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] In September 2023 the temperature was 1.75 °C above pre-industrial level and during the entire year of 2023 is expected to be 1.4 °C above it. [5]
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 .
English: Green dots show the 30-year average of the new PAGES 2k reconstruction. The red curve shows the global mean temperature, according HadCRUT4 data from 1850 onwards. In blue is the original hockey stick of Mann, Bradley and Hughes (1999 ) with its uncertainty range (light blue). Graph by Klaus Bitterman.

World breaches major threshold. This is the first time any year passed the 1.5-degree threshold, except for a 2023 measurement by Berkeley Earth, which was originally funded by philanthropists who were skeptical of global warming. Scientists were quick to point out that the 1.5 goal is for long-term warming, now defined as a 20-year average.
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 analysis, using billions of measurements from satellites, ships, aircraft and weather stations around the world, also found the last 12-month period, from February 2024 to January 2025, was 1 ...
While last year registered as the warmest calendar year on record at 1.45 C (2.61 F) above pre-industrial temperatures, at least one of the next five years is likely to be even warmer than 2023 ...
