'That's because Earth's temperature is already rising, so any year with a boost from El Niño could easily break records. [How El Niño Causes Wild Weather All Over the Globe (Infographic)]
The warmest years in the past decade, 2005 and 2010, followed weak El Niño years, according to NASA temperature records.
This year's predicted El Niño
could increase global surface temperatures by 0.18 to 0.36 degrees Fahrenheit (0.1 to 0.2 degrees Celsius), depending on the intensity of the event, said Wenju Cai, a climate scientist at CSIRO Marine and Atmospheric Research, a government research organization in Aspendale, Australia.'
'Most of this stored ocean heat comes from sunlight, but the release adds to the overall rise in temperatures caused by global warming, Cai said. "There's no doubt the underlying trend is caused by greenhouse warming," he said.
"Usually, the increase occurs more toward the latter part of the El Niño, when there is a mini-global warming," said Kevin Trenberth, a climate scientist at the National Center for Atmospheric Research in Boulder, Colorado.'

The jury is still out on this. Are we likely to see more El Niños because of global warming? Will they be more intense? These are the main research questions facing the science community today. Research will help us separate the natural climate variability from any trends due to man's activities. We cannot figure out the "fingerprint" of global warming if we cannot sort out what the natural variability does. We also need to look at the link between decadal changes in natural variability and global warming. At this time we can't preclude the possibility of links but it would be too early to definitely say there is a link.'

So if increasing CO2 is causing greater frequency and severity - this coming El Nino should it occur should be greater than 1982 or 1987.
