'New World Record': Imperial, California Felt Rain at 119°F
Southern California is not only sweltering under extreme heat, the city of Imperial actually witnessed rainfall when it was a scorching 119 degrees Fahrenheit outside on July 24, weather experts observed.
It's pretty rare for rainfall to occur above 100 degrees Fahrenheit, Masters noted, but NOAA weather records show that at 3:53 p.m. local time, light rain started to fall and continued for four hours straight.
"Most of the rain evaporated since the humidity was only 11-15 percent during the rain event, and only a trace of precipitation was recorded in the rain gauge. Nevertheless, the July 24 rain at 119 F in Imperial sets a new record for the hottest rain in world history," Masters wrote.
The previous record for the warmest rain was set by Needles, California on Aug. 13, 2012, when rain fell at a daytime high of 118 F with a humidity of 11 percent.
Hottest rain on record: It was 119°F as raindrops fell on Imperial Valley, CA, on July 24. That's the hottest rainf… https://t.co/WTslvn1oBH— Weather Underground (@Weather Underground)1533305475.0
So what does rain on scorching hot day feel like? After ringing up a few city offices and businesses, one Imperial resident told Masters that the rain "made it difficult to breathe" and it felt hard on their heart.
Masters also broke down the science of what happened that day: "The July 24, 2018 rain in Imperial was due to a flow of moisture coming from the southeast caused by the Southwest U.S. monsoon, a seasonal influx of moisture due to the difference in temperature between the hot desert and the cooler ocean areas surrounding Mexico to the south."
Weather expert Jeff Beradelli said the hot rain report was "amazing."
"It means that not only is Earth getting hotter but also more humid. And that is the link between a changing climate and health," Beradelli tweeted.
This is an amazing stat!! Rain at 119 degrees. Hottest temp on record to produce rain. It means that not only is Ea… https://t.co/gEsylWQlvy— Jeff Berardelli (@Jeff Berardelli)1533309623.0

By 2030, almost a third of all the energy consumed in the European Union must come from renewable sources, according to binding targets agreed in 2018. Sweden is helping lead the way.
Sweden is a world leader in renewable energy consumption. Swedish Institute/World Bank
Naturally Warm<p>54% of Sweden's power comes from renewables, and is helped by its geography. With plenty of moving water and 63% forest cover, it's no surprise the <a href="https://sweden.se/nature/energy-use-in-sweden/#" target="_blank">two largest renewable power sources</a> are hydropower and biomass. And that biomass is helping support a local energy boom.</p><p>Heating is a key use of energy in a cold country like Sweden. In recent decades, as fuel oil taxes have increased, the country's power companies have turned to renewables, like biomass, to fuel local 'district heating' plants.</p><p>In Sweden these trace their <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank">origins back to 1948</a>, when a power station's excess heat was first used to heat nearby buildings: steam is <a href="https://www.sciencedirect.com/topics/engineering/district-heating-system" target="_blank">forced along a network of pipes</a> to wherever it's needed. Today, there are around 500 district heating systems across the country, from major cities to small villages, providing heat to homes and businesses.</p><p>District heating used to be fueled mainly from the <a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140" target="_blank">by-products of power plants</a>, waste-to-energy plants and industrial processes. These days, however, Sweden is bringing more renewable sources into the mix. And as a result of competition, this localized form of power is now the country's<a href="https://www.sciencedirect.com/science/article/pii/S0360544217304140#fig3" target="_blank" rel="noopener noreferrer"> home-heating market leader.</a></p>
Sweden is using smart grids to turn buildings into energy producers. Huang et al/Elsevier
Energy ‘Prosumers’<p>But Sweden doesn't stop at village-level heating solutions. Its new breed of energy-generation takes hyper-local to the next level.</p><p>One example is in the city of Ludivika where 1970s flats <a href="https://www.buildup.eu/sites/default/files/content/transforming-a-residential-building-cluster-into-electricity-prosumers-in-sweden.pdf" target="_blank">have recently been retrofitted with the latest smart energy technology</a>.</p><p>48 family apartments spread across 3 buildings have been given photovoltaic solar panels, thermal energy storage and heat pump systems. A micro energy grid connects it all, and helps charge electric cars overnight.</p><p>The result is a cluster of 'prosumer' buildings, producing rather than consuming enough power for 77% of residents' needs. With <a href="http://www.diva-portal.org/smash/get/diva2:1232060/FULLTEXT01.pdf" target="_blank" rel="noopener noreferrer">high levels of smart meter usage</a>, it's a model that looks set to spread across Sweden.</p>

Scaling Up<p>A recent development by E.ON in Hyllie, a district on the outskirts of Malmö, southern Sweden, <a href="https://www.eonenergy.com/blog/2019/February/sweden-smart-city" target="_blank">has scaled up the smart grid principle</a>. Energy generation comes from local wind, solar, biomass and waste sources.</p><p>Smart grids then balance the power, react to the weather, deploying extra power when it's colder or putting excess into battery storage when it's warm. The system is not only more efficient, but bills have fallen.</p><p>Smart energy developments like those in Hyllie, Ludivika, and renewable-driven district heating, offer a radical alternative to the centralized energy systems many countries rely on today.</p><p>The EU's leaders have a challenge: how to generate 32% of energy from renewables by 2030. Sweden offers a vision of how technology and local solutions can turn a goal into a reality.</p>
