temperatures. [19] [20]
In 2020, a huge swarm of desert locusts threatened to engulf massive portions of the Middle East, Africa, and Asia. [21] [22] In tandem with the COVID-19 pandemic, this posed major hazards to billions of people who might be affected. Although experts had thought the insects would die out during the dry season in December 2019, unseasonal rains caused the incursion to reach unanticipated and hazardous levels. [23] [24] [25] [26]
The 2019–2022 locust infestation caused widespread devastation of food production in the Horn of Africa.
An extreme heat wave in Western North America began affecting much of the Pacific Northwest and Western Canada in late June 2021. The heat has affected northern California, Idaho, western Nevada, Oregon, and Washington in the United States, as well as British Columbia, and, in its later phase, Alberta, Manitoba, the Northwest Territories, Saskatchewan, and Yukon, all in Canada. [27] It resulted in some of the highest temperatures ever recorded in the region, [28] including the highest temperature ever measured in Canada at 49.6 °C (121.3 °F).
Hurricane Eta and Hurricane Iota (both Category 4) hit the region in November within weeks of each other, creating much devastation to the same areas. At least 250 people were killed, with billions of dollars of damage to property.
The 2020 Aegean Sea earthquake killed 117 people in İzmir (in addition to two in Greece) after 41 had died in the Elazığ earthquake in the same year, while the 2020 Iran–Turkey earthquakes killed 10. Forty-one people were also killed by the 2020 Van avalanches.
Over two hundred wildfires burnt 1,600 square kilometres of Turkey's forest in its Mediterranean Region in July and August 2021, [29] the worst ever wildfire season in the country's history. [30]
In July 2021, several European countries were affected by catastrophic floods, causing deaths and widespread damage. The floods affected several river basins, first in the United Kingdom and later across northern and central Europe including Belgium, Germany, Luxembourg, the Netherlands, Switzerland and Italy. [31] At least 185 people died in the floods, including 157 in Germany, 27 in Belgium and one in Italy. [32] [33] [34]
Milieudefensie v Royal Dutch Shell was a case heard by the district court of The Hague in the Netherlands in 2021 related to efforts by multinational corporations to curtail carbon dioxide emissions. The case was considered a landmark ruling in environmental law related to climate change: while previous lawsuits against governments have prevailed for improving emissions, this was considered the first major suit to hold a corporation to the tenets of the Paris Agreement. [35] While the decision only has jurisdiction in the Netherlands, [36] it is expected to set a precedent for other environmental lawsuits against other large companies with high emissions that have not taken sufficient steps to reduce their emissions. [37] [38] [39] [40] [41] The impact of the court's decision was considered by legal experts to be strengthened due to its reliance on human rights standards and international measures on climate change. [42] [35] [37]
The Norilsk oil spill was an industrial disaster near Norilsk, Krasnoyarsk Krai, that began on 29 May 2020 when a fuel storage tank at Norilsk-Taimyr Energy's Thermal Power Plant No. 3 (owned by Nornickel) failed, flooding local rivers with up to 21,000 cubic metres (17,500 tonnes) of diesel oil. [43] [44] Russian President Vladimir Putin declared a state of emergency in early June. [45] The accident has been described as the second-largest oil spill in modern Russian history. [46] As a result of the spill, up to 21,000 cubic metres (17,500 tonnes) of diesel oil spilled into the Daldykan River. Greenpeace Russia compared the potential environmental effects of the Norilsk spill to that of the 1989 Exxon Valdez oil spill. [43] In the aftermath of the Norilsk spill, Russia's Prosecutor General's office ordered safety checks at all dangerous installations built on the permafrost in Russia's Arctic. [47]
From June 2021, the taiga forests in Siberia and the Far East region of Russia were hit by unprecedented wildfires, following record-breaking heat and drought. [48] For the first time in recorded history, wildfire smoke reached the North Pole. [49] Causes of the fires include monitoring difficulties, [50] the shifting patterns of the jet stream and climate change in Russia. [51] Large amounts of carbon may be released from formerly frozen ground under the fires, [52] especially peatlands [53] which continued burning from the previous year. [54]
