"There's evidence that our brains are susceptible to temperature abnormalities," says Joe Allen, associate professor and director of the Harvard Healthy Buildings program at Harvard University. And as the climate changes, Allen says, temperatures spike and heat waves are more frequent.
There's still a lot to learn about how our brains and bodies respond to heat. "We all tend to think we can compensate, we can do just fine" during heat waves says Allen. But he says the "evidence shows that the indoor temperature can have a dramatic impact on our ability to be productive and learn."
With extreme heat also comes the risk of rails warping, which can cause train derailments, rolling black outs and subsequent service disruptions, according to Nick Bassill, a meteorologist at the University of Albany who regularly works with state governments and utility companies.
During the record-breaking heatwave in the Pacific Northwest last summer, in which temperatures reached 115F, roads buckled and power cables melted. Amtrak announced delays in service during that period.
While the first half of August saw a rapid pace of Arctic sea ice loss, the pace slowed during the latter half of the month as mostly cooler conditions set in. Antarctic sea ice extent increased during the second half of the month.
As is typical during the latter half of August, the pace of ice loss slowed (Figure 1b). Nevertheless, the daily ice loss rate of 72,100 square kilometers (27,800 square miles) per day was faster than the 1981 to 2010 average of 57,200 square kilometers (22,100 square miles) per day.
The chorus reflects on the perpetual cycle of these thoughts, as the narrator confesses that they constantly think about their ex-partner, especially during "late nights in the middle of June." The mention of "heat waves" symbolizes the emotional turmoil and confusion the narrator experiences, as they struggle to accept the reality of the situation and find happiness without their former lover.
Corn and tomatoes are among many plants that commonly roll their leaves or cup in response to heat. Leaf surface area is minimized, and stomata (microscopic openings in leaves, like pores, that allow movement of moisture and gasses) close. Together, these reduce moisture loss in the plant.
Wilting occurs when low moisture in the plant creates a lack of water pressure within the plant. Common in nonwoody annuals and perennials, many plants will recover when temperatures drop. The potential for permanent damage increases with the length of time that a plant remains wilted. Plants that wilt during the hottest part of the day and recover in the evening and early morning are likely suffering from heat stress.
A heat wave will likely mean the end for many cool weather plants like cilantro, broccoli, cauliflower, lettuce and spinach. For the best quality and flavor, it may be helpful to harvest these foods when a heat wave is predicted.
While recommendations regarding the ideal timing of watering vary, deep watering is preferred over shallow watering. Morning watering is often prescribed in times of high heat, but wilted plants should be watered as soon as is reasonable to minimize the time spent in a wilted state.
Removal of leaves and branches means a new part of the canopy will be exposed to sunlight. In times of intense heat, this can lead to sunburn in leaves that were previously shaded. Trees and shrubs with sunburn in a portion of the canopy will likely recover but will be unattractive in the meantime. Stressed trees are more likely to attract damaging insects like wood-boring beetles.
Phoenix is close to breaking a record streak for consecutive days with high temperatures at or above 110 degrees, and the heat will continue to become more enduring as urbanization grows and the impacts of climate change continue.
The current heat wave is caused by an area of high pressure that has stayed over the area for several weeks that will continue to build over the weekend, leading to even higher temperatures, according to Smith. That high pressure leads to less moisture in the atmosphere.
The urban heat island effect is when the temperatures in an urban area increase due to the heat the area retains, mostly due to heat-retaining structures and ground coverings, lack of vegetation and other impacts of urbanization.
Twelve people have died from heat related causes in Maricopa county so far this year, with half of them being reported to be unhoused, according to reporting by the Arizona Republic. Those 12 are the first confirmed deaths, but there are 55 still under investigation that are suspected to have been caused by the heat.
Arizona is currently in the middle of its monsoon, which runs from June 15 through Sept. 30, however, this season has been particularly dry. According to Issac Smith, next week Arizona may start to see some of that monsoonal moisture begin to rear its head. The extreme heat is sometimes necessary to spur the moisture into action, Saffell said.
Intensity (imax, imean, ivar): imax and imean represent the highest temperature anomaly value and mean temperature anomaly during the heat wave, respectively, and ivar is the variation in the intensity of the heat wave over the duration
Influence mechanism of heat waves on the epidemic. (a) Relationship between growth rate of confirmed cases and maximum temperature anomaly. The blue dots indicate the rate of 14-day increase in cases since the heat wave. (b) Changes in population movements after heat waves. The columns represent the growth rate of population movement five days after a heat wave event. (c) The impact process of heat wave events on the epidemic.
Trends and health hazards of heat waves. (a) Prediction of the trend of heat waves in the future. The curves demonstrate the results of the multi-model ensemble, and the shadows indicate the range of 2 times the standard deviation between the models. (b) Global temperature distribution in summer 2060. (c) The impacts of heat wave on pathogenic human diseases. The bar is proportional to the number of unique pathogenic diseases. (d) Comparative analysis of West Nile virus infections in Europe. The blue and red bars represent 2021 and 2022, respectively.
Heat waves are burning through parts of the U.S., Europe, and Asia, spurring significant business risks and slowed economic output. Regions of the eastern and southern U.S. are suffering under heat domes, with temperatures in Phoenix, Arizona, reaching nearly 120 degrees Fahrenheit this week. Several hikers in national parks died of heat-related complications, and in Europe, the heat wave has shuttered tourist sites like the Parthenon and sparked wildfires in Italy and Spain. As the globe continues to warm, scientists predict these episodes of extreme heat will become more common, increasing risk burdens to businesses and dragging down economic growth. Business leaders must consider new risks to their workers, equipment, and the infrastructure they rely on, while seeking new solutions, such as novel technologies and insurance.
Heat risks range from the immediate to the less easily quantifiable. One of the most evident impacts is on human beings working in the immediate heat: Heat stroke is killing an ever-higher number of outdoor workers, and heat-related injuries are also on the rise. Researchers at Public Health England estimate that annual heat deaths in the UK will rise 257% by 2050, and a study in British Columbia found that heat-related workplace injuries requiring compensation increased by 180% year-over-year after a devastating 2021 heatwave. Beyond death or illness, heat impairs cognitive function and causes workers to move and think more slowly, reducing productivity and potentially leading to more mistakes or accidents. A study by the International Labour Organization projected that by 2030, the equivalent of more than 2% of total working hours worldwide would be lost every year, either because it is too hot to work or because workers have to work at a slower pace.
Despite the difficulty of planning for or responding to extreme heat, business leaders have options available to them to shield themselves from the risks posed by extreme heat. One of these is the growing field of heat-related insurance. However, heat insurance is expensive, and may come to follow a growing trend wherein insurance for climate-related issues is becoming prohibitively expensive or even unavailable in the most affected areas. Nonetheless, some insurers are expanding to cover new areas of heat-related risks, such as crop failures due to weather, or insurance for dairy milk output affected by heat stress.
