Special Report on Global Warming of 1.5 °C

  (Redirected from Special Report on Global Warming of 1.5ºC)

Cover of the Special Report on Global Warming of 1.5 °C

The Special Report on Global Warming of 1.5 °C (SR15)[note 1] was published by the Intergovernmental Panel on Climate Change (IPCC) on 8 October 2018.[1] The report, approved in Incheon, South Korea, includes over 6,000 scientific references, and was prepared by 91 authors from 40 countries.[2] In December 2015, the 2015 United Nations Climate Change Conference called for the report.[2] The report was delivered at the United Nations' 48th session of the IPCC to "deliver the authoritative, scientific guide for governments" to deal with climate change.[3]

Its key finding is that meeting a 1.5 °C (2.7 °F) target is possible but would require "deep emissions reductions"[4] and "rapid, far-reaching and unprecedented changes in all aspects of society."[2] Furthermore, the report finds that that "limiting global warming to 1.5 °C compared with 2 °C would reduce challenging impacts on ecosystems, human health and well-being" and that a 2 °C temperature increase would exasperate extreme weather, rising sea levels and diminishing Arctic sea ice, coral bleaching, and loss of ecosystems, among other impacts.[2] SR15 also has modelling that shows that "Global net human-caused emissions of carbon dioxide (CO2) would need to fall by about 45 percent from 2010 levels by 2030, reaching 'net zero' around 2050."[2] The reduction of emissions by 2030 and its associated changes and challenges, including rapid decarbonisation, was a key focus on much of the reporting which was repeated through the world.[5][6][7][8][9][10]


Main StatementsEdit

Global warming will likely rise to 1.5 °C above pre-industrial levels between 2030 and 2052 if warming continues to increase at the current rate.[4][11] SR15 provides a summary of, on one hand, existing research on the impact that a warming of 1.5 °C (equivalent to 2.7 °F) would have on the planet, and on the other hand, the necessary steps to limit global warming.[12]

Even assuming full implementation of conditional and unconditional Nationally Determined Contributions submitted by nations in the Paris Agreement, net emissions would increase compared to 2010, leading to a warming of about 3 °C by 2100, and more afterwards.[13][14] In contrast, limiting warming below or close to 1.5 °C would require to decrease net emissions by around 45% until 2030 and reach net zero by 2050 (i.e. keeping total cumulative emissions within a carbon budget). Even just for limiting global warming to below 2 °C, CO2 emissions should decline by 25% until 2030 and by 100% until 2075.[15]

Pathways (i.e. scenarios and portfolios of mitigation options) that would allow such reduction by 2050 permit only about 8% of global electricity to be generated by gas and 0-2% by coal (to be offset by carbon dioxide capture and storage). In these pathways, renewables are projected to supply 70–85% of electricity in 2050 and the shares of nuclear energy is modelled to increase.[16] They also assume that other measures are simultaneously undertaken: e.g. non-CO2 emissions (such as methane, black carbon, nitrous oxide) are to be similarly reduced,[17] energy demand is unchanged, reduced by even 30% or offsetted by an unprecedented scale of carbon dioxide removal methods yet to be developed, while new policies and research allows to improve efficiency in agriculture and industry.[18]

Pathways limiting global warming to 1.5 °C with no or limited overshoot would require rapid and far-reaching transitions in energy, land, urban and infrastructure (including transport and buildings), and industrial systems. These systems transitions are unprecedented in terms of scale, but not necessarily in terms of speed, and imply deep emissions reductions in all sectors, a wide portfolio of mitigation options and a significant upscaling of investments in those options. The rates of system changes […] have occurred in the past within specific sectors, technologies and spatial contexts, but there is no documented historic precedent for their scale. — IPCC, SR15 Summary for policymakers, p. 17[19]

Impact of 1.5 °C or 2 °C warmingEdit

According to the report, with global warming of 1.5 °C there would be increased risks to "health, livelihoods, food security, water supply, human security, and economic growth."[4] Impact vectors include reduction in crop yields and nutritional quality. Livestock are also affected with rising temperatures through "changes in feed quality, spread of diseases, and water resource availability." "Risks from some vector-borne diseases, such as malaria and dengue fever, are projected to increase."[20]

"Limiting global warming to 1.5°C, compared with 2°C, could reduce the number of people both exposed to climate-related risks and susceptible to poverty by up to several hundred million by 2050."[21] Climate-related risks associated with increasing global warming depend on geographic location, "levels of development and vulnerability", and the speed and reach of climate mitigation and climate adaptation practices.[4] For example, "urban heat islands amplify the impacts of heatwaves in cities." In general, "countries in the tropics and Southern Hemisphere subtropics are projected to experience the largest impacts on economic growth."[22]