The 2019–20 Australian bushfire season was particularly destructive, killing at least 28 and destroying no fewer than 3,000 homes. The fires were widespread, but New South Wales (NSW) was the hardest hit. In December 2019 the smoke around Sydney was so bad that air quality was 11 times the "hazardous" level and temperatures were over 40 °C (113°-120 °F). Natural causes such as lightning strikes started most of the fires, which were exasperated by dry conditions and drought, although police in NSW arrested at least 24 people for deliberately starting fires. In total, 7.3 million hectares (17.9 million acres) have burned across Australia's six states—an area larger than Belgium and Denmark combined. Experts estimate 500 million animals died, not including bats, frogs, or insects; one-third of Australia's koalas were killed, according to Minister for the Environment Sussan Ley. [55]
Permafrost is soil or underwater sediment which continuously remains below 0 °C (32 °F) for two years or more: the oldest permafrost had been continuously frozen for around 700,000 years. Whilst the shallowest permafrost has a vertical extent of below a meter (3 ft), the deepest is greater than 1,500 m (4,900 ft). Similarly, the area of individual permafrost zones may be limited to narrow mountain summits or extend across vast Arctic regions. The ground beneath glaciers and ice sheets is not usually defined as permafrost, so on land, permafrost is generally located beneath a so-called active layer of soil which freezes and thaws depending on the season.
An environmental disaster or ecological disaster is defined as a catastrophic event regarding the natural environment that is due to human activity. This point distinguishes environmental disasters from other disturbances such as natural disasters and intentional acts of war such as nuclear bombings.
Norilsk is a closed city in Krasnoyarsk Krai, Russia, located south of the western Taymyr Peninsula, around 90 km east of the Yenisey River and 1,500 km north of Krasnoyarsk. Norilsk is 300 km north of the Arctic Circle and 2,400 km from the North Pole. It has a permanent population of 176,735 as of 2024, and up to 220,000 including temporary inhabitants. It is the second-largest city in the region after Krasnoyarsk. Since 2016, Norilsk's population has grown steadily. In 2017, for the first time, migration to the city exceeded outflow. In 2018, according to Krasnoyarskstat, natural population growth amounted to 1,357 people: 2,381 were born, and 1,024 died.
Environmental issues in Nepal include a number of issues, such as deforestation, climate change, energy and species conservation. Many of these issues have been precipitated by rapid industrialization without major environmental regulation.
Norilsk Nickel, or Nornickel, is a Russian nickel and palladium mining and smelting company. Its largest operations are located in the Norilsk–Talnakh area near the Yenisei River in the north of Siberia. It also has holdings in Nikel, Zapolyarny, and Monchegorsk on the Kola Peninsula, in Harjavalta in western Finland, and in South Africa.
The natural environment, commonly referred to simply as the environment, is all living and non-living things that occur naturally on Earth or some part of it. This includes complete ecological units that function as natural systems without massive human intervention, including all vegetation, animals, microorganisms, rocks, atmosphere and natural phenomena that occur within their boundaries. And it includes universal natural resources and physical phenomena that lack clear-cut boundaries, such as air, water, and climate, as well as energy, radiation, electric charge, and magnetism, not originating from human activity.
Environmental issues in Canada include impacts of climate change, air and water pollution, mining, logging, and the degradation of natural habitats. As one of the world's significant emitters of greenhouse gasses, Canada has the potential to make contributions to curbing climate change with its environmental policies and conservation efforts.
Climate change has led to the United States warming by 2.6 °F since 1970. The climate of the United States is shifting in ways that are widespread and varied between regions. From 2010 to 2019, the United States experienced its hottest decade on record. Extreme weather events, invasive species, floods and droughts are increasing. Climate change's impacts on tropical cyclones and sea level rise also affect regions of the country.
