Experts have issued a “bigger than any in global history” warning for California. There is no earthquake. According to a recent study, the likelihood of a major California flood that would submerge Los Angeles, evict millions of people, and cause unprecedented devastation is increasing as the planet warms.

In the West, megadrought may be the greatest weather worry right now despite the ongoing danger of earthquakes and wildfires. However, a recent study warns that “Megafloods,” another calamity, are approaching California.
According to research issued on Friday, climate change is raising the likelihood of floods that might submerge cities and evict millions of people from their homes across the state.
It claims that hundreds of miles of California might receive feet of rain, or more than 100 inches in certain spots, during a severe month-long storm. Similar to how they are now, the area used to experience relentless storms before it was inhabited by tens of millions of people.
The likelihood and size of the next megaflood are already substantially rising with each degree of global warming, according to the study.
CLIMATE CONSEQUENCES:
Climate-related effects are connected to roughly 60% of human diseases.
HEAT:
Urban heat islands have gotten worse as a result of climate change and extreme weather.
According to co-author and UCLA climate scientist Daniel Swain, “the storm sequence is greater in almost every respect” when floods occur on a warmer globe. “There’s more rain overall, it rains harder and blows harder every hour.”
Climate change a factor in megafloods

Indeed, the study discovered that climate change makes such catastrophic flooding twice as likely. According to Swain, such huge statewide floods have occurred every century or two in California over the millennia, and the risk of similar occurrences today has been significantly overestimated.
The Great Flood of 1862 in California was much earlier than climate change, measuring up to 300 miles long and 60 miles across. The study found that a similar flood now would uproot 5 to 10 million people, cut off the state’s main roadways for weeks or months, cause significant economic harm, submerge important Central Valley cities, and even part of Los Angeles.
The interesting tasks on the “ArkStorm scenario” from 2010, are so dubbed because it describes the “atmospheric rivers” of moisture that would cause a flood of biblical proportions. This is the first step in a strategy called ArkStorm 2.0 to go over that scenario once more.
Unfortunately, the massive California flood would be a $1 trillion disaster.
According to UCLA, a flood the size of the one that occurred in 1862 would be considered a $1 trillion disaster.
“Even with the vast array of reservoirs, levees, and bypasses that exist today, portions of cities like Sacramento, Stockton, Fresno, and Los Angeles would be submerged. It would be the worst calamity in human history, costing an estimated $1 trillion, “based on the assertion.
Californians may have overlooked significant flooding because drought and wildfires have received so much attention, Swain said in the release. “While there is always a chance for serious wildfires in California, many years pass without any significant flood-related news. People disregard it.
According to UCLA, the researchers compared two extreme scenarios using new high-resolution weather models and existing climate models: one that would occur around once every century in the historical climate of recent decades and another in the expected climate of 2081-2100.
Both scenarios would feature a month-long succession of storms driven by atmospheric rivers.
What are atmospheric rivers?
Ribbons of water vapor known as atmospheric rivers run thousands of miles from the tropics to the western United States. They range in width from 250 to 375 miles, and they serve as the source of the intense rain and snowstorms that can result in flooding along the West Coast.
Despite being advantageous for water supplies, such occurrences can disrupt transport, trigger dangerous mudslides, and result in catastrophic loss of life and property, according to the National Oceanic and Atmospheric Administration.
According to studies, atmospheric rivers will become warmer, more intense, and more frequent as a result of climate change.
The research from last Friday was published in the American Association for the Advancement of Science’s peer-reviewed journal Science Advances.
