Here is what the mission will observe at every wavelength. Since the beginning of the Industrial Revolution, the acidity of surface ocean waters has increased by about 30 percent.B.D. Just in the last 650,000 years there have been seven cycles of glacial advance and retreat, with the abrupt end of the last ice age about 11,700 years ago marking the beginning of the modern climate era — and of human civilization. These calculations produce the global average temperature deviations from the baseline period of 1951 to 1980.NOAA scientists used much of the same raw temperature data, but with a different interpolation into the Earth’s poles and other data-poor regions.

The Arctic region has warmed slightly more than three times faster than the rest of the world since 1970.Rising temperatures in the atmosphere and ocean are contributing to the continued mass loss from Greenland and Antarctica and to increases in some extreme events, such as heat waves, wildfires and intense precipitation.NASA’s temperature analyses incorporate surface temperature measurements from more than 20,000 weather stations, ship- and buoy-based observations of sea surface temperatures, and temperature measurements from Antarctic research stations.These in-situ measurements are analyzed using an algorithm that considers the varied spacing of temperature stations around the globe and urban heat island effects that could skew the conclusions.
“Every decade since the 1960s clearly has been warmer than the one before.”The average global surface temperature has risen since the 1880s and is now more than 2 degrees Fahrenheit (a bit more than 1 degree Celsius) above that of the late 19th century. Scientific evidence for warming of the climate system is unequivocal. NOAA’s analysis found 2019's average global temperature was 1.7 degrees Fahrenheit (0.95 degrees Celsius) above the 20th century average.

NASA’s Operation IceBridge images Earth's polar ice in unprecedented detail to better understand processes that connect the polar regions with the global climate system. An interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets worldwide. Data from NASA's Gravity Recovery and Climate Experiment show Greenland lost an average of 286 billion tons of ice per year between 1993 and 2016, while Antarctica lost about 127 billion tons of ice per year during the same time period.

Scheduled to launch in 2023, NASA’s upcoming Plankton, Aerosol, Cloud, ocean Ecosystem, or PACE, mission will measure ocean color to extend data records on ocean ecology and related climate studies. Historical Climate Network (USHCN) where they choose a subset of stations with a long period of record and hopefully good siting and exposure, then "adjust" the observations to remove known biases and inconsistencies. ncreased greenhouse gases from human activities result in climate change and ocean acidification 2014.
Earth's ice cover is shrinking. According to independent analyses by NASA and the National Oceanic and Atmospheric Administration (NOAA), Earth's average global surface temperature in 2019 was the second warmest since modern record-keeping began in 1880.Globally, 2019's average temperature was second only to that of 2016 and continued the planet's long-term warming trend: the past five years have been the warmest of the last 140 years.This past year was 1.8 degrees Fahrenheit (0.98 degrees Celsius) warmer than the 1951 to 1980 mean, according to scientists at NASA’s Goddard Institute for Space Studies (GISS) in New York.“The decade that just ended is clearly the warmest decade on record,” said GISS Director Gavin Schmidt. A space-based laser that measures clouds and small atmospheric particles called aerosols has provided a unique view of the massive Saharan dust plume that crossed the North Atlantic Ocean in June. Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades.An indicator of changes in the Arctic sea ice minimum over time. This body of data, collected over many years, reveals the signals of a changing climate.The heat-trapping nature of carbon dioxide and other gases was demonstrated in the mid-19th century.Ice cores drawn from Greenland, Antarctica, and tropical mountain glaciers show that the Earth’s climate responds to changes in greenhouse gas levels. Version 4.4. Earth’s water is stored in ice and snow, lakes and rivers, the atmosphere and the oceans.
