Key Points: 1. The global temperature record represents an average over the entire surface of the planet. Air masses in the Earth's atmosphere are highly modified by sea surface temperatures within a short distance of the shore. Global Temperatures. In fact, la Niña was in place across the tropical Pacific from January–April, and it left an imprint on the region's temp… But note that the GISS analysis currently uses the adjusted GHCN v4 data.June 14, 2019:Starting with this release of our monthly analysis, the GISS temperature analysis, G… GISS Surface Temperature Analysis (v4) Analysis Graphs and Plots. According to the American Meteorological Society's State of the Climate in 2018, 2018 came in as the fourth warmest year on record in all four of the major global temperature datasets. GISS Surface Temperature Analysis (v4) Analysis Graphs and Plots. Temperature.Global calculates the current global temperature of the Earth. An example of a temperature anomaly is how much warmer or colder than the long-term average a unit of time something is (like how much warmer than average the most recent year was globally). The 10 highest May global land-only surface temperature departures have … 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. ), • increasing and stronger storms, • Consequently, updates to GISTEMP v3 concluded with the July 2019 update.The Common Sense Climate Index for individual stations is now also based on GISTEMP v4.July 15, 2019:The difference between raw data and the unadjusted data has been clarified on our FAQ site. The exact meaning of surface varies according to the measurement method used, but it is between 1 millimetre (0.04 in) and 20 metres (70 ft) below the sea surface. The Merged Land and Ocean Surface Temperature data are presented as anomalies (departures from a long-term average) on a five-degree by five-degree global grid. Only 2015, 2016, and 2017 were warmer. This indicator tracks average global sea surface temperature from 1880 through 2015. Global warming, the phenomenon of rising average air temperatures near Earth’s surface over the past 100 to 200 years.
The Office of Satellite and Product Operations (OSPO) is part of the National Environmental Satellite Data and Information Service (NESDIS).

This long-term record of global temperature is a key indicator of warming in the climate system.

2. Periods of both have happened regularly throughout earth's history.
Since 1901, the planet’s surface has warmed by an average of 0.7–0.9° Celsius (1.3–1.6° Fahrenheit) per century, but the rate of warming has nearly doubled since … 0.99 °C 1.78 °F The period of record is January 1880 through the most recent month. It uses unadjusted surface temperatures. This page is updated each month by an automatic procedure. It also includes a map to show how change in sea surface temperature has varied across the world’s oceans since 1901. “Since 1906, the global average surface temperature has increased between 1.1°F and 1.6°F” which is 0.6–0.9°C (National Geographic). NESDIS is part of the National Oceanic and Atmospheric Administration (NOAA), and the Department of Commerce. The temperatures we experience locally and in short periods can fluctuate significantly due to predictable cyclical events (night and day, summer and winter) and hard-to-predict wind and precipitation patterns.
