• Global average temperature was 0.98°C (1.76 °F) higher in 2020 than in the late 1800s.15 • The warmest year on record since records began in 1880 was 2016, with 2020 ranking second. In 2020 global average land temperatures experienced a record high, while 2016 global ocean temperatures remain the highest on record.
Based on extensive empirical evidence, it explains weather events that indicate climate change’s evolution and presents important topics connected to climate change, such as political controversies, climate policy, as well as Native American perspectives.
Scientists know that recent climate change is largely caused by human activities from an understanding of basic physics, comparing observations with models, and fingerprinting the detailed patterns of climate change caused by different human and natural influences.
Climate change science seeks to understand the physical, chemical, biological and geological processes, and the interactions among these processes, that produce climate. The scales of interest range from local to global and from weeks or months to millions of years. Changes in climate, both temporally and spatially,
global surface temperature since AR5 is principally due to further warming since 2003–2012 (+0.19 [0.16 to 0.22] °C). Additionally, methodological advances and new datasets contributed approximately 0.1°C to the updated estimate of warming in AR6.10 {2.3, Cross-Chapter Box 2.3} (Figure SPM.1)
ocean circulation and SST forcing can be in influencing the global temperature. At the same time, it is clear that greenhouse gas forcings have been important but that shifts in vegeta-tion, and feedbacks in albedo and the carbon cycle from those vegetational shifts can also be important.
