  • 1880-2009 Global mean surface temperature difference relative to the 1961–1990 average
  • The chart attributes anthropogenic greenhouse gas emissions to eight main economic sectors, of which the largest contributors are power stations (many of which burn coal or other fossil fuels), industrial processes (among which cementproduction is a dominant contributor), transportation fuels (generally fossil fuels), and agricultural by-products (mainly methane from enteric fermentation and nitrous oxide from fertilizer use).
  • Carbon dioxide
  • Methane
  • Water vapor
  • Carbon
  • A representation of the exchanges of energy between the source (the Sun), the Earth's surface, the Earth's atmosphere, and the ultimate sink outer space. The ability of the atmosphere to capture and recycle energy emitted by the Earth surface is the defining characteristic of the greenhouse effect.
  • Greenhouse gas emissions from the agriculture sector account for 22% of the global greenhouse gas emissions, and 80% of this is from livestock production, including transportation and feed. Unlike the burning of fossil fuels, which releases a significant amount of carbon dioxide into the atmosphere, livestock production is mainly associated with methane and nitrous oxide emissions. The primary contributors are enteric fermentation, manure, land-use change, along with soil erosion, artificial fertilizer production and on-farm fossil fuel use.

  • Sea level measurements from 23 long tide gauge records in geologically stable environments show a rise of around 200 millimetres per century, or 2 mm/year.
