Carbon Dioxide Emissions Set to Hit Record Highs in 2025

Context:

The forecast for atmospheric carbon dioxide (CO2) levels in 2025 reveals alarming projections that underscore the urgent need for global climate action to avoid exceeding the 1.5°C temperature rise target set by the Paris Agreement.

Projected CO2 Concentrations

In May 2025, CO2 levels are forecast to reach 429.6 ppm, the highest recorded in over 2 million years.
This represents an increase of 2.26 ppm from 2024, which is unsustainable for meeting the 1.5°C global warming target.

Rising CO2 Levels and Unprecedented Increases

2024 saw the fastest-ever annual increase in CO2 concentrations, rising by 3.58 ppm (surpassing the predicted increase of 2.84 ppm).
A significant contributor to this rise is record-high fossil fuel emissions, reduced carbon capture by forests, and the impact of wildfires.

Wildfires and Emissions

Global wildfires in 2023 emitted approximately 7.3 billion tonnes of CO2, exacerbating atmospheric CO2 levels.
Fossil fuel emissions in 2024 reached an all-time high of 41.6 billion tonnes, marking a notable increase from 40.6 billion tonnes in 2023.

Impact on Climate and Global Warming

Rising CO2 levels act as a heat trap, causing higher global temperatures and contributing to severe weather events like heatwaves, storms, and floods.
2024 was the warmest year on record, with extreme weather events leading to widespread destruction and loss of life.

Regional Impact: India

In India, extreme weather events in 2024 claimed the lives of at least 3,200 people according to the India Meteorological Department (IMD).

Future Projections and Climate Risks

Global temperatures are expected to continue rising, with 2025 likely to be one of the three hottest years on record.
The World Meteorological Organisation (WMO) predicts intensifying extreme weather events that will rank as the second most severe global risk from 2025 to 2027.

Urgent Action Needed

Need for Urgent Action: To prevent further global warming, it is essential to stop the buildup of greenhouse gases and rapidly reduce emissions.
International Cooperation: Significant international efforts and rapid emission cuts are critical to limiting global temperature increases and mitigating the severe consequences of climate change.
