Hasn’t anyone told climate cultists that this year’s IPCC Conference on the Parties has been cancelled, so there’s no reason for the doomy prognostications in the normal runup to it? Or, perhaps it’s the coming election?
Earth barreling toward ‘Hothouse’ state not seen in 50 million years, epic new climate record shows
Sixty-six million years ago, after a massive asteroid hit Earth with the explosive energy of roughly 1 billion nuclear bombs, a shroud of ash, dust and vaporized rock covered the sky and slowly rained down on the planet. As plant and animal species died en masse, tiny undersea amoebas called forams continued to reproduce, building sturdy shells out of calcium and other deep-sea minerals, just as they had for hundreds of millions of years. When each foram inevitably died — pulverized into seabed sediment — they kept a little piece of Earth’s ancient history alive in their fossilized shells.
For decades, scientists have studied those shells, finding clues about the ancient Earth’s ocean temperatures, its carbon budget and the composition of minerals spilling through the air and seas. Now, in a new study published today (Sept. 10) in the journal Science, researchers have analyzed the chemical elements in thousands of foram samples to build the most detailed climate record of Earth ever — and it reveals just how dire our current climate situation is.
The new paper, which comprises decades of deep-ocean drilling missions into a single record, details Earth’s climate swings across the entire Cenozoic era — the 66 million-year period that began with the death of the dinosaurs and extends to the present epoch of human-induced climate change. The results show how Earth transitioned through four distinct climate states — dubbed the Warmhouse, Hothouse, Coolhouse and Icehouse states — in response to changes in the planet’s orbit, greenhouse gas levels and the extent of polar ice sheets.
So, hey, nature causes this kind of stuff to happen, right? But, not, it’s your fault for that fossil fueled vacation you took the other year
“Now that we have succeeded in capturing the natural climate variability, we can see that the projected anthropogenic warming will be much greater than that,” study co-author James Zachos, professor of Earth and planetary sciences at the University of California, Santa Cruz, said in a statement. “The Intergovernmental Panel on Climate Change (IPCC) projections for 2300 in the ‘business-as-usual’ scenario will potentially bring global temperature to a level the planet has not seen in 50 million years.” (The IPCC is a United Nations group that assesses the science, risks and impacts of climate change on the planet.)
For example, about 10 million years after the dinosaur extinction, Earth jumped from a warmhouse state to a hothouse state. This event, known as the Paleocene-Eocene Thermal Maximum, saw temperatures up to 29 degrees Fahrenheit (16 degrees Celsius) above modern levels,…
“We now know more accurately when it was warmer or colder on the planet and have a better understanding of the underlying dynamics and the processes that drive them,” lead study author Thomas Westerhold, Director of the University of Bremen Center for Marine Environmental Sciences in Germany, said in the statement. “The time from 66 [million] to 34 million years ago, when the planet was significantly warmer than it is today, is of particular interest, as it represents a parallel in the past to what future anthropogenic change could lead to.”
Yes, they really do seem to be saying that we will see a 29F increase by 2300, when no one will remember this insance prognostication.
