The ozone hole didn't cause global warming, but climate and the ozone hole are related in other ways.
In the 2015 edition of the State of the Climate report, climate and biology experts wrote about some dramatic impacts of warming on life in the ocean.
A record-smashing hurricane season in the central North Pacific. Water rationing in Puerto Rico. The biggest one-year jump in atmospheric carbon dioxide concentrations. These and more of 2015's extreme events had one thing in common: El Niño.
Sea level has been rising over the past century, and the rate has increased in recent decades as melting of glaciers and ice sheets has accelerated.
As of 2015, the warming effect of long-lived greenhouse gases in Earth's atmosphere had increased by approximately 37% compared to 1990.
Human activities, mainly burning fossil fuels, are increasing the concentration of carbon dioxide in our atmosphere, amplifying the natural greenhouse effect.

Answers to some of the questions that readers frequently ask NOAA experts about El Niño and La Niña.
NOAA's Climate Prediction Center monitors and issues outlooks for El Niño and La Niña using a 2-category (watch/advisory) alert system.
Records from the last five decades show that on average, spring snow is disappearing earlier in the year than it did in the past.
