Doubling the amount of CO2 in the atmosphere could lead to an increase in the average temperature on Earth by a range of 7 to a maximum of 14 degrees, which is significantly more than the 2.3-4.5 degrees estimated by the UN climate commission IPCC.

This conclusion was reached by an international group of scientists after analyzing sediments from the Pacific Ocean off the coast of California, reports the press service of the Royal Netherlands Institute for Marine Research.
Scientists used a seafloor soil sample to estimate the CO2 content in the atmosphere over the past 15 million years. It turned out that CO2 concentrations fell from about 650 parts per million 15 million years ago to 280 just before the industrial revolution.
When the researchers plotted the resulting temperature and atmospheric CO2 levels over the past 15 million years, they found a strong relationship: the average temperature 15 million years ago was more than 18 degrees – 4 degrees warmer than today, and about the level the IPCC predicts for 2100 according to the most extreme scenario.
Therefore, this study gives us a glimpse of what the future may hold if we take too few steps to reduce CO2 emissions and implement too few technological innovations to offset emissions, the scientists note.
This study provides a clear warning: CO2 concentration likely has a larger effect on temperature than we currently account for! – the researchers add.
The earth is being deformed due to climate change.
