🚨From Aug 20-23, temperatures made at least three times more likely by human-caused climate change are projected to affect ~1.4 million square miles — an area larger than all of India.

🚨From Aug. 20-23, more than 156 million people across the western and southern U.S. are forecast to experience heat strongly influenced by human-caused climate change.

🌡️Multi-day heat streaks are dangerous, worsening air quality and raising the risk of heat-related illness.

On average, 198 major U.S. cities now experience two more extreme heat streaks each year compared to the early 1970s.

Globally, July 2026 was tied with July 2024 for the warmest July ever recorded. Records have been kept since 1850.

Over the past 2 weeks, repeated storms have flooded parts of the Midwest while warm ocean waters helped fuel extreme rainfall in Hawaii.

🚨Climate change is supercharging the water cycle, fueling extreme rainfall and flooding across the U.S.🚨

A warmer atmosphere can hold more moisture, increasing the potential for heavier downpours and flash flooding. Explore four of the impacted areas:

🌀Kauai, Hawaii

#HurricaneLala tracked over ocean waters 2°F–4°F above normal. #ClimateCentral's Climate Shift Index shows this unusual warmth was more than 100x more likely due to human-caused climate change, and up to 400x in some areas.

🌡️July 2026 was the warmest month ever recorded in the contiguous U.S., with an average temperature of 76.9°F.

��The Pacific isn't the only ocean experiencing intense heat.

In fact, nearly every major ocean basin around the world is currently experiencing some form of marine heat wave.

🌊How do warmer oceans affect the types of weather we experience?

Take #TropicalStormLala, headed toward Hawaii this weekend.

#Lala is expected to bring heavy rain to the Big Island, with NOAA forecasting up to 25" of rain in some areas on the windward side.

There’s a climate connection here:

🌡️#Lala passed over Pacific waters up to 3°F warmer than average — a level of ocean warmth made 30–70x more likely due to climate change.

🌧️Warmer water adds more moisture into the air, which can fuel heavier rainfall.

138 million people across the United States will experience at least one night with a low temperature reaching a CSI Level of 3 or higher on August 13 and 14.

🚨Record-hot nights are gripping much of the U.S. this week, offering little relief from extreme daytime heat!

Human-caused climate change has made these extreme overnight temperatures at least 3x more likely across more than 60% of the contiguous United States.

[Climate Central @ClimateCentral]

According to #ClimateCentral's Climate Shift Index, CSI levels of 5 — the highest possible — are forecast for minimum temperatures across much of the contiguous U.S. through August 14.

🌡️That means human-caused climate change made this extreme heat at least 5x more likely.
