Standard denial argument. Ignore the scientific argument and talk about Al Gore (a politician) instead...

Prove me wrong then and take Al Gore's place.
The world needs a truth sayer hero like you now. So please, go ahead. For starters, get China to clean up all of its power stations in the next 24 hours. Mother Gaia needs a hero like you.
Bashing keys like a powerful keyboard warrior is going to change nothing.

Fat chance of me doing that if you can't even bother to read and refute the evidence presented by the OP.

What data was faked? Who proved it, when?
How can you still believe these scientists when it was proven they faked the data?
Because CO2 absorbs and re-emits infrared radiation. Because the more CO2 there is, the less heat escapes to space. Because humans are dumping billions of tons of CO2 into the atmosphere each year. Because CO2 levels are higher than they have been for at least 700,000 years. Because that has happened over the past 100 years.
Why are they so obsessed with co2?
Not really. Temperatures rose after the LIA, yes, but they leveled off for a couple of hundred years. In any case, saying that climate changes naturally does not refute human influences.
Temperature has been rising from the end of the little ice age, well before co2 has gone up or we had any part in.
I'm not being taxed, but when do you think the time would be right to do something? Last minute? After the global average temperature has increased by 2º?
There is still a lot of research to be done and it's way to early to blame humanity or tax the people.

Look at the studies that I posted, specifically these three:
Climate models are unable to replicate warming trend unless man-made CO2 is taken into account
The lower atmosphere is warming while the upper atmosphere is cooling
Solar activity and temperature show opposite trends in recent decades
These three studies can provide a basis that will show that climate change is heavily effected by humans. There is nothing that I have posted that is based on any studies by Michael Mann so please stop bringing him up as a way to try and defuse this.
My question is if the CO2 levels around ten thousand years ago was in the same 400 ppb range why is it a problem today?

The significance is that the CO2 produced from biological activity is part of the carbon cycle, it comes directly from the atmosphere and returns to it. The CO2 produced by the burning of fossil fuels comes from carbon which had been sequestered over millions upon millions of years.
Compare that to 2000 GT from biomass from organic life or +35000 GT from the oceans. Where is the significance in that?
What "norm" are you referring to?
+-50ppm higher than the norm
You mean a decline until about 100 years ago? That would be because of orbital and axial effects on insolation.
If co2 is at it's highest value for over 700.000 years, why do we see a small decline in temperature since the last ice age?
You mean in the past? That does not show that CO2 levels do not affect temperatures.
And what about the lag? What does that say to you? It clearly shows temperature isn't carbon driven.
Actually, you are wrong. We are learning a lot. A lot is being invested in alternative energy sources. Trouble is, in the US, there is a lot of political pressure (money) against that sort of thing.
We aren't doing anything, that's the problem!
A lot of research is going into exactly that. But there is no indication that we are not the primary cause of what is happening now. The Sun is not getting hotter. Our location in our orbit and the tilt of the Earth do not account for it. What has changed is the amount of CO2 in the atmosphere.
Maybe we should learn more from the past and trying to figure out why ice ages happen or what causes these abrupt changes in earths past climate.

By norm i meant average
Yes, but when there are more of them it changes things.
It's still co2, same molecules.
Not so much. Precession does not change the tilt of the axis.
So precession has a big influence?
It shows that global temperatures can affect a variety of things.
so what does it shows than?
Yeah. Well. Cosmic rays tend to be the fall back position for AGW skeptics. The trouble is, that theory tends to conflict with current data.
There is still a lot to learn from that perspective, not just solar activity but also the effect of cosmic rays.
Over what time span?
Yes, but when there are more of them it changes things.

And what's the average CO2 concentration over that period?
The Moberg data goes back 2000 years i believe.
What was the level of insolation at that time? Was the Sun putting out the same amount of energy then as it is now?
I showed you a graph with the geocarb data where co2 levels went up to 7000ppm and yet there was no temperature rise.
Ok.
solar output at that time was 4% less than it is today
co2 levels were a lot higher back then and it wasn't causing global warming. Matter of fact the earth was in a glaciation cycle during the Ordovician period.
Were you talking about the Ordovician?
