Part I — Situation overview

In the last days of June 2026 a heat dome — a high-pressure atmospheric system settling over the region, sinking and warming the air — settled over Hungary. According to the forecasts, from Monday and Tuesday it could reach as much as 42 degrees over a significant part of the Great Plain, which could break the absolute Hungarian heat record of 41.9 degrees measured on 20 July 2007 at Kiskunhalas; the same anticyclone had already caused values above 44 degrees in France before drifting over Hungary (MIAK press monitor, 27 June 2026 — Portfolio, 444.hu, Telex). The load is system-level: MVM has asked consumers for evening thrift, the use of cooling air conditioners has quintupled in two weeks, and several settlements in Pest county have introduced water restrictions. A cold front may bring relief only on Wednesday, but even then only up to a peak around 30 degrees.

The topic is more than a one-off weather colour piece because extreme heat strains three systems at once. The energy system is stretched by the cooling peak demand — the most electricity is needed precisely when, because of the heat, production too is more vulnerable. Water management is strained by drought and surging consumption. And the health system is strained by heatstroke as well as the cardiovascular burden, which disproportionately afflicts vulnerable groups — the elderly, the chronically ill, outdoor workers. According to a study published in the journal Global Environmental Change, processing EU data from 2004 to 2022, extreme heat reduced average household income across Europe by some 3 percent, and pushed a further 5.6 million people into the risk of poverty; the poorest fifth suffers the greatest loss, because it works in a larger proportion in sectors exposed to the heat.

MIAK’s reading is that heat is not an exceptional event, but a regularly recurring test of climate adaptation. The proper response is not the one-off alert, but a pre-fixed, numerical protocol that links the peak management of the energy system, water management and health preparedness. The failure of adaptation is not a “saving”, but a deferred, compounding cost — the later we act, the more expensive the catch-up will be.

Part II — Literature foundation

Before turning to MIAK’s concrete proposals, it is worth fixing the scientific frame. 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: delaying preparation is many times more expensive than preparation itself. The WHO (World Health Organization) report European Health Report 2024 documents the health side of heat: it calls for special attention to the protection of children, the elderly and the low-income, because the burdens of climate change fall on them most severely, while the health systems struggle with labour shortages. And the volume On Fire by the Canadian author Naomi Klein frames heat and disaster as a system-level crisis: record temperatures (in her book the example is the 49.5-degree record of Port Augusta in South Australia in 2019) are not isolated anomalies, but symptoms of a “climate emergency” that demands a social and economic response. 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 heat from a one-off alert into a planned, accountable adaptation programme.

3.1 A numerical, unified heat-alert protocol (by the next summer season)

The current heat-alert system is a threshold-based alert, but behind it there is no cross-sectoral, mandatory action plan. Building on the logic of the E4 (prevention data programme), MIAK proposes that every level of the heat alert have a pre-fixed, numerical package of measures: hospital and ambulance-service capacity reserve, modification of school and workplace schedules, and the active reaching of vulnerable groups (telephone and on-site checks for 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 with health-load data — so that preparation is measurable and auditable after the fact, not dependent on local improvisation.

3.2 Energy resilience: storage capacity and peak management

Extreme heat exposes the bottleneck of the energy system: the gap between the early-evening cooling peak and the evening fall-off of solar energy (which the literature knows as the “duck curve”) cannot be managed without storage. According to MIAK’s K2 (energy transition plan) programme point, Hungary’s current storage capacity of roughly 50 MW is a fraction of what is needed; the goal is an annual storage expansion of 200–500 MW, capable of covering the heat peak as well. Connected to this is K7 (energy-market shock resilience): a strategic energy reserve and a diversified source mix, so that peak load does not lead to a supply risk. MVM’s current request for evening thrift signals that this is not a theoretical question — storage is one concrete, investable element of adapting to heat.

3.3 Targeted, automatic compensation in case of an energy-price shock

If persistent heat and surging cooling demand push up energy prices, the burden hits the poorest households hardest — precisely those who, according to the study, also suffer the income-reducing effect of heat most. MIAK’s G25 (energy-price-shock preparedness plan) programme point therefore proposes automatic, income-proportional and targeted compensation — not a general, all-encompassing price cap, which distorts consumption and also subsidises the better-off. Targeting is the key: the support should go where heat and price together pose a real risk to livelihood.

These three proposals are bound together by a single principle: heat is a predictable, recurring risk to which one must respond with a planned, measurable and targeted system — delaying adaptation is the most expensive scenario.

