Part I — Situation overview

In the summer of 2026, several faces of the Hungarian climate crisis condensed within the span of a few days. According to data from HungaroMet (the national meteorological service operating as the legal successor of the former National Meteorological Service, OMSZ), 42 degrees Celsius was measured in Szécsény — the hottest temperature ever recorded in Hungary. According to Portfolio’s map analysis published on 6 July 2026, more than 100 millimetres of moisture is missing from the top one-metre soil layer relative to saturation over almost the entire country, which under average weather would be typical only by the end of August; in the central part of the country the precipitation total of the past thirty days did not reach even 15 millimetres in places. A day later Portfolio published county-level data on the mortality impact of heatwaves: the analysis by Szabó Péter and Pongrácz Rita, based on data of the Central Statistical Office (KSH) and the National Health Insurance Fund (NEAK) for 2015–2025, found that during intense heatwaves excess mortality reached 35 per cent in Tolna county, 28 in Baranya, 26 in Jász-Nagykun-Szolnok and 25 in Bács-Kiskun. Meanwhile the water disappeared within weeks from a small watercourse near Sátoraljaújhely, the Ronyva stream, causing mass ecosystem die-off.

The topic is not without precedent, but now it converges along several threads. Researchers state with 90 per cent certainty that the increasing frequency of heatwaves is not natural variability but a consequence of human activity — second- and third-degree heat alerts (warnings tied to a daily mean-temperature threshold, ordering health-system preparedness), which were unknown in the seventies and eighties, are now regular. The heat is not a Hungarian peculiarity: according to Telex’s report, in Southern Europe — Portugal, Spain, France and Greece — a total of some 20 thousand hectares of land burned, 13 thousand hectares in Portugal alone. And according to ATV’s news, Hungary may have a new climate law as early as this year. The phenomenon is thus at once a public-health, an agricultural and a climate-policy matter — and it is dangerous precisely because the individual ministries handle it separately.

By MIAK’s reading, the real stake of the news is not a single record or a single dried-out stream, but the structural absence of preparedness. It is telling that — as the researchers point out — excess mortality is not highest in the hottest counties: Csongrád-Csanád is the country’s warmest county, yet its mortality excess is lower, connected with the country’s highest share of air-conditioned homes and better adaptation. Death is thus a function not merely of temperature but of preparedness — in other words, it can be influenced with public-policy tools. The character of the problem is therefore not that of the weather, but of the missing, integrated adaptation system.

Part II — Literature foundation

Before turning to MIAK’s proposals, it is worth fixing the economic frame. According to the 2007 report of Nicholas Stern (British economist, author of the world-famous Stern Review, former chief economist of the World Bank), climate change is “the greatest market failure the world has ever seen”, and its main lesson for the present situation is that adaptation — defence against the impacts — is no longer a choice but a necessity: the warming of the coming decades cannot be prevented, only the damage can be moderated with better planning, more resilient infrastructure and drought-tolerant crops. By Stern’s calculation the annual cost of action is roughly 1 per cent of GDP, while that of inaction is a multiple of it — this ratio gives the economic justification of MIAK’s adaptation spending. The climate damage function of William Nordhaus (American economist, Nobel memorial laureate, one of the founders of climate economics, author of the DICE/RICE model family) complements this: it quantifies the agricultural, health and water-management damage of warming as a function of temperature rise, and points out that the estimates which also build in adaptation are less pessimistic — that is, every forint invested in preparedness measurably reduces the damage. The detailed literature treatment — by author, with source references — can be found in the 6.4 Literature in detail section.

Part III — MIAK’s concrete proposal

MIAK proposes three measurable measures which, instead of fragmented, case-by-case response management, weave water management, public health and agriculture into an integrated, accountable adaptation system.

