Antarctic meteorites threatened by climate warming

Antarctica harbors numerous large meteorite concentrations at its surface, and as such, the icy continent contains an unparalleled wealth of information on our Solar System, enabling us to understand, for example, the emergence of life on Earth, and how the Moon was formed.

A study carried out by scientists from the Université Libre de Bruxelles, ETH Zurich, WSL Birmensdorf and Vrije Universiteit Brussel highlights a rapid disappearance of meteorites due to global warming, a loss with far-reaching consequences for our understanding and knowledge of extraterrestrial life.

Using artificial intelligence to combine satellite observations of the continent with climate model projections, the scientists calculate that for every tenth of a degree of increase in global air temperature, 5,100 to 12,200 meteorites are lost from the surface of the ice sheet. By 2050, about one quarter of meteorites will be lost, and this can rise to three quarters by the end of the century, depending on future greenhouse gas emissions.

Veronica Tollenaar, PhD researcher (FNRS) at the Laboratoire de Glaciologie (GLACIOL), Faculty of Science - ULB, who co-led the study explains that "even when temperatures of the ice are well below zero, the dark meteorites warm so much in the sun that they can melt the ice directly under the meteorite. Through this process, the warm meteorite creates a local depression in the ice and over time fully disappears under the surface. As atmospheric temperatures increase, the surface temperature of the ice increases, intensifying this process, since less heat from meteorites is required to locally melt the ice."

To date, it is estimated that at least 300,000 meteorites remain at the surface of the Antarctic ice sheet. The study reveals that due to the currently ongoing warming, each year about 5,000 meteorites are lost, outpacing the pace at which Antarctic meteorites are collected by a factor five.

Harry Zekollari, Department of Water and Climate (VUB) and Laboratoire de Glaciologie (ULB)who co-lead the study, urges the need for a major international effort : “To secure this invaluable extraterrestrial material, we need to intensify and coordinate the recovery of Antarctic meteorites before we lose them to climate change. In similar efforts as collecting ice cores from vanishing glaciers or sampling coral reefs before they bleach, our study identifies the loss of meteorites as an unexpected impact of climate change upon which we need to act".

Liverpool FC Women are already deep into their pre-season preparations under boss Vicky Jepson as they plot a return to the WSL. Last season’s relegation asked some serious questions about the club’s support for their women’s team but Fenway Sports Group president Mike Gordon, who has been in direct contact with Jepson over the summer, has vowed to address those issues.

A working party has been set up, with Gordon among those looking at ways in which Jepson’s team can be integrated into the club to a greater extent.

Liverpool are appointing a new full-time groundsman to look after the women’s training pitches they lease from Tranmere Rovers at the Solar Campus in Wirral. One major criticism last season was the state of the pitch they had to play on at Prenton Park, which led to them having to cancel matches and ultimately move to Chester. However, a new state-of-the-art Desso surface has since been laid by Tranmere, so similar problems are not expected for 2020-21. The Championship season for Liverpool FC Women is due to start on September 5.

Jepson’s players have also benefited from the input and advice of Klopp and Gerrard via Zoom. Klopp spoke to them about how he had endured relegation himself with Mainz but had bounced back strongly and backed them to do the same. Gerrard talked to them about how he dealt with adversity in his playing career.

Building 0verkill on Windows 10 Subsystem for Linux - 2D ASCII art deathmatch game

I'm a big fan of the Windows Subsystem for Linux. It's real Linux that runs real user-mode ELF binaries but it's all on Windows 10. It's not running in a Virtual Machine. I talk about it and some of the things you should be aware of when sharing files between files systems in this YouTube video.

WHAT IS ALL THIS LINUX ON WINDOWS STUFF? Here's a FAQ on the Bash/Windows Subsystem for Linux/Ubuntu on Windows/Snowball in Hell and some detailed Release Notes. Yes, it's real, and it's spectacular. Can't read that much text? Here's a video I did on Ubuntu on Windows 10.

