The November Surprise: Why Caribbean Hurricanes are Doubling in Intensity and Frequency

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Recent Increasing Trend in October–November Caribbean Tropical Cyclone Activity” by Klotzbach. (2026). This research analyzes the significant increase in Caribbean tropical cyclone activity during October and November from 1979 to 2024. The authors identify a doubling of hurricane-strength storms and landfalls in recent decades, driven... Continue Reading →

More Pixels Solved the Pacific Ocean’s Cooling Mystery

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Km-scale coupled simulation and model–observation SST trend discrepancy” by Kang et al. (2026). This research article investigates why traditional climate models fail to replicate the observed cooling in the Southern Ocean and southeastern tropical Pacific. By utilizing the ICON coupled model at a kilometer-scale resolution,... Continue Reading →

How Dry Skies Sustain Multiyear La Niña

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Rainfall sustains multiyear La Niña”  by Tian et al. (2026). This research investigates how rainfall-induced salinity changes act as a critical feedback loop to sustain multiyear La Niña events. While early stages of these cooling events are driven by ocean dynamics like advection, the study reveals... Continue Reading →

The Atlantic’s Long Reach: How tropical Ocean Warming Fuels Greenland’s Melt

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Surface warming over Greenland amplified by remote forcing from tropical Atlantic” by Zhang et al. (2025). Recent research indicates that sea surface temperature variability in the tropical North Atlantic acts as a remote driver for the significant warming of the Greenland... Continue Reading →

Fingerprint Of Global Warming On Tropical Oceans Has Emerged In The Atlantic—While the Pacific Stays Cool

This blog post and the “Deep Dive” podcast, created by NotebookLM, are based on “Emergence of the enhanced equatorial Atlantic warming as a fingerprint of global warming” by Dong et al. (2025). Summary: This research identifies enhanced equatorial warming (EEW)—a pattern where sea surface temperatures near the equator rise faster than the surrounding tropics—as a... Continue Reading →

The Atlantic’s Slowing “Heartbeat”: How a Fading Ocean Current Is Silencing a Major Climate Pattern

This blog post and the “Debate” podcast on a paper “Atlantic Meridional Overturning Circulation slowdown suppresses Atlantic Niño variability” by Freire-SouzaLi et al. (2025) was created by NotebookLM. Debate Podcast: This is different from Deep Dive Podcast. This is a debate between two hosts, illuminating different perspectives on the study, “Meltwater or Warming Drives Atlantic... Continue Reading →

Seasonal outlook of hurricane activity for five North Atlantic sub-basins

Seasonal hurricane outlooks, such as those issued by NOAA's Climate Prediction Center, Colorado State University (Klotzbach et al., 2017), European Center for Medium-Range Weather Forecasts, and University of Arizona (Davis and Zeng, 2019), produce skillful (i.e.,. better than climatology) seasonal forecasts of overall North Atlantic tropical cyclone (TC) activity. Such forecasts are possible because seasonal... Continue Reading →

Synergy effect of warm Atlantic-Pacific on the longest-lasting 2023 western North American heat wave

The southwestern United States (US) and Northern Mexico experienced their longest stretch of record-breaking heat wave in the summer of 2023 from mid-June to early August, affecting over 100 million people, causing over 200 deaths, and $14.5 billion in economic loss. In Phoenix, Arizona, for example, the heat wave lasted for 31 days from 30... Continue Reading →
