Part I — Situation overview

On the last weekend of June 2026, HungaroMet (the national meteorological service) raised the heat warning to the highest, third degree, with a red warning in several regions; in the hottest hours values between 36 and 41 degrees are expected, in Budakalász 40.7 degrees were measured on Saturday, and across most of the country there were tropical nights — not cooling below 20 degrees (MIAK press monitor, 29 June 2026 — Portfolio, 24.hu, Mandiner). The load is systemic, and the effects have already reached critical infrastructure: because of the warming of the Danube, which serves as cooling water, on Saturday the electrical output of the Paks reactors had to be cut back by 240 megawatts (MW) and on Sunday by about 320 MW; MAVIR (the Hungarian electricity system operator) expected a peak load of roughly 7300 MW for Monday, about 90 percent of the summer maximum. According to MÁV the five-day average rail temperature approached 54 degrees, in places reaching 56, so speed restrictions were introduced on several lines; the water level of Lake Velence at Agárd fell to 47 centimetres against the 130-centimetre optimum, a historic low; and in more than fifty municipalities of Pest county water consumption was restricted.

In recent days the government has rolled out response measures one after another. Prime Minister Péter Magyar announced that, because of the Monday peak of the heat, home working would be ordered in the public sector and every employer would be asked to do the same; the cabinet earmarked HUF 3.6 billion with immediate effect for the refurbishment of hospital and outpatient-clinic air-conditioning equipment, and held out the prospect of a comprehensive 2027–2029 cooling-reconstruction programme as well. The Defence Forces prepared more than twenty-five thousand sachets of drinking water for major events, and bottled water is being distributed at stations. Meanwhile, according to a communication from the World Health Organization (WHO), the early-summer heatwave has already caused more than 1300 excess deaths in Europe — the organisation warned that the continent is warming at twice the global average, and that previously rare heatwaves are becoming ever more frequent.

According to MIAK’s reading these steps are right and necessary, but reactive in character: ad hoc responses to a crisis already under way. Heat, however, is not an exceptional event but the predictable, every-summer test of climate adaptation. The difference is not rhetorical: refurbishing hospital cooling in an emergency costs three times as much and is worth half as much as in a pre-scheduled maintenance programme. The real yardstick is therefore not whether the government reacts to the red alert, but whether it builds, out of the ad hoc firefighting, a planned, accountable adaptation system.

Part II — Literature foundation

Before turning to MIAK’s concrete proposals, it is worth fixing the scientific frame within which the state heat response can be assessed. The influential report of the British economist Nicholas Stern, The Economics of Climate Change — The Stern Review, establishes the thesis that adaptation is unavoidable and economically rational: deferring preparation is dangerous and far more expensive than the preparation itself — this is exactly the stake of the difference between a reactive and a planned response. The American economist William Nordhaus (one of the founders of climate economics, 2018 laureate of the Nobel Memorial Prize in economics) models, in his work Warming the World, the relationship between temperature and economic damage — the “damage function”, that is, the temperature–damage function — and in the newer estimates this curve is more pessimistic than in the earlier models; this gives the conceptual basis of the domestic DICE-MAGYAR climate-economics model (K9), which also builds in heatwave health and water-management damage. The Canadian author Naomi Klein’s volume On Fire frames heat as a systemic crisis and stresses that the burden falls on the most vulnerable — therefore the yardstick of state crisis management is precisely whether it reaches the elderly, the sick and outdoor workers. The detailed literature treatment — by author, with quotations — can be found in section 6.4 Literature in detail.

Part III — MIAK’s concrete proposal

MIAK proposes three measurable measures that turn state action against heat from ad hoc crisis management into a planned, accountable adaptation programme.

3.1 A cross-sectoral, quantified heat-alert protocol (by the next summer season)

The current steps — home office, drinking-water distribution, speed restrictions — are individually reasonable, but ad hoc decisions, not elements of a pre-set system. MIAK proposes that every level of the heat alert should carry a mandatory, quantified and cross-sectoral action package: a health and ambulance-service capacity reserve, school and workplace working-time rules, a transport protocol (speed limits, replacement water), and the active reaching of vulnerable groups — telephone and on-site checks of the elderly and the chronically ill. The basis of the protocol should be a public, real-time data interface that links the level of the heat alert to the health-load and system-load data. This builds on the logic of E4 (the prevention data programme): preparation is thus measurable and auditable after the fact, not dependent on local improvisation. The difference from current practice is that the prime-ministerial announcement is replaced by a pre-published, predictable set of rules — the citizen, the hospital and the employer know in advance what happens at a red alert.

