Who’s vulnerable to extreme heat and how can we protect them?

December 6, 2023

High Horizons

According to the World Meteorological Organization (WMO), heatwave events have increased sixfold since the 1980s, driven by the naturally occurring El Nino and exacerbated by human-induced warming from greenhouse gases. Current projections say we’re 1.2oC warmer than pre-industrial levels, and global warming is likely to reach 1.5°C between 2030 and 2052. These extreme heat events are having a disproportionate impact on already vulnerable populations – including pregnant women, newborns, and children.

Extreme heat is the No. 1 climate-related cause of death in the U.S. Race and location also matter in determining how much things are heating up. On National Public Radio’s Code Switch, journalist Shereen Marisol Meraji pointed out: “Mother Nature may not discriminate, but people do,” succinctly describing the disproportionate impact of extreme and urban heat on communities of color as a result of federally mandated racist housing policies.

NASA Earth Exchange Global Daily Downscaled Projections (NEX-GDDP-CMIP6)

November 3, 2023

NASA Center for Climate Simulation

The NEX-GDDP-CMIP6 dataset is comprised of global downscaled climate scenarios derived from the General Circulation Model (GCM) runs conducted under the Coupled Model Intercomparison Project Phase 6 (CMIP6) and across all four “Tier 1” greenhouse gas emissions scenarios known as Shared Socioeconomic Pathways (SSPs). The CMIP6 GCM runs were developed in support of the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC AR6). This dataset includes downscaled projections from ScenarioMIP model runs for which daily scenarios were produced and distributed through the Earth System Grid Federation. The purpose of this dataset is to provide a set of global, high resolution, bias-corrected climate change projections that can be used to evaluate climate change impacts on processes that are sensitive to finer-scale climate gradients and the effects of local topography on climate conditions.

Modeling extreme heat in a changing climate

September 5, 2023

Oriana Chegwidden Jeremy Freeman

If it wasn’t clear before the summer of 2023 that climate change is raising temperatures, it better be clear now. This past July broke the record for the hottest month ever measured. And that was before a life-threatening heat dome boiled large swaths of the US Midwest in August. As extreme heat becomes commonplace, people need to know when and where it will occur. But modeling and predicting heat is complicated. Temperature on its own doesn’t tell the whole story. For example, when it’s hot you sweat, and the water evaporates to cool you down. But if there’s too much moisture in the air (high humidity), that cooling effect can stop working. The amounts of sunlight and wind also matter (the former heats you up, and the latter cools you down). These parameters vary from minute to minute. And they vary geographically, often at fine spatial scales, especially within cities where human activity and infrastructure trap heat. We want to help planners and the public navigate this complicated science by producing actionable data that will make it easier to understand the risks. As part of a collaborative project with The Washington Post, we developed a new dataset modeling extreme heat under a changing climate. We built on a foundation of academic work, aiming to combine the best pieces of several existing methods and datasets to produce something new, albeit with several assumptions and approximations. And we’re making all of our data, methods, and code fully public. In this explainer we describe how and why we developed the new dataset, and provide details on our methods, assumptions, and results.

California Lessons for Federal & State Workplace Heat Rules

September 14, 2022

Juanita Constible NRDC

California’s recent record-breaking heat was particularly brutal for the workers who walk for miles, lift heavy loads, sweat in oppressively hot uniforms, and endure bosses who care more for their profits than their people. School cafeteria workers, farmworkers, delivery drivers, and others across the state experienced unhealthy temperatures that left them faint, in the hospital, or worse. These are just a few examples of the kind of preventable harm workers face every year from heat. But they’re particularly infuriating coming from California, which is one of only five states in the country with workplace heat stress protections. What’s going wrong?

Extreme heat events affect different people in different ways, and some people are at higher risk of experiencing heat-related illness if they do not have air conditioning. One way to reduce the public health impacts of extreme heat events is to check in regularly with susceptible people to see how they are coping. However, not everyone knows who is at most risk, how to recognize heat-related illness, or what to do in risky situations. This tool from the NCCEH was designed to help support people doing heat checks by providing all they key information and guidance in a 5-page package. This tool has been co-developed with Dr. Glen Kenny and his heat stress research group at the University of Ottawa.

Sameer Kwatra NRDC

India, currently battling a severe second wave of the COVID-19 pandemic, is facing multiple climate stressors simultaneously. Most of the country is already facing peak summer heat, and this week, many coastal states are also dealing with the effects of Cyclone Tauktoe. Fueled by climate change, heatwaves and other extreme weather events are longer, more frequent, and more intense. Long-term resilience is critical to build a public health infrastructure that is robust enough to withstand severe short-term crises such as the current pandemic and persistent climate stressors such as extreme heat. Fortunately, many states and cities are taking action.

Cool Infrastructures

At the beginning of the COVID-19 pandemic, it became clear that poor communities living in high density urban environments across low- and middle-income countries in the Global South would confront the combined effects of COVID-19 and extreme heat. Whilst mitigation measures – such as lock-downs, home quarantines and social distancing – were going to prove difficult for affluent communities who had the means and space to follow them – they looked set to be devastating for communities living in high density informal settlements in urban areas. Mitigation measures looked set to exacerbate already precarious livelihoods by reducing income opportunities and exposing populations to heat stress, by keeping people in poorly insulated and poorly ventilated housing and reducing access to external cooling and hydration infrastructures and services.
