This subject (Global Warming and Environmental Pollution) can be overwhelming and the science complicated. In addition, predictions about the future of the planet often include endless warnings and signs.
The accumulated heat in the oceans reached a new record in 2021 even during Covid-19 Pandemic. The rise in temperature of the seas is one of the best ways to quantify global warming, which is “unambiguous”.
We understand.
In this article we are giving 100 MCQ Questions and Answers on the Global Warming and Environmental Pollution which strengthen the knowledge of aspirants who are preparing for the examinations like UPSC, SSC, SBI, Railways etc.
