Climate Change in Israel

Israel spans Mediterranean, semi-arid, and arid climates within a regional climate-change hotspot, making warming and changes in water availability important across markedly different environments.[3] Its three principal climate regions are hot-summer Mediterranean, hot semi-arid, and hot arid; rainfall falls steeply from the western mountain ridge toward the Jordan Rift Valley, while spatial and year-to-year uncertainty increases toward the southeast.[4] Climate risks therefore connect national systems—particularly water, electricity, food production, and public services—while differing considerably between localities.[1]

The established seasonal pattern consists of a cool, rainy winter from October through April and a hot, dry summer from May through September.[5] Annual precipitation ranges from approximately 25 millimeters in the Arava Valley to as much as 1,120 millimeters in the Upper Galilee, and late or insufficient winter rain can produce severe summer water shortages.[5] Another description, measuring rainfall at sea level across roughly 420 kilometers, gives a north–south range from 800 millimeters to less than 50 millimeters.[6] Virtually all precipitation falls during the cool months, while high evaporation characterizes the summer.[6]

Recent national reporting illustrates this geographic variation with 1991–2020 annual averages of 688 millimeters in Safed, 557 in Tel Aviv, 192 in Be’er Sheva, and 23 in Eilat.[1] National rainfall volumes also fluctuate substantially: the recorded total was 4.5 billion cubic meters in 2016–2017 and 8.44 billion in 2019–2020.[1] In 2021–2022, central Israel and parts of the north received above-average rainfall while the south remained below average.[1]

The wider Mediterranean is a climate-sensitive transition between humid or cold temperate environments and hot desert zones.[7] Regional research identifies twentieth-century warming and decreases in winter precipitation, with patterns varying by subregion and period.[7] Across the Middle East and North Africa, rising temperatures compound existing water stress and can increase cooling demand while harming health, labor, and agricultural productivity.[8] Regional projections also indicate a growing water deficit, driven substantially by higher temperatures rather than reduced rainfall alone.[7]

A study of 12 Israeli meteorological stations covering 1970–2002 found significant warming at every station.[9] Average annual precipitation and the aridity index remained approximately stable along the Mediterranean coast but declined farther inland, eastward, and southward; the study concluded that most of Israel had become more arid, with the coastal plain as the exception.[9]

Between 1950 and 2017, Israel’s annual mean temperature increased by 1.4°C, with systematic warming beginning in the 1980s.[10] During the final three decades of that period, the warming rate was approximately 0.53°C per decade, faster than the roughly 1°C global increase over the preceding 130 years used in that comparison.[10] More recent national reporting gives a rate of approximately 0.6°C per decade over the preceding 30 years, compared with a global average of about 0.22°C per decade during 1991–2020.[1] Although 2022 was cooler than the preceding decade’s average, it remained 0.9°C warmer than the 1961–1990 average.[1]

Observations from 1950–2023 also show recurring exposure to excessive heat during most summer noon hours, with the heat index frequently exceeding a study-defined physiologically no-risk threshold.[11] A comparison of summertime decadal means since the beginning of the twenty-first century with the 1950s yielded reported increases of 0.06°C per year in ambient noontime temperature, 0.06 grams per cubic meter per year in absolute humidity, and 0.09°C per year in the heat index.[11] Landsat observations for 1984–2021 showed eastern Mediterranean sea-surface warming of 0.05°C per year, helping explain the associated humidity increase and worsening thermal discomfort.[11]

Observations have recorded more days above 30°C, more hot days and nights, and fewer cold days and nights.[12] Periods exceeding three consecutive days with temperatures at least 6°C above average have become significantly more frequent in the twenty-first century.[1] On July 17, 2019, Sodom reached 49.9°C, the highest recorded Israeli temperature since 1942.[1] A week-long May 2020 heatwave sometimes exceeded 40°C and was notable for its spring timing and sustained sequence of high temperatures rather than for breaking national records.[1]

In 2024, temperatures during the hot months averaged approximately 2°C above the historical average and surpassed the previous records associated with 2012 and 2023 by more than 0.5°C.[2] That winter also brought exceptional precipitation, including destructive hail and heavy rain in some places, while desert areas experienced one of their driest years on record.[2] Earlier extreme rainfall included December 2018 totals of 1.5–3 times the historical monthly average in some northern and central locations; one event delivered more than 200 millimeters and caused extensive flooding.[1] Three similar events in January 2020 resulted in several deaths.[1]

