The first part of the IPCC's 5th Assessment Report illustrate the physical science basis of climate change

The Intergovernmental Panel on Climate Change (IPCC) published the report of the Working Group I contribution to the Fifth Assessment Report in September 2013. It focuses on the physical science basis of climate change. The Finnish Meteorological Institute and the Ministry of the Environment have produced infographics on the key messages of the report. The infographics, or information graphics, can be freely used by the public and the media.  [1]

Note: When using the infographics, please cite the Finnish Meteorological Institute, the Finnish Ministry of the Environment, and Climateguide.fi as references.

The complete set of the infographics can be downloaded as a PDF file, and the individual images are also available in JPG and PNG formats. The images have been divided according to their themes under the headings in thetable of contents.

Observed changes

Observed changes in the atmosphere

Figure 2: Increase in the concentrations of greenhouse gases.

Figure 3: Concentrations of carbon dioxide, methane, and nitrous oxide in the atmosphere. Concentrations are expressed in parts per million (ppm) for carbon dioxide and parts per billion (ppb) for the other two gases. IPCC correction (11.11.2013): The value given for cumulative carbon dioxide emissions from fossil fuel combustion and cement production since 1750 should read 375 PgC (instead of 365).

Future temperature changes

Figure 17. Projected changes in temperature. The left side portrays the change if greenhouse gas emissions are reduced substantially as in pathway 1 (RCP 2.6). The right side portrays the change if the emissions continue to grow at the current rate as in pathway 2 (RCP 8.5). These estimates include a calculated best estimate (in the middle) and a confidence interval (the highest and lowest numeric values).

Future sea level

Figure 18. Projected changes in sea level. The left side portrays the change if greenhouse gas emissions are reduced substantially as in pathway 1 (RCP 2.6). The right side portrays the change if the emissions continue to grow at the current rate as in pathway 2 (RCP 8.5). These estimates include a calculated best estimate (in the middle) and a confidence interval (the highest and lowest numeric values).

Future precipitation

Figure 19. Projected changes in precipitation. The left side portrays the change if greenhouse gas emissions are reduced substantially as in pathway 1 (RCP 2.6). The right side portrays the change if the emissions continue to grow at the current rate as in pathway 2 (RCP 8.5). For Finland, the estimates include a calculated best estimate (in the middle) and a confidence interval (the highest and lowest numeric values).
