We humans are at the centre of Climate change and things are only getting worse. A new study shows that humans activities have been changing our planet’s rainfall and drought pattern since the Early 20th Century.
According to the study, drier regions of our planet are getting even drier and the wetter are getting even more wetter. These results are based on the long-term paper tracks in the soil moisture across various regions Earth, including Eurasia, Central America, North America and the Mediterranean. Furthermore, the researchers also combined their findings with the computer models, eventually revealing a bigger picture on global drought that dates back centuries and includes human fingerprint.
This is not all new because we have always known the effects of producing greenhouse gases in access. Even the study’s author Kate Marvel, a climate scientist at Nasa Goddard Institute for Space Studies and Columbia University, said “Climate Change is not a new thing”. Benjamin Cook, co-author of the study, said “The results of this study provide further understanding on the fundamental processes and impact of climate change on drought.”
The results from the study basically fall under three phases, ranging from the early 20th Century to the 21 Century. The first phase, meaning the period in the early 20th century, showed a significant human fingerprint leading to climate change. Then from the 1950 to the 1975, meaning the midcentury, the fingerprint tends to decrease, maybe due the heavy release of aerosol pollutants that eventually blocked some sunlight from reaching Earth. The third phase, the period after 1980, again sees a rise in human fingerprint, potentially due to the restriction applied on aerosol pollutants.
The author of the study said that more extensive research is needed and also noted that one of the solutions for fighting the currently rising temperatures also involves spraying aerosol into the atmosphere, which will partially block sunlight from reaching the ground. This method has also been suggested earlier in various studies.
Other researchers from various parts of the world appreciated the results, in-which Abigail Swann, a climate scientist, said “It shows a pretty creative way to leverage drought information of the earlier part of the century”.
Other than that we need to understand that climate change in something fictional, but rather is an actual phenomenon that is actually occurring or should I say that it has been occurring since the early 20th Century. Don’t take it for granted.