Israel’s mitigation framework developed through successive government decisions and international commitments.[13] Government Decision 542, adopted in September 2015, set per-capita greenhouse-gas targets of 8.8 metric tons of carbon-dioxide equivalent by 2025 and 7.7 by 2030.[13] Its 2030 sector targets included reducing electricity consumption by at least 17% and private-car mileage by at least 20% relative to business as usual, while generating at least 17% of electricity from renewable sources.[13] Achieving the emissions target was estimated to require a 24.5-million-ton reduction in 2030 relative to projected business-as-usual emissions.[13]

In April 2016, Government Decision 1403 established an implementation and energy-efficiency plan, with NIS 300 million allocated for an action plan during 2016–2019 and NIS 500 million in government guarantees for 2016–2025.[13] Israel signed the Paris Agreement on April 22, 2016, and issued its National Plan for Implementation that September, covering emissions reduction, monitoring, international financing, negotiations, and training.[13]

These measures followed a period in which total emissions and emissions intensity moved in different directions.[14] From 2000 to 2009, Israeli carbon-dioxide emissions increased approximately 11%, while per-capita emissions fell about 5% and emissions per unit of GDP fell about 18%.[14] Fuel-burning emissions in 2007 represented approximately 0.5% of the OECD total, although per-capita and GDP-unit emissions were high relative to OECD countries.[14]

In July 2021, the government announced targets of at least a 27% emissions reduction by 2030 and an 85% reduction by 2050 relative to 2015.[15] On October 24, 2021, the cabinet approved a climate-innovation and preparedness plan emphasizing emergency readiness, regional cooperation, technological development, and emissions cuts.[15] By the end of 2021, climate change had been recognized as a national-security threat; in early 2022, the National Security Council began incorporating a climate chapter into its annual strategic assessment and created a climate department head position.[16]

Financial regulation also developed: in December 2022, the Bank Supervisor required banks to disclose environmental-risk exposure, including climate risks, and its potential implications for business strategy.[17] Banks were also required to incorporate international climate agreements, including the Paris Agreement, into risk-management models.[17] Israel subsequently submitted its National Adaptation Plan to the UNFCCC in 2024.[3]

The National Action Plan for 2022–2026 contains 100 economy-wide and sectoral measures addressing mitigation, adaptation, finance, investment, and reporting.[1] Its adaptation measures include preparedness plans for ministries and local authorities, a climate-computing center, risk maps, urban shade, tree planting, urban forests, and nature-based management of urban runoff.[18] Other measures address stream restoration, flood prevention, fire buffers around communities, biodiversity restoration, disease monitoring, protection of high-risk health groups, and research into climate-resilient agriculture and food systems.[18]

Local adaptation includes urban shading and cooling, municipal preparedness plans, and reference scenarios for floods, fires, and extreme heat.[3] National work also encompasses sea-level modeling, climate-risk mapping, and a plan for fires in forests, woodlands, and open areas.[3] During 2022, funding initiatives addressed local authorities, shading, flood prevention, and green construction, while climate-crisis studies were planned for students from kindergarten through grade 12.[16]

Water management combines supply expansion with conservation and ecological considerations.[19] A water-system master plan approved in July 2011 was designed to function under uncertainty, including possible decreases in natural water sources; policy expanded to include conservation of landscapes and natural sources alongside desalination and agricultural wastewater reuse.[19] Freshwater’s share of total consumption declined from 92% in 1990 to approximately 75% in 2008 as wastewater reuse and desalination expanded.[14] These technologies are significant adaptation resources, and Israeli water reuse provides an example of water-infrastructure and efficiency measures applicable to regional water stress.[8]

Adaptation has also addressed Lake Kinneret, or the Sea of Galilee.[20] A 2019 study linked the lake’s contraction to changes in temperature, precipitation, watershed hydrology, and ecology, and discussed the government’s decision to build a northern Mediterranean desalination plant to supply water for replenishing the lake.[20] The proposal addressed the prospect of continued warming, greater evaporation, and reduced rainfall.[20] Earlier modeling for 2015–2034 estimated average available water in Kinneret at 14% below the observed 1979–2007 average and evaporation at 5% above it.[21] A 2026 projection placed the expected decline in Israel’s natural water supply by 2050 at approximately 15%, reflecting less rainfall, increased evaporation, and more frequent drought years rather than a projected equivalent reduction in household supply.[22]