3.1 A national water-retention and drought-adaptation programme (launch from the next budget year)

The first and cheapest defence is keeping the water where it falls. MIAK proposes launching a national water-retention programme which keeps precipitation in the landscape instead of fast run-off: restoration of small watercourses and reservoirs, channel reconstruction, inland-water retention, soil-moisture-based irrigation optimisation. The core of the programme is the water-catchment community channel of the MG5 community resource-management framework, which prescribes a local water-allocation plan and drought protocol built on Elinor Ostrom’s principles of community self-governance in the pilot regions; this is complemented by the soil-sensor network of the MG1 precision agriculture programme, which makes irrigation targeted with real-time soil-moisture data. The drying-out of the Ronyva stream and the end-of-summer-level soil dryness show precisely that water-stock management cannot wait until the next drought. In Stern’s argument (see 6.4.1) this is classic adaptation: a relatively cheap advance investment that prevents later damage orders of magnitude larger.

3.2 A heat-alert-based public-health protocol (drawn up within 6 months, first live season next summer)

The second proposal targets excess mortality directly. MIAK asks for a uniform, pre-announced heat-alert-based public-health protocol (heat-health action plan) which assigns automatic, accountable measures to HungaroMet’s graded alerts: targeted outreach to the most vulnerable (the elderly, the chronically ill, small children, people living in poorly cooling homes), cooled community spaces, reinforced ambulance and primary-care capacity, and long-term heat-stress reduction built into urban planning (shading, green surfaces, moderating the urban heat-island effect). The key to the protocol is the county-level, weekly-resolution data: the Szabó–Pongrácz analysis proves precisely that preparedness — for example the availability of air conditioning — meaningfully reduces mortality, so the impact of the measure is measurable. The professional basis of the system can be provided by the K9 domestic integrated climate-economics model, which also prices in the health burden of heatwaves. An important point of legal precision: the alert is issued by the meteorological service, but implementation is the coordinated responsibility of the health, social and municipal actors — the protocol fixes precisely this allocation of responsibility in advance.

3.3 Drought-damage insurance and an accountable climate law (simultaneously with the adoption of the climate law)

The third proposal looks to the future and to the legal framework. Farmers need a working, predictable drought-damage insurance system which shares the financial risk of blows like the current dryness — which causes forced ripening and low average yields — among the state, the insurance sector and producers, avoiding every drought ending in one-off, unpredictable damage relief. To this is joined the substantive requirement for the climate law now in preparation: according to MIAK, the law is worth something only if it fixes not general principles but binding, date-bound adaptation targets accountable year by year — in the logic of the K1 measurable climate targets, which prescribes a sector-by-sector annual report submitted to the National Assembly and a correction obligation. Nordhaus’s climate damage function (see 6.4.2) is the yardstick here: the targets must be calibrated to the expected agricultural and health damage, not to a politically comfortable level.

These three proposals are bound together by a single principle: adaptation is not firefighting handled separately by each ministry, but an integrated, data-driven, accountable system in which the protection of water, health and agriculture is connected in a single plan, with measurable targets. The climate law will be more than a symbolic gesture if it also creates this structure.

Part IV — Expected impacts and risks

Dimension Expected impact Risk
Public health Decreasing heatwave excess mortality; targeted protection for the most vulnerable; measurable, county-level preparedness If the protocol exists only on paper and there is no capacity behind it (ambulances, cooled spaces), the impact fails to appear; reaching the poorest, living in poorly cooling homes, is the hardest
Agriculture More predictable farming; water retention and precision irrigation moderate drought damage; working risk-sharing A badly designed drought-damage insurance may cause moral hazard (excessive claims) or unaffordable premiums; water retention is investment- and time-intensive
Climate policy / budget Accountable, date-bound adaptation targets; enforcing the Stern logic of “cheaper to prevent than to pay” Adaptation is a budget item in the short run, its return delayed; the targets may be diluted if the climate law gives only a framework of principles, without accountable milestones

The main question to weigh is timing and financing. The cost of adaptation — by Stern’s estimate a band around 1 per cent of GDP in order of magnitude — arises in the present, while its benefit (avoided mortality, saved harvests, averted disaster damage) is delayed and harder to see, which makes defending the expenditure politically harder. The proposal works if water retention is paired with real infrastructure, the heat protocol with real capacity, and the insurance with a sustainable premium structure. Otherwise there is a danger that the spectacular adoption of the climate law hides the response management left unchanged and fragmented — or, conversely, that a rushed, under-planned insurance or water-management construction becomes more expensive than a disciplined, data-based build-up.

