National Geographic? Nice pictures but I would rate them pretty much near the bottom as an authority on climate.
NASA and NOAA are political entities and as such are tainted. If Obama tells them to fudge the data they do it.
Do you honestly think that any government employee at either of those institutions is going to step over the line when the Dictator/Emperor does stuff like this:
Call out climate change deniers
There is a full blown democrat led McCarthy style witch-hunt going on right now for scientists who fail to accept the dogma.
Read these:
The last climate science witch hunt

Their guess is not an answer.

Again that doesn't answer the question - what is the ideal temperature for the planet? Like I said before we are near all time historic lows for temperature. Life has flourished in greater quantity in warmer temperatures than we have now. The history of the planet did not begin 80 years ago.
Keep in mind - frost and ice = death, warmth = life - except of course for the very few species adapted to life in frost and ice. Just compare the abundance of life in the equatorial rainforests to the scarcity of life at the frozen poles.

Another non-answer. During the Eemian sea levels were up to 20 feet higher than today. Where in the variance of +/-20 feet is the ideal sea level? If Eemian sea level rise was natural, why can't current sea level rise be natural? Again, the history of the planet did not begin 80 years ago.

Congrats for trying but none of the questions were actually answered.
