The blue line represents global surface temperature reconstructed over the last 2,000 years using proxy data from tree rings, corals, and ice cores. [1] The red line shows direct surface temperature measurements since 1880. [2] Global surface temperature (GST) is the average temperature of Earth's surface.
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 timeline is also a year slider, allowing the user to select year for the map. If the user marks an interval of several years on the timeline, the map colors indicate how the value has changed between the first and last year in the interval. A tooltip with country data is shown when the mouse is over a country.
Higher than normal temperatures are shown in red and lower then normal temperatures are shown in blue. The final frame represents the global temperatures 5-year averaged from 2014 through 2018. Scale in degree Celsius." "These calculations produce the global average temperature deviations from the baseline period of 1951 to 1980."
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 .
Copernicus’ preliminary data shows the global average temperature Monday was 17.15 degrees Celsius (62.87 degrees Fahrenheit). The previous record before this week was set just a year ago.
Data for the map and graphs is from the COVID-19 Data Repository by the Center for Systems Science and Engineering (CSSE) at Johns Hopkins University. [ note 2 ] 7-day rolling average . Map of daily new confirmed deaths per million people by country [ 14 ] [ note 2 ] [ note 3 ]
The global average covers 97-98% of Earth's surface, excluding only latitudes above +85 degrees, below -85 degrees and, in the cases of TLT and TMT, some areas with land above 1500 m altitude. The hemispheric averages are over the northern and southern hemispheres 0 to +/-85 degrees. The gridded data provide an almost global temperature map. [3]
