But when 80-degree temperatures visit the high Arctic, as they just did, and when sleet disrupts Mother’s Day weekend in May in Massachusetts, as it just did, thoughts turn to: What is going on here?

Climate Change Is Strengthening Typhoons, Hurricanes and Cyclones. The US Isn’t Paying Attention.

Alyssa Frederick, Ph.D. candidate; Steven Mana`oakamai Johnson, Ph.D. student, , UCS

On October 25th, one of the worst storms to strike US land hit the islands of Saipan and Tinian, killing two people and destroying thousands of homes. Because of Super Typhoon Yutu, the islands remain without power, and likely will for the months to come. Fresh water is scarce, and recovery efforts are hindered by lack of access and resources. (Read more about this here.)

Typhoons and hurricanes, or more generally, tropical cyclones, are all spinning storms of high winds (sustained winds of 73 miles per hour or greater) and intense weather like thunderstorms. The only nominal difference is the ocean basin where they originate. The most alarming factor they all share is that intensity and frequency of these cyclonic super storms is increasing with climate change. Read more >

U.S. Braced for Historic Inland Flooding and Coastal Storm Surge Even As Joaquin Blew Out to Sea

, senior climate scientist

Hurricane Joaquin, while a category 4, unleashed torrential rain over the Bahamas, uprooting trees, disrupting power and ripping rooftops. Joaquin lingered in the tropics, shedding vast amounts of moisture that became part of a complex mix of weather systems in the eastern U.S., creating soggy conditions even before Joaquin shifted northeastward from the tropics offshore of the U.S., giving a one-two punch for the eastern states. Punch one was life-threatening inland flooding, and punch two was storm surge along coastal areas. Read more >