3.2 Making hospital and track infrastructure heat-resistant (a multi-year, scheduled programme)

The HUF 3.6 billion hospital cooling refurbishment is welcome, but a point-like decision taken in a crisis — it shows precisely that maintenance has so far been neglected. MIAK proposes that this should not be a one-off firefighting exercise but the first step of a multi-year, scheduled heat-resistance programme: the planned, budgetarily pre-fixed development of inpatient-care institutions’ cooling, of passive cooling within the framework of K6 (the building-energy-efficiency programme — shading, insulation, green façades), and of the heat-resistance of the railway track. The rail-temperature slowdowns and the Paks throttling are two sides of the same problem: critical infrastructure must be sized not to current but to the heat expected ten years from now. Railway heat-resistance is an adaptation dimension missing today — MIAK would extend the KO4 (data-based-priority railway development) programme point with this aspect.

3.3 Energy resilience and targeted compensation for the heat peak

The forced throttling of the Paks reactors and the 90-percent system load showed the heat sensitivity of the energy system: precisely at the time of the greatest cooling demand the supply side narrows. According to MIAK’s K2 (energy-transition plan) and K7 (energy-market shock resilience) programme points, the solution is the expansion of storage capacity and a diversified source mix, so that peak load does not lead to a supply risk — the heat-dependence of a single large plant should not be able to decide the stability of the system. And if sustained heat drives up energy prices, the burden hits the poorest households hardest; for these cases MIAK proposes targeted, income-proportionate and time-limited compensation — not a general, universal price cap that distorts consumption and subsidises the better-off as well.

These three proposals are bound together by a single principle: heat is a predictable, recurring risk that must be answered with a planned, measurable and targeted system — by Stern’s logic (see 6.4.1) deferring adaptation is the most expensive scenario, because the damage accumulates with compound interest.

Part IV — Expected impacts and risks

Dimension Expected impact Risk
Healthcare Active reaching and heat-resistant hospitals can reduce heat-related excess mortality If the protocol stays formal, the most needy (lone elderly) are left out
Energy and infrastructure Storage expansion and a heat-resistant track stabilise the peak load and transport The investment requires upfront public spending; its benefit appears in the future, at an uncertain time of heat
Economy and society Targeted compensation protects the poorest from the energy-price shock With poor targeting the support leaks away; with a general price cap it burdens the budget

The main consideration is timing and targeting. The adaptation investment — hospital cooling, storage capacity, heat-resistant track — costs money now, while its benefit appears at the next heatwave, so the political logic always pulls towards deferral. The proposal tips to the risk side if crisis management stays permanently ad hoc: then every summer one has to reach again for the emergency, more expensive solution. The proposal works, however, if the current decisions — hospital cooling, home office, drinking-water distribution — become the first, built-in elements of a pre-published protocol and a multi-year programme, rather than improvisation repeated year after year.

Part V — Measurability and summary

5.1 What is worth tracking? (suggested KPIs)

A few suggested performance indicators (KPIs, in English: Key Performance Indicator) from which it will be visible in 12–24 months whether the direction is good:

  • Whether the cross-sectoral, quantified heat-alert protocol is ready for the next summer season.
  • Whether heat-related excess mortality falls among the vulnerable groups (the elderly, the chronically ill).
  • Whether the hospital cooling refurbishment continues with the scheduled, accountable steps of the announced 2027–2029 programme.
  • Whether energy-storage capacity expands so that the heat peak (≈7300 MW) is covered with a reserve.
  • Whether the number of line sections affected by heat-related railway speed restrictions falls as a result of the heat-resistant development of the track.

5.2 Summary

MIAK’s message to decision-makers and the public alike: the current steps of state action against heat are right, but the real task is to turn reactive crisis management into planned adaptation. MIAK asks the government to lift the ad hoc decisions taken in response to the red alert into a pre-published, cross-sectoral heat-alert protocol, to make the heat-resistance of hospital and track infrastructure a multi-year programme, and to strengthen the reserves of the energy system. This approach moves two MIAK foundational values: data-drivenness — because the effectiveness of heat protection is decided by measurement, not improvisation — and universal representation — because the burden of heat falls on the most exposed (the elderly, the sick, outdoor workers), and targeted protection is precisely their representation in the climate crisis. The two here are not abstract labels: in the days of the red alert human lives and livelihoods depend on them.

