Migration Into America’s Most Flood-Prone Areas Has More Than Doubled Since the Start of the Pandemic

More from Redfin: “The most flood-prone U.S. counties saw 384,000 more people move in than out in 2021 and 2022—a 103% increase from the prior two years, when 189,000 more people moved in than out. The same trend took hold in the places most vulnerable to wildfires and heat as the pandemic homebuying boom and a housing affordability crisis pushed Americans into disaster-prone areas. The counties with the highest wildfire risk saw 446,000 more people move in than out over the past two years, a 51% increase from 2019 and 2020. And the counties with the highest heat risk saw 629,000 more people move in than out, a 17% uptick. This is according to a Redfin analysis of domestic migration data from the U.S. Census Bureau and climate-risk scores from First Street Foundation. We analyzed the counties in the contiguous U.S. that rank in the top 10% for flood and fire risk and the top 33% for heat risk, as measured by the share of residential properties at high risk.”

Heat Waves and Cold Snaps Linked to More Fatal Heart Attacks, Study Finds

More from Gizmodo: “The global rise in extreme weather is likely to bring along more fatal heart attacks, new research this week suggests. The study found that exposure to heat waves and cold snaps was associated with higher odds of heart attack deaths. This associated risk was even greater on extreme heat days that also featured high levels of certain air pollutants. The research was led by scientists at the Sun Yat-sen University in Guangzhou, China. The team analyzed recent data collected on recorded heart attack deaths from the Jiangsu province of the country, between 2015 to 2020. Then they cross-referenced that information with environmental data in the area, focusing on especially hot and cold days as well as levels of fine particulate matter (particles of air pollution that are smaller than 2.5 microns).”

Warming Could Push the Atlantic Past a ‘Tipping Point’ This Century

More from the New York Times: “The last time there was a major slowdown in the mighty network of ocean currents that shapes the climate around the North Atlantic, it seems to have plunged Europe into a deep cold for over a millennium. That was roughly 12,800 years ago, when not many people were around to experience it. But in recent decades, human-driven warming could be causing the currents to slow once more, and scientists have been working to determine whether and when they might undergo another great weakening, which would have ripple effects for weather patterns across a swath of the globe. A pair of researchers in Denmark this week put forth a bold answer: A sharp weakening of the currents, or even a shutdown, could be upon us by century’s end. It was a surprise even to the researchers that their analysis showed a potential collapse coming so soon, one of them, Susanne Ditlevsen, a professor of statistics at the University of Copenhagen, said in an interview. Climate scientists generally agree that the Atlantic circulation will decline this century, but there’s no consensus on whether it will stall out before 2100.”
