The agreement stipulates that warming be limited to between 1.5 degrees C (2.7 degrees Fahrenheit) and 2 degrees C (3.6 degrees F). It also stipulates that countries achieve net-zero greenhouse gas emissions in the second half of this century.

Cutting emissions would reduce the threat of sea level rise to coastal cities worldwide, with especially significant benefits for New York and other U.S. East Coast cities.

Global sea level rise is not cruising along at a steady 3 mm per year; it’s accelerating a little every year.

Precipitation variability — the swing from dry to wet and back again — will continue to increase across the majority of the world's land area as the climate warms.

An international team of scientists will head to the remote Southern Ocean for six weeks to study clouds.
