Could have told you that - Earth's Carbon Cycle

Of which Carbon Dioxide (ie: plant food) is the rallying cry for a bunch of delusional . innumerate . useful idiots.

Scientists say solar system affects Earth's carbon cycle
Scientists have discovered evidence that Earth's carbon cycle and global climate is influenced by periodic changes in the shape of Earth's path around the sun.

According to a new study, published this week in the journal PNAS, scientists found the evidence hiding in ancient layers of mudstone.

Chemical analysis of the ancient mudstone revealed links between past orbital changes and two major extinction events, the Triassic-Jurassic mass extinction event, around 201 million years ago, and the Toarcian extinction event, or Toarcian turnover, around 183 million years ago.

"Our work shows that for the 18 million years or so in between the Triassic-Jurassic mass extinction and the Toarcian oceanic anoxic event, Earth's global carbon cycle was in a constant state of change," Micha Ruhl, assistant professor in sedimentology at Trinity College Dublin in Ireland, said in a news release. "Periodic changes in the shape of Earth's orbit around the sun impacted on the amount of energy received by Earth from the sun, which in turn impacted climatic and environmental processes, as well as the carbon cycle, on local, regional and global scales."

The researchers here were looking at very long timelines. Our Modern Warm Period (1950's through 2006 or so) saw the ice caps on Mars retreat (here, here and here for starters) just as the ice on Earth has retreated. Now, Glacier National Park has begun quietly removing and altering signs and government literature which told visitors that the Park’s glaciers were all expected to disappear by either 2020 or 2030.

Anthropogenic Global Warming is a political movement and not a scientific one. The writings of a few scientists are being used to advance a one-world-government. A socialist tyranny.
