A new study shows a clear regional divide in future US hurricane landfalls: while tropical cyclone frequency is projected to decline along the Gulf Coast—including Texas—it will steadily increase along the Southeastern US coastline throughout the 21st century. 🌊🧪 ocean2climate.org/2026/09/29/f...

Future Tropical Cyclone Risk in the Gulf Drops while the Southeast Braces for Impact

A new study argues that natural multidecadal trade wind shifts—rather than a failure of climate models—primarily drove the unexpected cooling of the eastern tropical Pacific from 1982 to 2024, masking greenhouse-gas warming in the region temporarily. 🌊🧪 ocean2climate.org/2026/09/01/w...

Why the Pacific is Cooling in a Warming World

This in-press article argues that historical flood events in the US Mid-Atlantic Bight are linked to the Indian Ocean Dipole (IOD) via its impact on the AMOC. This is a provocative claim that warrants further scrutiny, but it is thought-provoking nonetheless. 🌊🧪 ocean2climate.org/2026/08/27/i...

This study by Cui et al. (2026) discusses why the South Atlantic is getting saltier. It is due to both local (increased Evaporation minus Precipitation) and remote drivers (enhanced intrusion of warm & salty surface water from the Indian Ocean). 🌊🧪 ocean2climate.org/2026/08/22/w...

Why the South Atlantic is Getting Saltier and Why It Matters for Our Climate

Xing et al. (2025) shows that historical global warming SST patterns project onto the PDO and alter its spatial pattern. Consequently, cleanly separating the PDO—as a natural internal oscillation—from the background global warming signal is virtually impossible. 🌊🧪 ocean2climate.org/2026/08/19/i...

Is Global Warming Changing the Pacific Ocean’s Natural Cycles?

Sea surface temperature anomalies in the tropical Eastern Pacific don't just affect short-term climate patterns in the North Atlantic—they also drive long-term shifts, the Atlantic Multidecadal Oscillation (AMO), a decade later by altering deep ocean convection: 🌊🧪 ocean2climate.org/2026/08/19/s...

This satellite altimetry plot compares sea surface height anomalies on July 30–31 between the 2023 and 2026 El Niño events. With a peak Niño-3.4 index of +2.0 °C, the 2023–24 El Niño was the fifth-strongest event since 1950. But it is nothing compared to what is developing now. 🌊🧪

What if the Indonesian Throughflow (ITF) were to stop? Shutting off this critical ocean valve between the Pacific and the Indian Ocean could trigger a permanent El Niño state and reshape global weather patterns. Here’s what models show 🌊🧪 ocean2climate.org/2026/07/31/w...

What Happens to the Planet if the Indonesian Throughflow Stops?

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on several studies, including “The Role of Indonesian Throughflow in a Global Ocean GCM.” by Hirst and Godfr…

Meanwhile, in the Indian Ocean, a Java–Sumatra Niña is about to form. It typically peaks in July–September, often occurring during the developing phase of El Niño, and serves as a precursor to a positive Indian Ocean Dipole (+IOD) event in September–November. 🌊🧪

Weather noise tends to disrupt warm-water volume discharge after the El Niño peak, increasing the likelihood that positive recharge persists into the following year. This highlights the importance of resolving weather in seasonal forecast models: 🌊🧪 agupubs.onlinelibrary.wiley.com/doi/10.1029/...

Both the El Niño cycle & local Atlantic sea surface temperature patterns can drive up the total number of landfalling storms. However, only El Niño controls the percentage of storms that actually hit land because El Niño actively shifts the winds that steer these storms. 🌊🧪 doi.org/10.1029/2026...

It is too early to tell. But, it appears that Atlantic Nina is about to form. It is not unusual to have a cold event forming during the developing phase of strong El Nino event. Atlantic Nina tends to suppress Cabo Verde Hurricanes, which often become a major hurricane to hit Caribbean islands.🌊🧪
