The west coast of the United States is facing a powerful heat wave that began in late August and continued through September and possibly beyond.
The heat wave is affecting about 50 million people in states like Arizona, California, Idaho, Nevada, and Utah, where temperatures are expected to exceed 100 degrees and reach at least 110 degrees in some areas.

These temperatures are coming well in advance - more than a month - ahead of when they usually start creeping up, as per abc News.
The region, known for its typically cool and rainy climate, has been experiencing more uncharacteristic heat waves and wildfires in recent years.
The heat wave is also increasing the risk of heat-related illness, especially as the majority of households in the region are not equipped with central air conditioning.
Extreme heat is the deadliest natural hazard in the U.S.
More than 230 locations in the U.S. have seen the annual number of minimum mortality temperature heat days - temperatures at which the health risks also start to rise - by 21 more days on average since 1970, according to an analysis by Climate Central.
Climate change is a major factor behind the extreme heat
According to scientists, More extreme heat indicates human-caused climate change.
As greenhouse gases trap more heat in the atmosphere, the Earth's surface temperature rises, leading to more frequent and intense heat waves, as per Inside Higher Ed.
According to a report by the Intergovernmental Panel on Climate Change (IPCC), human activities have already caused about 1.1°C of global warming above pre-industrial levels, and this could reach 1.5°C in the next two decades if emissions continue at the current rate.
The report also warns that every region of the world will face more extreme weather events, such as heat waves, droughts, floods, and storms, as a result of climate change.
The IPCC report urged immediate and drastic action to reduce greenhouse gas emissions and limit global warming to 1.5°C or below, which would require reaching net zero emissions by 2050.
However, many countries are still lagging behind their commitments under the Paris Agreement, which aims to keep global warming well below 2°C above pre-industrial levels4.
How to cope with the heat wave and protect yourself
While governments and international organizations work on tackling the root causes of climate change, individuals can also take steps to cope with the heat wave and protect themselves from its harmful effects.
Some of the tips from experts include:
Stay hydrated by drinking plenty of water and avoiding alcohol and caffeine
Wear loose-fitting, light-colored clothing and a hat or sunglasses
Avoid strenuous physical activity during the hottest hours of the day
Seek shade or air-conditioned places when possible
Check on vulnerable people such as children, the elderly and pets
Know the signs and symptoms of heat-related illnesses such as heat exhaustion and heat stroke
Call 911 or seek medical attention if you or someone else shows signs of heat stroke such as confusion, dizziness, nausea, rapid heartbeat, or unconsciousness
The heat wave is expected to last for several more days in some areas, so it is important to stay alert and prepared for any changes in weather conditions.
