1. 2023 US Heatwave: Record Ocean Temperatures and Devastating Impacts

In 2023, the United States experienced its longest-lasting heatwave, fueled by record warm ocean temperatures in both the Atlantic and Pacific. This extreme weather event, which lasted from mid-June to early August, affected over 100 million people and resulted in over 300 deaths. The heatwave caused significant economic losses, totaling $14.5 billion, making it the costliest North American weather and climate disaster of 2023. Cities like Phoenix, Arizona, and New Orleans, Louisiana, set new temperature records, with Phoenix experiencing 55 consecutive days of temperatures exceeding 104°F and a record nighttime minimum temperature of 97°F. Scientists from NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the University of Miami Cooperative Institute for Marine and Atmospheric Studies (CIMAS) have linked this prolonged heatwave to extremely warm sea surface temperatures in the Atlantic and a developing El Niño in the Pacific. The study, published in Nature Communications, reveals how these oceanic conditions influenced large-scale wind patterns, creating a persistent high-pressure system that exacerbated the heatwave. Understanding these interactions is crucial for improving long-range forecasts of extreme weather events and mitigating their impacts on human health, the environment, and the economy.

2. Record-Breaking Marine Heatwaves in 2023: Are Oceans Reaching a Climate Tipping Point?

Explore how 2023 witnessed the most intense, longest-lasting marine heatwaves ever recorded, affecting 96% of the world's oceans. Learn about the impact of these extreme ocean temperatures on marine ecosystems, including coral bleaching and species shifts, and how these events may indicate a climate tipping point driven by human-caused climate change and ocean-atmosphere dynamics.

In this video, we break down key findings from a recent study published in Science, using satellite data and ocean circulation models. Discover the role of El Niño in fueling ocean warming, the unprecedented 525-day heatwave in the North Atlantic, and the extensive heat in the Pacific Oceans.

Understand why marine heatwaves not only threaten biodiversity but also fisheries and economies worldwide. Stay informed about what scientists say on the future of our oceans amidst rising global temperatures and what this means for climate action.

3. 2023 Oceans Boil: Unprecedented Marine Heat Waves Explained

Discover how 2023 became a record-breaking year as marine heat waves blanketed 96% of the world's ocean surface, lasting four times longer than historical averages.

In this video, we dive into the science behind the extreme ocean warming events, exploring how weakened winds, reduced cloud cover, and shifting ocean currents contributed to dangerous temperature spikes. Learn about the profound impact on marine ecosystems, including coral bleaching, mass fish die-offs, and the economic consequences for the fishing industry.

Join us as we break down the research findings and discuss what these unprecedented events mean for our climate and the future of our oceans.
