it's not bad, because the XXI century, until now, is 18 years gone ...

17 / 18, nice shot group, not reassuring of course. It would be interesting to know the 18 warmest year. Maybe in the 1990 years?

VIDEO. Global warming: "We are the winners", tries to reassure the mayor of the northernmost Norwegian city on the planet
Due to global warming, the people of Longyearbyen in Norway, the northernmost city on the planet, are experiencing a mild winter again this year. Some locals see it as an opportunity.

the 13 / 03 / 2018

A polar landscape, boots sinking into the snow. And yet, in Longyearbyen, it's hot for the season, at the end of February. Above 0 ° C, instead of -13 ° C, the average temperature recorded. This city of the Norwegian archipelago of Svalbard, And yet, the nearest town to the North Pole, 1 000 kilometers away, is an example of global warming. The thermometer displays temperatures above normal by several tens of degrees. Since 2002 the Arctic is warming twice as fast as the rest of the planet. This is worried, but also happy.

Kim Holmén, the international director of the Norwegian Polar Institute, observes this warming every day. “This is the fjord,” he says. “There is water everywhere now. Eight years ago it was frozen! You see the mountain there? All around it was covered in ice. sees glaciers melt by 20, 30, 40 centimeters per year… We also see changes in fish. And the polar bear: as the ice decreases, so does its habitat… we don't see any more! "

Unprecedented plants bloom on the tops due to global warming.
According to a study based on 145 years of botanical surveys, the number of species has been enriched on 87% of sites.

The "great acceleration" now touches the peaks. Under the effect of global warming, the tops of European mountains welcome new plants, indicates a study published Wednesday, April 4 in Nature (article in English).

Plants are rising more and more rapidly from the lower levels, with peaks five times more "colonized" by new varieties of plants in the last ten years than during the decade 1957-1966, shows this study of 302 sites, from the Alps. , Pyrenees, Carpathians, Svalbard (Norway), Scotland or Scandinavia.

The "great acceleration", biological, meteorological or chemical, observed since the 1950s by the scientific community under the effect of human activities, is thus "today noticeable in the most remote places on the planet: the mountain peaks ", underlines the French CNRS in a press release.

Warming particularly affects the mountains

According to this study, based on 145 years of botanical surveys, the number of species was enriched on 87% of the sites. During the 1957-66 period, a peak hosted on average 1,1 new species; in 2007-2016, it was 5,4. This migration concerns even famous plants to move slowly.

This trend is consistent with the increase in temperatures, says the team of 53 researchers, from eleven countries, which recalls that mountains undergo a particularly rapid warming. On the other hand, the study excludes the role of other factors such as nitrogen fallout from pollutants, changes in precipitation or human attendance, which are very different from one region to another.

The month of April the hottest measurement in Europe

The month of April was very hot compared to normal in France with a surplus reaching + 2,7 ° C compared to the normal 1981 / 2010, a value nevertheless lower than those of April 2007 or 2011 (see the report mapped



The heat was maintained more durably towards Central Europe. Germany had never observed such a hot month of April over the period covered by the indicator (i.e. since 1881) with a national surplus of + 4,9 ° C compared to the 1961/1990 normal (>> ). Records have also been broken in Poland, Slovenia, Croatia, Montenegro and Serbia (>>).

In general, most of the continent of Europe has undergone remarkably high values. And with an anomaly of + 2.4 ° C according to the European program Copernicus, this April 2018 has become the hottest ever observed in Europe since the beginning of the observations, breaking the records of 2000 and 2011 (+ 1.7 ° C)!

May was certainly not better ... for proof the violent storms of recent days.

Some cells swept whole regions, and I'm not talking about Alsace ...

In Belgium, last week a storm cell ... was wider than the country! (from North to south)...
Result:

Long live Belgium

Without laughing, it is necessary that nature dissipates the excess energy of climate change ... and to say that this is only the beginning of "hostilities" ...

Of course the violent storms is not new, as this impressive cell, in Belgium too:

The lightning record was ... thunderstruck if I dare say!

A month of May record

The number of lightning strikes recorded in May "is rather close" to those recorded in summer, "and again, over a very active summer," said Steven Testelin. Just in the month of May, almost 180.000 impacts have been reported throughout the country, setting a new record since the start of this 2000 statistic. The previous record date of 2009. That year, 85.000 lightning strikes hit French soil.

