Earth’s Temperature Could Increase by 25 Degrees: Startling New Research Reveals That CO2 Has More Impact Than Previously Thought

Analysis of Pacific Ocean sediments shows doubling atmospheric CO2 might raise Earth’s temperature by up to 14 degrees, exceeding IPCC predictions, with historical data indicating significant future climate impacts.

Doubling the atmospheric CO2 levels could raise Earth’s average temperature by 7 to 14 degrees Celsius (13 to 25.2 degrees Fahrenheit), according to sediment analysis from the Pacific Ocean near California conducted by researchers from NIOZ and the Universities of Utrecht and Bristol.

The results were recently published in the journal Nature Communications.

“The temperature rise we found is much larger than the 2.3 to 4.5 degrees Celsius (4.1 to 8.1 degrees Fahrenheit) that the UN climate panel, IPCC, has been estimating so far,” said the first author, Caitlyn Witkowski.

The researchers used a 45-year-old drill core extracted from the bottom of the Pacific Ocean. “I realized that this core is very attractive for researchers, because the ocean floor at that spot has had oxygen-free conditions for many millions of years,” said Professor Jaap Sinninghe Damsté, senior scientist at NIOZ and professor of organic geochemistry at Utrecht University.

“As a result, organic matter is not broken down as quickly by microbes and more carbon is preserved,” Damsté said. He was also the supervisor of Witkowski, whose doctorate thesis included this research.

1. Virtually uninhabitable

3. I think it has to do with the moon moving away from earth.

We’re eventually going to be sucked up by the sun. The 25 degrees is probably while we travel to the sun by the pull.

7. Earth won't travel to Sol. Sol will travel to Earth in 4B years.

9. Thank you. I got it opposite.

2. The Earth has experienced at least five major

mass extinctions in it's 4.5 billion year lifetime. I would presume there will be more before the Sun turns into a red giant and incinerates the whole planet.

4. This one looks like a slow but steady fricassee. Won't be a sudden meteor impact.

Not sure, but perhaps a nuclear armaggedon might be preferable.

5. The Permian Extinction wasn't sudden either.

Don't need a meteor impact to cause one. The Permian Extinction killed off more than 96 percent of the planet’s marine species and 70 percent of its terrestrial life. It was not instantaneous or sudden. Depending on which group of scientists one reads, the extinction even lasted for as long as 15 million years, with a competing theory suggesting the event only took 200,000 years with most of the die off occurring during the last 20,000 years.

This extinction was likely due to climate change related to volcanic activity which produced massive quantities of carbon dioxide.

The US produces lots of oil and gas from the Permian Basin. Ever wonder why all that petroleum is a fossil fuel?

6. The Permian Extinction heating runaway was about 12 to 15 years

We are just going into exponential temperature increase now. All that Arctic Methane Hydrate is already close to the tipping point for runaway warming. I believe our only chance is a Mega Volcano giving us a brief pause. Even 3 degrees Celsius will make life hard for Humans, 5 degrees Celsius might just kill most of our plants. The most scary thing about this is it is happening too fast for anything to evolve or move. Here are the details from a climate expert from Rutgers. https://arctic-news.blogspot.com/
