In other words, cold-related mortality is roughly twelve times higher than heat-related mortality.
This alone challenges the common perception that warming temperatures will necessarily lead to a surge in deaths. If anything, the data suggest that cold remains the far more significant public health risk.
Even more surprising is the study’s observation that cold-related deaths have been increasing over time. Cold-related mortality has risen by approximately 9% per year since 2000 in the United States. This trend is counter to the expectation that a warming climate would reduce cold-related risks. (9)
So, take your pick, one paper says 9 to 1 while the other says 12 to 1, and two of the earlier papers reported a 20 to 1 (6) ratio and 30 to 1 ratio (1). These variations are probably due to the regions sampled. Regardless, clearly there are a multitude of cold deaths to heat deaths.
Another interesting fact: The risks of extreme weather are the number one weapon used by activists, yet the first half of 2025 of 2025 saw the smallest number of deaths related to extreme weather since records began, while the media would have you believe millions are fleeing from climate disasters.

It is a long-term trend that has seen weather fatalities plunge by over 99 percent during the last 100 years. As hydrocarbon use pulls billions out of grinding poverty, so fortunate humans can use the extra wealth to protect themselves against all the nature throws at life on Earth.
In contrast to apocalyptic sermons, at no point in human history have humans had less risk of death related to extreme weather and climate,” concludes Roger Pielke Jr. (10)
