(Photo: NASA and NOAA)<p>For <a href="https://data.giss.nasa.gov/gistemp/" target="_blank">its 2020 analysis</a>, NASA gathered surface temperature measurements from more than 26,000 weather stations. This data was incorporated with data from satellites as well as sea-surface temperatures taken from ship and buoy instruments. Once tallied, NASA's data showed 2020 barely edged out 2016 has the warmest year on record, with average global temperatures 1.02°C (1.84°F) above the baseline mean (1951-1980).</p><p>In a separate analysis of the raw data, NOAA found 2020 to be slightly cooler than 2016. This distinction is the result of the different methodologies used in each—for example, NOAA uses a different baseline period (1901–2000) and does not infer temperatures in polar regions lacking observations. Together, these analyses put 2020 in a statistical dead heat with the sweltering 2016 and demonstrate the global-warming trend of the past four decades.</p><p>"The last seven years have been the warmest seven years on record, typifying the ongoing and dramatic warming trend," <a href="http://email.prnewswire.com/ls/click?upn=OXp-2BEvHp8OzhyU1j9bSWuwMvMWelqIco5RbfBrouY-2BQCsSv6FnrhBjR9xReGqV57KGOs0rVc5GKMmgs-2FJKbOzjb0sJ6yjzUvrv2w75ulYk3EUck8pSjkzYhoy5ADXO0eOcn7LDjqsHyK2gp2NRf2UysMK-2F9SN4oYUmRylQcRtSUo6-2FcYeK-2B9naUetByXNCR2gF8u_FU3lc-2FvIcVOtjb4iEuBVjFYoW0IRF5dtM-2FDfzzkhmYHO5IVgq387-2BxdHEMunBZ1-2Fy0-2BJDgXnZEYvN604G1TWJfy4M4HKnIouyasgRyWEHIYmPTiDXeFrd9FqRmsl0JQfksEElkp2ITvgyFkkivWV3GiFH7z7tl1cTZ2rNh2c-2FbCRKQxkH4-2BChgYT6uWeYOvXusiC4cDsZkEBvw7lOEdPsPq78JT8F5x5gc5cMRaRJY-2FZ8q8peaKsS7Mfc5OQ6yjyEU5YUHR4QKJ1Fn-2FDuwJ5jk4Gm28sxJZNXX9IEO-2FOHlhyRcJbl6rMWcoeJZDEd-2BM8UJ5ZY-2FYqc1DHevd1Mz-2B1fQ-3D-3D" target="_blank">Gavin Schmidt</a>, director of the NASA Goddard Institute for Space Studies, <a href="https://www.sciencedaily.com/releases/2021/01/210115103020.htm" target="_blank" rel="noopener noreferrer">said in a release</a>. "Whether one year is a record or not is not really that important—the important things are long-term trends. With these trends, and as the human impact on the climate increases, we have to expect that records will continue to be broken."</p><p>And they are. According to the analyses, 2020 was the warmest year on record for Asia and Europe, the second warmest for South America, the fourth warmest for Africa and Australia, and the tenth warmest for North America. </p><p>All told, 2020 was 1.19°C (2.14°F) above averages from the late-19<sup>th</sup> century, a period that provides a rough approximate for pre-industrial conditions. This temperature is closing in on the Paris Climate Agreement's preferred goal of <a href="https://unfccc.int/process-and-meetings/the-paris-agreement/the-paris-agreemen" target="_blank" rel="noopener noreferrer">limiting global warming to 1.5°C</a> of those pre-industrial conditions.</p>
2020's hotspot was—the Artic?<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ2MDU5My9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTYyMTA5OTU1MH0.0ZCixGwhHbjmyO6By_eaMI-cXrM2-rsPq32J-pAVWPs/img.jpg?width=980" id="34c94" class="rm-shortcode" data-rm-shortcode-id="846b12bfa65c6d1b8d0a5b0d0214e091" data-rm-shortcode-name="rebelmouse-image" data-width="1106" data-height="672" />
A map of global mean temperatures in 2020 shows an scorching year for the Arctic.
