Hello

Winter in Quebec has not been very cold yes sometimes -25C but short-lived, and rainy days, in January and February in March often temperatures above freezing the day, summarized the climate heats up for us. Snow of course, but sticky wet snow and not the usual amount that we should receive.
On the river the ice has gone since the beginning of March, in the north normally the lake ice sets in late April, but this year in late March the edges of the lakes begin to have pools of water.
Some pictures

On March 18 the ice left on the river.

March 18
No thick snow, yet we are more than 200km in the northern forest.

March 24 even less ice

March 24 in the northern forest, the ice melts the streams flow
the edge of the lakes, the ice is eroded, it's the last outing in the north.

Ahhh André and his superb aerial photos !!

What is worrying, from my point of view, is the speed of the phenomenon of climate change, I say "of" because I am talking about local changes!

The "specialists" did not foresee that it would be so fast ...

What will it be in 20 or 50 years?

Climate: the Gulf Stream is letting go of Europe
All the Atlantic currents are weakening under the effect of climate change.

Climatologists have been announcing and dreading it for years: under the influence of climate change, most of the currents, small or large, which cross the immense Atlantic Ocean while maintaining a balance which benefits most European climates, north- Americans and Africans are changing. This is revealed by the two studies published on April 11 in the English journal Nature.

According to scientists, the currents which cross the Atlantic have never been so weak and so random since the beginning of the XNUMXth century. This phenomenon is added to the melting of the pack ice which pours millions of tons of fresh water into the sea. This not only has an influence on the Atlantic but, moreover, calls into question the circulation of water between the northern hemisphere and the southern hemisphere.

Due to the increasingly violent confrontation between bodies of water whose temperature and salinity are increasingly different, some of the warm waters reach the depths of the sea and return to the south. This disrupts the planetary circulation of water by causing what specialists call "the meridian circulation of the Atlantic reversal". Hence the increasingly noticeable changes and wanderings of an enormous water circuit which participates in the regulation or maintenance of climates.

Threats to Europe

It is for these reasons, according to the authors of the two studies, that the famous Gulf Stream which allows Western Europe to enjoy a temperate climate is weakening. The cause: this current is no longer sufficiently cooled and its salt density decreases. The anomalies had been noted for years but, explains the professor at the Polish Institute in Potsdam, Stefan Rahmstorf, who conducted one of the studies, "we now have certainties". He adds :

We have analyzed all the available sea surface temperature data sets, including data from the late XNUMXth century to the present day. The model we found in the measurements looks exactly like what is predicted by computer simulations, namely a slowdown in the Gulf Stream.

A bad new

Scientists in the second study, conducted by David Thornalley's group from the University of London College, say that over the past fifty years, the Gulf Stream and other currents as important for planetary balance have changed "from certainly during the twentieth century, with a notable decline from 1950 "and that" this evolution is most certainly linked to human factors ". David Thornalley, head of evaluation for the English team, estimates that the change in currents, particularly in the Gulf Stream, "represents a decrease of 3 million cubic meters of water per second, the equivalent of one fifteen rivers like the Amazon. And I think that is very bad news ”.

The conclusions of the studies are indeed worrying, since if the cause of the weakening of sea currents, starting with the Gulf Stream, is linked to climate change, it will also have other serious climatic consequences.

If the temperature difference between the hot and cold source decreases, the circulation engine of the gulf stream weakens, but as the average temperature of the globe increases at the same time, it means an increase in the activity of wind energy exchanges ... so episodes of strong winds.

Well this is what is happening: see the increase in frequency and especially in the size of hurricanes, shown in the image here: climate-change-co2 / fuck-you-earth-hurricane-2017-harvey-irma-jose-katia-payback-time-is-coming-t15349.html

It's party !! The next few years are going to be nice between the glaciation of northern Europe and the Covid health diktat (reinforced by the glaciation for that matter) ...! : Evil: : Evil: : Evil:

Oh a nice polar vortex that the conspirators had announced in 2013 ...

What's going on in 2020?
