The history of the scientific discovery of climate change began in the early 19th century when ice ages and other natural changes in paleoclimate were first suspected and the natural greenhouse effect was first identified. In the late 19th century, scientists first argued that human emissions of greenhouse gases could change Earth's energy ...
Climate change can also be used more broadly to include changes to the climate that have happened throughout Earth's history. [38] Global warming—used as early as 1975 [39] —became the more popular term after NASA climate scientist James Hansen used it in his 1988 testimony in the U.S. Senate. [40] Since the 2000s, climate change has ...
The UAH satellite temperature dataset, developed at the University of Alabama in Huntsville, infers the temperature of various atmospheric layers from satellite measurements of the oxygen radiance in the microwave band, using Microwave Sounding Unit temperature measurements . It was the first global temperature datasets developed from satellite ...
Warming stripes. An early (2018) warming stripes graphic published by their originator, climatologist Ed Hawkins. [ 1] The progression from blue (cooler) to red (warmer) stripes portrays annual increases of global average temperature since 1850 (left side of graphic) until the date of the graphic (right side).

Satellite temperature measurements are inferences of the temperature of the atmosphere at various altitudes as well as sea and land surface temperatures obtained from radiometric measurements by satellites. These measurements can be used to locate weather fronts, monitor the El Niño-Southern Oscillation, determine the strength of tropical ...
The global average and combined land and ocean surface temperature show a warming of 1.09 °C (range: 0.95 to 1.20 °C) from 1850–1900 to 2011–2020, based on multiple independently produced datasets. [5]: 5 The trend is faster since 1970s than in any other 50-year period over at least the last 2000 years.
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.
Deep Space Climate Observatory ( DSCOVR; formerly known as Triana, unofficially known as GoreSat[ 3]) is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. [ 4]