You can now install not only Ubuntu from the Windows Store (make sure you run this first from a Windows PowerShell admin prompt) - "Enable-WindowsOptionalFeature -Online -FeatureName Microsoft-Windows-Subsystem-Linux"

I have set up a very shiny Linux environment on Windows 10 with lovely things like tmux and Midnight Commander. The bash/Ubuntu/WSL shell shares the same "console host" (conhost) as PowerShell and CMD.exe, so as the type adds new support for fonts, colors, ANSI, etc, every terminal gets that new feature.

I wanted to see how far this went. How Linuxy is Linux on Windows? How good is the ANSI/ASCII support in the console on Windows 10? Clearly the only real way to check this out would be to try to build 0verkill. 0verkill is a client-server 2D deathmatch-like game in ASCII art. It has both client and server and lots of cool features. Plus building it would exercise the system pretty well. It's also nearly 20 years old which is fun.

PRO TIP: Did you know that you can easily change your command prompt colors globally with the new free open source ColorTool? You can easily switch to solarized or even color-blind schemes for deuteranopia.

There's a fork of the 0verkill code at https://github.com/hackndev/0verkill so I started there. I saw that there was a ./rebuild script that uses aclocal, autoconf, configure, and make, so I needed to apt in some stuff.

sudo apt-get install build-essential autotools-dev automake sudo apt-get install libx11-dev sudo apt-get install libxpm-dev

Then I built it with ./rebuild and got a TON of warnings. Looks like this rather old code does some (now, in the modern world) questionable things with fprintf. While I can ignore the warnings, I decided to add -Wno-format-security to the CFLAGS in Makefile.in in order to focus on any larger errors I might run into.

I then rebuild again, and get a few warnings, but nothing major. Nice.

I run the server locally with ./server. This allows you to connect multiple clients, although I'll just be connecting locally, it's nice that the networking works.

$ ./server 11. 1.2018 14:01:42 Running 0verkill server version 0.16 11. 1.2018 14:01:42 Initialization. 11. 1.2018 14:01:42 Loading sprites. 11. 1.2018 14:01:42 Loading level "level1".... 11. 1.2018 14:01:42 Loading level graphics. 11. 1.2018 14:01:42 Loading level map. 11. 1.2018 14:01:42 Loading level objects. 11. 1.2018 14:01:42 Initializing socket. 11. 1.2018 14:01:42 Installing signal handlers. 11. 1.2018 14:01:42 Game started. 11. 1.2018 14:01:42 Sleep

Next, run the client in another bash/Ubuntu console window (or a tmux pane) with ./0verkill.

Awesome. Works great, scales with the window size, ASCII and color looks great.

Now I just need to find someone to play with me...

