Greenhouse Gas Emissions Break Records, Temperature Rise to Last for Decades

Greenhouse Gas Emissions Break Records, Temperature Rise to Last for Decades
In 2023, the level of greenhouse gases has reached record highs, the highest seen in the past two decades. Over the last 20 years, there has been an increase of more than 10% in emission levels.
According to the annual Greenhouse Gas Bulletin of the World Meteorological Organization (WMO), the Earth's carbon dioxide (CO2) levels have reached 151% of pre-industrial levels (1750). Additionally, levels of other greenhouse gases, such as methane and nitrous oxide, have also surged. This increase in greenhouse gases is leading to a rise in global temperatures, threatening the world’s ecosystems and communities.
For the year 2023, the average CO2 concentration has surpassed 420 parts per million (ppm).
Threat to the World's Ecological Systems and Communities
In the past 20 years, CO2 levels have increased by 11.4% (42.9 ppm) compared to the 1990 levels. This increase in greenhouse gases, particularly CO2, poses severe risks to ecosystems worldwide and puts various communities in danger.
The methane levels have reached 336.9 ppm, marking a 165% increase from pre-industrial levels, indicating a significant rise since the beginning of the industrial age.
