Warning global surface temperatures have increased by more than 25% since 1900

With a record increase in the period 2014-2016, global growth has increased by more than 25% since 1900 until now.

The study was conducted by the University of Arizona in the United States and published in Geophysical Research Letters.

The researchers analyzed 15 different data sets, including monitoring the global average surface temperature from 1850-2016, ocean temperature from 1955-2016, recorded from 1948 -2016 and documentation on cycles .

They found that the average temperature of the Earth's surface has increased by about 0.9 degrees Celsius since 1900-2013.

When analyzing global temperature records, scientists found that by the end of 2016, global surface temperatures had increased by 0.24 degrees Celsius. This is an unprecedented increase in 20th and 21st centuries.

According to University of Arizona researcher Jianjun Yin, the analysis shows that the underlying cause of a record-breaking global temperature is due to the effects of.

The researchers also forecast the frequency of global temperature rise of 0.24 degrees Celsius in this 21st century depending on the amount of greenhouse gases emitted from now until 2100.

In two cases, if greenhouse gas emissions peak at 2020 and then decline, global temperature rise of at least 0.24 degrees Celsius may not occur or occur once or twice in the world. this 21st century.

In the opposite case, if the amount of greenhouse gas emissions increased in the entire 21st century, the record-breaking temperature phenomenon may appear from 3 to 9 times between now and 2100.

If you can reduce greenhouse gas emissions, people can reduce the number of occurrences of record breaking temperatures in the 21st century and can also reduce risks, according to Professor Jianjun Yin.
