Few studies in the past did bring out the positive effects of climate change or global warming but got dismissed in view of the dangers associated with it. Now a new study says the Sahel area in Africa has witnessed 4 more inches of rainfall than in the past owing to greenhouse emissions and global warming.
The study published in the journal Nature Climate Change said the Sahel region, bordering the Sahara Desert was written off with chronic drought killing thousands of people that even prompted the Bob’s Live Aid concert in 1985, is getting more rain now due to global warming, pointing out the positive effects of CO2 emissions.
The Sahel region covers parts of (from west to east) Senegal, southern Mauritania, central Mali, northern Burkina Faso, extreme south of Algeria, Niger, extreme north of Nigeria, central Chad, central and southern Sudan, and northern Eritrea.
In fact, there is on record similar postive effect of global warming on coconut plants and high yield in a study conducted by Indian agricultural scientists from ICAR in Kerala. ICAR Scientists successfully concluded in their study during the early 2000s that global warming did help high coconut yield in the CPCRI institute based in Kasargod.
The problem is that the benefits of green house effects were undermined in view of the euphoric stance around the world over gloabl warming, say the scientists. “Scientists have known for 15 years that the Sahel was greening up and desertification was reversing there,” Pat Michaels, a Climatologist, pointing out that the Sahel area attributed to more CO2 in the atmosphere.
While the scientists are careful not to brush aside the effects of global warming which may erode several island nations off the world map even if the water bodies rise by 2%, said the time is ripe to prepare for climate change in focusing on garnering the best possible benefits.
As of now, global temperature has risen about 1.7 degrees compared to the 20th century figures but the UN studies have warned that the global warming between 2.5 to 5.5 degrees over the next century is possible affecting the food production and impacting the world GDP by 1.1% lower by the turn of this century.
The study, however, seeks a follow-up research to reiterate the importance of global warming and work on relevant climate models. “It will be important to repeat our study with other climate models, including at higher resolution,” said co-author Buwen Dong.
Since the harm outweighs benefits, a strategic focus on reaping the best while addressing the climate change are required.
