Heat waves have an impact on the economy. They can reduce labour productivity, disrupt agricultural and industrial processes and damage infrastructure. [6] [7] Severe heat waves have caused catastrophic crop failures and thousands of deaths from hyperthermia. They have increased the risk of wildfires in areas with drought. They can lead to ...
World Weather Attribution is an academic collaboration studying extreme event attribution, calculations of the impact of climate change on extreme meteorological events such as heat waves, droughts, and storms. When an extreme event occurs, the project computes the likelihood that the occurrence, intensity, and duration of the event was due to ...
A number of heat waves began across parts of the northern hemisphere in April 2023, many of which are ongoing. Various heat records have been broken, [1] with July being the hottest month ever recorded. [2] Scientists have attributed the heat waves to man-made climate change. [1] [2] Another cause is the El Niño phenomena which began to ...
The extreme heat resulted in 569 deaths in Phoenix. [21] The summer heat wave resulted in Texas experiencing its second hottest summer on record in 2023, with the full year being its hottest on record. Over 300 people died from heat in Texas in 2023, the most since the state began tracking such deaths in 1989. [22]
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Heat-related deaths in people older than 65 years reached a record high of an estimated 345 000 deaths in 2019". [3]: 9 More than 70,000 Europeans died as a result of the 2003 European heat wave. [40] Also more than 2,000 people died in Karachi, Pakistan in June 2015 due to a severe heat wave with temperatures as high as 49 °C (120 °F).
The marine heatwave termed "The Blob" that occurred in the Northeastern Pacific from 2013 to 2016. [49] Research on how marine heatwaves influence atmospheric conditions is emerging. Marine heatwaves in the tropical Indian Ocean are found to result in dry conditions over the central Indian subcontinent. [50]
Beginning in March 2024, severe heat waves impacted Mexico, the Southern and Western United States, and Central America, leading to dozens of broken temperature records, [1] mass deaths of animals from several threatened species, water shortages requiring rationing, [2] increased forest fires, and over 155 deaths in Mexico with 2,567 people suffering from heat-related ailments.
