Sahara desert is turning green

The Sahara desert is one of the driest places on earth. But surprisingly, US space research agency NASA analyzed satellite images and found evidence of green trees in the Sahara desert.

Cyclones on September 7 and 8 brought heavy rains to large parts of northern and western Africa. Heavy rains have resulted in the accumulation of vegetation in various parts of the Sahara desert. Which is why Morocco, Tunisia, Libya, Algeria are turning green in dry places.

The amount of rainfall in the Sahara has increased significantly. There are occasional floods. Scientists say global warming due to fossil fuel pollution is alarmingly increasing the trend of desertification as well as greening.

Woods Hole Oceanographic Institution president Pietad de Menocal said that when this part of Africa gets a lot of rain, vegetation grows quickly, making the presence of plants easy to see.

According to Kirsten Haustein, a researcher at the University of Leipzig in Germany, there are two reasons for this change in the desert region, the transition from El Niño to La Niño. As a result, the rainfall area has shifted a lot. El Nino effect causes extra heat than normal and La Nino causes the opposite.

Another reason is global warming and the greening of the Sahara desert.

As Kirsten Haustein says, the warmer the world gets, the greener the Sahara will become day by day.

A study published in June in the journal Nature suggests that the Sahara will continue to green up in the coming decades. Greening will not be limited to just the desert. African countries may have to pay a large amount for this. Heavy rainfall is likely in these areas.

Occasional flooding in the Sahara desert, with warming weather increasing the chance of heavy summer rainfall in the Sahara desert region in the coming days. It is causing the danger of flooding. However, it will take a long time for the Sahara desert to become a dense forest.