Israel’s economy-wide mitigation targets are a 27% reduction in net greenhouse-gas emissions by 2030 relative to 2015, to no more than 58 million metric tons of carbon-dioxide equivalent, and an 85% reduction by 2050, to no more than 12 million tons.[1] A separately declared goal calls for net-zero greenhouse-gas emissions by 2050.[1] The 2021 sectoral program set a 2030 electricity-sector carbon-emissions reduction of 30% relative to its 2015 level of 37.6 million tons, and an energy-intensity target of 122 megawatt-hours per million NIS of GDP.[15] Manufacturing was assigned a greenhouse-gas reduction target of at least 30% from its 2015 level of 12 million tons.[15]

Waste-sector targets included cutting carbon emissions at least 47% from the 2015 level of 5.5 million tons by 2030 and reducing municipal waste sent to dumps by 71% from approximately 4.5 million tons in 2018.[15] For newly registered vehicles weighing up to 3.5 tons from 2030, the emissions target was 5% of the 2020 average for new vehicles in that category.[15] The program also specified environmentally friendly vehicles for all newly purchased city buses starting in 2026.[15] Longer-term 2050 sectoral targets included reductions of 85% in electricity-sector carbon emissions, 96% in transportation emissions, and 92% in municipal-waste emissions.[15]

The October 2021 implementation program included almost $230 million for energy efficiency in industry, commerce, and local government, together with cleaner transportation, public-transport electrification, removal of barriers to renewable infrastructure, and climate-tech innovation.[15] Multiple ministries were assigned funding responsibilities for measures including electric buses, charging stations, and industrial emissions reductions, while task forces were intended to address technology deployment and preparations for fires and floods.[15]

Israel’s climate-technology sector provides another dimension of its response.[15] A 2021 assessment counted nearly 1,200 companies established since 2000 that addressed climate challenges, including 235 clean-energy companies, 212 in climate-smart agriculture, 127 in sustainable mobility and transport, and 45 developing alternative proteins.[15] More than 560 private investment entities invested $2.97 billion in Israeli climate companies during 2018–2020, while government investment in climate start-ups totaled $280 million.[15]

Measured emissions show differing sectoral trajectories.[1] In 2022, total Israeli greenhouse-gas emissions were approximately 81.1 million tons of carbon-dioxide equivalent, 0.4% above 2015 and roughly 40% above 1996.[1] Fuel combustion accounted for 77.5% of emissions, including 45.2% attributed to combustion in energy sectors; waste treatment contributed 10.2% and fluorinated gases 6.2%.[1] Renewable sources supplied 10.4% of electricity consumption, while electricity-sector emissions were 9.5% below 2015 and transportation emissions were 9.4% above that baseline.[1]

Projected warming affects both average conditions and the frequency of dangerous heat.[3] The COP 30 factsheet projects an additional 1.5°C of warming during 2021–2050 on top of an existing 1.4°C rise, together with 12–20 additional days annually above 30°C, more than 20 additional nights above 20°C, and 13 fewer nights below 7°C.[3] It also projects more frequent drought in central and southern Israel during that period and a 10–24% precipitation decline by 2100, especially in the northeast.[3]

Earlier projections placed the 2021–2050 average temperature 1.5–1.8°C above the 1961–1990 average, with summer warming of 1.9–2.2°C compared with approximately 1.3°C in winter.[12] By 2050, those projections anticipated an additional 0.9°C under an optimistic emissions scenario or 1.2°C without emissions reductions, with 20 or 40 additional hot days on the coastal plain, respectively.[12] A business-as-usual projection using a 2020 baseline similarly estimated another 1.2°C by 2050, with summer temperatures potentially commonly exceeding 37°C and consequences for tourism, economic activity, cooling demand, and military equipment.[10]

High-emissions national reporting under SSP5-8.5 describes an expected average temperature increase of approximately 3.5°C relative to the preceding two decades, together with more heatwaves, floods, and torrential rain.[1] Its precipitation estimates include a 10–20% average decrease during 2017–2100 relative to 1988–2017 and, under a differently framed high-emissions assessment, a 20–25% decline in precipitation and rainy days.[1] Drying can contribute to desertification, loss of streams and wet habitats, drought, and water-source contamination.[1] The National Action Plan summarizes the principal trends as warming, drying, more extreme weather, and sea-level rise, with expected soil and vegetation dehydration and reduced natural flows.[18]

