A key his point in former us vice-president al gore"s famous documentary. Warming is unequivocal (evidence temps, melting, sea level rise) World temperatiures could rise by between 1. 1 and 6. 4 degrees celsius during the 21st century. Sea levels will probably rise by 18 to 59 centimeters (7. 1-23in) >90% chance there will be more frequent warm spells, heat waves, and heavy rainfall. >66% there will be and increase in droughts, tropical cyclones, and extreme high tides.