Climate change has serious effects on Russia's climate, including average temperatures and precipitation, as well as permafrost melting, more frequent wildfires, flooding and heatwaves. Changes may affect inland flash floods, more frequent coastal flooding and increased erosion reduced snow cover and glacier melting, and may ultimately lead to species losses and changes in ecosystem functioning.
The environmental impact of the petroleum industry is extensive and expansive due to petroleum having many uses. Crude oil and natural gas are primary energy and raw material sources that enable numerous aspects of modern daily life and the world economy. Their supply has grown quickly over the last 150 years to meet the demands of the rapidly increasing human population, creativity, knowledge, and consumerism.
Climate change is greatly impacting Canada's environment and landscapes. Extreme weather has become more frequent and severe because of the continued release of greenhouse gases into the atmosphere. The number of climate change–related events, such as the 2021 British Columbia Floods and an increasing number of forest fires, has become an increasing concern over time. Canada's annual average temperature over land warmed by 1.7 degrees Celsius between 1948 and 2016. The rate of warming is highest in Canada's north, the Prairies, and northern British Columbia. The country's precipitation has increased in recent years and wildfires expanded from seasonal events to year-round threats.
Climate change has resulted in an increase in temperature of 2.3 °C (4.14 °F) (2022) in Europe compared to pre-industrial levels. Europe is the fastest warming continent in the world. Europe's climate is getting warmer due to anthropogenic activity. According to international climate experts, global temperature rise should not exceed 2 °C to prevent the most dangerous consequences of climate change; without reduction in greenhouse gas emissions, this could happen before 2050. Climate change has implications for all regions of Europe, with the extent and nature of impacts varying across the continent.
Italy is experiencing widespread impacts of climate change, with an increase in extreme events such as heatwaves, droughts and more frequent flooding; for example, Venice is facing increasing issues due to sea level rise. Italy faces many challenges adapting to climate change including the economic, social, and environmental impacts that climate change creates, and an increasingly problematic death toll from the health risks that come with climate change.
The Canadian province of Alberta faces a number of environmental issues related to natural resource extraction—including oil and gas industry with its oil sands—endangered species, melting glaciers in banff, floods and droughts, wildfires, and global climate change. While the oil and gas industries generates substantial economic wealth, the Athabasca oil sands, which are situated almost entirely in Alberta, are the "fourth most carbon intensive on the planet behind Algeria, Venezuela and Cameroon" according to an August 8, 2018 article in the American Association for the Advancement of Science's journal Science. This article details some of the environmental issues including past ecological disasters in Alberta and describes some of the efforts at the municipal, provincial and federal level to mitigate the risks and impacts.
This is an article of notable issues relating to the environment in 2019. They relate to environmental law, conservation, environmentalism and environmental issues.
The Norilsk diesel oil spill was an industrial disaster near Norilsk, Krasnoyarsk Krai, Russia. It began on 29 May 2020 when a fuel storage tank at Norilsk-Taimyr Energy's Thermal Power Plant No. 3 failed, flooding local rivers with up to 17,500 tonnes of diesel oil. President Vladimir Putin declared a state of emergency in early June. The incident has been described as the second-largest oil spill in modern Russian history, after the 1994 Komi pipeline spill, where 400,000 tonnes of crude oil were released to the environment between August 1994 and January 1995.
The Federal Service for Supervision of Natural Resources is the Federal Environmental, Industrial and Nuclear Supervision Service of Russia. This regulator is part of the Ministry of Natural Resources of the Russian Federation.
This article documents events, research findings, scientific and technological advances, and human actions to measure, predict, mitigate, and adapt to the effects of global warming and climate change—during the year 2020.
The Russian invasion of Ukraine has led to ongoing widespread and possibly serious and long-term environmental damage. The Ukrainian government, journalists and international observers describe the damage as ecocide.
