Earth’s climate history has been quite dramatic
Reportedly over the past 800,000 years, Earth has experienced eight cycles ranging from warmer periods to ice ages. The last ice age ended 11,700 years ago, marking the beginning of the modern climate we see today and enabling the rise of human civilization. While these historical climate changes were caused by minor variations in Earth’s orbit affecting solar energy received, we are currently witnessing another major shift, raising questions about whether orbital changes are involved.Meanwhile Dr. Sanju Purohit, Associate professor (Volunteer) at Akamai university, USA, and a Research Fellow at the women Researcher Council at azerbaijan State university of economics (UNEC), explains, “The current climate change results from human activities that intensified post mid-1800s. Such climate change was unprecedented in previous millennia, prompting scientists to investigate its causes. They found that atmospheric gases produced by human activities trap the Sun’s energy in the atmosphere, warming the land, atmosphere, and oceans, leading to rapid changes globally."Rising temperatures cause glacial melting in the Himalayas, resulting in floods and droughts in various regions. Climate change also disrupts the indian monsoon, while higher temperatures accelerate ground-level ozone formation. Since ozone is a key component of smog, this worsens air quality in indian cities where pollution levels are already high.