Part VI — Justifications and further sources

6.1 Press framing by spectrum

The topic mobilised the whole spectrum, with differing emphases. The economic-professional band (Portfolio) highlighted the fact of the warning and the near-record values, as well as the load on the energy system. The liberal-left and public-affairs band (Telex, 24.hu, 444.hu) focused on the state response measures and the concrete consequences: public-sector home working, the Paks throttling, the delays caused by rail temperature, and the receding of Lake Velence. The WHO’s figure of 1300 European excess deaths was brought by Telex, placing the domestic heat in a wider, continental frame. The conservative band (Magyar Nemzet, Mandiner) discussed primarily the water restriction and the weather forecast (the approaching cold front), in a less policy-oriented frame; Mandiner, however, citing a climate researcher, also presented the cooling and shading role of urban trees. Looking at the spectrum as a whole, it is striking that the systemic interpretation of heat — the distinction between reactive crisis management and planned adaptation — appeared in few places: the dominant framing was the acute event and the state response, not the question of structural preparation.

6.3 Policy aspects

  • Environment and climate (programme points) — the energy transition and storage capacity (K2), energy-market shock resilience (K7), building energy efficiency and passive cooling (K6) and the domestic integrated climate-economics model (K9) provide the framework of adaptation;
  • Healthcare (background material) — the prevention data programme (E4) is the tool of heat protection for vulnerable groups;
  • Transport and infrastructure (programme points) — the data-based priority of railway development (KO4) is to be extended with the dimension of heat-resistant track infrastructure.

6.4 Literature in detail

6.4.1 Nicholas Stern: The Economics of Climate Change — The Stern Review

The central thesis of Nicholas Stern’s report is that adaptation is not an option but a necessity, and deferring it is more expensive than preparation. The direct effects of climate change can no longer be prevented, but societies and economies can be protected — through better planning and more resilient infrastructure.

„The costs of stabilising the climate are significant but manageable; delay would be dangerous and much more costly."

In the case of the Hungarian heat crisis this means that the development of hospital cooling and the heat-resistant track is not a cost but the avoidance of deferred, compounding damage — this is the logic carried forward by MIAK’s K7 programme point, which replaces ad hoc firefighting with planned resilience.

6.4.2 William Nordhaus: Warming the World

William Nordhaus examines the economic effects of climate in an integrated model — the DICE model (the coupled, dynamic model of climate and the economy) — centred on the temperature–damage function. An important lesson of his work is that the newer estimates are more pessimistic than the earlier ones: the market, non-market and potentially catastrophic effects together indicate more severe damage.

„The resulting temperature damage function is more pessimistic than that of the original DICE model."

The domestic application is the K9 DICE-MAGYAR programme point: if the model also builds in the heatwave health load and the water-management damage, then the return on hospital cooling or storage expansion can be quantified — and the investment decision can be made on the basis of data, not political sentiment.

6.4.3 Naomi Klein: On Fire — The Burning Case for a Green New Deal

Naomi Klein interprets the record heat as a systemic crisis, not an isolated event, and stresses that the burden falls most heavily on the least guilty and the most vulnerable.

„…if we are going to avoid a future marked by more brutal scapegoating of the most vulnerable and blameless, we will need to find the fortitude to go head-to-head with the powerful players that bear the greatest responsibility for the climate crisis."

This framing is directly operational in Hungarian crisis management: the yardstick of state action is whether it reaches the most exposed. Public-sector home working, hospital cooling and station drinking-water distribution are a good direction if they serve specifically the protection of the elderly, the sick and outdoor workers — this is what MIAK’s E4 proposal puts at its centre with active reaching.

6.5 International comparison

For quantified heat protection the French heat plan (Plan Canicule) is the reference: after the 2003 European heatwave, which claimed several tens of thousands of lives, France built a level-based, mandatory action protocol that links the weather warning to health and municipal measures and keeps a register of vulnerable residents. This is exactly the type of pre-published system that the 3.1 proposal finds lacking in domestic practice. On the energy side, the southern-European and Californian experience shows that the heat peak can be managed safely only with as much storage capacity and demand-side flexibility as can bridge the heat-induced fall in generation (as in the Paks example). Both patterns can be built into the Hungarian adaptation programme — as a concrete, accountable commitment, not as a general principle.
