Heat waves throughout the world are causing thousands of deaths and energy failures, highlighting need for next-generation cooling technology

A person is likely to experience heat stroke when spending more than a few minutes in 104ºF (40ºC). Higher humidity makes the effects of higher temperatures even more severe, as the body struggles more to cool off. In the past few weeks, several large regions of the world have experienced temperatures way above limits considered safe.

Weather agencies this week have reported heat waves averaging as high as 110ºF (43ºC) in India and Pakistan, and even worse in Texas, where the thermometers reached as high as 112ºF (44.4ºC). Mexico had the record, with 114º in the city of Monclova.

One of the results of these extremes caused by manmade climate change is the failure of energy grids, particularly in Texas, where most homes are air-conditioned. As temperatures rise, homeowners rely ever more on ACs to keep their homes in a safe range, and as they do so, they consume more energy than the grid is equipped to provide. Last week, this caused six power plants to fail.

South Asia has some of the lowest numbers of ACs per household, but is experiencing some of the highest temperatures and humidity for very long periods, while populations exposed continue to rise.

The only solution to such a crisis is to reduce energy demand, not by shutting off air conditioners, but by needing them less, thanks to improved heat management made possible next-generation heat abatement technology that can be implemented quickly and economically in regions of the world that are not equipped with air conditioners or power grids necessary to sustain them. This is the only feasible bridge solution to mitigate climate change in the short term and save the lives of those exposed to extreme heat, who are, by and large, socioeconomically disadvantage, as is often the case with the majority of the victims of climate change.
