Visitor Essay by Kip Hansen — 10 October 2022
The Monsoon. Life Giving. Life Taking. Bringing each pleasure and sorrow to all of India. As all the time has. It’s believed by some that India’s historical past has been decided by the monsoon and its variability over time. Prayers are mentioned to the goddess Mariamman to convey a positive monsoon.
India’s monsoon is a very powerful meteorological occasion in India yearly — an excellent monsoon means good crops and prosperity for thousands and thousands of farmers and is a such main think about India’s financial well-being that it’s predicted, tracked and reported by India’s central financial institution.
However whereas India’s monsoon will be pretty precisely predicted, it isn’t all the time the identical year-to-year, region-to-region or place-to-place.
Some years it rains an excessive amount of in a single place and too little in one other. Some years are drought years and a few are flood years. Some years are each.
Henry Fountain, a Occasions local weather reporter, and Saumya Khandelwal declare in a current NY Occasions function piece that:
“The Monsoon Is Changing into Extra Excessive — South Asia’s monsoon is inextricably linked, culturally and economically, to a lot of Asia. Local weather change is making it more and more violent and erratic.”
It is a particular “interactive” function, which means that fascinating results have been created by a particular graphics group on the NY Occasions. Test it out on the hyperlink given above. Sadly, like many earlier than it, it’s, at its most simple, “fairly photos used as propaganda”.
Let’s test simply the claims within the sub-title: Local weather change is making the southwest monsoon 1) More and more violent and a pair of) erratic. Henry Fountain doubles down on this declare with this: “Now, nonetheless, throughout South Asia, local weather change is making the monsoon extra erratic, much less reliable and even harmful, with extra violent rainfall in addition to worsening dry spells.”
Let’s see if these claims are true:
More and more Violent, Extra Violent Rainfall:
From this yr’s roundup of the 2022 monsoon season from the India Meteorological Division (IMD), we’ve got this five-year abstract chart:
The chart reveals numbers of “heavy rainfall occasions” throughout the underside – each “simply heavy” (labeled >115.6 and <204.5) and “extraordinarily heavy” (labeled >204.5) for every year. We see that during the last 5 years, extraordinarily heavy rainfall occasions have declined 321, 554, 341, 273, and 296, solely 2019 is unusually larger. The identical is true of simply heavy rainfall occasions. However 2020, 2021, 2022 are fairly regular, with fewer in these years. So, a minimum of the final 5 years haven’t seen “extra violent rainfall”.
Extra erratic, much less reliable:
The monsoon means rainfall in monsoon season, so to be “extra erratic, much less reliable” we should always see rainfall quantities that fall far beneath, or far above, seasonal regular:
It is a 100 and twenty-one yr document, meticulously stored by the governments of India, exactly as a result of the monsoon rains means prosperity or catastrophe for the Indian individuals yr to yr. Years exterior of the green-shaded space — designated by the IMD as Regular +/- 10% — are years of an excessive amount of rain and never sufficient rain. Years exterior the yellow-shaded areas are unhealthy flood years and unhealthy drought years. There are all the time some years within the current many years that fall exterior of regular.
We see that these outside-of-normal years are uncommon within the final 30 years – 1962-1992 noticed way more exterior of the traditional (inexperienced) band than 1992-2022. Fairly than extra erratic and fewer reliable, the newest climatic interval (30 years) has been way more reliable and fewer erratic than the earlier two 30-year intervals.
That mentioned, the monsoon that India will get every year is the monsoon that India will get. Some years are higher than others. Some years are extra evenly unfold geographically, some years are “spottier’ with an excessive amount of rain right here and too little there. That’s what we name climate and is as all the time was.
Backside Line:
It’s not true that “The Monsoon Is Changing into Extra Excessive — Local weather change is making it more and more violent and erratic.”

Writer’s Remark:
I’ve written concerning the monsoon beforehand in 2019 Indian Monsoon – Blessing or Curse? Nothing has modified since then, besides that the primary stream media is increasingly compliant with the demand that journalists exaggerate and bias any and all information that is likely to be associated to climate and local weather – the demand that every one tales declare that there’s a Local weather Disaster evident in each single story.
There can be others who’re extra educated than I writing about this yr’s monsoon – it’s a scorching matter – and a wrap up of the monsoon season story is kind of widespread.
Thanks for studying.
