Climate Week NYC, catastrophic flooding and a hefty price tag

The Climate, Health & Equity Brief is GMMB’s take on the last two weeks’ news on the current impacts of climate change. If you haven’t subscribed yet, you can do so by clicking here.

Hot Topic: On the brink. As world leaders and activists gathered this week in New York City to spotlight the climate crisis and discuss progress to mitigate its impacts, the world’s most vulnerable communities continue to reel from devastating losses caused by extreme weather.

Torrential downpours caused epic devastation in Libya, where nearly 4,000 are confirmed dead, 43,000 people have been displaced and 9,000 people remain missing. Muddy, fast-moving floodwaters swept away entire neighborhoods, destroyed thousands of homes and businesses, sank countless vehicles and made immediate rescue efforts nearly impossible. Meanwhile, findings from a new study revealed that human-caused climate change is making extreme flooding 50 times more likely to occur.

Fears of such climate devastation have spurred nine small island nations to pursue legal action, petitioning the International Tribunal for the Law of the Sea to apply UN ocean pollution laws to CO2 emissions and noting that some islands will be completely submerged by 2050 if warming continues unabated. A decision, which is expected to have global repercussions, is expected in 2024.

On the home front, a record 23 extreme weather events costing more than $1 billion each have taken place so far in 2023—with a total price tag estimated at $57.6 billion—prompting the Federal Emergency Management Agency (FEMA) to request an additional $16 billion in emergency funding to restock the depleted Disaster Relief Fund.

And the impacts of extreme weather are continuing to reshape the American housing market. A new study revealed that roughly 83% of potential home buyers now consider climate risks when shopping for homes, though many say they won’t actually move to areas with fewer climate risks, in large part due to affordability. And a separate study found that one-fourth of U.S. homes now face skyrocketing insurance premiums or are having their coverage completely revoked due to climate risks, making their homes much harder to afford—and very difficult to sell.

With a new study in Science Advances finding that six out of nine environmental indicators are now outside “safe operating boundaries for humanity” and commitments from the world’s biggest polluters lacking at Climate Week, action to turn the tide at COP28 in December has never been more necessary—or urgent.

Human Health

According to official figures released this week, nearly 4,000 people have died, 43,000 have been displaced, and an estimated 10,000 are still missing due to epic flooding in Libya, and new research found that human-caused climate change has made such floods 50 times more likely.

Planetary Health

According to a study in Science Advances, Earth has surpassed the “safe operating space for humanity” in six out of nine crucial environmental indicators, with the current state of the climate, biodiversity, land, freshwater, nutrient pollution, and “novel” chemicals all posing a grave threat to the planet.

Politics & Economy

With U.N. Climate Week underway, The U.S. and the European Union are promoting clean energy and activists and environmentalists are urging leaders to crack down on fossil fuel use, and some countries issued new commitments—but none have come from the world’s biggest atmospheric polluters.
