How do we know the Earths climate is warming? 1. The Global Surface Temperature is Rising 2. U.S. Surface Temperature is also Rising 3. Sea Level is Rising 4. Global Upper Ocean Heat Content is Rising 5. Northern Hemisphere Snow Cover is Retreating 6. Glacier Volume is Shrinking 7. U.S. Climate Extremes are Increasing The warming trend that is apparent in all of the independent methods of calculating global temperature change is also confirmed by other independent observations, such as the melting of mountain glaciers on every continent, reductions in the extent of snow cover, earlier blooming of plants in spring, a shorter ice season on lakes and rivers, ocean heat content, reduced arctic sea ice, and rising sea levels. ncdc.noaa.gov/indicators/