(Photo: NASA and NOAA)<p>Heatwaves have become more common all over the world, but a region that really endured the heat in 2020 was the <a href="https://nsidc.org/cryosphere/arctic-meteorology/climate_change.html#:~:text=Over%20the%20past%2030%20years,climate%20change%20in%20the%20Arctic." target="_blank">Arctic</a>.</p><p>"The big story this year is Siberia; it was a hotspot," Russell Vose, chief of the analysis and synthesis branch of NOAA's National Centers for Environmental Information, said during the briefing. "In May, some places were 18°F above the average. There was a town in Siberia […] that reported a high temperature of 104°F. If that gets verified by the World Metrological Organization, it will the first there's been a weather station in the Arctic with a temperature above 100°F."</p><p>The Arctic is warming at three times the global mean, thanks to <a href="https://nsidc.org/cryosphere/arctic-meteorology/climate_change.html#:~:text=Over%20the%20past%2030%20years,climate%20change%20in%20the%20Arctic." target="_blank">a phenomenon known as Arctic Amplification</a>. As the Arctic warms, it loses its sea ice, and this creates a feedback loop. The more Arctic sea ice loss, the more heat introduced into the oceans; the more heat introduced, the more sea ice loss. And the longer this trend continues, the more devastating the effects.</p><p>For example, since the 1980s, there's been a 50 percent decline in sea ice, and this loss has exposed more of the ocean to the sun's rays. That energy then gets trapped in the ocean as heat. As the <a href="https://www.climate.gov/news-features/understanding-climate/climate-change-ocean-heat-content" target="_blank" rel="noopener noreferrer">ocean heat content</a> rises, it threatens rising sea levels and the sustainability of natural ecosystems. In 2020 alone, 255 zeta joules of heat above the baseline were introduced into Earth's oceans. In (admittedly) dramatic terms, that's <a href="https://www.mprnews.org/story/2020/01/14/twin-cities-scientist-heat-of-5-to-6-hiroshima-atom-bombs-per-second-into-earths-oceans" target="_blank" rel="noopener noreferrer">the equivalent of introducing 5 to 6 Hiroshima atom bombs</a> worth of energy every second of every day.</p><p>Looking beyond the Arctic, the average snow cover for the Northern Hemisphere was also the lowest on record. Like the Arctic sea ices, such <a href="https://nsidc.org/cryosphere/snow/climate.html#:~:text=Snow's%20effect%20on%20climate,especially%20the%20western%20United%20States." target="_blank" rel="noopener noreferrer">snow cover</a> helps regulate Earth's surface temperatures. Its melt off in the spring and summer also provides the freshwater ecosystems rely on to survive and farmers need to grow crops, especially in <a href="https://bigthink.com/surprising-science/too-many-trees?rebelltitem=2#rebelltitem2" target="_self">the Western United States</a>.</p>
Natural disasters get a man-made bump<img type="lazy-image" data-runner-src="https://assets.rebelmouse.io/eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJpbWFnZSI6Imh0dHBzOi8vYXNzZXRzLnJibC5tcy8yNTQ2MDU5NS9vcmlnaW4uanBnIiwiZXhwaXJlc19hdCI6MTY2MjUwMjE0Mn0.R_juvxCWUw-S9RDkAobjXeMn2qMHg-XVgsOHW74Uz-s/img.jpg?width=980" id="51830" class="rm-shortcode" data-rm-shortcode-id="7b3e734e1d03eaec341dca40df0939f0" data-rm-shortcode-name="rebelmouse-image" data-width="1123" data-height="672" />
A map of 2020's billion-dollar weather and climate disasters, which totaled approximately $95 billion in losses.
