Yes, very bad news, one more, because Antarctica now plays an important role, even worse if we look at this paper ... Antarctica should not melt or pose a problem for a very long time, well this is no longer the case and it goes so fast that they can hardly believe it ...
One of West Antarctica's most vulnerable glaciers appears to have been further weakened recently. Satellite images show that the ice shelf that prevents it from collapsing into the sea is breaking up faster than before. The study is published by researchers at the University of Washington and the British Antarctic Survey in the journal Science Advances.

The Pine Island Ice Shelf is important because it helps hold back this relatively unstable West Antarctic glacier. Ice shelves should not be confused with sea ice. The platforms can be up to 2 km thick (the emerged part is only one eighth of the real height) and make it possible to slow down the advance of glaciers. Sea ice is only an average of one meter tall and does not have the same protective role. Platforms do not directly contribute to sea level rise because they are already floating. On the other hand, they serve as an anchor point for the massive glaciers of Antarctica: without these platforms, the glaciers would plunge directly into the water. It is therefore indirectly that the thinning of the fringe of ice that borders the continent leads to a rise in the level of the oceans ....

For Christmas, think about offering fins, mask and snorkel, it should be able to be used in the years to come : Twisted: https://global-climat.com/2021/06/13/la ... rotectrice

when you think that all this is the fault of petrochemicals which messes up the balance of plants and animals!

This means forgetting the storage of carbon thanks to photosynthesis, shallower plowing and intercropping cover which is increasingly used, especially in conservation agriculture.
Agriculture is however made responsible in France for 18% of greenhouse gas emissions, which is a notorious untruth. Let me explain: agriculture - through the photosynthesis of plants - is the nation's primary carbon sink. Of the 14 million hectares cultivated, all species combined, agriculture captures an average of 295 MT of CO2, which represents 21 T / hectare. It is the result of photosynthesis, which combines the carbon of CO02 in the air with the hydrogen atoms of water in the soil, and thus forms the basic compounds of the architecture of any plant. it is and its reserves which migrate in the harvested seeds.

All the energy and inputs used to achieve production represent an average of 23 MT, or 1,650 tonnes of CO2 / hectare. If we add the equivalent of the greenhouse effect of nitrous oxide, the total amounts to an equivalent of 40 MT. This nitrous oxide comes mainly from the nitrification of nitrogen in organic matter or nitrogenous fertilizers. In my opinion, part of these losses would take place in the natural cycle of the decomposition of the biomass of the fallow plots. In any case, even with the inclusion of nitrous oxide, the net sum of tonnes of CO2 captured is 255 MT (295-40), which can be compared to the 165 MT sequestered by French forests. on 16 million hectares. https://www.europeanscientist.com/fr/ag ... riculture/

An extremely objective article from:
Pierre Pagesse

Pierre Pagesse was President of the LIMAGRAIN Cooperative Group, the 4th largest seed company in the world, and of WOAGRI (Movement for a World Organization for Agriculture), from its launch in December 2005 to January 2016.
He now heads the GNIS (National Interprofessional Group of Seeds and Plants), is Chairman of the Board of Directors of the "Center d'Etudes, de Formation et d'Action Paysans", an association that publishes the French magazine "Paysans", headquarters with the Steering Committee of the HCCA (High Council for Agricultural Cooperation) and the Economic Commission of the HCCA.

Say, in the long run, are you not fed up with making fun of the world ??? : Shock:

Check the data instead of always accusing without proof, mister the vigilante via azerty interposed, the king of ugly puns.

The guy is so vague, tells so much nonsense that he ends up saying at one point "in my opinion", his numbers, they come out of his hat, in short basically, we don't care what he drools, the conflict of interest is too obvious.

We understand that the truth of the facts does not interest you, as long as you can put your muddy "jokes".
Otherwise, no need to look far https://www.decodagri.fr/oui-lagricultu ... u-carbone/ which shows a positive storage balance of 30 Mt in 2018 and we can do a lot better with conservation agriculture.

Good luck faking an erection and ejaculation! Are you keeping us up to date, oops, up to date? : Mrgreen:

Ps: Izy ... your "document" comes from the ministry. To compare forests and agriculture to explain that the existence of the first compensates for the exercise of the second, it was necessary to dare. Are you really gobbling? Not if ?

I was not talking about faking an erection ... not all women experience ejaculations every time ...

So where do you dig that up and why? : Shock: : Shock: : Shock:
