This winter, El Niño is bringing an unprecedented shift in rain patterns.
Global warming and the intense El Niño currently taking place could be prolonging the longest global coral die-off on record.
El Niño may be causing the spread of the dengue virus.
There won't be two more weeks of winter this year. Punxsutawney Phil did not see his shadow, which means that were in for an early spring. With El Niño, though, we shouldn't be all that surprised; temperatures are heating up-and quickly.
The California drought is still taking its toll. Now, scientists have announced that tens of millions of trees are in danger from this dry spell.
It's definitely not a white Christmas this year. You may have noticed that it's positively warm this holiday season, even in places like the east coast of the United States. Now, we're telling you exactly why that is.
Why is it so warm this winter? It could have something to do with El Niño. Scientists have announced that the strongest El Niño event since 1997-98 is currently unfolding in the eastern equatorial Pacific.
The year 2015 may be the warmest on record. Scientists have found that a combination of a Strong El Niño and human-induced global warming may just make 2015 the hottest year yet.
In a study at the University of Montana, researchers documented global connections between El Niño events and drought over a time period of 32 years.
California may be experience double the amount of severe droughts and floods later this century. The weather patterns El Niño and La Niña could play havoc on local ecosystems in the region.
Every two to seven years, an unusually warm pool of water develops across the eastern tropical Pacific Ocean to create a short-term climate change event. Known as El Niño, this event is now being studied as never before by NASA scientists.
