Rising Sea level

Sea level measurements from 23 long tide gauge records in geologically stable environments show a rise of around 20 centimeters (8 inches) per century, or 2 mm/year.

3. Seasonal temperature change.

•Global temperature increases aren’t spread evenly around the globe •Heat wave and extreme cold.

•Decrease in number of extreme cold days, thereby lengthening the season.

•Increases in number of extreme hot days.
