Yes, the IPCC conducts no research. They do, however, conduct very thorough reviews of the Assessment Report sections before they are published. I stand by my answer, though, as you point out, there are mountains of other published studies of climate issues with very close to unanimously support for the conclusions of the IPCC, which certainly makse sense since that is where the IPCC's conclusions come from.
Ooh, second year Calculus. VERY impressive. Was that before junior college or during?
So as a geologist you should be aware of the role plate tectonics played in affecting earth’s climate.
I don’t. I am talking about the role plate tectonics played in the earth transitioning from a greenhouse planet to an icehouse planet. As a geologist can you tell me about that?
Correct, you will find some days will break "records" as the records are only 150 years-ish old. Obviously there have been colder and hotter days in the earth's history who's data spans billions of years.The occurrence of new records, new extremes, at BOTH poles has significance, particularly when overlain on the steady rise of global temperatures over the last century.
Hot poles: Antarctica, Arctic 70 and 50 degrees above normal
Parts of Antarctica Friday hit 70 degrees warmer than normal. At the same time parts of the Arctic were 50 degrees warmer than normal. Scientists are stunned.apnews.com
Not snowball earth. ~ 3 million years ago the earth transitioned from a greenhouse planet to an icehouse planet (I.e. bipolar glaciation). Prior to that transition the planet had been slowly cooling for ~50 million years with CO2 lagging temperatures by 800 to 1000 years due to CO2 sequestration by the ocean which is a function of CO2 solubility of water versus temperature.
Let's stay focused on the conditions which exist today which are polar regions being isolated from warmer marine currents and temperatures at or below the thresholds for extensive continental glaciation. Fair enough?
Actually bipolar glaciation is quite rare. There's no geologic record of it occurring except in the past 3 to 5 million years.
Yes and my point is that it is northern hemisphere glaciation which is responsible for the planet's increased climate fluctuations and environmental uncertainty over the past 5 million years or so. So we shouldn't be so quick to dismiss natural causes for the recent warming trend as climate fluctuations and environmental uncertainty are hallmarks of a bipolar glaciated world whose temperature is close to the threshold for extensive continental glaciation.
Here's the thing you have to remember... Milankovich Cycles have always existed even when the poles had no ice on them at all. So Milankovich Cycles are only part of the equation. The conditions - specifically the thresholds for extensive continental glaciation in the polar regions - have to be present for the Milankovich Cycles to trigger glacial events.
