Unprecedented Atmospheric Conditions: CO2's Impact on Climate Revealed
A new study published in the journal Science reveals that the last time carbon dioxide (CO2) levels in the atmosphere consistently matched today's human-driven levels was 14 million years ago. The research, which covers a period of 66 million years, indicates that the current CO2 concentration of 420 parts per million (ppm) is far higher than previously estimated. The study warns that if global CO2 emissions continue to rise, levels could reach between 600-800 ppm by 2100, leading to significant climate changes. The findings highlight the unprecedented nature of human-induced climate change and the urgent need to reduce CO2 emissions to mitigate its long-term effects.
