Expect the unprecedented in a hotter climate.
An exceptional heat wave broke the UK's all-time heat record. The temperature at London's Heathrow Airport broke the previous record of 38.7 C. The hottest day on record is Tuesday. The UK Met Office predicts that the temperature will rise through the day. Climate change is causing heat waves to grow more intense.

Extreme events are not made by climate change. Extreme events are made more extreme by it. This can expose people to dangerous environments if they're not used to it.
The world will continue to warm, but just how much is up to us. The heat will be even hotter.
Climate change has an influence on the likelihood of temperature extremes. According to a scientist at the Met Office, the current climate in the UK could be 10 times more likely to see 40C days than under a natural climate. Even with current pledges on emissions reductions, such extremes could be taking place every 15 years in the climate of the century to come.
It's not uncommon for records to break by small amounts. The heat event in the UK showed that they will be destroyed. Records fell by as much as 10 degrees in Canada and the U.S.
"Rapid warming means we must expect extreme event records to be broken – not just by small margins but quite often by very large ones."
The director of Climate Research in the UK National Centre for Atmospheric Science said in a statement that they must expect extreme event records to be broken.
These record heat waves are happening in a world that has warmed by 1.9 F over the last 120 years. Earth scientists think the planet will warm by at least 1.5 C or 2 C this century because of the carbon emissions in the atmosphere.
According to Kristopher Karnauskas, an associate professor in the Department of Atmospheric and Oceanic Sciences at the University of Colorado Boulder, CO2 levels are rising over 200 times faster than they did before. Karnauskas told the website. The number speaks to the seriousness of the situation.
"Right now, CO2 levels are rising over 200 times faster than they did during the last deglaciation."
There are a number of ways to cut carbon emissions.
Don't be careless in the heat. The body can't cool itself down when it's hot.
In places like the UK, where the populace isn't acclimatized to triple-digit temperatures, people are more prone to heat illness, which can include heat exhaustion and heat stroke.
In this story, you can learn more about avoiding heat illness. Mike Tipton is a professor of human and applied physiology at the University of Pompey and an expert in thermoregulation.
The idea is to maximize heat loss, minimize heat gain, and minimize heat production.
"You should take fluid as you would medicine in these conditions," said Tipton.
Don't go outside in the sun. Stay in the shade.
It's a good idea to avoid activity that will make you feel hotter.
You can use a fan to blow air. Sweat is removed from the skin by air currents. Faning your head is not a good idea. The best way to fan the body is with a fan. The body can also be misted to amplify heat loss. If you're in a room that's excessively hot, fans aren't a good idea because they can potentially heat your body.
The hands should be immersed in the water. "Your hands are very strong," said Tipton.
Sweat can evaporate from the skin if you wear light clothes.

The recommendations will become more important in the future.
"These are enormous changes."
These are extreme weather events. There is no increase in flooding or heat. These are huge changes.