Weather, sea level, iceEdit

Many regions and seasons experience warming greater than the global annual average, e.g. "2–3 times higher in the Arctic. Warming is generally higher over land than over the ocean,"[23] and it correlates with temperature extremes (which are projected to warm up to twice more on land than the global mean surface temperature) as well as precipitation extremes (both heavy rain and droughts).[24] The assessed levels of risk generally increased compared to the previous IPCC report.[25]

The "global mean sea level is projected rise (relative to 1986-2005) by 0.26 to 0.77 m by 2100 for 1.5 °C global warming" and about 0.1 m more for 2 °C. A difference of 0.1 m may correspond to 10 million more or fewer people exposed to related risks.[26] "Sea level rise will continue beyond 2100 even if global warming is limited to 1.5 °C. Around 1.5 °C to 2 °C of global warming," irreversible instabilities could be triggered in Antarctica and "Greenland ice sheet, resulting in multi-metre rise in sea level."[27] "An ice-free Arctic summer is projected once per century" (per decade) for 1.5 °C (respectively 2 °C).[28] "Limiting global warming to 1.5 °C rather than 2 °C is projected to prevent the thawing over centuries of a permafrost area in the range of 1.5 to 2.5 million km2."[29]


"A decrease in global annual catch for marine fisheries of about 1.5 or 3 million tonnes for 1.5 °C or 2 °C of global warming" is projected by one global fishery model cited in the report.[30] Coral reefs are projected to decline by a further 70–90% at 1.5 °C, and even more than 99% at 2 °C.[31] "Of 105,000 species studied, 18% of insects, 16% of plants and 8% of vertebrates fare projected to lose over half of their climatically determined geographic range for global warming of 2 °C."[32]

Approximately "4% or 13% of the global terrestrial land area is projected to undergo a transformation of ecosystems from one type to another" at 1 °C or 2 °C, respectively. "High-latitude tundra and boreal forests are particularly at risk of climate change-induced degradation and loss, with woody shrubs already encroaching into the tundra and will proceed with further warming."[33]

Limiting the temperature increaseEdit

Human activities (anthropogenic greenhouse gas emissions) have already contributed 0.8–1.2 °C (1.4–2.2 °F) of warming.[4] Nevertheless, the gases which have been emitted so far are unlikely to cause global temperature to rise to 1.5 °C alone, meaning a global temperature rise to 1.5 °C above pre-industrial levels is avoidable, assuming net zero emissions are eventually reached.[34][35]

Carbon budgetEdit

Limiting global warming to 1.5 °C requires staying within a total carbon budget, i.e. limiting total cumulative emissions of CO2.[36] In other words, if net anthropogenic CO2 emissions are kept above zero, a global warming of 1.5 °C and more will eventually be reached.

The exact value of the this budget is not assessed in the report,[37] but estimates of 400–800 GtCO2 (gigatonnes of CO2) remaining budget are given (580 GtCO2 and 420 GtCO2 for a 66% and 50% probability of limiting warming to 1.5 °C, using global mean surface air temperature (GSAT); or 770 and 570 GtCO2, for 50% and 66% probabilities, using global mean surface temperature (GMST)). This is about 300 GtCO2 more compared to a previous IPCC report, due to updated understanding and further advances in methods.

Current emissions deplete this budget at 42±3 GtCO2 per year. Anthropogenic emissions from the pre-industrial period to the end of 2017 are estimated to have reduced the budget for 1.5 °C by approximately 2200±320 GtCO2.[36]

The estimates for the budget come with significant uncertainties, associated with: climate response to CO2 and non-CO2 emissions (these contribute about ±400 GtCO2 in uncertainty), the level of historic warming (±250 GtCO2), potential additional carbon release from future permafrost thawing and methane release from wetlands (reducing the budget by up to 100 GtCO2 over the century), and the level of future non-CO2 mitigation (±400 GtCO2).[36]

Necessary emission reductionsEdit

Current nationally stated mitigation ambitions, as submitted under the Paris Agreement, would lead to global greenhouse gas emissions of 52–58 GtCO2eq per year, by 2030. "Pathways reflecting these ambitions would not limit global warming to 1.5 °C, even if supplemented by very challenging increases in the scale and ambition of emissions reductions after 2030."[13] Instead, they are "broadly consistent" with a warming of about 3 °C by 2100, and more afterwards.

