According to a recent study, the first signs of global warming date back to the 1940s in the tropics, Africa, Australia, and South-East Asia, World Report Now reports.

Experts were also certain that there was a change in global temperatures between the years 1980 and 2000. However, due to heavier rainfall, during this period, the experts believed that the rise in global temperatures was due to a natural variation.

The study authors said that they studied variations in temperature patterns worldwide to pinpoint the time when exactly global warming occurred. The findings will be utilized to generate new methods of dealing with temperature changes worldwide.

The team discovered that the tropics were the first areas to be affected by global warming. A change in temperature is usually detected easily in the tropics and equatorial regions because these regions have a lower than average range of temperatures.

The researchers said that they first observed unusual changes in the tropics' temperatures in the 1940s, while variations in both Polar Regions were noticed in the early 1980s. Early signs of global warming were also found in Russia, Canada and Northern Europe. A rise in temperatures was also witnessed in Africa, Australia and South East Asia.

That happened a few decades later, along with a warming trend observed in Africa, Australia, and South-East Asia.
