Earth's average temperature has risen over 1º F in the past century. It is projected to rise an additional 3º to 10º over the next 100 years. Data from NASA's global network of satellites, airborne missions and surface monitoring systems is used to build climate models that help us understand the causes and effects of global warming. :::LEARN MORE::: Key Indicators: Global Surface Temperature climate.nasa.gov/key_indicators/#globalTemp National Climate Assessment: Recent U.S. Temperature Trends nca2014.globalchange.gov/report/our-changing-climate/recent-us-temperature-trends National Climate Assessment: Projected Global Temperature nca2014.globalchange.gov/highlights/overview/overview#graphic-20895 How Will Global Warming Change Earth? earthobservatory.nasa.gov/Features/GlobalWarming/page6.php Long-term Global Warming Trend Sustained in 2013 climate.nasa.gov/news/1029/ The Current and Future Consequences of Global Change climate.nasa.gov/effects/ Earth's Big Heat Bucket earthobservatory.nasa.gov/Features/HeatBucket/ Interactive: Climate Time Machine climate.nasa.gov/interactives/climate_time_machine Quiz: Global Warming climate.nasa.gov/climate_resource_center/16 :::NASA MISSIONS & RESEARCH::: OCO-2 - Orbiting Carbon Observatory-2 oco.jpl.nasa.gov/ AIRS - Atmospheric Infrared Sounder airs.jpl.nasa.gov/ MODIS - Moderate Resolution Imaging Spectroradiometer modis.gsfc.nasa.gov/index.php OSTM/Jason-2 - Ocean Surface Topography Mission sealevel.jpl.nasa.gov/ GISTEMP - GISS Surface Temperature Analysis data.giss.nasa.gov/gistemp/ :::FOR EDUCATORS::: NASA Wavelength nasawavelength.org/resource-search?qq=global+warming Climate Kids: What is Global Climate Change? climatekids.nasa.gov/climate-change-meaning/
