1) The settled science on climate change
''We are in an interglacial cycle. Our present temperature is well below the peak temperatures of previous interglacial cycles. We are within the norm, dumbass.

Science confuses them.
Then he is going to hate this, lol.
Wow... doesn't that look like we have a problem!!!!
Not really. It is all part of a natural cycle that has been occurring for the past 400,000 years.
The world we live in today is an icehouse world. It is characterized by bipolar glaciation.
We think of this as normal, but it's not. For most of the past 55 million years our planet was a greenhouse world.
Bipolar glaciation is geologically rare, possibly unique. No other previous instance of bipolar glaciation has been recorded in the geologic record.
The icehouse world we live in today is characterized by glacial - interglacial cycles and a high latitudinal thermal gradient.
The oxygen isotope curve is well established for the Cenozoic and shows that the trend is for a COOLING earth. Over the last 5 million years there has been rapid cooling.
Climate models predict that extensive glaciation cannot occur at the South Pole until atmospheric CO2 reaches 600 ppm. Climate models predict that extensive glaciation cannot occur at the North Pole until atmospheric CO2 reaches 250 ppm.
Five million years ago the earth started going through glacial / interglacial cycles. The glacial / interglacial cycles of the past 5 million years were triggered by Milankovitch cycles. But before the glacial cycle could be triggered, two conditions needed to be met; the north and south poles had to be isolated from warm marine currents and atmospheric CO2 needed to be 400 ppm or less. These conditions still exist today.
The north pole is isolated by landmasses. The south pole is isolated because of Antarctica.