Part V — Measurability and summary

5.1 What is worth tracking? (suggested KPIs)

The success of the proposal is worth tracking on the basis of a few suggested performance indicators (KPIs, in English: Key Performance Indicator — indicators that show whether it succeeded):

  • the trend of county-level, weekly-resolution heatwave excess mortality in the coming seasons (suggested target: a meaningful, documented decrease in the most affected counties);
  • the number of binding, date-bound adaptation targets included in the climate law and their annual fulfilment rate;
  • the number of water-catchment regions covered by the water-retention programme, and the evolution of the soil-moisture deficit in the areas concerned;
  • the share of arable land covered by drought-damage insurance (suggested target: a meaningful, documented increase).

5.2 Summary

MIAK’s key message: this summer is not an extraordinary episode but a portent of the new normal — and heat-induced mortality, as well as drought damage, is not a stroke of fate but can be meaningfully reduced with preparedness. MIAK asks decision-makers to write binding, accountable adaptation targets into the climate law now in preparation, to launch a national water-retention programme, to draw up a uniform heat-alert-based public-health protocol, and to create working drought-damage insurance — in a single, integrated plan. Two MIAK foundational values move together here: data-drivenness, because the county-level mortality and soil-moisture data show precisely where and in what it is worth investing; and universal representation, because heat and drought hit the most vulnerable — the elderly, the sick, small farmers — the hardest, and their protection is a community responsibility, not a matter of individual luck.

Part VI — Justifications and further sources

6.1 Press framing by spectrum

The economic band (Portfolio) put the emphasis on the data and the maps: it published the county-level excess-mortality and soil-moisture analyses with scholarly source references, highlighting the public-policy lesson of preparedness — this band framed the topic not as drama but as measurable risk. The public-affairs television band (ATV) brought the topic on two separate threads: on the one hand the concrete, shocking case of the drying Ronyva stream, on the other the legislative news of the coming climate law — that is, the parallel framing of the problem and a possible answer. The liberal-left public-affairs band (Telex, HVG) highlighted the international and the consumer-utility dimension: Telex the Southern European wildfires, and HVG’s weekly round-up how much waste the suppressed utility prices have habituated us to, and that the drought is bad news for agriculture. Népszava carried the topic at title level (title-level reference only). The framings thus differ along the data, the concrete case, the legislation and the consumer dimension; MIAK’s ideology-free reading traces all of this back to a single question — measurable adaptation preparedness.

6.2 Facts and data

  • 42 degrees Celsius was measured in Szécsény — the hottest temperature ever recorded in Hungary (HungaroMet; Portfolio, HVG, July 2026).
  • More than 100 millimetres of moisture is missing from the top one-metre soil layer relative to saturation over almost the entire country; soil moisture does not reach even 30 per cent of the usable water stock over most of the country (HungaroMet; Portfolio, 6 July 2026).
  • In the central part of the country the precipitation total of the past thirty days did not reach even 15 millimetres in places (HungaroMet; Portfolio, 6 July 2026).
  • Excess mortality measured during intense heatwaves (2015–2025, KSH and NEAK data): Tolna 35%, Baranya 28%, Jász-Nagykun-Szolnok 26%, Bács-Kiskun 25%, Budapest and Békés around 24% (analysis by Szabó Péter and Pongrácz Rita; Portfolio, 7 July 2026).
  • During the July 2024 heatwave in Budapest, the two-week hot period brought 34 per cent excess mortality compared with that year’s May–September average (Portfolio, 7 July 2026).
  • It can be stated with 90 per cent certainty that the increasing frequency of heatwaves is a consequence of human activity, not natural variability (Szabó–Pongrácz analysis; Portfolio).
  • The water disappeared within weeks from the lower reach of the Ronyva stream (a tributary of the Bodrog, near Sátoraljaújhely), causing mass ecosystem die-off (ATV, 7 July 2026).
  • In Southern Europe (Portugal, Spain, France, Greece) a total of some 20 thousand hectares burned; 13 thousand hectares in Portugal alone between Thursday and Sunday (the Guardian via Telex, 6 July 2026).

