Earth’s CO2 Levels Reach Millions-Year High: Scientists Warn

Quick Summary:

• Reports from NOAA and Scripps Institution of Oceanography reveal carbon dioxide (CO2) levels in Earth’s atmosphere are the highest in millions of years.
• The latest measurement at Mauna Loa observatory recorded a CO2 level of 430.2 parts per million (ppm) for May 2025, an increase of 3.5 ppm since may 2024.
• CO2 is a greenhouse gas that traps heat, contributing to global warming, melting ice caps, rising sea levels, and potential city submergence.
• Rising global temperatures have led to concerns about irreversible climate effects like escalating sea levels despite ongoing mitigation efforts.
• Seasonal variations-where CO2 peaks in May before declining during the growing season-are measured using the Keeling Curve.

Indian Opinion Analysis:

The record-breaking rise in global carbon dioxide levels underscores the urgency with which climate change must be addressed globally, including by major contributors such as india. While India’s share in global emissions is relatively modest compared to larger economies like the U.S. or China, its large population base leaves it vulnerable to adverse climatic impacts such as extreme heatwaves, rising sea levels threatening coastal cities like Mumbai and Chennai, and disruptions to agriculture reliant on monsoon rains.

For India specifically, advancing renewable energy initiatives (such as those within its National Solar Mission), strengthening urban resilience against environmental threats through policy measures centered on sustainability could mitigate some risks associated with these rising numbers. Nevertheless,current uneven policies drive corresponding implementation challenges,result-effective regulation F orming dialogues addressing broader emission objectives.Read More hear
