Arctic sea ice extent both affects and is affected by global climate change. 2014. Scientific evidence for warming of the climate system is unequivocal. ncreased greenhouse gases from human activities result in climate change and ocean acidification
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. Surface Temperature Reconstructions For the Last 2,000 Years. Claim: NASA and NOAA faked climate data in the GISTEMP global temperature record to exaggerate global warming. 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. Video: For 15 years, GRACE tracked freshwater movements around the world “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. The rate of Antarctica ice mass loss has tripled in the last decade.An indicator of the current volume and the Antarctica and Greenland ice sheets using data from NASA’s Grace satellite.

Santer et.al., “Contributions of Anthropogenic and Natural Forcing to Recent Tropopause Height Changes,” Science vol. An interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets world wide. 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. This ancient, or paleoclimate, evidence reveals that current warming is occurring roughly ten times faster than the average rate of ice-age-recovery warming.The planet's average surface temperature has risen about 1.62 degrees Fahrenheit (0.9 degrees Celsius) since the late 19th century, a change driven largely by increased carbon dioxide and other human-made emissions into the atmosphere.An indicator of current global average temperature as measured by NASA; updated annually.An overview of the greenhouse effect and other contributors to abrupt climate change.A visualization of global temperature changes since 1880 based on NASA GISS data.The oceans have absorbed much of this increased heat, with the top 700 meters (about 2,300 feet) of ocean showing warming of more than 0.4 degrees Fahrenheit since 1969.An overview of the ocean’s role in climate change and how it stores and releases heat from the atmosphere.A lighthearted look at the effect of climate change on the world’s oceans and the heat capacity of water.Ocean waters melting the undersides of Antarctic ice shelves are responsible for most of the continent's ice shelf mass loss, a new study by NASA and university researchers has found.The Greenland and Antarctic ice sheets have decreased in mass.
How much do you know about how water is cycled around our planet and the crucial role it plays in our climate? Glaciers are retreating almost everywhere around the world — including in the Alps, Himalayas, Andes, Rockies, Alaska and Africa.An interactive exploration of how global warming is affect sea ice, glaciers and continental ice sheets worldwide. An interactive exploration of how global warming is affecting sea ice, glaciers and continental ice sheets worldwide. This website is produced by the Earth Science Communications Team at Satellite observations reveal that the amount of spring snow cover in the Northern Hemisphere has decreased over the past five decades and that the snow is melting earlier.As an information and referral center in support of polar and cryospheric research,NSIDC archives and distributes digital and analog snow, ice, and Time series of global snow cover from NASA's Earth Observatory.
NOAA’s analysis found 2019's average global temperature was 1.7 degrees Fahrenheit (0.95 degrees Celsius) above the 20th century average. This website is produced by the Earth Science Communications Team at This summer, Siberia has seen potentially record-breaking temperatures as high as 100.4 degrees Fahrenheit (20 degrees Celsius) as well as wildfires burning on a massive scale across the countryside. NASA shares this knowledge with the global community and works with institutions in the United States and around the world that contribute to understanding and protecting our home planet.For more information about NASA’s Earth science activities, visit:The slides for the Jan. 15 news conference are available at: doi:10.7289/V53F4MVPRobinson, D.

Mote. 305 (16 July 2004), 367-371 The U.S. has also witnessed increasing numbers of intense rainfall events.The official website for NASA's fleet of Earth science missions that study rainfall and other types precipitation around the globe. Earth's ice cover is shrinking. The laboratory is affiliated with Columbia University’s Earth Institute and School of Engineering and Applied Science in New York.NASA uses the unique vantage point of space to better understand Earth as an interconnected system.
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.
