Global Warming Denial: Is there a good argument?

[juvenissun]

Well, I dont care.

Then I don't know how to answer.

Then I don't know how to answer.

You dont know if you are a YEC? Thats hilarious.

 

[juvenissun]

They have. The equation utilizes the radiative forcing, so you can look at other greenhouse gases like methane for instance.

Also remember H2O is a greenhouse gas, but the key here is that water concentration in the atmosphere can easily be shifted through the hydrologic cycle (you may have heard the word "precipitation", things like rain and snow). So when excess H2O is in the atmosphere it can re-equilibrate very quickly. UNLIKE excess CO2 or even excess methane.

Normally scientists characterize water as a "feedback" rather than a forcing because it can and does respond to changes in the system quickly.



It is understandable if one doesn't have experience as a scientist to be overwhelmed by the information. You can choose whatever you like, but it won't make you correct. It doesn't really sound like you are particularly familiar with the details of this topic, not everyone is. So go ahead and have your opinion as you like, but remember you should probably be familiar with the actual science before you form an opinion on it.

I am not a climate expert. I only judge by commonly available geological information. But, I think that is probably enough. When I see special data, I can recognize it.

You do not know what you are asking. That is more so.

Its either yes or no. Not much else to say. If you want to explain your position in greater detail, knock yourself out.

 

[juvenissun]

It's not exactly hard to find. Just google "atmospheric co2 levels in ice cores"

CO2 Ice Core Data

That record is only 1000 years old. I need one 30000 ago.

Go away.

 

[VirOptimus]

Go away.

How about, no.

 

[juvenissun]

30k years ago?
Wasn't that about the last time a big ice age started?

it was the last interglacial peak.

Well thankfully there's a lot of geologic data in support of anthropogenic climate change. It's a great place to start. We know how the earth's climate has changed in the past and we understand a lot of the forcing functions (not all warming is just due to CO2 releases).

That allows us to understand that the MODERN warming we see is likely BEST accounted for by the human activities which not only include release of CO2 but other greenhouse gases as well as changes in land-use which affect the climate as well.

 

[juvenissun]

It would take three Mount St. Helens [like in the 80s] and one Mount Pinatubo [like in 1991] eruption every day to equal the amount that humanity is presently emitting.

How Much CO2 Does A Single Volcano Emit?

And you even said that "just a few" eruption would equal ALL we have EVER released into the air.

Laughable really.

Assume you are right, then how did we get enough CO2 for previous periods of global warming? Of course, you do not know. But that also says what you quote may have problem.

First, geological and anthropological ARE different.
Second, I am only against the CO2 model of global warming. There are other ways to make the earth warm up very fast. Think about the sharp boundary zone of glacial-interglacial change. It is absolutely NOT caused by rising CO2 on the earth.

You can learn some geology, many colleges have classes available. Not all previous climate changes are due to CO2!

Take the recent several ice ages (The Cenozoic ice ages). They are largely caused by Milankovich Cycles which relate to the orbital obliquity of the earth about the sun.

In some cases climate change has occured because of changes in ocean circulation due to the position of the continents (tectonic plates move around on the globe, this is called PLATE TECTONICS.)

Sometimes, indeed, there are massive outgassing events that happen quickly like the SIberian Traps which may have been part of the End-Permian climate change and extinction event.

It's much more complex than you will find just reading Golden Books copies of "My First Geology Book".

...and?

So, anthological argument cannot be used on geological features. We do not editing CO2 30000 years ago, but there was a same degree of global warming then.

Why not? If we are releasing a known greenhouse gas at levels previously unimaginable and at rates that are nearly unheard of, why would it behave any differently from other sources of CO2? We are just more efficient and effective at our impact.

-sigh-. Learn about Milankovich Cycles. As has been pointed out to you many, many times now not all climate change is due to CO2 alone. Please, understand that the earth is a much more complex system than you might have learned in your junior high school earth science class.

If you want to debate the topic it is best to learn some of the basics of the topic.

Oh my.

Indeed.

It takes TIME. And we do not have the time.
