What to Know About Heat Domes--and How Long They Last.

The article discusses the ongoing impact of a heat dome affecting the United States, which has led to record-high temperatures and excessive heat warnings across the country. This phenomenon, characterized by a dome of high pressure that traps heat, has persisted for over a month, with July potentially becoming the hottest month ever recorded globally. Experts note that heat waves are becoming more frequent and intense, with predictions of continued high temperatures into August, particularly in the South and Southwest. The article highlights the role of sea surface temperature anomalies in contributing to the formation of heat domes and suggests that the likelihood of such extreme heat events will increase in the coming decades due to global warming.
