Detailed explanation-1: -2020 is very likely to be one of the three warmest years on record globally. Modern temperature records began in 1850. The WMO assessment is based on five global temperature datasets. All five of those datasets currently place 2020 as the 2nd warmest for the year to date, following 2016 and ahead of 2019.

Detailed explanation-2: -The data in this report show that the global mean temperature for 2020 was around 1.2 °C warmer than pre-industrial times, meaning that time is fast running out to meet the goals of the Paris Agreement. We need to do more, and faster, now. This year is pivotal.

Detailed explanation-3: -This compares with 1.09°C from 2011 to 2020, as estimated by the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment report. Ocean heat was at record levels in 2021 (the latest year assessed), with the warming rate particularly high in the past 20 years.

Detailed explanation-4: -The global mean temperature for 2020 (January to October) was 1.2 ± 0.1 °C above the 1850–1900 baseline, used as an approximation of pre-industrial levels (Figure 1). 2020 is likely to be one of the three warmest years on record globally. The WMO assessment is based on five global temperature datasets (Figure 1).

Detailed explanation-5: -Continuing the planet’s long-term warming trend, global temperatures in 2022 were 1.6 degrees Fahrenheit (0.89 degrees Celsius) above the average for NASA’s baseline period (1951-1980), scientists from NASA’s Goddard Institute for Space Studies (GISS) in New York reported.
