While natural climate
variations like El Niño
do affect the frequency and severity of heat waves from one year to the next, the study suggests the increases are mainly linked to long - term changes in
sea surface temperatures.
But it
does say; «Natural climate
variations, which tend to involve localized changes in
sea surface temperature, may have a larger effect on hurricane activity than the more uniform patterns of global warming...»
El Ni o an irregular
variation of ocean current that, from January to February, flows off the west coast of South America, carrying warm, low - salinity, nutrient - poor water to the south;
does not usually extend farther than a few degrees south of the Equator, but occasionally it
does penetrate beyond 12 S, displacing the relatively cold Peruvian current; usually short - lived effects, but sometimes last more than a year, raising
sea -
surface temperatures along the coast of Peru and in the equatorial eastern Pacific Ocean, having disastrous effects on marine life and fishing
This
does not appear to be indicative of anthropogenic influences, but rather natural
Sea Surface Temperature variations.
Even while identifying some of the observed change in climatic behaviour, such as a 0.4 C increase in
surface temperature over the past century, or about 1 mm per year
sea level rise in Northern Indian Ocean, or wider
variation in rainfall patterns, the document notes that no firm link between the

That is Spencer's point, that the all of the
temperature change
does not appear to be dependent on
sea surface temperature, ENSO
variations.