(Photo: NASA and NOAA)<p>2020 was also a record-breaking year for natural disasters. In the U.S. alone, there were 22 billion-dollar disasters, the most ever recorded. Combined, they resulted in a total of $95 billion in losses. The western wildfires alone consumed more than 10 million acres and destroyed large portions of Oregon, Colorado, and California.</p><p>The year also witnessed a record-setting Atlantic Hurricane season with more than 30 named storms, 13 of which were hurricanes. Typically, the World Meteorological Organization <a href="https://www.nhc.noaa.gov/aboutnames_history.shtml#:~:text=Instead%20a%20strict%20procedure%20has,is%20repeated%20every%20sixth%20year." target="_blank">names storms</a> from an annual list of 21 selected names—one for each letter of the alphabet, minus Q, U, X, Y, and Z. For only <a href="https://www.npr.org/2020/09/18/914453403/so-2020-new-storm-forms-named-alpha-because-weve-run-out-of-letters" target="_blank" rel="noopener noreferrer">the second time in history</a>, the Organization had to resort to naming storms after Greek letters because they ran out of alphabet.</p>
For the record, there's a consensus about the record<span style="display:block;position:relative;padding-top:56.25%;" class="rm-shortcode" data-rm-shortcode-id="9bb94f5d5a58d40f03e1515f3c2e467c"><iframe type="lazy-iframe" data-runner-src="https://www.youtube.com/embed/gzksqQDI_kE?rel=0" width="100%" height="auto" frameborder="0" scrolling="no" style="position:absolute;top:0;left:0;width:100%;height:100%;"></iframe></span><p>Such records are a dramatic reminder of climate change's ongoing effect on our planet. They make for an eye-catching headline, sure. But those headlines can sometimes mask the fact that these years are part of decade-long trends, trends providing a preview of what a climate-changed world will be like. </p><p>And in case there was any question as to whether these trends were the result of natural processes or man-made conditions, Schmidt and Vose did not mince words. </p><p>As Schmidt said in the briefing: "Many, many things have caused the climate to change in the past: asteroids, wobbles in the Earth's orbit, moving continents. But when we look at the 20<sup>th</sup> century, we can see very clearly what has been happening. We know the continents have not moved very much, we know the orbit has not changed very much, we know when there were volcanoes, we know what the sun is doing, and we know what we've been doing."</p><p>He continued, "When we do an attribution by driver of climate change over the 20<sup>th</sup> century, what we find is that the overwhelming cause of the warming is the increase of greenhouse gases. When you add in all of the things humans have done, all of the trends over this period are attributable to human activity."</p><p>The data are in; the consensus is in. The only thing left is to figure out how to prevent the worst of climate change before it's too late. As bad as 2020 was, it was only a preview of what could come.<strong></strong></p>
Already 14 billion miles from the Sun, Voyager 1 is speeding away at 38,000 mph.
- Jimmy Carter was U.S. president and Elvis Presley was still alive in 1977, the year Voyager 1 was launched.
- Back in 1990, Voyager 1's last picture showed Earth as nothing more than a 'Pale Blue Dot'.
- Voyager 1 is now traversing interstellar space – here's what our solar system looks like from there.

For a practical answer to that question rather than a philosophical one, direct your gaze to Ophiuchus, an equatorial constellation also known as <em>Serpentarius</em>. </p><p><span></span>Speeding towards Rasalhague and the other stars that make up the 'Serpent-bearer' is Voyager 1, the furthest human-made object in the Universe. It's currently 14.1 billion miles (22.8 billion km) from the Sun and speeding away at roughly 38,000 mph (61,000 km/h).</p><p><span></span>That's too far to observe Voyager 1 twinkle in the night sky. But you can turn the tables and see what it sees, as it looks back at us. Via NASA's Eyes website (and app), you can <a href="https://eyes.nasa.gov/apps/orrery/#/sc_voyager_1" target="_blank">pay a virtual visit</a> to where the spacecraft is now and explore its vantage as it hurtles towards the edge of the solar system.</p><p><span></span>There's Jupiter and Saturn, so seemingly close together; and Uranus, Pluto and Neptune, their orbits farther away. At the center of it all, the Sun. Nearby, the inner planets, including Earth: so close to it that they don't even get a name-tag. Those planets and their trajectories are so familiar yet now so distant, it's enough to make you homesick by proxy!</p><p>You can click and drag your way around Voyager 1, shifting your perspective to explore the region – spotting Sedna, Halley's Comet and a few other less familiar members of our solar family.<br></p>

Where it's at: this is what the view of the solar system is from Voyager 1 as it speeds into interstellar space.
