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.
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.
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."
English: Charts comparing percentages of Earth's surface reaching record temperatures since 1951, comparing records for January, April, July and October, from NOAA data. Source of data for series of charts titled " mm Month - Percent of global area at temperature records - Global warming - NOAA.svg":
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 ...
Johns Hopkins Coronavirus Resource Center: Global aggregated data including cases, testing, contact tracing, and vaccine development [12]; World Health Organization (WHO) Coronavirus Disease Dashboard: a database of confirmed cases and deaths reported globally and broken down by region. [13]
Weekly confirmed COVID-19 deaths Map of cumulative COVID-19 death rates by US state. [1] The CDC publishes official numbers of COVID-19 cases in the United States. The CDC estimates that, between February 2020 and September 2021, only 1 in 1.3 COVID-19 deaths were attributed to COVID-19. [2]
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 .
