(CNN)Hot-temperature records are far outpacing cool records across the globe this year as Europe and the United States brace again for dangerous heat waves.
In the US, 92 all-time record high temperatures had been set through July 16, compared with only five all-time record low temperatures, according to data from the US National Oceanic and Atmospheric Administration. Globally, 188 all-time heat records were broken versus 18 cool records.
Studies have showed that extreme heat will increase in frequency, intensity and duration because of the climate crisis. Gabriel Vecchi, a climate scientist at Princeton University, told CNN that the hot-and-cold record imbalance is a signal of the climate crisis, and scientists have noted a trend in recent years that hot extremes are outpacing cold ones.
