Putting back all you snipped:
Their frequency has increased steadily, from an average of two heat
waves per year during the 1960s to six per year during the 2010s and
2020s (Figure 1).
In recent years, the average heat wave in major U.S. urban areas has
been about four days long. This is about a day longer than the average
heat wave in the 1960s (Figure 1).
The average heat wave season across the 50 cities in this indicator is
about 46 days longer now than it was in the 1960s (Figure 1). Timing can
matter, as heat waves that occur earlier in the spring or later in the
fall can catch people off-guard and increase exposure to the health
risks associated with heat waves.
Heat waves have become more intense over time. During the 1960s, the
average heat wave across the 50 cities in Figures 1 and 2 was 2.0°F
above the local 85th percentile threshold. During the 2020s, the average
heat wave has been 2.5°F above the local threshold (Figure 1).
Of the 50 metropolitan areas in this indicator, 46 experienced a
statistically significant increase in heat wave frequency between the
1960s and 2020s. Heat wave duration has increased significantly in 28 of
these locations, the length of the heat wave season in 46, and intensity
in 20 (Figure 2).
Longer-term records show that heat waves in the 1930s remain the most
severe in recorded U.S. history (Figure 3). The spike in Figure 3
reflects extreme, persistent heat waves in the Great Plains region
during a period known as the âDust Bowl.â Poor land use practices and
many years of intense drought contributed to these heat waves by
depleting soil moisture and reducing the moderating effects of
evaporation.5'
And take a look at this part:
https://www.epa.gov/climate-indicators/climate-change-indicators-heat-waves
Heat wave frequency: nearly tripled (all since the 1960s)
Duration: up by more than a third
Length of the heat wave season: nearly tripled.
Intensity: up more than 25%.