6.3 Policy aspects

  • Environment and climate (programme points) — the gravitational centre of the topic: measurable, accountable climate targets, climate-economics damage estimation and water retention as the primary adaptation tool;
  • Agriculture (programme points) — the defence against drought: community water management, precision irrigation optimisation and farmers’ risk-sharing through drought-damage insurance;
  • Environment and climate (background material) — the framework for integrated climate-economics modelling of the heatwave health burden and water-management costs.

6.4 Literature in detail

6.4.1 Nicholas Stern: The Economics of Climate Change (Stern Review)

The central claim of the Stern Review is that climate change is the greatest market failure ever seen, because emitters do not bear the full social cost of the damage they cause. For the present topic the work’s most important lesson is the necessity of adaptation: Stern records that the warming of the next two to three decades can no longer be prevented, so the emphasis is on defence — better information, planning, more resilient infrastructure and more drought-tolerant crops. The work separately highlights the growth of heatwave risk: by model calculation, the temperature level of the 2003 European heatwave — Europe’s hottest summer in 500 years — could become an average summer by 2050, and the risk is greatest in cities because of the heat-island effect. By Stern’s cost argument, the annual price of action is roughly 1 per cent of GDP, that of inaction a multiple of it. Translated to the Hungarian drought and heatwave mortality: water retention and the heat protocol are exactly the cheap, advance adaptation which by the Stern logic pays back many times over.

6.4.2 William Nordhaus: Warming the World

Nordhaus is one of the founders of climate economics; the DICE/RICE model family captures the economic impact of warming in a single optimisation framework. The work’s key concept is the climate damage function: it estimates agricultural, health and other damage as a function of temperature rise, in regional breakdown. Nordhaus points out that agriculture and health are the sectors where damage estimation is the most advanced, and that the newer estimates which also take adaptation into account are less pessimistic than the early, adaptation-free models — that is, preparedness has a measurable damage-reducing effect. Applied to the Hungarian situation: the low average yields and the heatwave excess mortality experienced now are exactly the damages which the damage function quantifies, and whose pricing-in can give the economic yardstick of the climate law’s adaptation targets — this is what the domestic integrated climate-economics model would serve.

6.5 International comparison

The proven international tool of defence against heatwave mortality is the heat-alert-based public-health action plan (heat-health action plan). In France, a country-wide system was built after the roughly 15 thousand excess deaths of the 2003 heatwave (Plan National Canicule): graded alerts, a register of vulnerable persons and their targeted outreach, cooled spaces — the mortality of the following great heatwaves became perceptibly lower. In Spain, similar regional-level heat plans operate, as part of urban shading and green-surface development. In water retention, Spanish and French agriculture has moved towards soil-moisture-based, precision irrigation to use the scarce water stock in a more targeted way. According to the climate indicators of the European Environment Agency (EEA — the EU’s environmental data and assessment body), the Southern European drought and fire season is getting ever longer — the current 20-thousand-hectare Southern European wildfire wave is part of this. The lesson chimes with MIAK’s proposals: it is not the heat or the drought in itself, but the absence of institutionalised, pre-announced preparedness that causes the avoidable damage.
