Global warming is intensifying El Niño weather
As humans put more and more heat-trapping gases into the atmosphere, the Earth warms. And the
warming is causing changes that might surprise us. Not only is the warming causing long-term trends in heat, sea
level rise, ice loss, etc.; it’s also making our weather more variable. It’s making otherwise natural cycles of
weather more powerful.
Perhaps the most important natural fluctuation in the Earth’s climate is the El Niño process. El Niño refers
to a short-term period of warm ocean surface temperatures in the tropical Pacific, basically stretching from South
America towards Australia. When an El Niño happens, that region is warmer than usual. If the counterpart La Niña
occurs, the region is colder than usual. Often times, neither an El Niño or La Niña is present and the waters are a
normal temperature. This would be called a “neutral” state.
The ocean waters switch back and forth between El Niño and La Niña every few years. Not regularly, like
a pendulum, but there is a pattern of oscillation. And regardless of which part of the cycle we are in (El Niño or La
Niña), there are consequences for weather around the world. For instance, during an El Niño, we typically see
cooler and wetter weather in the southern United States while it is hotter and drier in South America and Australia.
It’s really important to be able to predict El Niño/La Niña cycles in advance. It’s also important to be able
to understand how these cycles will change in a warming planet.
El Niño cycles have been known for a long time. Their influence around the world has also been known
for almost 100 years. Having observed the effects of El Niño for a century, scientists had the perspective to
understand something might be changing.
The relationship between regional climate and the El Niño/La Niña status in climate model simulations of
the past and future. It was found an intensification of El Niño/La Niña impacts in a warmer climate, especially for
land regions in North America and Australia. Changes between El Niño/La Niña in other areas, like South
America, were less clear. The intensification of weather was more prevalent over land regions.
And this conclusion can be extended to many other situations around the planet. Human pollution is
making our Earth’s natural weather switch more strongly from one extreme to another. It’s a weather whiplash that
will continue to get worse as we add pollution to the atmosphere.
Fortunately, every other country on the planet (with the exception of the US leadership) understands that
climate change is an important issue and those countries are taking action. It isn’t too late to change our trajectory
toward a better future for all of us. But the time is running out. The Earth is giving us a little nudge by showing us,
via today’s intense weather, what tomorrow will be like if we don’t take action quickly.

A
climate changes in South America effects caused by El Niño/La Niña are not fully understandable by
weather experts further studies are yet necessary.
B
scientists are observing warmer climates caused by El Niño/La Niña effects and try to understand better
how the phenomenon is affecting Atlantic Ocean.
C
La Niña is the climate weather changing in South America and Australia regions switching the climate on
those regions from cold and wet to hot and dry climates.
D
United States of America is heading a group of experts in climate change to understand the effect of El
Niño/La Niña in its own country, especially southern region.
E
global warming is intensified by heat-trapping gases into the atmosphere through pollution produced
especially by vehicles and industries which are burning fossil fuel.
