Annual data comprises the arithmetic average of twelve month's data from the NOAA/NCEI source. 2023 data in Version 1 is through October 2023. Source of data for series of charts titled "mm Month - Percent of global area at temperature records - Global warming - NOAA.svg": — Source's title/subtitle: "Mean Monthly Temperature Records Across ...

There is good agreement on the overall evolution of global temperatures and year-to-year variability. Dataset anomalies are calculated relative to a 1981 to 2010 baseline and offset by 0.69°C, which is the best estimate difference for that period from the 1850-1900 average given in the IPCC sixth assessment report."
Top chart: Earth's climate has cycled between ice ages and warm interglacial periods, with each cycle taking tens of thousands of years or more. Middle chart: Global average temperature was in a cooling trend for thousands of years before fossil fuel based industrialization. Since then, it has increased about a full 1°C—in a time period less ...
The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890. The temperature on land rose by 1.59 °C while over the ocean it rose by 0.88 °C. [3] In 2020 the temperature was 1.2 °C above the pre-industrial era. [4]
Data released by the Copernicus Climate Change Service last week showed that March of 2023 was the planet’s second-warmest month in recorded history, registering average global temperatures 0.92 ...
This is a list of countries and sovereign states by temperature. Average yearly temperature is calculated by averaging the minimum and maximum daily temperatures in the country, averaged for the years 1991 – 2020, from World Bank Group , derived from raw gridded climatologies from the Climatic Research Unit .
This 12-month average does not mean that the world has yet surpassed the 1.5 C (2.7 F) global warming threshold, which describes a temperature average over decades, beyond which scientists warn of ...
