NASA: Earth Is Warming at Rate 'Unprecedented in 1000 Years'
By Nadia Prupis
Another day, another dire warning about the global climate emergency.
The National Aeronautics and Space Administration's (NASA) top climate scientist announced Tuesday that the Earth is warming at a pace not seen in at least the past 1,000 years, making it "very unlikely" that global temperatures will stay below the 1.5 C limit agreed to in the landmark climate treaty negotiated in Paris last December.

"In the last 30 years, we've really moved into exceptional territory," Gavin Schmidt, director of NASA's Goddard Institute for Space Studies, told the Guardian. "It's unprecedented in 1,000 years. There's no period that has the trend seen in the 20th century in terms of the inclination [of temperatures]."
"Maintaining temperatures below the 1.5 C guardrail requires significant and very rapid cuts in carbon dioxide emissions or coordinated geo-engineering," he continued, referring to controversial environmental manipulations. "That is very unlikely. We are not even yet making emissions cuts commensurate with keeping warming below 2 C."

"It's the long-term trend we have to worry about though and there's no evidence it's going away and lots of reasons to think it's here to stay," Schmidt said. "There's no pause or hiatus in temperature increase. People who think this is over are viewing the world through rose-tinted spectacles. This is a chronic problem for society for the next 100 years."
Over the past century, temperatures began to rise at a rate that is 10 times faster than historical averages, according to research by NASA and the National Oceanic and Atmospheric Administration (NOAA). That means the Earth will warm up "at least" 20 times faster than historical average in the coming 100 years, NASA said.

In fact, the Guardian notes, "a NASA reconstruction shows that the pace of temperature increase over recent decades outstrips anything that has occurred since the year 500."
Meanwhile, as Common Dreams reported Monday, a group of experts gathering at the International Geological Congress in Cape Town, South Africa this week announced that human activities such as industrialization, nuclear bomb testing and increased greenhouse gas emissions causing global warming have so "profoundly altered the planet" that they have ushered in a new epoch—the Anthropocene.

More long-finned pilot whales were found stranded today on beaches in Tasmania, Australia. About 500 whales have become stranded, including at least 380 that have died, the AP reported. It is the largest mass stranding in Australia's recorded history.

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.

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>
