California has experienced the hottest month on record, and things will only get worse.
This is not only the hottest July in California history, but also the hottest month in the state history. According to a new report released by the National Oceanic and Atmospheric Administration (NOAA) on Wednesday (August 15),
Temperatures in all parts of the United States are also higher than usual. The average temperature in the lower 48 states rose to 75.5 degrees Fahrenheit (24.2 degrees Celsius). Scientists from the National Oceanic and Atmospheric Administration (NOAA) reported at a news conference that this month became the hottest July 1 1 on record in the United States, because the temperature was 1.9 degrees Fahrenheit higher than the average temperature in the 20th century. According to reports, in fact, the three months from May to July are by far the hottest period in the United States. During this period, the average temperature reached 70.9 degrees Fahrenheit (2 1.6 degrees Celsius), breaking the record of 70.6 degrees Fahrenheit (2 1.4 degrees Celsius) set by 1934.
Death Valley is hotter. The scorching desert experienced the hottest month observed anywhere on earth, with an average temperature of 108. 1 Fahrenheit (42.3 degrees Celsius). Drought and hot weather baked the western states, setting the stage for devastating fires, especially in Colorado and California. Many fires lasted until August, and hundreds of thousands of acres of land have been burned so far.
In July, more than one third of the United States suffered from drought-34.1%,up from 29.7% at the beginning of this month. In Hawaii alone, drought has spread to 30% of the state. However, the humidity in Pennsylvania has reached a record level. Timothy brown, director of the National Oceanic and Atmospheric Administration's Western Climate Center, said that it was the wettest July on record in Pennsylvania, because the rainfall reached 1.76% of the average rainfall.
It was announced at the press conference that the warm and dry climate is expected to last until June165438+1October, and piles of dry bushes in western states may keep the fire burning in autumn. Brown explained that a climate trend that has emerged in recent decades may also aggravate wildfires; At night, the temperature is still high and the humidity is reduced, which makes the dead vegetation burn more easily, resulting in a longer fire duration and more smoke. I don't see much comfort. It is reported that by June 5438+065438+ 10, the seasonal temperature in most parts of the United States may remain above the normal level, although the precipitation in the southwest is expected to be higher than the average level.
