Your first statement is just an example of arrogance, we don't really need to discuss anything else about that.
Why...becasue you don't like to be reminded that what you believe is going to happen flies in the face of what already happened? Good argument. Clap your hands over your ears and scream LA LA LA as loud as you can so no fact can ever penetrate your brain.
As for whether I have a basis for what I have said about 400,000 years, actually I do.
You are looking at a very short term piece of time...one that only goes back about half way into the present ice age....My timeline goes back to the beginning of the present ice age and the one before that and the one before that and the one before that. Which is likely to provide a more valid insight into the climate of the earth?
The development of a species to make it to an advanced state has taken a lot of stability. Sure, there have been problems along the way, however humans were able to come out of it. Imagine if the world were throwing up situations where humans who prospered in one region were then unable to prosper and died out. Humanity simply wouldn't develop.
And you don't think dropping into an ice age constitutes a lack of stability? Humans didn't start really advancing till the onset of the holocene when the glaciers started retreating...the more they retreated the more advanced we became....had the ice age never happened, we might be 20 million years on now and in the stars instead of 20,000 or so and fretting over the non existent threat of CO2.
Why did nothing else develop like humans in the past? Probably because of a lack of stability with the Earth.
Evolution is a product of time....look at the long stable warm periods in history and compare it to the definitely unstable climatewe are living in now. Coming out of an ice age is inherently unstable...up and down up and down with the long term trend being up...look at history....temps climb to an average and then level off for millions of years.
You seem particularly unwilling to take anything from the past...why is that?
The world is maturing, getting less violent, climate is more stable, everything is becoming less of a problem, well, until we arrived.
Again...look at the long history and compare it to the recent history.....coming out of an ice age is not a stable time....it isn't till the ice age is over that the climate seems to stabilize.
If the world warms up to 60 degrees in the summer, do you think humans are just going to adapt to that? What about cows, and sheep, and pigs, our main meat food source?
The global mean is 58.6 degrees now...you are trembling and fretting over less than 2 degrees? What is wrong with you...clearly animals can adapt to changing climates as they have been doing it since life began here...what makes you think they won't continue adapt....and they have adapted to temperatures much higher than your feared 60 degrees...and if dumb animals can do it...then human beings, the most adaptable creatures to ever walk the earth will have no problem. Personally, I would be glad to see an end of very cold winter.
Not at all. You seem more intent on attacking that actually discussing this stuff.
If you read what I wrote, I said that the last 400,000 years show a stability in the climate that didn't exist before. I'm not going to repeat myself over and over and over again for you to catch up here. I'm not playing silly little games. If you want to discuss this, then do it properly.
I know that you want to look further back, and I'm not saying 'don't look back beyond 400,000 years ago', I'm saying when it comes to WHAT TO EXPECT from the climate right now, we can't be looking back beyond 400,000 years ago. Some things, like what the world was like with higher CO2 etc, you look back further, but this ISN'T what I'm talking about, so....
So I think dropping into an ice age is a lack of stability? No.
Stability isn't necessarily the same temperatures every year, every century, every millennium. Stability is that before the temperature rises and falls were much greater than the last 400,000 years. Stability is that they didn't follow a set pattern. The last 400,000 years has seen a set pattern, more or less, and through that we can see what SHOULD happen naturally.
Evolution is a product of time. However if the evolutionary process gets stopped by an extermination of all that process, then where are you? Nowhere, that's where.
As for your silly little statement about me not taking anything from the past, er.... I've posted what we believe happened for the last 400,000 years. Is that not the past? So you can top with your little jibes, it doesn't help your argument and just leads to me less likely to bother replying to you.