For the upper Jordan River basin, an ensemble of regional climate models combined with a daily hydrological model projected continued precipitation decline, greater potential evaporation, and reduced streamflow.[23] Changes in rainfall distribution and duration, together with falling soil moisture, were important mechanisms, with implications extending to neighboring countries.[23] A separate ensemble of decadal predictions for 2006–2036 projected increases of 0.51°C per decade in daily minimum temperature and 0.40°C in daily maximum temperature during the two decades following its initial simulated decade, but no significant precipitation change.[24]

Lower annual rainfall can coexist with more destructive short-duration downpours.[25] A study reported in 2021, examining conditions without declining greenhouse-gas emissions, projected approximately 30% fewer winter rainstorms, 25% less rainfall, and weaker winds in Israel and the eastern Mediterranean, alongside more intense rainfall bursts that could flood low-lying coastal areas.[25] Such events can damage bridges, dams, and roads and temporarily disconnect parts of the country.[10] Drainage and coastal-defense preparation are therefore relevant even under drying scenarios.[25]

A 2023 assessment found that 91% of Israel’s population had been exposed to hot days during 2018–2022 and placed Israel highest for drought risk among the countries examined.[26] Under a moderate emissions scenario, projected conditions in 2080–2099 included approximately 80 days annually above 35°C—about 45 more than the 1995–2014 average—and 145 nights above 20°C, about 48 more than that baseline.[26] A 2026 extreme-heat reference scenario described potential short-term temperatures of 45–47°C on the coastal plain and Shephelah and 50°C in the eastern valleys.[27]

Under the severe end-of-century scenario in that 2026 account, maximum temperatures could increase by 5–7°C from present levels, coastal heatwaves could reach 50.5–53°C, and coastal episodes of at least 45°C could recur every one to three years rather than approximately once a century.[27] Typical heatwaves could lengthen from about four days to approximately 18 days.[27] The same account placed 43% of recorded maximum-temperature records in 2010–2020 and another 42% in the preceding decade.[27]

Agricultural effects depend on crop, location, management, and emissions scenario.[28] Modeling of southern wheat and northern cotton for 2070–2100 found that wheat net revenues could become negative under a severe scenario; under a moderate scenario, outcomes ranged from a 43% decrease to a 35% increase depending on nitrogen application.[28] Cotton faced substantial yield reductions and economic losses under both scenarios.[28] Rainfall-event distribution influenced wheat yields, while additional irrigation and nitrogen reduced modeled losses and altered sowing dates did not.[28]

Livestock production is also exposed to humid heat.[29] Research using more than 320 million daily milk records from 130,000 Israeli cows over 12 years found that extreme humid heat could reduce milk production by as much as 10%, with effects lasting more than ten days.[29] Cooling systems reduced high-temperature losses by approximately 40% but did not eliminate them, and economic modeling indicated that cooling investments could pay off quickly without fully offsetting future heatwave losses.[29] A severe heatwave in the second half of August 2023 was associated with the deaths of more than 10,000 chickens in northern Israel.[1]

Health risks encompass heat emergencies and wider interactions among environmental conditions, infrastructure, and disease.[30] A 2025 public-health chapter projects approximately four degrees of warming by the end of the century and identifies possible pressures involving humidity, sea-level rise, disasters, flooding, water contamination, pandemics, forced migration, and border tensions.[30] Urban heat can intensify exposure: a 2019 account cited differences reaching 9°C between city centers and open areas, while a 2026 account described typical urban–surrounding differences of 3–4°C and occasionally more than 6°C.[31][27] Research on Israeli leishmaniasis incidence during 1956–2017 found no correlation with rising temperature or heat index and interpreted this as evidence of resilience associated with prevention measures.[11]

Woodland-fire risk may increase when winter rains arrive later, leaving abundant dry vegetation exposed during autumn.[7] Lower soil moisture, increased evaporation, and more frequent and intense heatwaves can increase fire frequency, intensity, and extent, threatening woodland ecosystems despite the fire resistance and regenerative capacity of many local species.[7] Population growth and development also fragment and contaminate forests, scrubland, freshwater systems, and coastal areas, weakening natural protection from extreme events.[19] Scenario-based ecosystem assessments identify additional threats from invasive species, floods, water loss, soil erosion, and fires.[19]

Coastal exposure combines rising seas with rainfall and drainage hazards.[1] National reporting records a Mediterranean sea-level increase of 14.9 centimeters over its 19-year observational period and a temporary adaptation-planning scenario of 1.06 meters above the national baseline by 2100.[1] Potential consequences include coastal flooding, damage to shorelines and cliffs, harm to infrastructure and tourism, and inland movement of the saltwater–freshwater interface that could complicate groundwater extraction.[1]

