As reported in The Local, Sweden just witnessed the hottest July on record. Weather recordings and temperatures were fist documented almost 260 years ago, and in all that time, there has never been a hotter July in Sweden.

The temperatures were the worst in major city centers. These urban areas become heat islands during a heat wave, making them prone to extreme temperatures. Even with heavy rainfalls across the country during the same month, temperatures soared to unheard of levels. That has left some wondering if this will be the hottest summer on record to ever strike the country.

Just how hot was it? Reuters reported that one of the country’s nuclear reactors had to be taken offline. The Ringhals-2 nuclear reactor uses seawater to help cool the superhot temperatures that occur inside the nuclear reactor. Unfortunately, the surrounding ocean became so hot that the water was unable to cool down the nuclear reactor. Unable to cool down the reactor with seawater, officials were forced to take the reactor offline to avoid a disaster.

Sweden hasn’t been the only country in 2018 to fall victim to rising temperatures. In fact, global temperatures have skyrocketed, with countries from the United States to Japan suffering in record-setting temperatures. As covered by Axios, heat temperatures reached record levels in Los Angeles, Montreal, Death Valley, Scandinavia, Norway, plus all major continents from Asia to the Middle East and Africa.

The escalating temperatures could have severe consequences on the environment. However, scientists are also warning that soaring heatwave deaths should be anticipated by 2080.

Metro recently reported that worldwide, the impact of heatwaves on cities could be tremendous. The hardest hit parts of the world would be in tropical and subtropical regions. However, with escalating temperatures across the planet, Europe, the United States, and Australia would also suffer from unheard of temperatures.

Scientists are warning, as they have been for some time, that efforts have to be taken to reduce the ongoing climate change. Temperatures are rising rapidly across the globe, and researchers believe that the number of heatwave deaths will rise in the coming decades. Scientists pointed to agreements such as the Paris Agreement, which sets goals for reducing greenhouse gas emissions, as a potential solution to rising temperatures.
