updated: Jun 06 2021, 08:46 ist In 2014, a group of 30 scientists from across the world began extracting core samples from the Indian ocean in the hope of finding the response of the Indian monsoon to climate change. Seven years later, they have evidence that India’s monsoon may get more erratic. Scientists across the world already know that climate change is affecting the Indian subcontinent’s annual monsoon cycle. However, there is a shortage of historical data to confirm that human activities are likely to impact the changes. The new study, which was published on Friday in the journal Science Advances, is not only on course to completing six million years of climate data but has confirmed that in the past million years the rise in carbon dioxide in the atmosphere has been followed by substantial increases in rainfall in the monsoon.
