Supplementary Figure S3 shows the global average surface temperature changes simulated by 12 CMIP6 models compared to the pre-industrial period. Under the SSP245 scenario, the global mean temperature will increase by about 3.0 °C at the end of the twenty-first century. The increase rate of ...
In 2022, Earth Was About 1.11°C (2°F) Warmer Than the Late 19th Century Average Earth’s average surface temperature in 2022 tied with 2015 as the fifth warmest on record, according to an analysis byNASA. Continuing the planet’s long-term warming trend, global temperatures in 2022 were...
In 1979, a National Academy of Sciences report used the term “global warming” to define increases in the Earth’s average surface temperature, while “climate change” more broadly referred to the numerous effects of this increase, such as sea-level rise and ocean acidification (酸化).During...
Increasing concentrations(集中)of greenhouse gases are likely to make climate change faster. Scientists expect that the average global surface temperature could rise 1.6—6.3 degrees by 2100,and the climate in different areas could change differently. Evaporation(蒸发)will increase as the climate warms...
We create ensembles for 1.5, 2, 2.5, 3, 4 and 5 °C with AOGCMs that have a twenty-first-century global mean surface air temperature increase (19-yr running average) of 1.5 ± 0.25 °C, 2 ± 0.25 °C, 2.5 ± 0.25 °C, 3 ± 0.5 °C, 4...

The figure below from the 2013 Intergovernmental Panel onClimate Change(IPCC) report compares the global surface warming projections made in the 1990, 1995, 2001, and 2007 IPCC reports to the temperature measurements. IPCC AR5 Figure 1.4. Solid lines and squares represent measured average global su...
Global warming, the increases of the earth’s average surface temperature, results from greenhouse gases, for example, carbon dioxide, which traps heat that would otherwise escape from the earth. After the trees are cut down and more greenhouse gases are released, the “blanket” around the eart...
Global surface temperatures last month were 2.25 degrees warmer than the 20th century average of 60.1 degrees,breaking previous records,from August 2016,by more than half a degree,according to NOAA researchers. "That to me is a really huge(1)___ from one record to the next," said Ellen ...
To first test the utility of the MAT–CIA equation in modern times, we derive a global-average CIA by substituting global mean surface air temperature (GSAT, 14 °C)44 into this equation. The resulting CIA (73.5) is consistent with previous global-average estimates (71.6–75.5)15,17,45...
