How do we Know Human are Causing Climate Change?

[ding]

Fine, but we weren't experiencing a warming trend prior to the Industrial Revolution and the warming rate since then exceeds by 5-8 fold the fastest warming or cooling rates seen in the past 3 million years. And, of course, these warming and cooling phases have CAUSES and the ONLY cause for warming since the Industrial Revolution has been the greenhouse effect acting on human CO2 emissions.

Correct, the planet was coming out of cold spell. Just proves my point.

You know you can't prove that.

No
15,000-9000 years ago was coming out of a cold point GRADUALLY/NATURALLY.,
150 years ago is a Anomalous SPIKE Cause by Humans.
you are a raging Liar and and you know you are fULL OF SHlT.

He is and does. Many try, but none work harder at being kept on ignore.

The geologic record is littered with examples of exactly these kind of events. Climate fluctuates. Especially over the past 3 million years.

Show us some "examples of exactly these kind of events".

See the saw tooth behavior in glacial and interglacial periods?

You win. All the warming since 1850 is just one of those little sawtooths.

 

[ding]

Yes. Climate fluctuations and environmental uncertainty are hallmarks of our bipolar glaciated planet. Ask me why. I double dog dare you.

Why?

Yep, exactly as every other millennium

 

[Crick]

Why? You double dog dared me. I expected a little quicker response. Did the boss catch you surfing on company time?

Correct, the planet was coming out of cold spell. Just proves my point.

The planet came out of the cold spell about 20,000 years ago.
That is when the glaciers disappeared, the Sahara swamp turned into a desert, etc.
We are supposed to be in the start of the cooling phase, according to the last 12 ice age and warming cycles recorded on Antarctic ice cores.

But instead of letting the planet cool back off naturally, we are artificially adding an additional warming, on top the already warmest part of the natural cycle.
That will result in a double warming, that has not happened in over 70 million years.

 

[Rigby5]

the warming rate since then exceeds by 5-8 fold the fastest warming or cooling rates seen in the past 3 million years.

You know you can't prove that.

Easily proven.
The normal cooling/warming cycle is about 110k years long.
We accelerated that into less than 100 years.

 

[Rigby5]

Wrong.
They are very regular normally, about 110k year long cycle of warm and cold.
This is not at all like anything that ever happened before.
We totally changed the climate from cooling to warming in less than 50 years.

Not all glaciers disappeared

And?

 

[Rigby5]

That is the 110k long normal cycle.
There are approximately 12 of them that have been identified.
The current warming is NOTHING at all like that, and is at least 10 times faster, and is compounding a new artificial warming on top of almost the warmest natural warming.