Producing more solar power in wintertime thanks to snow

07.01.19 - Installing photovoltaic panels in high mountains could significantly reduce the power deficit experienced by this renewable energy in winter, according to a joint study by the WSL Institute for Snow and Avalanche Research SLF and EPFL. The Swiss Energy Strategy 2050 reflects the decision to abandon nuclear power in the medium term. In the coming decades the reduction in the amount of available electricity will need to be made good successively by power generated from other resources. In order to avoid the additional burden on the climate that increased carbon dioxide emissions would entail, the principal candidates are renewables, namely solar and geothermal energy, and wind. Supply shortfall in wintertime The amount of electricity generated by solar energy in particular is subject to substantial seasonal fluctuations. As a general rule, in summertime PV systems generate more electricity than is needed by the market. In winter, on the other hand, a supply shortfall arises because of reduced solar radiation. There are fewer daylight hours, the sun is lower in the sky, and fog and low stratus cloud frequently impede sunshine at low altitudes in particular. In order to overcome the disparity between supply and demand, electricity produced in the summer needs to be stored for available use in wintertime. This is currently feasible on a large scale only in pumped storage power stations, but available capacities are lacking. Furthermore, this solution entails high energy wastage. For that reason, it would make better sense to generate greater amounts of solar power in winter. PV systems in high Alpine regions In a study published recently in the leading scientific journal Proceedings of the National Academy of Sciences (PNAS), Annelen Kahl and her colleagues in the snow processes research group of the WSL Institute for Snow and Avalanche Research SLF and the Laboratory of Cryospheric Sciences (CRYOS), which is affiliated to EPFL, examine whether more electrical energy could be produced in wintertime in particular by installing PV systems not on the Swiss plateau, but in high Alpine regions. Among the resources they utilised to answer this question were data captured by remote sensing satellites, which provide an estimate of solar radiation reaching the ground across the whole of Switzerland. On this basis the researchers calculated the potential for generating electricity with PV systems. This investigation now shows that PV systems installed in high Alpine regions can significantly reduce the seasonal supply shortfall in wintertime because the amount of solar radiation in winter is greater there than on the Swiss Plateau, which is often shrouded in fog. Snow raises electricity production The researchers also investigated the influence exerted by the snow-covered ground and the inclination of installed solar panels on the amount of electricity generated. Kahl explains, “When PV systems are installed in the mountains, solar radiation reflected by the snow can be used additionally to produce electricity.” According to the study, this reflected radiation is exploited most efficiently when the solar panels are installed at a steep angle. Taking this action can further increase the amount of electricity generated in wintertime. “Our study shows that PV systems in the mountains, compared with installations on the roofs of buildings in the Swiss Plateau, are much more capable of overcoming the supply shortfall that will arise as a consequence of abandoning nuclear power because, per square metre, solar panels at high altitudes produce electricity not only in larger quantities, but also when it is needed,” adds Kahl. System trials above Davos With the aid of an experimental system on the Totalp in the Parsenn ski resort above Davos, the SLF and EPFL, together with the utility company that supplies the canton of Zurich (EKZ) and the Zurich University of Applied Sciences (ZHAW), are currently examining technical and practical issues arising from the installation of PV systems in the mountains, including the angle at which the panels have to be mounted so that deposited snow slides off by itself.

Stonehenge, England

Today is a special day in the Northern Hemisphere, because it is the shortest day of the year—the winter solstice. The hours of daylight will gradually increase until we reach the summer solstice, or first day of summer in June which is the longest day of the year.

My husband and I had the opportunity to travel to England and visit the great stone circle of Stonehenge, and also to Ireland for a visit to the ancient passage tomb of Newgrange. Both sites are temples and calendars built in ancient times for pagan worship and ceremonies. They also mark the the winter solstice or rebirth of the sun.

Newgrange, Ireland

Today is also special because we will experience a Cold Moon and meteor shower. The following article explains all three phenomenon. The article was taken from WSLS Newschannel 10 of Roanoke, Virginia web site.

(CNN) – For six months now, the days have grown shorter and the nights have grown longer in the Northern Hemisphere — but that’s about to reverse itself.

Winter solstice, the shortest day of 2018, is Friday, December 21.

The solstice this year will be extra special because it will be followed the next day by a full moon known as the Cold Moon, and you might be able to see a meteor shower to boot.

First, CNN meteorologists Dave Hennen, Judson Jones and Brandon Miller help us understand the science behind the solstice.

Then we’ll take a closer look at that special moon. Finally, we’ll explore some traditions and celebrations around the world that could inspire a travel adventure:

The science behind a winter solstice

The winter solstice marks the shortest day of the year in the Northern Hemisphere, when the sun appears at its most southerly position, directly overhead at the Tropic of Capricorn. It marks the longest day of the year in the Southern Hemisphere.

When exactly does it occur?

The solstice usually takes place on December 21. The time that the solstice occurs and the day itself can shift because the solar year (the time it takes for the sun to reappear in the same spot as seen from Earth) doesn’t exactly match our calendar year.

If you want to be super-precise in your observations, the exact time of the 2018 winter solstice will be 22:23 Universal Time. That would be 5:23 p.m. ET (for parts of Canada, the United States and Latin America). The website EarthSky has a handy conversion website for your time zone. You might also try to the conversion chart at WorldTimeBuddy.