Part IV — Expected impacts and risks

Dimension Expected impact Risk
Economy Targeted compensation and storage expansion moderate the income and production loss from heat The investment requires an upfront public cost; with poor targeting the support leaks away
Society The active reaching of vulnerable groups can reduce heat-related mortality If the protocol stays formal, those most in need are left out
Energy and environment Storage capacity stabilises the peak load, reduces supply risk Without managing the duck curve, renewable expansion causes grid stress

The main trade-off is timing and targeting: the adaptation investment (storage, health reserve) costs money now, while its benefit appears at a future — as yet uncertainly timed — heatwave. The proposal tips to the risk side if the compensation becomes general and permanent: then it degenerates into a consumption-distorting, budget-burdening price cap, as we saw with the earlier utility-price measures. The proposal, by contrast, works if the intervention is targeted, automatic and time-bounded — it is for the duration of the shock, not forever.

Part V — Measurability and summary

5.1 What is worth tracking? (suggested KPIs)

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

  • Whether the cross-sectoral, numerical heat-alert protocol is ready for the next summer season.
  • Whether excess mortality attributable to heat falls among vulnerable groups (the elderly, the chronically ill).
  • Whether the annual storage-capacity expansion reaches the proposed 200–500 MW band.
  • Whether the legal frame of targeted, income-proportional energy-price compensation appears (instead of the all-encompassing price cap).
  • Whether work loss and production decline due to heat moderate in the most exposed sectors (agriculture, construction).

5.2 Summary

MIAK’s message to decision-makers and to the public alike: extreme heat is not a weather colour piece, but a system-level adaptation task that requires planning and investment — now, not after the next record. MIAK asks the government to adopt a numerical, cross-sectoral heat-alert protocol, to accelerate the storage-capacity expansion, and to prepare the framework of targeted, automatic energy-price compensation. This approach moves two MIAK foundational values: data-drivenness — because the effectiveness of heat protection is decided by measurement, not by improvisation — and universal representation — because the burden of heat falls on the most exposed (the elderly, the ill, the low-income), and targeted protection is precisely their representation in the climate crisis. The two are not abstract labels here: human lives and livelihoods hang on them.

Part VI — Justifications and further sources

6.1 Press framing by spectrum

The topic moved the whole spectrum, but with different emphases. The economic-professional band (Portfolio) framed heat as an economic risk: alongside the heat-record forecast it highlighted the income-reducing effect and the energy-market burden, backed with figures. The liberal-left and public-affairs band (Telex, 444.hu, HVG) focused on the direct everyday-life consequences — water restrictions, MVM’s request for thrift, the burden affecting even healthy young people. The conservative band treated heat on this day primarily as a news and everyday-life topic, less in a policy frame. Looking at the spectrum as a whole, it is striking that the system-level interpretation of heat — adaptation, energy resilience, health preparedness — appeared in relatively few places: the dominant framing was the acute event (“how many degrees will it be”), not the question of structural preparation.

6.4 Literature in detail

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

The central thesis of the report of the British economist Nicholas Stern is that adaptation is not an option, but a necessity, and delaying it is more expensive than preparing. The climate change of the coming decades can no longer be prevented, but societies and economies can be protected — with better information, planning and more resilient infrastructure.

“Adaptation to climate change — that is, taking steps to build resilience and minimise costs — is essential. … 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 dome this means that the heat-alert protocol and the storage-capacity investment are not a cost, but the avoidance of deferred, compounding damage — this is the logic that MIAK’s K7 and G25 programme points carry forward.

6.4.2 WHO: European Health Report 2024

The European report of the World Health Organization (WHO) approaches the health burden of climate change from the side of the most exposed. The report stresses that the protection of children, the elderly and the low-income requires special attention, while the health systems struggle with labour shortages and post-pandemic burnout.

“Specific attention is needed to protect the health of children, older people and people on low incomes.”

During the heat dome this thesis is directly operational: heat mortality overwhelmingly affects vulnerable groups, which is why MIAK’s E4 proposal puts their active reaching — not passive alerting — at the centre of the protocol.

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

The Canadian author Naomi Klein interprets record heat and natural disaster as a system-level crisis, not an isolated event. In her book she presents extreme temperature records — for example the 49.5-degree day of Port Augusta in South Australia in 2019 — as symptoms of a “climate emergency”, to which one must respond not with an individual alert, but with a coordinated social and economic programme. In the Hungarian reading this framing strengthens MIAK’s position: the heat dome is not a chance anomaly, but a recurring pattern that requires planned adaptation and the handling of the climate-social dual — the joint protection of the environment and of livelihood.

6.5 International comparison

For numerical heat protection the French heat plan (Plan Canicule) is the reference: after the 2003 European heatwave that claimed tens of thousands of lives, France built a level-based, mandatory action protocol that links the weather alert with health and municipal measures, and keeps a register of vulnerable residents. On the energy side, Southern European and Californian practice shows that the heat peak can be managed safely only with a storage capacity and demand-side flexibility large enough to bridge the evening fall-off of solar energy. Both models can be built into the Hungarian adaptation programme — as a concrete, accountable commitment, not an abstract principle.
