Seafire belt reshapes global climate model

The world’s oceans are heating up in two different bands that spun around the world, having potentially far-reaching impacts on weather patterns and marine ecosystems. New research shows that these warming areas are located near 40 degrees in the latitude of both hemispheres, creating a compelling pattern that has emerged since 2005.

“It’s really surprising,” said Dr. Kevin Trenberth of the University of Auckland and the National Center for Atmospheric Research. “It’s unusual to find this unique pattern that jumps out of climate data.”

The study, published in the Journal of Climate, analyzed “unprecedented” atmospheric and ocean data from a 1-degree latitude bar, with a depth of 2,000 meters between 2000 and 2023. The research team found that in the 40-45 degree band, the fastest warming occurs at 40-45 degrees Celsius, especially in the new Zealand, tasmania and Arganty and Arginant, Anderant and at and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and and The second important warm band is in NATO 40 degrees, most notably east of Japan and the United States.

“Although Donald Trump thought about something, the climate is changing due to the accumulation of greenhouse gases, and most of the extra heat ends up in the ocean,” Termburs said. “However, the results are by no means unified, as this study shows. Natural variability may also be at work.”

Surprisingly, the subtropical zones near 20 degrees of the two hemispheres have hardly warmed. “What is unusual is that there is no warming in the subtropical zones of both hemispheres, close to 20 degrees of latitude,” Trenberth noted.

The researchers transferred these tropical regions to the poles in the jet stream (high winds supplying power above the Earth’s surface) and the corresponding changes in ocean currents. These changes in atmospheric circulation alter surface heat exchange and heat transfer within the ocean.

Although the tropical regions from north to 20 degrees also showed considerable warming, the pattern has less variation due to differences caused by the El Niño southern oscillation.

Ocean heating has significant consequences, destroying marine ecosystems, increasing atmospheric water vapor (effective greenhouse gases), and exacerbating extreme weather events. The study estimates that by 2040, satellite reincome emissions could reach 10,000 metric tons per year compared to some forecasts, conservatively.

The results show that although climate change manifests globally, its effects are uneven, creating complex patterns that will shape regional climate futures in different ways across the planet in different ways.
