It's not entirely based on CO2, it just gets the most focus. I agree though, we don't enough about our climate. However, I certainly agree that lowering emissions is prudent.
And I disagree with the prudency of lowering emissions.
We are looking at enough fresh water being added into the North Atlantic to shut down the heat transport and start cooling. If this is actually the case them more emissions not less is in order.
You have an accurate - but most important, 100% complete - record for the entire 4.5 billion year history of the earth for which to make such comparison?
If not, then this statement cannot be validated.
Do we have knowledge of every single factor - and I mean every single one - that affects climate? IOW, do we know what we don't know? As paradoxical is this may seem, it's nevertheless on point. Most scientists with even an ounce of humility will admit that the whole picture is never known. These will constantly be newly discovered aspects of the topic as we study it. But it's hubris to claim that we know that man is the sole cause, that man plays the majority role, that man has caused an unprecedented rate of change, etc. when the picture is not as clear as others want to make it.
Does man have a role in this? Yes, I believe we do. Every organism that ever existed has affected its environment to some degree. Basic ecology.
Should man clean up his act? Should pollution be a priority? Should man work towards more renewable energy systems that are affordable to the masses? Absolutely.
Is man's role has large as stated by the press, the doomsdayers, the politicians, the radical environmentalists? This scientists says not likely.
Well maybe you could produce an alternative theory as to how temperature could change this radically other than the impact of the earths orbit over million of years. CO2 has increased, temperature has increased, what external force is changing the temperature if not man?
Not brilliant, scientific fact. Earth repeatedly heats and cools throughout its entire history, it is cyclic, and geologist know this without any doubt whatsoever. What is common sense, is that this process has been taking place for billions of years.
No matter what man does, whether he ever existed or not, the earth is just leaving an ice age, one of the coldest in earth's history, and is naturally returning to its normal average temperature. And just as it has been doing for billions of year, without the presence of man, it will then proceed to get much much warmer as it approaches its normal high temperature, before the cycle repeats itself.
What is not brilliant, are those who cannot look at the entirety of earth's history and understand that there are natural forces at work which make the cooling heating cycle repeat itself for billions of years. And that there is NOTHING that we can do to stop this process, even if we did not exits, it would proceed as it always has before.
Man does have an influence, about as much as a series of large volcanic eruptions that take place throughout history. When we return to crawling around in the grass and end industrial society, we might be able to eliminate volcanoes too. But I suspect there are even more natural forces at work that will continue the heating cooling cycle that has and will continue for billions of years.
Now if you are simply worried about man not being able to inhabit the coming, unstoppable warming of the earth that always occurs, that is valid. But one must realize that we are helpless to stop the natural and inevitable. Then it would make more sense to find ways to bail this rock and inhabit other worlds in space that are more suitable to life when the earth is no longer so hospitable as it has been in this little blink of an eye of human existence...
No.... it's brilliant.... in the sarcastic ignorant way. You are essentially saying that gigatons of greenhouse gases being released annually, the greenhouse gases that haven't seen the light of day in ten to hundreds of millions of years is negligible.
It's the same tired, ignorant argument.... the Earth has warmed and cool in the past therefore man can't influence climate.
And I disagree with the prudency of lowering emissions.

I am sure there are a few billion people who would like more clean air and water.

Did you look at the geological record I posted earlier in this thread? We are not even at the average temperature in earth's history and we are just leaving one of the coldest ice ages in all of earth's history. Earth should be climbing quickly after the ice age, as it always has done so before.
And there have been periods of frequent large scale volcanic activity that produced faster spikes in temperature when man was not present. And our current temperature right now is lower than the average temperature anyway.
I am not saying that we don't have any impact, just to be clear. I am saying that our impact is nothing more than extreme volcanic activity that has occurred in the distant past.
I am saying that no matter what we do, even if we became extinct and our entire civilization disappeared today, the earth would get much much warmer and return to the high temperature before the earth is once again plunged into the next ice age. As it has done over and over and over again for billions of years.
So if people want to keep mother earth a static point of just leaving the ice age, or the state of air-conditioned earth , it cannot be done. It is fantasy. That is not how the earth operates. There is no steady temperature period in the entire history of the earth, and never will be.
If we "need" a place to live with a static temperature, we will have to find that place in space. Earth is not that place.

Yea nothing you said disproves climate change. Extreme volcanic events causes climate change.

? The geologic record shows that climate change is normal and that what is occurring now has occurred many many times in Earth's history. Geology proves that climate change, rather the cycle between "tropical earth" and "ice ages", has and will always proceed as it always has. There is no need to "disprove" climate change. It is proven that it always occurs and that there has never been a period of static temperature, ever. The earth is just leaving one of the coldest ice ages in earth's history and the temperature will climb until we reach the normal high of "tropical earth", before again reversing direction and plunging into the next ice age. This will all occur whether mankind exists or not. It has been occurring for billions of years and will continue for several more billions of years until the Sun swells and vaporizes the Earth.
If you want the temperatures to remain static, you are delusional. It won't and cannot occur. So, we as a species are faced with two possible choices. Adapt to the inevitable and unstoppable warming that always occurs or find another planet in space to inhabit which is at the temperature that you find the "right" temperature...
? The geologic record shows that climate change is normal and that what is occurring now has occurred many many times in Earth's history. .
The scientist are not disputing the Earths warming and cooling cycles the Question is man causing an abnormal spike in Earths temperature due to his use of 100 million barrels a day of fossil fuels thereby creating an abnormal greenhouse effect.

Look at the geological record over billions of years that I posted earlier in this thread. The "warming" occurring now is nothing at all unnatural. Temperature acceleration has been significantly higher at other times in Earth's history after other ice ages. Temperature increases should have positive acceleration until at least the "median" temperature is reached and then start to decelerate while approaching the normal high temperatures. Which then halts and reverses direction and begins accelerating (in this case decreasing) towards the next ice age.
The current "slope" of warming is NOT at all unexpected when compared to previous times after emerging from earlier ice ages...it just isn't. It IS significant to humans only in terms of the time period of human existence. Which is not any significant time period in comparison to the Earth.

None of that is relevant. Either you are claiming that mankind has no influence on climate or not. Which is it?

Completely static? Of course not, but if we can prevent a marked and abrupt increase then we should do so. Prevention is always cheaper.