Credit: NASA's Eyes, public domain<p>Although it's still sending data back to Earth, most of Voyager 1's instruments have now been powered down, and the craft is expected to go entirely dead by 2030 at the latest; but its incredible journey isn't over. In fact, it will most likely continue long after you, I and everything we know will have disappeared. Here's how it all started.</p><p><span></span>The year is 1977. Jimmy Carter's first year as president. Elvis Presley's last year alive. Star Wars hits the big screen. On September 10, Hamida Djandoubi becomes the last person ever to be guillotined in France. Five days earlier, Voyager 1 takes off from Cape Canaveral.</p><p>Voyager 1 is a small craft, weighing barely 1,820 lb. (825.5 kg). Its most prominent feature is a 12-ft (3.7-m) wide dish antenna, for talking with Earth – when there's no straight line of communication, a Digital Tape Recorder kicks in, able to hold up to 67 MB of data for later transmission. In all, Voyager 1 carries 11 different instruments to study the heavens.<br></p>

Credit: NASA/Hulton Archive/Getty Images<p>The idea for the Voyagers, 1 and 2, grew out of the Mariner program's focus on the outer planets. The Voyagers got their own name as their field of study started to diverge towards the outer heliosphere and beyond. </p><p><span></span>The heliosphere is the 'solar bubble' created by the solar wind, i.e. the plasma emitted by the Sun. The region where solar wind slows down to below the speed of sound is called the termination shock. The heliopause is the outer limit of this bubble, where outward movement of solar plasma is nullified by interstellar plasma from the rest of the Milky Way. Beyond lies interstellar space. </p><p><span></span>The Voyagers were built to withstand the intense radiation in those far reaches of space – in part by applying a protective layer of kitchen-grade aluminum foil. </p><p>Humanity's farthest probe into the Universe was launched on September 5, 1977, confusingly 16 days <em>after</em> Voyager 2. More than 43 years later, the craft is still sending data back to Earth – but not for very much longer. Here are a few snapshots for the family album:</p><ul><li>December 19, 1977: Voyager 1 overtakes Voyager 2. Voyager 1 is travelling at a speed of 3.6 AU per year, while Voyager 2 is only going at 3.3 AU. So, Voyager 1 is constantly increasing its lead over its slower brother. </li><li>Early 1979: Voyager 1 flies by Jupiter and its moons, taking close-ups of Jupiter's Great Red Spot and spotting volcanic activity on the moon Io – the first time ever this was observed outside Earth.</li><li>Late 1980: flyby of Saturn and its moons, especially Titan. The flybys of the two gas giants gave 'gravity assists' that helped Voyager 1 continue its journey. </li><li>February 14, 1990: Voyager takes a 'Solar System Family Portrait', its final picture and the first one of the solar system from the outside. It included an image of the Earth from 6 billion km (3.7 billion mi) away, as a '<a href="https://en.wikipedia.org/wiki/Pale_Blue_Dot" target="_blank">Pale Blue Dot</a>'.</li><li>February 17, 1998: Voyager 1 reaches 69.4 AU from the Sun, overtaking Pioneer 10 and becoming the most distant spacecraft sent from Earth. </li><li>2004: Voyager 1 becomes the first craft to reach termination shock, at about 94 AU from the Sun. The Astronomic Unit (AU) is the average distance from Sun to Earth (about 93 million mi, 150 million km or 8 light minutes).</li><li>August 25, 2012: after a few months of 'cosmic purgatory' and 10 days before the 35th anniversary of its launch, Voyager 1 became the first human-made vessel to cross the heliopause, at 121 AU, thus entering interstellar space. </li><li>Soon after, Voyager 1 entered a region still under some influence of the Sun, which scientists dubbed the 'magnetic highway'. </li><li>November 28, 2017: all four of Voyager 1's trajectory correction maneuver (TCM) thrusters are used for the first time since November 1980. This will allow Voyager 1 to continue to transmit data for longer.</li><li>November 5, 2018: Voyager 2 crosses the heliopause, departing the heliosphere. Both Voyagers are now in interstellar space.</li></ul>

A fairly old idea, but a really good one, is about to hit the store shelves.
- The idea of growing food from CO2 dates back to NASA 50 years ago.
- Two companies are bringing high-quality, CO2-derived protein to market.
- CO2-based foods provide an environmentally benign way of producing the protein we need to live.

