Earth can get hotter by 25.2 degrees, shocking climate study shows
A shocking climate study shows Earth can get hotter by 25.2 degrees Fahrenheit than current predictions of 8.1 degrees Fahrenheit. This has shown a drastic rise in global temperatures raising high concerns among the scientific community.
A team of scientists conducted this research on sediments from the Pacific Ocean. It shows a significantly higher temperature than the predictions made by IPCC, the Intergovernmental Panel on Climate Change.
If the CO2 amount in the air doubles, it could raise temperatures above the current range of 2.3 to 4.5°C. It is equal to 4.1 to 8.1 degrees Fahrenheit.
NIOZ (Royal Netherlands Institute for Sea Research), the Universities of Utrecht, and Bristol examined sediments in the Pacific Ocean near California. They found that Earth’s temperature can rise by 7 to 14 degrees Celcius or 13 to 25.2 degrees Fahrenheit.
Study lead author Caitlyn Witkowski stated the temperature rise they found is much higher than 2.3 to 4.5°C (4.2 to 8.1°F) than IPCC has been estimating so far.
NIOZ had created the TEX86 method 20 years ago. Scientists used this method to find out what the temperature of seawater was in the past and to estimate how much CO2 was in the air back then.
The study used a 45-year-old drill core extracted from the bottom of the Pacific Ocean. Professor Jaap Sinninghe Damste is a top scientist at NIOZ and a professor of organic geochemistry at Utrecht University. He stated that the ocean floor at that spot has been oxygen-free for many millions of years, which made it a good choice.
Scientists used the chemical composition of chlorophyll and cholesterol to figure out how much CO2 was in the air in the past. They also found that CO2 levels dropped sharply about 15 million years ago. These levels dropped from 650 parts per million to 280 before the 1800s.
They found that the average temperature 15 million years ago was much lower than now by considering the CO2 levels in the air. It was about 18°C (64.4 Fahrenheit) on average which is 4°C (7.2°F) warmer than it is now.
The IPCC predicts temperatures will only get this high in 2100 if the worst possible things happen. Professor Jaap said this study shows us what might happen if we don’t do enough to lower CO2 emissions.
According to Jaap, this study sends a clear message. CO2 levels will greatly impact temperature than they have observed recently. Hence, Earth can get hotter by 25.2 degrees Fahrenheit instead of the current prediction of 8.1 degrees Fahrenheit.
