Measuring Climate Change: Why Units Matter

Climate change is a global challenge, and understanding its impact requires precise measurement and clear communication. Scientists, policymakers, and the public rely on standardized units and accurate conversions to track everything from carbon emissions to temperature rise. Without a common language of measurement, it would be impossible to compare data, set targets, or monitor progress worldwide.

According to the IPCC Sixth Assessment Report (2023), global surface temperature has increased by approximately 1.1°C since the pre-industrial era, and carbon dioxide concentrations reached 419 ppm in 2023 (NOAA Global Monitoring Laboratory).

Key Units in Climate Science

  • Temperature: Celsius (°C), Fahrenheit (°F), Kelvin (K)
  • Carbon emissions: Metric tons of CO₂ equivalent (tCO₂e)
  • Energy: Joules (J), kilowatt-hours (kWh), British thermal units (BTU)
  • Sea level rise: Millimeters (mm), inches (in)
  • Precipitation: Millimeters (mm), inches (in)

Unit Conversions in Action

When scientists report global temperature rise, they often convert between Celsius and Fahrenheit for different audiences. Carbon emissions are tracked in metric tons, but may be converted to pounds or kilograms for local reporting. Energy use is compared across countries using joules, kilowatt-hours, or BTUs, requiring careful conversion to ensure fair comparisons. The Our World in Data project provides up-to-date emissions data by sector and country.

Example: Converting Carbon Emissions

1 metric ton CO₂ = 2,204.62 pounds CO₂

The Role of Units in Policy and Communication

International agreements like the Paris Agreement depend on standardized units to set emission reduction targets. Clear unit conversions help policymakers and the public understand the scale of the challenge and track progress over time.