Credit: Big Think<p> The basic mechanism for deriving food from CO<sup>2</sup> involves a fairly simple closed-loop system that executes a process over and over in a cyclical manner, producing edible matter along the way. In space, astronauts produce carbon dioxide when they breathe, which is then captured by microbes, which then convert it into a carbon-rich material. The astronauts eat the material, breathe out more CO<sup>2</sup>, and on and on. On Earth, the CO<sup>2</sup> is captured from the atmosphere. </p>

Credit: NASA<p> NASA's investigation into using CO<sup>2</sup> for food production began with a 1966 report written by R. B. Jagow and R. S. Thomas and published by Ames Research Center. The nine-chapter report was called "<a href="https://ntrs.nasa.gov/citations/19670025254" target="_blank">The Closed Life-Support System</a>." Each chapter contained a proposal for growing food on long missions. </p><p> Chapter 8, written by J. F. Foster and J. H. Litchfield of the Battelle Memorial Institute in Columbus, Ohio, proposed a system that utilized a hydrogen-fixing bacteria, <em><a href="https://www.ncbi.nlm.nih.gov/pmc/articles/PMC247306/" target="_blank">Hydrogenomonas</a></em>—NASA had been experimenting with the bacteria for several years at that point—and recycled CO<sup>2</sup> in a compact, low-power, closed-loop system. The system would be able to produce edible cell matter in way that "should then be possible to maintain continuous cultures at high efficiencies for very long periods of time." </p><p> At the time, extended missions that would benefit from such a system were off in the future. </p><p> In 2019, and with its eye toward upcoming Mars missions, NASA returned to the idea, sponsoring the <a href="https://www.nasa.gov/directorates/spacetech/centennial_challenges/co2challenge/challenge-announced.html" target="_blank">CO2 Conversion Challenge</a>, "seeking novel ways to convert carbon dioxide into useful compounds." Phase 1 of the contest invited proposals for processes that could "convert carbon dioxide into glucose in order to eventually create sugar-based fuel, food, medicines, adhesives and other products." </p><p> In May 2109, NASA announced the <a href="https://www.nasa.gov/spacetech/centennial_challenges/co2challenge/winning-teams-design-systems-to-convert-carbon-dioxide-into-something-sweet.html" target="_blank">winners</a> of Phase 1. The space agency concluded acceptance of <a href="https://www.co2conversionchallenge.org/#about" target="_blank">Phase 2</a> entries on December 4, 2020.</p>

Deforestation for palm oil
Credit: whitcomberd/Adobe Stock<p> Though Air Protein's promotional materials emphasize meat substitutes that will be derived from their flour, a <a href="https://youtu.be/c8WMM_PUOj0" target="_blank">TED Talk</a> by company co-founder Lisa Dyson reveals another Air Protein product that could arguably have an even greater impact by potentially eliminating the need for palm oil and the deforestation it requires — their CO<sup>2</sup> process can produce oils.</p><p><span></span>The company has already created a citrus-like oil that can be used for fragrances, flavoring, as a biodegradable cleaner, and "even as a jet fuel." Perhaps more excitingly, the company has made another oil that's similar to palm oil. Since palm trees are the <a href="https://www.ran.org/palm_oil_fact_sheet" target="_blank">crop most responsible</a> for the decimation of the world's rain forests, an environmentally benign replacement for it would be a very big deal. Dyson also notes that their oils could substitute morally problematic coconut oil, whose harvesting has lately been reported to often involve the abuse of macaque monkeys.</p>
Putting carbon dioxide to work<p> We know we have too much of the stuff, so finding a way of utilizing at least some CO<sup>2</sup> to create foods and other products that reduce the need for destructive commercial practices is a solid win for humankind. Harkening back to its NASA origins, Dyson notes in her talk that Earth, too, is sort of a self-contained spaceship, albeit a big one. Finding new ways to productively reuse what it has to offer clearly benefits us all. </p>
Valles Marineris on Mars is 10 times longer and three times deeper than Earth's Grand Canyon.
- The HiRISE instrument aboard NASA's Mars Reconnaissance Orbiter captured high-resolution images of Valles Marineris.
- Valles Marineris stretches roughly 2,500 miles across the Martian surface, and was likely formed by geologic faulting caused by volcanic activity.
- NASA's Perseverance rover is set to land on Mars in February 2021, where it will search for signs of ancient life.

Baby universes led to black holes and dark matter, proposes a new study.
- Researchers recently used a huge telescope in Hawaii to study primordial black holes.
- These black holes might have formed in the early days from baby universes and may be responsible for dark matter.
- The study also raises the possibility that our own universe may look like a black hole to outside observers.
