Solution

Although the formation of heat domes is governed by large-scale atmospheric dynamics, the underlying driver, anthropogenic global warming, is something we can directly influence. Following the structure of our previous analysis, the response to heat domes can be organized into two complementary strategies. The first is mitigation, which targets the root cause by reducing greenhouse gas emissions. The second is adaptation, which manages the consequences that are already locked into the climate system.

1. Mitigation, Reducing the Root Cause

Heat domes are not directly created by global warming, but, as shown in our results, rising baseline temperatures intensify both their severity and their frequency. Therefore, the most fundamental long-term solution is to slow down global warming itself by decreasing greenhouse gas emissions, particularly carbon dioxide (CO₂) and methane (CH₄), which are the dominant contributors to anthropogenic radiative forcing (IPCC, 2021).

The most effective pathway is to reduce the combustion of fossil fuels such as coal, oil, and natural gas, and to replace them with renewable energy sources including solar photovoltaics, wind power, and other low-carbon alternatives. Decarbonization of the energy sector not only lowers atmospheric CO₂ concentrations over time but also reduces the rate of Arctic amplification, which in turn helps restore a stronger equator-to-pole temperature gradient. A stronger gradient supports a more zonal jet stream and reduces the likelihood of persistent atmospheric blocking patterns that lock heat domes in place (White et al., 2023). In other words, mitigation does not eliminate heat domes, but it weakens the climatic foundation on which extreme heat events build.

2. Adaptation, Coping with the Change

Even under aggressive emission reduction scenarios, the warming already accumulated in the climate system will persist for decades. For this reason, adaptation is not optional. It is a necessary complement to mitigation.

Adaptation strategies should focus on reducing human exposure to extreme heat, with particular attention to urban environments where the Urban Heat Island (UHI) effect amplifies background temperatures. Three approaches are especially relevant.

First, improving urban air circulation. Dense building configurations trap heat and limit ventilation, allowing temperatures to rise well above those of surrounding rural areas. Urban planning that incorporates open layouts and reduced surface heat retention can ease this trapping effect.

Second, expanding green infrastructure. Trees and vegetated surfaces lower local temperatures through shading and evapotranspiration, and they also reduce sensible heat flux from impervious surfaces such as asphalt and concrete. Greater vegetation cover therefore directly counteracts the dry-surface feedback loop discussed in our Results section.

Third, constructing wind corridors. Strategically designed urban pathways allow cooler air from surrounding forests and water bodies to flow into city centers, mechanically displacing the stagnant warm air that accumulates beneath a high-pressure ridge. These adaptive measures cannot prevent the synoptic-scale conditions that produce heat domes, but they meaningfully reduce the local intensity and the public health impact of extreme heat at the surface.

Conclusion

A realistic response to heat domes requires both approaches working in parallel. Mitigation addresses the thermodynamic foundation by curbing greenhouse gas emissions, while adaptation reduces near-term human vulnerability through urban design and ecological restoration. As heat domes are projected to become more frequent and severe under continued warming, integrating these two strategies is essential for building climate resilience.
