Interesting!

The dramatic draw-down of carbon dioxide cooled the atmosphere, the new study suggests, and set the planet up for two ice ages, 80 million and 50 million years ago.

I swear the stupidity in science today is astounding !

CO2 went down because of the ice age ! the plants which consume CO2 DIED because of the ice age and thus CO2 went UP. CO2 didn't CAUSE the iceage! it was a result OF the ice age.

I swear! I kindergartner could figure this out!

Or stick with precession.

For hundreds of millions of years, Earth’s climate has remained on a fairly even keel,

No it hasn’t. Ice ages & warm periods have occurred at regular intervals. We can expect another one in the future.

All of human history has occurred in one of the arm intervals between ice ages.

Around 80 million years ago, the planet’s temperature plummeted, along with carbon dioxide levels in the atmosphere. The Earth eventually recovered, only to swing back into the present-day ice age 50 million years ago.

But that happened when the Earth was still Flat, now that it is Round, does it make a difference in their projections???

The dead horse beating of CO2 percentage as a climate change cause (effect is a separate matter) must sound like a xylophone by now. Nothing left but dried and hollow bones.

That's not news. We know from studying how plate tectonics work that about 500 million years ago, because of the location of the continents (mostly in the Southern Hemisphere), Earth was supposedly encase in an ice sheet, in some places several miles high. However, over geologic time as the continents shifted along with volcanic activity, the ice sheet melted and we got our modern oceans.

All explanations must now rely on CO2 or the lack thereof. Sense I know CO2 is causality is BS, I know this research is BS.

There is also this gem, "For hundreds of millions of years, Earth’s climate has remained on a fairly even keel..."

[NormsRevenge]

Considering the amount of tectonic activity of late, veyyyy interesting indeed.

Ice ages happen..

Gondwana and Eurasia.? Two supercontinents that eventually split into today’s set.

One would expect someone from MIT would be able to tell cause from symptom.
