How Global Warming Due To The Industrial Revolution Heated Our Earth In The Last 150 Years

Our Earth, which has been cold for more than 6000 years, has been heated by global warming in only 150 years. If the level of global warming was not so much, then such a situation would not arise for at least 1.25 million years. Scientists at Northern Arizona University in the United States have calculated the temperature from data based on ice cores, sediments deposited at the bottom of lakes, and very old-time organisms, after which this worrying discovery was made.

The temperature increased by 1 degree Celsius

Around 4500 BCE, near the end of the Stone Age, the temperature was decreasing to a rate of 0.1° C per 1000° C, and the time of Little Ice began in 1300 CE. However, in the middle of the 19th century, temperatures began to rise rapidly. The burning of fossil fuels led to the emission of tons of greenhouse gases which were captured in the atmosphere and the temperature rose at a rate of one degree Celsius. It is believed that when the last time the temperature was so high, the sea level was 20 feet higher than today, which is enough to submerge today's cities.

The temperature rises sharply after the industrial revolution

Professor Michael Arb, who studies temperature in research at the University of Arizona, says that earlier, the Earth's cooling was dependent on the rotation of the sun. The Little Ice Age began in the Northern Hemisphere during the summer due to the lack of less sunlight, but the temperature began to rise rapidly after the Industrial Revolution, and scientists afraid that it will continue to rise.



1319 records collected from 679 places to prepare the database

This study mapped the temperature of the last 12 thousand years. The database has been prepared with the help of results based on 1319 data records from 679 locations around the world. Scientists reconstructed mapped temperature with the help of glacial courses, sediments found in the lakes, and marine sediments. They also studied larval fossil deposits of caves, underwater corals, and insects to determine the temperature at that time.

Estimation of climate change in future

The study's co-order associate professor, Niklas Mack, says the last 10 years have been colder than they were in the past and temperatures are likely to be one degree higher than they were before the Industrial Revolution. In the future, rise or fall in temperature will depend on emissions of greenhouse gases by humans, natural phenomena, and changes in climate systems. If natural events and human responsibility are monitored from now, then climate change in the future can also be estimated.
