Brace Yourselves for El Niño Likely in 2019
There is a 75-80 percent chance of an El Niño developing by February, the United Nations' World Meteorological Organization (WMO) announced Tuesday. So what exactly does that entail?
Well, the last time we had an El Niño was in 2015-2016, which caused extreme weather-related events (droughts, fires, floods and coral bleaching) around the world, pushed atmospheric concentrations of CO2 to 400 parts per million for the first time, and drove 2016 to be the hottest year in recorded history.
Although this year's forecasted El Niño is not expected to be as powerful as the one in 2015-2016, it's not to be overlooked, weather experts warned.

"It can still significantly affect rainfall and temperature patterns in many regions, with important consequences to agricultural and food security sectors, and for management of water resources and public health, and it may combine with long-term climate change to boost 2019 global temperatures," Maxx Dilley, director of WMO's Climate Prediction and Adaptation branch, said in a news release.
El Niños are naturally occurring phenomenons that happen every two to seven years. They have a major effect on global weather patterns, including spikes in temperatures.

Meteorologist and Grist columnist Eric Holthaus pointed out that El Niño could drive 2019 into becoming another unusually hot year:
"Since El Niño also works to warm the atmosphere, it's possible that 2019 could beat 2016 as the warmest year on record. As El Niño begins to set in, both October and November have been unusually warm globally, and that trend is likely to continue, according to Zeke Hausfather, a climate scientist at University of California-Berkeley. 'It's not a safe bet 2019 will beat 2016, but it will very likely be warmer than 2018," Hausfather told me.'
The WMO said the chance of a full-fledged El Niño event between December 2018 and February 2019 is estimated to be about 75-80 percent, and about 60 percent for it to continue through February to April 2019.
U.S. weather forecasters also said there's a high chance of a El Niño forming. "Sea surface temperatures in the tropical Pacific were comfortably above the threshold for El Niño in October 2018, but the atmospheric response is lagging. A deep pool of warm water is available below the surface to renew and sustain the surface anomaly, however, and forecasters estimate an 80 percent chance of a weak El Niño during Northern Hemisphere winter 2018-19," according to Climate.gov.
El Niños are not caused by climate change, but researchers have previously suggested that we could experience extreme El Niños more frequently as our planet continues to warm.
There is a weird talking point going around that temperatures have fallen dramatically in the past two years. This… https://t.co/z8nojgk2V3— Zeke Hausfather (@Zeke Hausfather)1543245360.0

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>

This story is published as part of StudentNation's "Vision 2020: Election Stories From the Next Generation" reports from young journalists that center the concerns of diverse young voters. In this project, working with Dr. Sherri Williams, we recruited young journalists from different backgrounds to develop story ideas and reporting about their peers' concerns ahead of the most important election of our lives. We'll continue publishing two stories each week over the course of September.
In the speech she gave at the People's Climate March in Washington in 2017, Jansikwe Medina-Tayac, then 15, told a crowd of thousands, "This [climate change] is not just an environmental issue. This is a race issue, this is an immigration issue, this is a feminist issue."