Limit global warming to 1.5 °C with no or limited overshoot would require reducing emissions to below 35 GtCO2eq per year in 2030, regardless of the modelling pathway chosen. Most fall within 25–30 GtCO2eq per yer, a 40–50% reduction from 2010 levels.[38]

The report says that for limiting warming to below 1.5 C "global net human-caused emissions of CO2 would need to fall by about 45% from 2010 levels by 2030, reaching net zero around 2050." Even just for limiting global warming to below 2 °C, CO2 emissions should decline by 25% until 2030 and by 100% until 2075.[15]

Non-CO2 emissions should decline in more or less similar ways.[18] This involves deep reductions in emissions of methane and black carbon: at least 35% of both by 2050, relative to 2010, to limit warming near 1.5 °C. Such measures could be undertaken in the energy sector and by reducing nitrous oxide and methane from agriculture, methane from the waste sector, and some other sources of black carbon and hydrofluorocarbons.[17]

On timescales longer than tens of years, it may still be necessary to sustain net negative CO2 emissions and/or further reduce non-CO2 radiative forcing, in order to prevent further warming (due to Earth system feedbacks), reverse ocean acidification, and minimise sea level rise.[39]

Pathways to 1.5 °CEdit

Various pathways are considered, describing scenarios for mitigation of global warming, including portfolios for energy supply and negative emission technologies (like afforestation or carbon dioxide removal).

Examples of actions consistent with the 1.5 °C pathway include "shifting to low- or zero-emission power generation, such as renewables; changing food systems, such as diet changes away from land-intensive animal products; electrifying transport and developing ‘green infrastructure’, such as building green roofs, or improving energy efficiency by smart urban planning, which will change the layout of many cities."[40] As another example, an increase of forestation by 10,000,000 square kilometres (3,900,000 sq mi) by 2050 relative to 2010 would be required.[41]

The pathways also assume an increase in annual investments in low-carbon energy technologies and energy efficiency by roughly a factor of four to ten by 2050 compared to 2015.[42]

Negative emission technologies and geoengineeringEdit

The emission pathways that reach 1.5 °C contained in the report assume the use of negative emission technology to offset for remaining emissions.[43] Pathways that overshoot the goal rely on them to exceed remaining emissions in order to return back to 1.5 °C.[44] However, understanding is still limited about the effectiveness of net negative emissions to reduce temperatures after an overshoot. Reversing an overshoot of 0.2°C might not be achievable given considerable implementation challenges.[45]

There are two main groups of geoengineering types in the report, carbon dioxide removal (CDR) and solar radiation management (SRM). For CDR the report highlights bioenergy with carbon capture and storage (BECCS). The report notes that apart from afforestation/reforestation and ecosystem restoration, "the feasibility of massive-scale deployment of many CDR technologies remains an open question", with areas of uncertainty regarding technology upscaling, governance, ethical issues, policy and carbon cycle.[46][47] The report notes that CDR technology is in its infancy and the feasibility is an open question. Estimates from recent literature are cited, giving a potential of up to 5 GtCO2 per year for BECCS and up to 3.6 GtCO2 per year for afforestation.[48] An analysis of the geoengineering proposals published in Nature Communication confirmed findings of the SR15, stating that "all are in early stages of development, involve substantial uncertainties and risks, and raise ethical and governance dilemmas. Based on present knowledge, climate geoengineering techniques cannot be relied on to significantly contribute to meeting the Paris Agreement temperature goals".[49]

As for SRM, the report focuses on stratospheric aerosol injection, as it has the most available literature; however it is still an experimental technology.[50] SRMs also "face large uncertainties and knowledge gaps as well as substantial risks, […] and constraints";[51] "the impacts of SRM (both biophysical and societal), costs, technical feasibility, governance and ethical issues associated need to be carefully considered."[47]


There are three IPCC working groups: Working Group I (WG I), co-chaired by Valerie Masson-Delmotte and Panmao Zhai, covers the physical science of climate change. Working Group II (WG II), co-chaired by Hans-Otto Pörtner and Debra Roberts, examines "impacts, adaptation and vulnerability". The "mitigation of climate change" is dealt with by Working Group III (WG III), co-chaired by Priyardarshi Shukla and Jim Skea.[52] The "Task Force on National Greenhouse Gas Inventories" "develops methodologies for measuring emissions and removals". There are also Technical Support Units that guide "the production of IPCC assessment reports and other products".[53]


Researchers from 40 countries, representing 91 authors and editors contributed to the report, which includes over 6,000 scientific references.[1][54][55]



In his 1 October 2018 opening statement at the 48th Session held in Incheon, Korea, Hoesung Lee, who has been Chair of the IPCC since 6 October 2015,[56] described this IPCC meeting as "one of the most important" in its history.[57][3] Debra Roberts, IPCC contributor called it the "largest clarion bell from the science community". Roberts hopes "it mobilises people and dents the mood of complacency."[58]

