A warming climate brings both higher average and peak temperatures – putting stress on humans, animals, crops, and infrastructure systems, including energy supply and demand. But how will people and institutions cope with warmer temperatures, what is our capacity to adapt to changing conditions and what are the subsequent implications of our adaptation choices?

Strategies to sustainable manage cooling access and heat stress © Mastrucci & Byers | IIASA

Combining climate impacts, econometric and integrated assessment models, ongoing work explores the key drivers of capacity to adapt to climate impacts like heat stress and subsequent energy and emissions implications of keeping us cool.

A number of researchers in the ECE program have worked intensively on the nexus between global warming, heat stress and heat waves, air conditioning access, vulnerability and energy demands. This includes:

  • development of spatial climate indicators on cooling degree days and heat stress events, including use of wet bulb temperatures
  • projections of access to cooling and the cooling gap (Mastrucci et al. 2018; Andrijevic et al. 2020)
  • estimates of heat stress and residential cooling demands in megacities and for the world (van Ruijven et al 2018; Mastrucci et al. 2020, 2021)
  • age-dependent exposure and vulnerability (Thiery et al 2021; Carr et al. 2023

Extreme heat is particularly hard on older adults – an aging population and climate change put ever more people at risk

Scorching temperatures have put millions of Americans in danger this summer, with heat extremes stretching from coast to coast in the Southern US. IIASA researcher Giacomo Falcetta and colleagues from Boston University looked into this issue in an article recently published on The Conversation.

Projections of cooling gap from CHILLED model

Cooling and Heating gLobaL Energy Demand model (CHILLED)

CHILLED is a global scope, spatially explicit and physically based model for estimation of building space heating and cooling requirements. It combines high resolution climate data, building physics representation and socioeconomic and behavioural data. CHILLED is used for estimating long term growth in demand for space conditioning (heating & cooling), the associated energy demands and carbon emissions, and the population lacking cooling access (cooling gap).

Climate Solutions Explorer (CSE)

The new website is designed to provide latest information on climate mitigation and climate impacts, and aims to be a comprehensive resource for individuals, businesses, and policymakers looking to use some of the latest data from research on climate impacts and net zero mitigation pathways. The CSE website features a range of content, including and interactive map of climate change impacts, national and regional data dashboards of impacts and mitigation pathways, and interactive articles on a range of climate topics and countries.
