See also the summary of the predictions for the future increase in temperature up to 2100. During this time, the Muir Glacier retreated more than 20 km (Picture from global warming art ).Įven if the global warming effects would convince mankind to stop emitting greenhouse gases, the global warming is expected to continue past 2100 because carbon dioxide (CO 2) has an estimated atmospheric lifetime of 50 to 200 years. The distance to the visible Riggs glacier in 2004 is ~3 km. Muir glacier, parts of which were greater than 65 meters thick in 1941, has retreated out of the image in 2004 (towards the upper left) as an effect of global warming. Glacier retreat of Muir glacier: Comparison photos of Muir and Riggs Glaciers in Glacier Bay National Park and Preserve, Alaska. As further effects of global warming, diseases like malaria are returning into areas where they have been extinguished earlier. Other effects of global warming include higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions. The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased (in addition, there has been a high correlation of hurricane power with tropical sea-surface temperature).Ĭhanges in temperature and precipitation patterns have also global effects on extreme weather events: They increase the frequency, duration, and intensity of floods, droughts, heat waves, and tornadoes. Amounts and patterns of precipitation are changing.Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.However they are causing a broad range of additional, secondary effects : Increasing global temperatures are the primary effects of global warming. More details and secondary effects of global warming : Rise of sea levels by at least 25 meters (82 feet) by the year 2100.Increase of temperature on the earth by about 3° to 5° C (5.4° to 9° Fahrenheit) by the year 2100.
There are two major effects of global warming:
