A First: Category 5 Storms Have Formed in Every Ocean Basin this Year – the Washington Post

Human-caused climate change and El Niño have heated ocean waters to record levels, giving tropical storms a boost, scientists say…

For the first time on record, storms have reached top-tier Category 5 strength in every tropical ocean basin in the same year.

A combination of human-caused climate change and El Niño have heated ocean waters to record levels in 2023, setting the stage for this meteorological feat. The Copernicus Climate Service of the European Union confirmed that the global ocean reached its warmest level on record in August.

This week alone, two tropical cyclones leaped to Category 5 intensity in two days — Hurricane Jova in the northeastern Pacific on Wednesday, closely followed by Hurricane Lee in the Atlantic on Thursday. The pair of storms intensified with astonishing haste, their peak winds increasing 90 mph and 85 mph, respectively, in 24 hours.

Meteorologists monitor seven tropical oceans basins around the world for storm development. In addition to the Atlantic and eastern Pacific, Category 5 storms formed in the other five basins earlier this year.

Brian McNoldy, a tropical weather expert at the University of Miami, confirmed that 2023 marked the first instance of Category 5 storms in all seven and linked it to the warm waters.

“I think it’s reasonable to hypothesize that the abnormally warm ocean temperatures around the world made this more likely to happen,” McNoldy said in an email. “Gives everything a boost…”

How sea level rise made Idalia’s storm surge worse – the Washington Post

In mid-November 2021, a great storm begins brewing in the central Pacific Ocean north of Hawai‘i. Especially warm water, heated by the sun, steams off the sea surface and funnels into the sky.

A tendril of this floating moisture sweeps eastward across the ocean. It rides the winds for a day until it reaches the coasts of British Columbia and Washington State. There, the storm hits air turbulence, which pushes it into position—straight over British Columbia’s Fraser River valley….

Sorry, Honey, It’s Too Hot for Camp (Podcast) – Atlantic Radio

Summer is getting too hot and dangerous, killing the childhood of our imaginations.

A heat dome in Texas. Wildfire smoke polluting the air in the East and Midwest. The signs are everywhere that our children’s summers will look nothing like our own. In this episode, we talk with the climate writer Emma Pattee about how hot is too hot to go outside. The research is thin and the misconceptions are many—but experts are quickly looking into nuances of how and why children suffer in the heat, so we can prepare for a future that’s already here…

On Monday, the average global temperature reached 17.01 degrees Celsius (62.62 Fahrenheit), the highest in the US National Centers for Environmental Prediction’s data, which goes back to 1979. On Tuesday, it climbed even further, reaching 17.18 degrees Celsius and global temperature remained at this record-high on Wednesday…

Why a sudden surge of broken heat records is scaring scientists – the Washington Post

New precedents have been set in recent weeks and months, surprising some scientists with their swift evolution: historically warm oceans, with North Atlantic temperatures already nearing their typical annual peak; unparalleled low sea ice levels around Antarctica, where global warming impacts had, until now, been slower to appear; and the planet experiencing its warmest June ever charted, according to new data. And then, on Monday, came Earth’s hottest day in at least 125,000 years. Tuesday was hotter…
