Hurricanes Helene and Milton Further Proof We’re Not Ready for Fossil Fuel-Caused Climate Change  

Union of Concerned Scientists

In August, the National Oceanic and Atmospheric Administration (NOAA) issued its updated forecast for the 2024 hurricane season. Significantly warmer than usual surface temperatures in the Atlantic Ocean, which come largely as a result of human-caused climate change. Why are the oceans so warm and fueling this rapid intensification?

New Research Sparks Concerns That Ocean Circulation Will Collapse

Yale E360

Scientists have long feared that warming could cause a breakdown of ocean circulation in the North Atlantic. But new research finds the real risk lies in Antarctica’s waters, where melting could disrupt currents in the next few decades, with profound impacts on global climate. Read more on E360 →

The Planet’s Big Blue Machine: Why the Ocean Engine Matters

Yale E360

The ocean is an enormous engine, turning heat energy into motion, says physicist Helen Czerski. But human activity is threatening that machine — depriving the seas of oxygen, increasing stratification, and potentially changing the currents that influence global weather. Read more on E360 →

The Race for EV Parts Leads to Risky Deep-Ocean Mining

Yale E360

Some companies say the solution lies in mining the deep oceans, but scientists say that could irreversibly damage a vast, largely pristine ecosystem. The electric vehicle boom is driving a surge in demand for prized metals needed for batteries and other components. Read more on E360 ?.

As Ocean Oxygen Levels Dip, Fish Face an Uncertain Future

Yale E360

Global warming not only increases ocean temperatures, it triggers a cascade of effects that are stripping the seas of oxygen. Fish are already moving to new waters in search of oxygen, and scientists are warning of the long-term threat to fish species and marine ecosystems. Read more on E360 →

Real Climate

In the real ocean that is not an observed quantity. While these simulations assimilate observational data, over most of the ocean surface these are basically sea surface temperatures, but surface heat loss depends also on air temperature, wind speed, humidity, radiation and cloud cover in complex ways, all of which are not accurately known.

Why Were 2023 and 2024 So Hot?

Union of Concerned Scientists

As industrial aerosols decreased due to this new regulation, particularly over the North Atlantic Ocean, the planetary albedo slightly decreased, which means that more incoming solar radiation was absorbed by the planet rather than reflected.
