High Temperature at Death Valley

Part of: GS Paper – I Physical Geography

Context: Recently, Death Valley (USA) registered a temperature of 54.4°C which, once verified, could be the highest temperature in more than a century. The temperature was recorded at the USA National Weather Service’s automated weather station at Furnace Creek on 16th August 2020.

Background:

  • The temperature has been termed as preliminary and not final as it awaits verification.
  • According to the World Meteorological Organization (WMO), Death Valley’s all-time record high is 56.7°C taken on 10th July 1913 at Greenland Ranch.
  • It still stands as the hottest ever recorded on the planet’s surface.
  • However, since the temperature-recording mechanisms a century ago were not as advanced, many have doubted if that reading was reliable.

Effects of Extreme Heat:

  • According to the World Health Organization (WHO), extreme heat can exacerbate pre-existing health conditions, including respiratory diseases, heart conditions and kidney disorders.
  • The immediate effects on the human body are heat cramps, dehydration and even potentially fatal heat strokes.
  • It can also have a severe impact on agriculture and forests.
  • It either causes vegetables to wilt and die or encourage the spread of plant diseases.
  • It causes wildfires which lead to forest cover reduction and death of fauna.
  • It affects infrastructure too by straining power grids and causing blackouts. It can ground planes, melt roads and cause the inside of vehicles to overheat to dangerous levels.
