Table. 16. Our futuristic results from Carbon Dioxide (CO2) varying temperature added to IPCC scenarios assessment in 21st century.

Table. 16. Based on the assessment of multiple lines of evidence, global warming of 2°C, relative to 1850–1900, would be exceeded during the 21st century under the high and very high GHG emissions scenarios considered in that report (SSP3-7.0 and SSP5-8.5, respectively), the table also shows the three main Scenarios of assessments based on multiple lines of evidence in the first seven rows (IPCC, 2021); the last two rows illustrated the extreme possible temperatures due to accumulation of CO2 with current rate, running without control, as derived from Table 14 and graph in Fig. 17.
