Arctic heat melts Sweden's highest peak


By Sciences et Avenir with AFP 02.08.2018

Due to heat records in the Arctic, the glacier that covers the southern peak of the Kebnekaise massif lost Wednesday 1er August 2018 its highest point in Sweden.

"I have never seen so much snow melt in the southern part of this massif as this summer," Gunhild Ninis Rosqvist, professor of geography at Stockholm University, told AFP. At the head of the Tarfala research center located near the massif in the Arctic Circle, he was able to measure the height of the summit for several years as part of a research project on global warming.

Four meters less in a month

According to the researcher, the southern peak lost four meters of snow during the month of July alone. This equates to 14 centimeters per day in a month during which Sweden has observed temperature records, which have caused dozens of forest fires, even in the Arctic Circle. According to climatologist Jean Jouzel, these fires are due to global warming.

The latest measurements showed that the southern summit was 2.097 meters above sea level and was only 20 centimeters above the northern summit (2096,8 meters above sea level). However, "according to our forecasts, the southern summit will be lower than the northern summit from August 1," said Rosqvist. Last year the difference between the two peaks was two meters. "All of this happens very quickly. The consequences of this particularly hot summer will be manifested by records of snowmelt and ice in the mountains," he adds. Kebnekaise, a popular tourist destination in northern Sweden, is known for its two peaks: one in the south, covered with a glacier, the other, made of rocks, in the north. The southern summit, measured since 1880, has melted one meter per year for the past twenty years according to Stockholm University.

If carbon dioxide emissions (CO2) continue "as if nothing had happened", ocean acidification is expected to reach record levels. This is what researchers at Cardiff University (UK) say. Remember that ocean acidification occurs when atmospheric CO2 is absorbed by water. Since the beginning of the industrial era, the ocean has already absorbed some 525 billion tons of CO2.

And if emissions are to continue at the same rate as today, the concentration of CO2 in the atmosphere will reach 930 parts per million (ppm) in the year 2100, against about 400 ppm today. This is enough to change the ocean's pH from 8,1 to 2018 to only 7,8 to 2100. A considerable increase in acidity on a logarithmic scale such as pH. https://www.futura-sciences.com/sante/a ... xtor=RSS-8

What are the efforts?

Not those of automakers in any case! : Cheesy: : Cheesy: : Cheesy:

It will not please Izentrop: https://www.francetvinfo.fr/replay-jt/f ... 92197.html

Global warming: farmers, farmers ... they file a complaint against the European Union

The European Court of Justice will have to rule on the admissibility of a complaint lodged against the Union by 11 families from eight different countries. A complaint that reproaches Europe for not having sufficiently protected them against global warming.

Logic would like them to file a complaint against the whole of humanity.
And then just have to recycle, monocultures, it's not the future. I had to question myself several times in my professional career, only have to evolve instead of attacking the "welfare state". : Mrgreen: : Mrgreen:
None of them wish to receive money, but all wish to make it known that global warming is already affecting them.
Well ! it's just to change things ...
good job guys :)

The current drought in the Sahel is unprecedented since at least ... 1600 years https://www.notre-planete.info/actualit ... esse-Sahel
A Franco-Senegalese team of researchers has reconstructed the history of arid conditions of the Sahel during the last 1600 years by analyzing archaeological shells of the Saloum delta, a mangrove estuary in Senegal. These shells, of the species Senilia senilis, form their shell of calcium carbonate (CaCO3) by integrating among the oxygen atoms a part of heavy isotopes (18O) in a proportion related to that present in the water where they live. The proportion of this isotope in water varies with salinity: it increases with evaporation and decreases with the arrival of rainwater. These shells, which contain, in chemical form, information on the water balance of the region, were consumed in large quantities by the inhabitants and accumulated for centuries in the form of mounds up to 15 meters high. The researchers dated several of these piles to 14 carbon and analyzed shells of successive strata to reconstruct for the first time the multisecular variations of the African monsoon in the Sahel.

A terrible "domino effect" threatens to turn our planet into an oven
It's a disaster scenario. But a plausible scenario. Within a few years, the average temperature of the Earth could stabilize at + 4 ° C or + 5 ° C compared to the pre-industrial era, well beyond the objective of the Paris agreement on the climate (+ 2 ° C maximum), reveals a study of the journal Proceedings of the National Academy of Sciences (PNAS), published Monday 6 August 2018. https://www.sciencesetavenir.fr/nature- ... uve_126564
