A data-driven overview of our changing climate
Understand key climate data through current values, historical context, and projections.
| Metric | Current Value | Historical / Projection | Explanation |
|---|---|---|---|
| CO₂ Concentration (ppm) | ~415 ppm | Pre-industrial: ~280 ppm | Measures CO₂ in the atmosphere—a primary driver of global warming. |
| Global Temperature Anomaly (°C) | +1.1 °C | Potential rise to +2 °C or more by mid‑century | Reflects the increase above pre-industrial levels. |
| Sea Level Rise | ~8 inches since 1880 | Projected to increase further in coming decades | Indicates the impact of melting ice and thermal expansion. |
| Arctic Sea Ice Extent | ~4.3 million km² (summer minimum) | Declining over the last 40 years | Serves as an indicator of Arctic warming. |
Breakdown of greenhouse gas emissions by key sectors reveals targets for effective climate policy.
| Sector | % of Global Emissions | Description |
|---|---|---|
| Energy Production | ~35% | Emissions from power plants and fuel combustion. |
| Transportation | ~14% | Emissions primarily from motor vehicles, aviation, and shipping. |
| Industry | ~21% | Includes manufacturing, cement production, etc. |
| Agriculture & Land Use | ~24% | Emissions from agriculture, livestock, and deforestation. |
