• Sea levels are rising due to thermal expansion of the ocean, in addition to melting of land ice.
• Amounts and patterns of precipitation are changing.
• The total annual power of hurricanes has already increased markedly since 1975 because their average intensity and average duration have increased.
• Changes in temperature and precipitation patterns increase the frequency, duration, and intensity of other extreme weather events, such as floods, droughts, heat waves, and tornadoes.
• Higher or lower agricultural yields, further glacial retreat, reduced summer stream flows, species extinctions.
• Diseases like malaria are returning into areas where they have been extinguished earlier.
