Are El Niños related to Global Warming?
El Niños are not caused by global warming. Clear evidence exists from a variety of sources (including archaeological studies) that El Niños have been present for hundreds, and some indicators suggest maybe millions, of years. However, it has been hypothesized that warmer global sea surface temperatures can enhance the El Niño phenomenon, and it is also true that El Niños have been more frequent and intense in recent decades. Recent climate model results that simulate the 21st century with increased greenhouse gases suggest that El Niño-like sea surface temperature patterns in the tropical Pacific are likely to be more persistent.

Whether El Niño occurrence changes with climate change is a major research question.
Not really. Though they are related to global mean temperatures. The fact that the last 2 years haven’t been No 1 & 2 on the all time list is often trotted out by deniers as proof that global warming doesn’t exist. This is rubbish as the top 15 warmest years on record have all been since 1990, and the 00’s are currently 0.2 degrees warmer than the 90’s. Yet deniers ignore this. El Nino leads to warmer temperatures, La Nina to lower, we are currently under the influence of La Nina so global temperatures willl be lower. That is short term WEATHER, not long term CLIMATE CHANGE. See http://www.metoffice.gov.uk/corporate/pr…
