You're right that human existence is just a blip in geologic time scales. A million years from now nobody will even remember global warming of this era. Probably not even a thousand years from now.

Al Gore flies on private jets! Man what a hypocrite, guess that gives me carte blanche to do as I please because some non-scientist politician whom I happen to disagree with on political matters is also emitting carbon, which doesn't affect anything by the way.

How lazy. How pathetic.

Reevaluate your priorities.
You’re right. Now is a good time to burn my trash. That is my priority at the moment.

Consquentiality is subjective and relative to perspective. From the perspective of a multi billion year old planet, yep - pretty inconsequential. From the perspective of a member of the species being described it matters just a lil bit more. Your point that if we take it too far we will destroy ourselves and the earth will shake it off in the long run is true. Not super comforting when you are a member of the species getting shaken off.

From the perspective of the universe our entire Galaxy might as well be a spec of dust. From the perspective of a bacteria our bodies may be equivalent to a planet in and of themselves. Understanding the correct perspective that has relevance to the topic at hand is a vital part of reading comprehension.

4. The ocean is in equilibrium with the atmosphere and its buffering capabilities are far from exhausted- the pH of the ocean is 7.8-8.4, which is still basic, not acidic.


5. The planet has had CO2 levels 20x higher in the past and did fine.
The greenhouse gas qualities of carbon dioxide have been known for over a century. In 1861,John Tyndal published laboratory results identifying carbon dioxide as a greenhouse gas that absorbed heat rays (longwave radiation).

https://www.jstor.org/stable/108724?...o_tab_contents

Since then, the absorptive qualities of carbon dioxide have been more precisely quantified by decades of laboratory measurements (Herzberg 1953, Burch 1962, Burch 1970, etc).

The problem with the analogy is that we won't be able to avoid the warming. The climate always has changed and will even if people stop producing CO2. We have to find a way to live with it.

Conjecture and theory proves nothing.

Human caused warming is different than natural warming because of the time scales involved. Inter-glacial periods in the ice ages had warming periods that occurred over thousands of years. We are warming at a rate about 10x faster. Evolution cannot work fast enough to let species evolve on those time scales. And for humans it will likely be very disruptive also. People get desperate when their food and water disappears which will lead to massive migration and conflict. If all we had to worry about were the natural climate trends it would be far easier. Read Jerrod Diamond's work on the collapse of civilizations due to ecological problems caused by the people. It has happened several times, just on a smaller scale.

That figure is for Fort Yukon, an interior location at 66° north, right at the Arctic circle where the sun never sets in summer. Anchorage is a coastal city at 61° north that does see darkness even on the longest days of the year. 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

Arctic sea ice extent as of August 4th:



Smoke from wildfires that are currently ongoing:



This is NOT normal. How is this so difficult to understand?
