A Recent Study: the Earth Is Experiencing an Exceptional Global Warming

 
 
The Earth is at the doorstep of a new phase of global temperature increase, which could reach some levels unwitnessed during the last 1,000 years.

This result was the outcome of a recent study published by Nature Climate Change Magazine. Although accelerated global warming could affect several countries, the North Pole that is steadily losing more and more of its ice, is expected to be mostly damaged.

The study was conducted by researchers at the US National Energy Laboratory, in which they were able to conclude that by 2020 the rate of global temperature increase could exceed 0.45°C per decade; an average greater than peak rates of change during the previous millennia.

Moreover, if emanation of gases that cause global warming remains stable, warming rates could reach 0.7°C per decade. Steven Smith, Head Researcher of the study said that the world is entering a new phase, in which all habits will change in such way that natural phenomena would stop cooping. He added that we need to better understand what is happening and how to be ready to face it.

In order to study the levels of temperature changes, researchers begun to calculate the acceleration of temperatures between 1850 and 1930; a period during which the concentration of greenhouse gases in the atmosphere was low. The results were later compared with the data of temperature increase over the last two millennia through exploring natural sources such as growth rings of trees, samples of coral reefs, and ice core samples in order to verify the accuracy of researchers’ results.

Using this method, scientists were able to calculate the average of change between 1971 and 2020. They found not only that most regions of the planet are out of normal range of temperature change but also; the average of change in Europe, North America, and North Pole is much higher than the mean rate in the rest of the world.

North Pole region is considered the most warming ever among other regions of the globe, whereas the decrease of the ice cap is increasingly accelerating. According to this study, the average of temperature increase in this part of the world could reach 1.1°F per decade by 2014.