In a CBC interview, Paul Romer was asked if the Nobel Prize in economic sciences that he and William Nordhaus received shortly before the SR15 was released, was timed as a message. Romer said that he was optimistic that measures will be taken in time to avert climate catastrophe. Romer compared the angst and lack of political will in imposing a carbon tax to the initial angst surrounding the chlorofluorocarbon (CFC) ban and the positive impact it had on restoring the depleted ozone layer.[note 2][59] In giving the Nobel to Nordhaus and Romer, the Royal Swedish Academy of Sciences cited Nordhaus as saying "the most efficient remedy for problems caused by greenhouse gases is a global scheme of universally imposed carbon taxes".[60]

Howard J. Herzog, a senior research engineer at the Massachusetts Institute of Technology, said that carbon capture and storage technologies, except reforestation, are problematic because of their impact on the environment, health and high cost.[61] In the article there is a link to another article that refers to a study published in the scientific journal "Nature Energy". The study says that we can limit warming to 1.5 degrees without carbon capture and storage, by technological innovation and changing lifestyle.[62]



Prime Minister Scott Morrison emphasised that the report was not specifically for Australia but for the whole world.[63] Energy Minister Angus Taylor said the Government would "not be distracted” by the IPCC report saying "A debate about climate change and generation technologies in 2050 won't bring down current power prices for Australian households and small businesses.”[63] Environment Minister Melissa Price said that scientists are “drawing a very long bow” to say coal should be phased out by 2050 and supported new coal-fired power stations pledging not to legislate the Paris targets.[64][65] Australia is not on track to meet the commitments under Paris agreement according to modelling conducted by ClimateWorks Australia.[66][67][68]


Canadian Environment Minister Catherine McKenna acknowledged that the SR15 report would say Canada is not "on track" for 1.5 °C.[69] Canada will not be implementing new plans but it will continue to move forward on a "national price on carbon, eliminating coal-fired power plants, making homes and businesses more energy-efficient, and investing in clean technologies and renewable energy". In response to a question on the sense of urgency of the SR15 report during a 9 October interview on CBC News's Power and Politics Andrew Scheer, the Leader of the Opposition, promised that they are putting forward a "comprehensive plan to reduce CO2 without imposing a carbon tax" which Scheer said "raised costs without actually reducing emissions."[70]

European UnionEdit

According to The New York Times, the European Union indicated it might add more ambitious reform goals centered around reducing emissions.[71] On 9 October, the Council of the European Union presented their response to SR15 and their position for the Katowice Climate Change Conference of the Parties (COP 24) to be held in Poland in December 2018.[72] Their environment ministers noted recent progress in legislation to reduce greenhouse gas emissions.[72][note 3]


The Centre for Science and Environment said the repercussions for developing countries such as India, would be "catastrophic" at 2 °C warming and that the impact even at 1.5 °C described in SR15 is much greater than anticipated. Crop yields would decline and poverty would increase.[73]

New ZealandEdit

The Minister for Climate Change James Shaw said that the Report "has laid out a strong case for countries to make every effort to limit temperature rise to 1.5° Celsius above pre-industrial levels. ... The good news is that the IPCC's report is broadly in line with this Government's direction on climate change and it's highly relevant to the work we are doing with the Zero Carbon Bill."[74]

United StatesEdit

President Donald Trump said that he had received the report, but wanted to learn more about those who "drew it" before offering conclusions.[10] In an interview with ABC's "This Week" the director of the National Economic Council, Larry Kudlow, stated, "personally, I think the UN study is way too difficult," and that the authors "overestimate" the likelihood for environmental disasters.[75] Since the publication Trump stated in an interview on 60 Minutes that he didn't know that climate change is manmade and that "it'll change back again", the scientists who say it's worse than ever have "a very big political agenda" and that “we have scientists that disagree with [manmade climate change].”[76]

  3. ^ The Council's 9 October pointed to climate change legislation such as, the "new EU 2030 renewable energy target of 32%, the new energy efficiency target of 32.5%, the reform of the EU emission trading system, the emission reduction targets in sectors falling outside the scope of ETS and the integration of land use, land use change and forestry (LULUCF) in the EU's climate and energy framework. Low-emissions and climate resilient growth is possible: The EU is continuing successfully to decouple economic growth from emissions. Between 1990 and 2016, the EU's GDP grew by 53% while total emissions fell by 22.4%. The EU's share of global greenhouse gas emissions fell from an estimated 17.3% in 1990 to 9.9% in 2012.
