The Third US National Climate Assessment confirms these trends, finding that, “Prolonged periods of high temperatures and the persistence of high nighttime temperatures have increased in many locations (especially in urban areas) over the past half century.” By the middle of this century, people in the US can expect a fourfold to sixfold increase in the number of days exceeding 95°F (35°C) under the IPCC’s A2 emissions scenario.
