Physical drivers of the November 2023 heatwave in Rio de Janeiro Open
Because extreme heat has not historically been a major hazard for the city of Rio de Janeiro, the November 2023 Heatwave magnitude and timing were staggering. Here we conduct a case study of reanalysis data and high-resolution projections …

Physical Drivers of the November 2023 Heatwave in Rio de Janeiro Open
As extreme heat has not historically been a major hazard for the city of Rio de Janeiro, the November 2023 Heatwave magnitude and timing were staggering. Here we conduct a case study of reanalysis data and high-resolution projections to ex…
Mortality impacts of the most extreme heat events Open
Extreme heat threatens human life, evidenced by >260,000 heat-related fatalities collectively in the deadliest events since 2000. In this Review, we link physical climate science with heat mortality risk, including crossings of uncompensab…
Heat disproportionately kills young people: Evidence from wet-bulb temperature in Mexico Open
Recent studies project that temperature-related mortality will be the largest source of damage from climate change, with particular concern for the elderly whom it is believed bear the largest heat-related mortality risk. We study heat and…

Subseasonal Variability of Humid Heat During the South Asian Summer Monsoon Open
The South Asian summer monsoon strongly modulates regional temperature and humidity. While extreme dry heat peaks in the pre‐monsoon season, recent literature suggests that extreme humid heat can continue to build throughout the monsoon se…
Stickiness: A New Variable to Characterize the Temperature and Humidity Contributions toward Humid Heat Open
Extreme wet-bulb temperatures ( T w ) are often used as indicators of heat stress. However, humid heat extremes are fundamentally compound events, and a given T w can be generated by various combinations of temperature and humidity. Differ…
Future warming from global food consumption Open
Food consumption is a major source of greenhouse gas (GHG) emissions, and evaluating its future warming impact is crucial for guiding climate mitigation action. However, the lack of granularity in reporting food item emissions and the wide…
Stickiness: A New Variable to Characterize the Temperature and Humidity Contributions toward Extreme Humid Heat Open
Extreme values of wet bulb temperature are often used as indicators of heat stress for humans and other animals. However, humid heat extremes are fundamentally compound events, and a given wet bulb temperature can be generated by various c…
Evidence of Rapidly Increasing Dangerous Humid-Heat Risk in Africa's Great Green Wall Open
<p>Since the 1980s, air temperatures have precipitously risen across the African Sahel due to climate change. Currently, the Sahel has rapidly greened. While the drivers of such land-cover and land-use change (LCLUC) across this dryl…
Future Warming from Global Food Consumption Open
Food consumption is a major source of greenhouse gases emissions, and evaluating its future warming impact is crucial for guiding climate mitigation action. However, the lack of granularity in reporting greenhouse gas emissions from food i…
The Influence of Intraseasonal Oscillations on Humid Heat in the Persian Gulf and South Asia Open
Humans’ essential ability to combat heat stress through sweat-based evaporative cooling is modulated by ambient air temperature and humidity, making humid heat a critical factor for human health. In this study, we relate the occurrence of …
Concentrated and Intensifying Humid Heat Extremes in the IPCC AR6 Regions Open
Extreme humid heat events have seen rapid increases globally in recent decades, but regional changes and higher‐order temporal characteristics, such as interannual and intra‐annual clustering, have not been widely explored. Using ERA5 rean…
On the Controlling Factors for Globally Extreme Humid Heat Open
Humid heat presents a major societal challenge through its impacts on human health, energy demand, and economic productivity, underlined by the projected emergence of conditions beyond human tolerance. However, systematic assessment of wha…
Climate benefits of proposed carbon dioxide mitigation strategies for international shipping and aviation Open
While individual countries work to achieve and strengthen their nationally determined contributions (NDCs) to the Paris Agreement, the growing emissions from two economic sectors remain largely outside most countries' NDCs: international s…
