This report covers the range of topics evaluated by Working Group I of the IPCC, namely the Physical Science Basis. This includes:
* an analysis of greenhouse gas emissions and their atmospheric concentrations, as well as the global carbon cycle;
* coverage of the atmosphere, the land-surface, the oceans, and all of the major components of the cryosphere (land-ice, glaciers, ice shelves, sea-ice and permafrost);
* paleoclimate, extreme events, sea level, future projections, abrupt change and tipping points;
* separate boxes devoted to explaining some of the common misconceptions surrounding climate change science.
