Hot Earth Summer
It’s not your imagination. The summer of 2026 has brought historic, record-breaking, heat worldwide. To summarize:
- Multiple “heat dome” events across North America, leading to heat warnings, cancelled events across the US during July, and stress on the energy grid as families, businesses, and municipalities all strained to cope with the heat and related extreme storms and flooding.
- An earlier, longer, and more intense wildfire season in the US and Canada. So far in 2026, firefighters have responded to 48,960 wildfires that have burned more than 7.2 million acres across the United States, 129% of the 10-year average for fires and 169% for acres burned, and many are still burning. The smoke from all of these fires impacted air quality as far as 4000 miles away from the sources, causing health alerts in many locations. (Source: nifc.gov)
- Across Europe, which is warming twice as fast as the rest of the earth, similar impacts from a sweltering summer have resulted in cancelled plans and calls for massive investment in cooling and adaptation over the next 10 years. In the UK, most hospitals are not air-conditioned and will require major retrofits to accommodate hotter summers.
- And finally, the numbers don’t lie. July was the hottest month ever recorded in the United States since recordkeeping began in 1895. (Source: NOAA)
What does this mean? First, this is not an anomaly, but a trend, and worldwide recognition is dawning that adaptation will be critical in the coming decades. Bloomberg estimates that heat as a risk factor is likely to require up to 70 billion Euros in investment to address infrastructure needs and provide structural relief.
Insurers have taken note and are reckoning with the impacts of heat on business operations, as well as re-assessing risk profiles for companies subject to heat and climate-related extreme weather disruptions. Companies will be grilled on resiliency and disaster planning more vigorously than in the past during renewals and contract negotiations.
Finally, we will see more investment in and success with innovative approaches to cooling our daily activities. In Paris, a new technology successfully cools hot buildings by pumping water from the Seine through a closed-loop pipe system before returning the water to the river.

More green spaces, more regulations governing worker safety and treatment, more collaboration: all these are growing tends as we grapple with our rapidly warming home, Earth.