What causes the winter solstice to even happen?

Because the Earth is tilted on its rotational axis, we experience seasons here on Earth. As the Earth moves around the sun, each hemisphere experiences winter when it’s tilted away from the sun and summer when it’s tilted toward the sun.

Wait. Why is the Earth tilted?

Scientists are not entirely sure how this occurred, but they think that billions of years ago, as the solar system was taking shape, the Earth was subject to violent collisions that caused the axis to tilt.

What other seasonal transitions do we mark?

The equinoxes, both spring and fall, mark when the sun’s rays are directly over the equator, where we have equal length of day and night. The summer solstice is when the sun’s rays are farthest north over the Tropic of Cancer, giving us our longest day and summer in the Northern Hemisphere.

So what’s going on with this full moon?

Our last full moon of the year will come less than a day after the solstice. Again, for those of you who love precision, it will occur on Saturday, December 22, at 17:49 Universal Time (that’s 12:49 p.m. ET), EarthSky says.

However, when you’re looking out into a clear sky on Friday night, the moon will appear full to you — and could be so bright that people with pretty good eyesight could read by it.

Over many centuries, this moon has been called several names: Cold Moon, Cold Full Moon, Long Night Moon(by some Native American tribes) or the Moon Before Yule (from the Anglo-Saxon lunar calendar).

If you’re wondering how special this Cold Moon is so close to the solstice, it will be 2029 before it happens again. So it’s not a once-in-a-lifetime event, but still, you don’t see this too often.

Now what about that meteor shower?

The annual Ursids meteor shower is expected to peak a day or two after the solstice. You might be able to see up to 10 “shooting stars” per hour depending on your location.

The website In the Sky has a great feature that helps you figure out where to watch and how many meteors you might see. For instance, people in South Florida might expect just three per hour while people in Juneau, Alaska, might expect seven per hour.

One caveat: That Cold Moon will be so bright that it could outshine some of the meteors as they streak in, making them harder to spot.

Winter solstice traditions and celebrations

It’s no surprise many cultures and religions celebrate a holiday — whether it be Christmas, Hanukkah, Kwanzaa or pagan festivals — that coincides with the return of the sun and longer days to come.

Ancient peoples whose survival depended on a precise knowledge of seasonal cycles marked this first day of winter with elaborate ceremonies and celebrations. Spiritually, these celebrations symbolize the opportunity for renewal, a casting off of old habits and negative feelings and an embracing of hope amid darkness as the days once again begin to grow longer.

Many of the ancient symbols and ceremonies of the solstice live on today. Here are five extraordinary places to experience something magical during winter’s relentlessly long night:

UNITED KINGDOM: Cornwall and Stonehenge

Better known for pirates than the solstice, the town of Penzance on the southwest coast of England has revived a delightful array of Cornish solstice events leading up to December 21. The Montol Festival is a fun mix of pagan customs and more recent Christmas traditions that were once common throughout Cornwall.

Early in the week, join in caroling and other events. On the solstice, referred to here as Montol Eve, get your dancing card ready for the Guise, a community dance in which people dress in masks and other “topsy-turvy” disguises based on a 19th-century tradition of the rich dressing in rags while poorer citizens effected a “mock posh” look.

You can also don your finery for torchlit processions. The merrymaking only continues when the revelers disperse to pubs around town.

With some planning, it’s also possible to incorporate a trip to Stonehenge, the UK’s most famous site for solstice celebrations. On the winter solstice, visitors have the rare opportunity to enter the towering, mysterious stone circle for a sunrise ceremony run by local pagan and druid groups.

The trip from Penzance to Stonehenge takes less than four hours by car, making it entirely feasible to spend the night of December 20 in Salisbury, the nearest town to Stonehenge, and rise before dawn for the ceremony among the stones.

The Winter Solstice Stonehenge, England Today is a special day in the Northern Hemisphere, because it is the shortest day of the year—the winter solstice.
