Biography
Amir AghaKouchak is a Professor of Civil and Environmental Engineering and Earth System Science at the University of California, Irvine. His research focuses on natural hazards and climate extremes and crosses the boundaries between hydrology, climatology, remote sensing. One of his main research areas is studying and understanding the interactions between different types of climatic and non-climatic hazards including compound and cascading events. He has received a number of honors and awards including the American Geophysical Union’s James B. Macelwane Medal and the American Society of Civil Engineers (ASCE) Huber Research Prize. Amir is currently serving as the Editor-in-Chief of Earth’s Future. He has served as the principal investigator of several interdisciplinary research grants funded by the National Aeronautics and Space Administration (NASA), National Science Foundation (NSF), and National Oceanic and Atmospheric Administration (NOAA). Amir has a passion for nature and landscape photography, and he uses his photos for creating educational materials.

100 days of 100-degree misery: A summer of relentless, oppressive heat across the West
Los Angeles Times online
2024-09-05
While California’s climate has always had year-to-year and month-to-month variability, the heat the state has experienced recently is consistent with climate change, according to Jane Baldwin, assistant professor of earth system science at UC Irvine. … Los Angeles is an urban heat island … The disparity in climate resilience is even visible from neighborhood to neighborhood, Amir AghaKouchak, a UC Irvine civil and environmental engineering professor, said. More affluent areas are better protected from extreme heat with vegetation and shade, while poorer areas have less shade and air conditioning.
Iran’s Extreme Heatwave Underscores Urgent Need For Climate Action

But with temperatures in Iran rapidly rising, experts are urging the government and international organizations to ramp up efforts to address a lesser-discussed crisis at hand. Unfortunately, “when it comes to heatwaves, they don’t get the attention they deserve,” says Amir Aghakouchak, professor of civil and environmental engineering at the University of California, Irvine.
After winter storms, California can expect a late start to the wildfire season

Still, as climate change pushes California fires to burn at higher elevations — places that were once too wet or cool to nurture flames — more snow is falling on burned areas, said Amir AghaKouchak, professor of civil and environmental engineering at UC Irvine. … “So potentially, more and more fire snow interactions can contribute to a stronger or more rapid change from flood risk to drought risk,” he said.
How California’s storms are projected to become more extreme with climate change
Los Angeles Times online

“Higher rain over snow ratio, faster snowmelt, and more intense storms can significantly impact water resource management in California,” said Amir AghaKouchak, a UC Irvine professor of civil and environmental engineering. “A shift toward more intense rain, as opposed to snow, will strain an already water-challenged environment to its limit.” … In a 2022 study, researchers at UC Irvine found that in the Los Angeles Basin, nearly 1 million people live in areas that could be threatened in a 100-year flood, and that Black and low-income communities are especially vulnerable.

“That’s how sensitive the system is to snow — one single degree of temperature change,” said Amir AghaKouchak, professor of civil and environmental engineering at the University of California, Irvine. “The implications are huge, both for ecosystems that don’t get a lot of attention and also drinking water.” AghaKouchak and Laurie Huning, an assistant professor of civil engineering at California State University, Long Beach, published the first global analysis of snow drought in 2020. They found that several mountain regions saw an uptick in snow drought intensity, length and frequency in the first 18 years of this century compared to the 19 years preceding it.
University Of California Irvine Study Finds Human-Caused Climate Change To Blame For Increase In California’s Wildfires
India Education Diary online

Researchers at the University of California and other international institutions have concluded that nearly all of the increase in scorched terrain can be blamed on human-caused climate change. ... “The 10 largest fires in California history have all occurred in the past two decades, and five of those have happened since 2020,” said co-author Amir AghaKouchak, UCI professor of civil and environmental engineering [associate director of Center for Hydrometeorology & Remote Sensing (CHRS)]. “Through our study, it has become clear that anthropogenic climate change is the major driver of this increase in wildfire damage.”

Wildfire burn areas in California are growing ever larger due to greenhouse gas emissions

Study authors determined that California wildfires consumed five times more area between 1996 and 2021 than in the 25 years prior — an increase chiefly attributed to climate change. Researchers also determined that the 50-year period as a whole saw a 172% increase in burn area. “This is very, very high,” said study co-author Amir AghaKouchak, a professor of civil and environmental engineering at UC Irvine. “Even if it was much lower, still it would be significant, but 172% is really serious.”

Changes in the exposure of California's Levee-Protected Critical Infrastructure to flooding hazard in a warming climate
Environmental Research Letters2020 Levee systems are an important part of California's water infrastructure, engineered to provide resilience against flooding and reduce flood losses. The growth in California is partly associated with costly infrastructure developments that led to population expansion in the levee protected areas.
Impacts of ozone and climate change on yields of perennial crops in California
Nature Food2020 Changes in temperature and air pollution affect agricultural productivity, but most relevant research has focused on major annual crops (for example, wheat, maize, soy and rice). In contrast, relatively little is known about the effects of climate change and air quality on perennial crops such as fruits and nuts, which are important to dietary diversity and nutrition, and represent ~38% of California’s agriculture by economic value.
Flash droughts present a new challenge for subseasonal-to-seasonal prediction
Nature Climate Change volume2020 Flash droughts are a recently recognized type of extreme event distinguished by sudden onset and rapid intensification of drought conditions with severe impacts. They unfold on subseasonal-to-seasonal timescales (weeks to months), presenting a new challenge for the surge of interest in improving subseasonal-to-seasonal prediction. Here we discuss existing prediction capability for flash droughts and what is needed to establish their predictability.
Climate Extremes and Compound Hazards in a Warming World
Annual Review of Earth and Planetary Sciences2020 Climate extremes threaten human health, economic stability, and the well-being of natural and built environments (e.g., 2003 European heat wave). As the world continues to warm, climate hazards are expected to increase in frequency and intensity. The impacts of extreme events will also be more severe due to the increased exposure (growing population and development) and vulnerability (aging infrastructure) of human settlements.
How do natural hazards cascade to cause disasters?
Nature2018 This has been an exceptional year so far for natural disasters. Typhoons in Asia and Hurricane Florence hitting the US east coast have caused extensive damage, flooding and mudslides. In the past two months, Scandinavia, Spain and Portugal, the United Kingdom, North America and South Africa experienced fierce forest blazes.
Mountain snowpack response to different levels of warming
PNAS2018 Across the world, the seasonal montane snowpack stores and releases substantial amounts of water annually. As the global temperature is projected to rise, it becomes increasingly important to assess the vulnerability of the mountain snowpack. We therefore turn to the historical record to understand the extent to which snow water equivalent (SWE) and its centroid respond to different levels of warming.
Compounding effects of sea level rise and fluvial flooding
PNAS2017 Population and assets in coastal regions are threatened by both oceanic and fluvial flooding hazards. Common flood hazard assessment practices typically focus on one flood driver at a time and ignore potential compounding impacts.
