Some have found the explanation !!
The heat of the Indian Ocean flew by whirlwinds towards the Atlantic at the Cape of South Africa to prevent the Gulf Stream from decreasing !!
http://ecologie.blog.lemonde.fr/2011/05 ... -au-chaud/

and the IPCC could be totally wrong !!

Given the armada of existing real mechanisms, the climate is chaotic at all times unpredictable and more and more unstable in the last 5 million years (see the curve which I copied on econologie of wikipedia)

You take a transistor, a diode, a battery, a capa, a resistance and a self and you have an unpredictable chaotic system !!!
Same with a pendulum with two arms, certain chaos !!

So the climate of the earth with billions of oscillators or pendulums coupled is unpredictable !!!


Nevertheless, there are general rules, as a region flooded too much is compensated elsewhere by a region too dry elsewhere, air having lost its humidity by the rains, on the flooded region, in a more or less long cycle !!
Almost perpetual example (thousands of years) the dry Sahara due to the equatorial rain on the equator !!!
The monsoons or el nino and el nina are other huge examples !!

Finally, it is better to overestimate the risk of flooding when building !!
Canada with its moraines and glaciation lakes of 20000 years ago is very badly placed, to look at the maps and very difficult to avoid the risk !!

France has built everywhere without thinking and therefore many cities have serious risks of severe flooding which could have been avoided if we were a little smarter !!
Examples: la Faute sur mer and Draguignan last year, close to 100 dead !!
There will be others !!

And which was tropical humid (crocodiles ...), 3 or 5 years ago !!! [or something like that - my memory is not what it used to be!]

It's go again....

And with the rate of equipment in EdF air conditioner may have even more problem to follow ...

To follow Wednesday and Thursday therefore!

No. No bp in sight.

Heat wave: expected “significant” electricity consumption but no supply risk

AFP published on June 24, 2019

The heatwave should result this week in "significant" electricity consumption in France with the use of air conditioners and fans but the supply will be assured without problem, said Monday the manager of the high voltage network, RTE.

"RTE's forecasts predict for this week a significant consumption of electricity with a potential peak of summer consumption on Thursday, June 27 at 13 p.m. with 58 MW," a spokesperson for the company told AFP. On Monday, consumption peaked at 000 MW at 55:764 p.m., RTE said.

Electricity consumption increases during periods of high heat due to the use of fans and air conditioners. RTE estimates that each degree above normal seasonal temperatures translates into an increase in consumption of 500 MW, or the equivalent of consumption by the city of Bordeaux. The network manager assures us, however, that he "will ensure the supply of electricity without difficulty during this week of heatwave".

Electricity production will indeed be "largely sufficient" to meet demand, with a total of 77 MW of production available, of which 700 MW is nuclear.

RTE estimated at the beginning of June that France should have enough electricity this summer, even in the event of a heat wave, thanks to the good availability of nuclear power and the boom in renewable energies. These forecasts are "confirmed", said Monday the spokesperson.

A spokeswoman for EDF for her part told AFP that there was "for the moment no impact envisaged" on nuclear production, that is to say no need to shutting down the reactor to comply with the authorizations for thermal discharge into watercourses.

It is especially during very cold weather that nuclear power becomes essential and there ... no cooling problem : Lol:

during this hot week ".

RTE had estimated in early June that France should have enough electricity this summer, even in the event of a heat wave, thanks to the good availability of nuclear and the development of renewable energies. These forecasts are "confirmed", said Monday the spokesperson.

Except that with the lack of water, the rivers are dropping significantly, and where the thermal discharges in the abundant rivers do not pose too many problems, it is not the same thing with a lack of 'cooling water.
Likewise, dams are only productive as much as possible, fueled by cast iron and missing rains, wind power only works with wind which in periods of high temperature is not ideal and solar panels will not produce more so. So there are only the thermal power stations they want to shut down, not for their pollution, but to justify more and more nuclear power.

Do you really think that with 2% solar and no wind, it will? Image

There are still significant, regular winds over several areas, with around 50 km / h (last night's weather) ... Even if at home, at the moment, it's flat calm.

And for air conditioning, for once the peak of demand corresponds to the peak of PV production! We are not at the 2% average.

The situation today, at 13 p.m. and a few - solar, wind and biomethane are not negligible (about 1/4 compared to nuclear); rine to do with 1 or 2% in any case:
