Climate Change Is Increasing The Risk Of A California Megaflood Yale For arkstorm 2.0, we wanted to use the latest science and modeling tools to develop physically realistic month long megastorm and subsequent potential megaflood scenarios for california. We find that climate change has already increased the risk of a gf1862 like megaflood scenario in california, but that future climate warming will likely bring about even sharper risk increases.

Climate Change Is Increasing The Risk Of A California Megaflood Yale The arkstorm@sierrafront 2.0 effort will integrate stakeholder perspectives with analysis of new datasets to better understand the implications of flooding to populations and infrastructure in the region and identify ways to increase resilience to winter storms under a warming climate. We assess the cumulative and annual likelihood of a 30 day megastorm sequence capable of causing a california megaflood and find that both increase strongly as a function of climate warming. The arkstorm 1.0 scenario describes an extreme storm that devastates much of california, causing up to $725 billion in losses (mostly due to flooding and erosion), and affecting a quarter of california's homes. Building on the original (2011) arkstorm scenario, which aimed to understand the implications of a present day california megastorm, the arkstorm team developed two new climate aware scenarios: a historical (arkhist) & warmer future scenario (arkfuture), collectively called arkstorm 2.0 (figure 1).

Climate Change Doubles Megaflood Risk In California Climate The arkstorm 1.0 scenario describes an extreme storm that devastates much of california, causing up to $725 billion in losses (mostly due to flooding and erosion), and affecting a quarter of california's homes. Building on the original (2011) arkstorm scenario, which aimed to understand the implications of a present day california megastorm, the arkstorm team developed two new climate aware scenarios: a historical (arkhist) & warmer future scenario (arkfuture), collectively called arkstorm 2.0 (figure 1). Although california is currently contending with historic drought, a new study indicates that climate change is sharply increasing the risk of a catastrophic megaflood that could submerge large swaths of the state and displace millions of residents. The arkstorm 2.0 simulations build upon a scenario developed in 2010 by the us geological survey, where large atmospheric rivers dump extreme quantities of rainfall over california and cause widespread flooding. A 2022 study found that climate change has doubled the risk of a present day megastorm and more than tripled the risk of a trillion dollar megaflood. this increase in extreme storm sequences capable of generating severe flooding in california is a significant concern. In particular, a 2022 study found that, relative to a century ago, climate change has already doubled the risk of a present day megastorm, and more than tripled the risk of a trillion dollar megaflood of the type that could swamp the central valley.