A 2024 planning assessment identified the Kishon basin in Haifa Bay and low-lying areas near the Ayalon and Yarkon rivers, including parts of Tel Aviv, as exposed to combinations of extreme rain and rising seas.[32] It highlighted heat increases around the Arava, Golan Heights, and Tiberias, possible crop changes in the Upper Galilee, and desertification risks for farmland and forest near Beersheba.[32] Past Ayalon floods in 1991–1992 and 2013 and Kishon–Gadora flooding in 1991–1992 informed this planning context.[32] Proposed development under Bay Gateway, or TAMA 75, involving more than 100,000 housing units near Haifa Bay’s Bazan refineries site, was identified as requiring attention to these hazards.[32]

Electricity systems face simultaneous increases in demand and reductions in operating efficiency during prolonged heatwaves.[2] Heat can reduce power-plant and grid performance while raising air-conditioning demand, increasing the risk of shortages and failures.[2] Reported 2025 incidents included electricity and air-conditioning failures at Sayarim Base during extreme heat, and high-voltage line trips during a May heatwave and fires around the Galilee and Beit Shemesh that interrupted supply to thousands.[2] Other reported heat impacts include slower train services and electricity disruptions.[27]

Military infrastructure and operations face flooding, heat exposure, and technical constraints.[33] Flooding at Hatzor Air Force Base in January 2020 heavily damaged F-16 aircraft, illustrating infrastructure vulnerability to extreme rain.[33] High temperatures can reduce air density and affect aircraft takeoff, endanger troops, restrict training opportunities, and potentially overheat cooling systems on military platforms.[33][10] Defense preparations have included a climate threat scenario, a strategic roadmap, vulnerability surveys of bases and installations, and discussions with international partners.[16]

Regional security assessments also identify heat, water and food shortages, and sea-level rise as potential threat multipliers interacting with socioeconomic and governance problems.[33] The Syrian drought of 2006–2011 provides an example in which agricultural failure and economic deterioration were followed by rural-to-urban migration and heightened tensions.[33] Regional instability and migration are therefore among the possible indirect implications considered in Israel’s climate-security planning.[33]

The adequacy of implementation has been a significant policy concern.[34] A 2022 review reported that 84% of public bodies examined by the State Comptroller lacked a climate-crisis coping plan, while only 16% of 278 tasks in a government adaptation decision appeared in ministerial work plans.[34] The administration established after the 2018 adaptation resolution initially had neither budget nor personnel, and the July 2021 low-carbon resolution had no implementation budget when approved.[12][35] A 2024 review found that most of more than 100 proposed emissions-reduction measures lacked discernible implementation or budget allocation and reported that existing measures left Israel off track for its targets.[36]

Legal commitments, announced goals, and implemented measures have not always aligned.[36] The July 2021 resolution did not itself commit Israel to net zero; a later declaration added that ambition.[35][1] The climate bill passed its first reading in 2022, but a 2024 review reported that it had not received final Knesset approval and that Israel had no explicit carbon tax.[16][36] A separate 2024 assessment found no national climate strategy, specific expectations for private-sector contributions, or binding policies implementing the 2050 net-zero announcement.[17] These findings describe their respective reporting dates rather than establishing subsequent legal status.[17][36]

In a July 2026 interview, former senior Environmental Protection Ministry official Gil Proaktor characterized Israel as unprepared and said it lacked an approved, funded national adaptation plan and a climate law obligating ministries to prepare plans.[37] He warned about rail and electricity vulnerabilities, citing a 10–15% loss of available gas-fired generation output during extreme heat and describing the region as warming approximately 20% faster than the global average.[37] The interview’s criticism concerned domestic approval, funding, and legal duties; the 2024 factsheet separately records submission of a National Adaptation Plan to the UNFCCC.[3][37]

Scientific comparisons also require care: projections use different baselines, emissions pathways, periods, and geographic scales, and do not constitute a single interchangeable forecast.[1][24] Earlier water-sector research found no clear nationwide precipitation trend, while later reporting identified declines over specified periods; model results also differ between nationwide decadal ensembles and the upper Jordan basin.[21][23] Regional modeling is constrained by limited data and difficulties translating global models to local conditions.[8] Flood examples demonstrate vulnerability rather than proving climate attribution for individual events, and climate stress should not be treated as the sole explanation of the Syrian civil war.[33]
