Need a T-Shirt that has a light blue print at 300dpi. 5×7 print = 1500 x 2100. Amongst the >3M blue pixels scatter around 1200 green pixels. Challenge people to find them.

John Parsons says:
“The Last Glacial Maximum (LGM) was between 26,500 and 19,000–20,000 years ago, and CO2 was not only not 4000 ppm, it was far below today’s value. The last time carbon dioxide levels were as high as they are today — and were sustained at those levels — global temperatures were 5 to 10 degrees Fahrenheit higher than they are today, the sea level was approximately 75 to 120 feet higher than today, there was no permanent sea ice cap in the Arctic and very little ice on Antarctica and Greenland… &etc.”

So? Are you saying that correlation is causation? Sounds like it. But in reality, all you are showing is a coincidence.
Look here. CO2 has been up to twenty times higher in the past — when the biosphere teemed with life and diversity.
Your attempted scare stories are not helpful. They amount to nothing but baseless climate alarmism. There really is no problem with the current 0.04% CO2. The biosphere could use a lot more CO2, and it would still be no problem.
