According to IPCC Sixth Assessment Report, in the last 170 years, humans have caused the global temperature to increase to the highest level in the last 2,000 years. The current multi-century period is the warmest in the past 100,000 years. [3] The temperature in the years 2011-2020 was 1.09 °C higher than in 1859–1890.
The IPCC Fifth Assessment Report (AR5 WG1) of 2013 examined temperature variations during the last two millennia, and cited the following reconstructions in support of its conclusion that for average annual Northern Hemisphere temperatures, "the period 1983–2012 was very likely the warmest 30-year period of the last 800 years (high confidence ...
In recent decades, new high temperature records have substantially outpaced new low temperature records on a growing portion of Earth's surface. [1] Comparison shows seasonal variability for record increases. The list of weather records includes the most extreme occurrences of weather phenomena for various categories. Many weather records are ...

In recent decades, new high temperature records have substantially outpaced new low temperature records on a growing portion of Earth's surface. [50] Comparison shows seasonal variability for record increases. The warmest years in the instrumental temperature record have occurred in the last decade (i.e. 2012-2021).
The IPCC Second Assessment Report (SAR) of 1996 featured Figure 3.20 showing the Bradley & Jones 1993 decadal summer temperature reconstruction for the northern hemisphere, overlaid with a 50-year smoothed curve and with a separate curve plotting instrumental thermometer data from the 1850s onwards. It stated that in this record, warming since ...
This composite of a conventional line chart superimposed on a warming stripe graphic illustrates year-by-year correlation of data points and coloured stripes. [ 21 ] "I wanted to communicate temperature changes in a way that was simple and intuitive, removing all the distractions of standard climate graphics so that the long-term trends and ...
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 .
