The average global temperature has increased by a little more than 1° Celsius (2° Fahrenheit) since 1880. Published Jan 29, 2020 Atmosphere Heat Land Water Human Presence World of Change Two-thirds of the warming has occurred since 1975. Latest Global Average Tropospheric Temperatures. Additional figures based on the GISTEMP analysis which require manual effort to create are available from Columbia University web pages maintained by Dr. Makiko Sato; see page 1 and page 2. (2020-02-21) A Focus on Food Can Help Solve Climate Change. Climate experts from NASA and the National Oceanic and Atmospheric Administration (NOAA) will provide the annual release of global temperatures data and discuss the most important climate trends of 2018 during a media teleconference at 11:30 a.m. EST Wednesday, Feb. 6. World of Change: Global Temperatures. Researchers say this shifting pattern of ocean heat accounts for the slowdown in the global surface temperature trend observed during the past decade. Writing in Real Clear Markets, Aaron Brown looked at the official NASA global temperature data and noticed something surprising. History of global temperature since the mid-nineteenth century through 2018 compared to the 1981-2010 average from four analysis teams: NOAA (red), NASA (tan), University of East Anglia (pink), and the Japan Meteorological Agency (orange). This page is updated each month by an automatic procedure. GISS Surface Temperature Analysis (v4) Analysis Graphs and Plots. NASA scientists have observed Earth’s surface is warming, and many of the warmest years on record have happened in the past 20 years. Since 1979, NOAA satellites have been carrying instruments which measure the natural microwave thermal emissions from oxygen in the atmosphere. Climate change describes a change in the average conditions — such as temperature and rainfall — in a region over a long period of time. The global temperature record shows the fluctuations of the temperature of the atmosphere and the oceans through various spans of time.

As of June 2019, the current GISTEMP version is v4 and may be accessed at data.giss.nasa.gov/gistemp .

There are numerous estimates of temperatures since the end of the Pleistocene glaciation, particularly during the current Holocene epoch.

Powered by the Discover supercomputer, climate simulations incorporated a dynamic ocean to explore the habitability of Proxima Centauri b. This page is updated each month by an automatic procedure. Two-thirds of the warming has occurred since 1975. Wet areas may become wetter, dry areas drier, storms more intense, leading to more chaotic weather around the world. 2018 Fourth Warmest Year in Continuing Warming Trend, According to NASA, NOAA Earth's global surface temperatures in 2018 were the fourth warmest since 1880, according to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA).
