The latest figures and weather consequences of global warming

[izentrop]

The mad race continues: we are already at + 2,5 ° C in France

It's not completely a surprise

If 2019 is the second hottest year for the entire planet, it is the first year for geographic Europe. Our geographic area has warmed by around 2 ° C since the pre-industrial period, compared to 1,1 ° C for the global average. As predicted by climatologists, global warming is felt more strongly on the continents than on the oceans and near the coasts. And more strongly in the northern hemisphere - where the land surface is more extensive than in the southern hemisphere - and in the arctic zone.

Above all, 11 of the 12 hottest years since the start of thermometric records are after the year 2000. The four hottest years are 2019, 2014, 2015 and 2018. Such a concentration of record years since the start of the 21st century is spectacular and unprecedented in climatic annals.

And without covid what would have given ???

I am obviously talking about phenomena such as urban islands ...

2020 is the hottest year on record in France

According to Météo-France, 2020 is an “extraordinary” year which gives a new sign of global warming

The reduction in CO2 emissions due to covid does not change much. Perhaps consuming less energy feels like total containment.

The overheating in the urban islands is due to the concrete and bitumen which restore the heat absorbed during the day at night.
Vegetation zones, which regulate the temperature by their perspiration, are increasingly eaten away and concreted in large cities.

 The European Commission is asking its member states to reduce its CO60 emissions by 2% by 2030. At the speed the world is going, it is impractical, even confinement does not allow this reduction. Mr. Laurent Fabius recently said that we had to fight even harder against global warming than against covid-19. Unfortunately, nothing ever happens. I posted a petition calling for an end to the use of bitumen in the manufacture of roads in France. I live near an asphalt plant, which is described by some media as a real health bomb. The use of fossil matter contributes to global warming, alternative solutions exist such as algoroutes. We must act quickly, the state must legislate in this direction ... 

Please sign the petition and share it.

It might not be much, but a butterfly flapping in Brazil can cause a tornado in Texas

... heat also due to human activity: local pollution and heat loss!

Seen at the Intermarché de Riez:
Three huge motorhomes over 3.5T with only 2 people on board for each and a trailer with a (very) big quad behind (all). Hello the carbon footprint to go do the idiots in 04, piss off everyone on the road and the paths ...

There are 20 the average temperature was 000 degrees lower than today ... (Finally seen at the end speed or the temperature increases) Glaciers reached Lyon and we could reach Great Britain and France on foot.
What will our world be like when we reach the 4 degrees announced in the years to come? Will this increase not be exceptional ??? Melting ice caps, melting permafrost .....
Will our vegetation be adapted to this climate change? Can the golf stream stop?
There is so much unknown that it is unreal that nothing is being done to combat it.
I don't have a particular political conviction, but isn't capitalism leading us to our doom?
I'm afraid for my future and even more for that of my 6-year-old son

The cold snap we are experiencing right now is believed to be due to sudden stratospheric warming in the Arctic https://www.futura-sciences.com/planete ... oid-85064/

Remember that in principle, at the onset of winter, with the days getting shorter, the northern hemisphere receives less ultraviolet rays. Temperatures are dropping. But far north, with the onset of the polar night, temperatures drop considerably. These marked differences in temperature give rise to what meteorologists call the polar night stratospheric jet stream. Circulation from west to west is very rapid around the pole inside which nestles, until spring, a very cold area called the polar vortex.
But when an SSW occurs, we observe a change in the circulation of strong winds around the polar vortex. An inversion, even. Thus the stratospheric jet stream of the polar night finds itself blowing in the opposite direction to that of the jet stream. Cold air can then get trapped in this jet stream and shift towards our latitudes. This is what happened during the intense cold episode that hit Europe in early 2018. Ditto in February 2012, for the last great cold wave that France experienced.
Richard Hall, researchers at the University of Bristol (UK), in a statement. Along with other specialists, he studied 40 SSWs that have occurred over the past 60 years. Showing that fractional events tend to be transmitted to the surface of our Earth - within days or weeks - and thus, to be associated with colder weather over Northwestern Europe and Siberia .

Even in a context of global warming, such events could occur. This means that we are increasingly going to have to be adaptable to extreme temperature ranges, ”continues Dann Mitchell, another author of the study.

Global warming is a far more serious threat than covid and a vaccine will not save us from it. States urgently need to realize the urgency of the situation. If they are not able the people must act