Antarctica melts at a faster pace and boosts rising sea levels

13th June 2018

Antarctica has lost 3.000 billion tons of ice since 1992, enough to raise the global ocean level by almost 8 millimeters and this trend has accelerated dramatically over the last five years, according to a study released Wednesday.

Before 2012, the white continent located at the South Pole lost about 76 billion tons of ice annually, calculated the 84 scientists who participated in this reference study published in Nature.

Since then, this figure has jumped to 219 billion tons a year. In other words, for the past five years, the ice has melted at a rate almost three times higher than before.

The discovery is expected to dispel the doubts that Antarctica is rapidly melting and threatening hundreds of millions of people living in low-lying coastal areas, say the study's authors.

"We now have an unequivocal picture of what is happening in Antarctica," said Eric Rignot, principal co-author of the study and researcher at NASA's Jet Propulsion Laboratory. "We consider these results as an additional alarm bell to act, in order to slow down the warming of our planet", insists the French scientist, who has studied the glaciers and the poles for 20 years.

Covered with more than 98% by permanent ice - the ice sheet - the continent island surrounded by the Southern Ocean alone accounts for 90% of the land ice and contains the largest reserve of fresh water on the planet. If all this mass of ice melted, it would raise the level of the oceans by almost 60 meters.

Until now, scientists have struggled to determine whether Antarctica had gained weight through snowfall or lost it due to melting ice or the separation of icebergs.

But more than two decades of satellite observations have provided a more complete view.

- "Alarm signal" -

More than 90% of the ice is in East Antarctica, which has remained relatively stable despite global warming.

West Antarctica, on the other hand, is much more sensitive, especially the Antarctic Peninsula where more than 6.500 square kilometers of ice have already fallen into the sea.

During the last 25 period covered by the study, almost all the ice lost was in West Antarctica.

"While there is still considerable uncertainty regarding the evolution of the East Antarctic mass, it is increasingly clear that the loss of ice in West Antarctica has accelerated," notes Kate Hendry, a scientist from the University of Bristol which did not participate in the study.

If the trend continues, Antarctica could become the main cause of rising sea levels, with thermal expansion - water taking up more space as it warms - and the melting of sea ice in Greenland and glaciers around the world.

"The data shows that the situation is getting worse every year," said Isabella Velicogna, professor at the University of California at Irvine and one of the co-authors of the study, the results of which have been praised by several scientists.

"The strength of this research is to have brought together results and methodologies from different teams around the world," said Twila Moon, scientist at the National Snow and Ice Data Center (NSIDC) in Colorado.

Policy makers now act accordingly.

“The future of Antarctica is linked to that of the rest of the planet and of human society. Steps must be taken now to slow the rate of environmental change, increase the resilience of Antarctica and reduce risk (. ..) irreversible changes ", pleads the Australian oceanographer Steve Rintoul, author of another study on Antarctica published Wednesday in Nature.

"This should be a huge wake-up call," insists Martin Siegert, professor at Imperial College London, who was not involved in the study.

The Earth overheating: many heat records were beaten in the world this week

by Brice Louvet Scieencepost 6 July 2018,

Ireland, Scotland or Canada via the Middle East ... many places in the Northern Hemisphere have seen the thermometer climb over the past week, leading to stifling temperatures.

If it is already hot in France this week, others elsewhere in the world suffer even more! The heat is responsible for at least thirty-three deaths in southern Quebec, mainly in Montreal and surrounding areas because of record temperatures. In northern Siberia, along the coast of the Arctic Ocean, analyzes showed temperatures up to 22 ° C above normal on 5 last July.

Some notable records in North America:
- Denver tied its historic high temperature record of 40,5 ° C on June 28.

- Montreal recorded its highest temperature ever recorded since 147 years, ie 36,6 ° C on July 2.

In Europe :
- Greycrook, Scotland, has tentatively set its hottest temperature ever recorded: 33,2 ° C on June 28, exceeding the previous record of 32,9 ° C set in August 2003 in that same village. In addition, Glasgow had its hottest day with 31,9 ° C.

- In Ireland, the 28 June, it was 32 ° C in Shannon, which is another record.

- In Northern Ireland, it was 29,5 ° C in Belfast (a record also).


In Eurasia:
- Tbilisi, Georgia: The 4 July, it was 40,5 ° C in the capital, his biggest record of all time.

- Yerevan, Armenia: The 2 July, it was 42 ° C, a record for this capital.

In the Middle-East :
- Quriyat, in Oman, had the world's hottest 28 last June: 42,6 ° C.

These records are in addition to a growing list of thermal milestones established over the last fifteen months:
