17-10-2015 CERTIFICATE "CAUSES OF CLIMATE CHANGE
. On October 9, 2015, I completed the online course, via FutureLearn, and the certificate is on its way to my address. At least four hours per week were needed to study the lessons, and all the chapters in it. It was not easy. New words and concepts needed to be explained via translators on internet (the course is in English, and a lot of words are specific terms).
Anyway, I have learned a lot from the professors: Asgeir Sorteberg (l.) and Kerim Nisancioglu (r.) (lead educators), through videos and texts. Via a comment box the students could put questions, get answers, from assistant educators, and each other. In total about 6000 people had joined (so: students of all ages and with a large scale of interests. Look here
30-12-2015 NEPAL SHERPAS REBUILT NORWAY MOUNTAIN PATHS
A group of Nepalese Sherpas have spent several years reconstructing Norway's crumbling mountain paths after being recruited for their endurance and skill at high-altitude work as well as ability to carry heavy loads. (from: The Local
Also the path up to Hallingskarvet mountain, in Prestholt, in the surroundings of Multerland, has been built by these Sherpas. All needed information, links to articles and a nice video about these Norwegian mountain paths and sherpas can be found in a special "Antoinette i Norge
" google+ page post.
30-12-2015 A WALK IN THE EVENING LAND
On Sunday 27 December, I made a photo serial about a walk that started at 14:30 and ended at 15:30
These photos, and the story, are published in my photoaccount
and also in my "Antoinette i Norge
" google+ page.
30-12-2015: KRISTIAN ØVREVOLLSEIE AND THE HALLINGFELE When the "Walk in the evening land" was almost finished, I saw this on a tree:
Who was he? When home, I searched for information about this name, Kristian Øvrevollseie, on internet. I found the following text, published in Wikipedia
, in Norwegian. I translated it into English:
"Kristian Øvrevollseie (1910-1973) was a Norwegian fiddler who grew up in Hovet in Hol, and lived there all his life.
In his youth he learned playing the Hallingfele (beautiful traditional Norwegian violin) from Sevat Sataøen from Ål, Tor Grim Gard from Nes and Helleik Kvanne Berg from Hol.
Kristian Øvrevollseie was known as an expressive and terrifically good dance fiddler. In his youth rumors went around about his play, and it was said that he got table and chairs to dance. He had a tangled playing with many double stops, and he played in addition a lot of loose string. (Note: this is what google offered me, but I doubt about the right translation from Norwegian). When he was in the right mood and energy, he played easily on all four strings simultaneously. Kristian was an important inspiration for Odd Bakkerud and Magne Myhren. He had a top as a fiddler in the 1950s, but withdrew from fiddler life after 1960. He died in 1973."

31-12-2015 NORTHPOLE: +1 CELSIUS Today the temperatures on the northpole are +1 Celsius. Normally it is -25, -30.
Planet Earth is warming up, because of climate change, but the north pole experiences this climate change in a very much higher speed. The plus Celsius temperatures, measured now, are related with the storm that has created also the bad weather in USA and Iceland recently.
The only way to avoid a repeat of this too high temperature, is to reduce the amount of greenhouse gases in the atmosphere.
What is a greenhouse gas?
A greenhouse gas (sometimes abbreviated GHG) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the greenhouse effect. The primary greenhouse gases in Earth's atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and ozone. Without greenhouse gases, the average temperature of Earth's surface would be about 15 °C (27 °F) colder than the present average of 14 °C (57 °F).
In the Solar System, the atmospheres of Venus, Mars and Titan also contain gases that cause a greenhouse effect.
Human activities since the beginning of the Industrial Revolution (taken as the year 1750) have produced a 40% increase in the atmospheric concentration of carbon dioxide, from 280 ppm in 1750 to 400 ppm in 2015.
This increase has occurred despite the uptake of a large portion of the emissions by various natural "sinks" involved in the carbon cycle.
Anthropogenic carbon dioxide (CO2) emissions (i.e. emissions produced by human activities) come from combustion of carbon-based fuels, principally coal, oil, and natural gas, along with deforestation.
It has been estimated that if greenhouse gas emissions continue at the present rate, Earth's surface temperature could exceed historical values as early as 2047, with potentially harmful effects on ecosystems, biodiversity and the livelihoods of people worldwide.
What can you do?
1. To help reducing the greenhouse gases it is a huge contribution not to eat meat every day. Two days without eating meat reduces methane, a gas produced by cows. On the moment too many cows contribute to it, because of the unhealthy habit of humans to eat meat every single day.
2. Use public transport, or a bike, or go on foot.
3. When you have to wait somewhere, stop the engine of the car. Do not let it run while you have to wait for a while.
4. Start following the free online course "Causes of Climate Change
" organized by "FutureLearn" and offered by excellent professors of the University of Bergen, Norway (in English), for all levels of education, with the minimum of high school concerning answering the questions, but even just following the videos, and reading some texts is very very excellent to create some awareness in all minds. Do it!
