My point!

Lots of things cause the temperate to change.

CO2 doesn't appear to be a significant player.

Where I am seated, here in SE Michigan, glaciers extended straight up more than a mile.

That's a lot of ****ing ice!

It was also less than 18,000 years ago - a blink of an eye in geological time.

So, what caused that ice to melt?

There are many very good books on your question. I suggest reading one. The issue is long settled in the science community, no point in rehashing old news at this point.

Some might be. I suspect some posters work in the oil and gas industry and they feel their livelihoods are threatened if we all acknowledge climate change is real and we have to take action to address it. So they go online and push the denier agenda, hoping to buy more time and another paycheck before we come to our senses and realize that most oil, gas and coal needs to be left underground where it's meant to be.

The answer is at your finger tips...google...

Ice cores from both Antarctica and Greenland show that the last ice age started to become milder 19.000 years ago, completely in accordance with increased solar radiation from the earth’s favourable orientation in its orbit around the sun.

It takes circa 10.000 years for an ice age to gradually come to an end

These are not equivalent comparisons, but I suppose if you want to play that game then I can refer you to this map that shows the temperature anomalies for July:



Here is the Alaskan climate summary for July: http://akclimate.org/sites/Default/F...ly_summary.pdf

This is NOT normal. How is this so difficult to understand?
Those are data points, NOT proof.

If every bit of artic sea ice melted, how much would sea level rise? The answer is not at all because the ice is floating on water and if melted would take up the same volume as the ice. Is that enough proof?

I see the issue. If ice melts in the arctic, why not in Greenland or Antarctica.

Plus, you get the problem of the color of the polar area going from white to a darker color.

Sea level rise is far more due to the rise in temperature of the ocean than the melting of ice. The ocean expands in volume and since it is constrained on the sides and bottom, it can only go up.

Good grief, do you think I did not know that? The point of my post was this question "what melts ice" The answer is heat...More ice is melting each year and the northwest passage is now open again....

A better question for you is...If all the ice in Greenland melted how much would sea level rise?

Maybe you should read this... https://www.politifact.com/facebook-...ents-icebergs/

It's pretty well documented how much fossil fuels we burn. And the laws of chemistry are irrefutable - burning them makes CO2. There is also irrefutable proof that CO2 is a greenhouse gas.
What percentage of total yearly CO2 emissions is from human activity, vs natural occurrences?
