In "France", 35.000 years ago:

Lionesses

Did you say "warming"? Wouldn't there be a bit of exaggeration?

Ethics must change according to our knowledge. For that we need knowledge, and solid knowledge. But in terms of climate, this is not the case.
The curves of the evolution of the temperatures over the last thousand years, emanating from scientists, show enormous dispersions. You passed us one with a spectacular rise of temperatures towards 2000, I can pass you a dozen where the maximum of these last years does not exceed the medieval optimum, for example:

or this one:

What you forget to mention is that the only valid one is Michael Mann's http://www.lemonde.fr/planete/article/2 ... _3244.html
Ball is a notorious climate skeptic https://en.wikipedia.org/wiki/Timothy_Ball when at the last one we have already discussed it.

If there are more, it may be because our ancestors have exterminated them ...

150 years ago, there were still bears!

The existence of rhinoceros or lions is not necessarily related to a hot climate. The felines are spread over many latitudes, including very northern ... As for the woolly rhinoceros, no need for comments ...

I had just talked about it. This Michael Mann is this incompetent who leaves the field of scientific controversy to sue the statisticians who have demonstrated his enormous technical and methodological errors. It has already been rejected. His mistakes were so crude that the competent people saw them as deliberate cheating, which is not certain, and triggered the trials.

Since your article in The World, he has poured water under the bridges, and the credibility of Mann is seriously tainted. See for example how it deflates:
http://principia-scientific.org/breakin ... l-lawsuit/
The problem today is Trump. Because having Trump in his camp, the more the trouble to have enemies, so even the climatosceptics are moderated and in the case, make concessions.
Mann's card was "official", but "official" is not synonymous with "valid".

I do not know .. I need sources in French.

It's in the scientific consensus, it's important.

I fly over - I do not take the time to dig the subject and follow everything.

But this remark must be of interest: in the current debate on global warming, I do not think anyone really thinks that a certain life would survive.

Even if the rhythm does not seem to be of the same order of magnitude as what happened in the Mesozoic (I speak of speed of variations, which can be crucial for the adaptations of the living, and a few million years, under the pressure of selection that would represent a rising temperature, living organisms adapt in an obvious way, will they do as well when it is in hundreds of years ????).

In short, whatever the damage, perhaps colossal, a "certain life will survive" - ​​there is life in the most extreme deserts, as there is a particular form of life around the hot springs of the abyssal depths. Now, as a future, we can perhaps dream of better?

So the question is: will man survive? [implied man and the domesticated animal or plant species he needs]. Or otherwise asked: would the man have survived the Mesozoic ????

It seems to me that's what worries you.

And there is 10 000 years, the wadis of the Sahara flowed towards a sea of ​​which Lake Chad is the inheritance. The shores of these wadis were populated by rhinos, crocodiles, hippopotamuses ... The last descendants of these crocodiles still live (finally lived a few decades ago) in perennial pools of the Ennedi ...

I think we must be in bad faith to deny these great variations, including recent glaciations.

The fact remains that I think, without bothering myself with all these great "thinkers" (I recall that a "scientist" is a man like the others, that they are mistaken, that they sometimes have oversized egos, that they also run after notoriety, TV, that they are constantly hunting for funding and that they have political opinions which also lead them to get involved in its debates there; in short, men like you and me), So I think that the warming linked to the recirculation of fossil C in the form of CO² can accentuate natural cycles, or slow down drops in average temperature ... Everything seems to indicate that we are in a warming phase. And to fight to know if it is that the cause "C fossil" or if it is it AND a natural cycle seems to me vain ... Should we accentuate the phenomenon ???

And it's not Trump who is going to convince me of anything, except his stupidity, his megalomania, his basic dishonesty, that of the billionaires who have one way or another, accumulated their money on the backs of the poor, but just say they are more "brilliant" than the others ...

And no!
There were European Lions until ancient times ... Woolly Rhinoceros as mentioned Ahmed lived to Spain.
It was also not so long ago that Mammoths in Siberia (1700 BC), their remains are beautifully preserved in the permafrost.
The last European bison disappeared in the 1920 years and the Caspian tiger is extinct in the 1970 years.
Soon our grandchildren will say that the existence of giant bugs with horns or 300 kgs cats populating the African steppes was also an exaggeration ... :|

I saw some, end of 70 years, in Poland ... I think that they are always there - finally not the same, the species!
