The main point is that just as surface temperatures has experienced periods of short term cooling during long term global warming, similarly the ocean shows short term variability during a long term warming trend.

This warming trend in the Pacific Ocean is on the tips of everyone's tongue when wishfully discussing the possibility of enough rain this winter to quench our state's historic drought.

If mean global temperatures trending significantly upward over the last 100 years isn't worrying enough for you, how about that giant piece of Antarctica that is about to crack off and sink into the ocean... I don't know how the existence of global warming is still a debate!

Given how much yelling takes place on the Internet, talk radio, and elsewhere over short - term cool and hot spells in relation to global warming, I wanted to find out whether anyone had generated a decent decades - long graph of global temperature trends accounting for, and erasing, the short - term up - and - down flickers from the cyclical shift in the tropical Pacific Ocean known as the El Niño — Southern Oscillation, or ENSO, cycle.

A very consistent understanding is thus emerging of the coupled ocean and atmosphere dynamics that have caused the recent decadal - scale departure from the longer - term global warming trend.

When I wrote «In either case, we see no evidence of any long term warming trend, in either the atmosphere or the ocean,» that should have read «long term warming trend due to CO2 emissions...» There may be some evidence consistent with long term warming in the oceans, but I can't see how that could be due to CO2, for reasons given above.

From what I see from the Global Historical Climatology Network (GHCN) of land temperatures and the Comprehensive Ocean - Atmosphere Data Set (COADS) of SST data, temperatures there were higher around the 1930's than now, and there is not much long term warming trend, except for the past few years.

«While these improvements in the land and ocean temperature record reveal a rate of warming greater than previously documented, ****** we also found that our computed trends likely continue to underestimate the true rate of warming.

While we might HOPE FOR THE BEST — that there will be a cooling trend (less sun irradiance, etc) to exactly counteract our AGW trend (even so there is the negative effects of CO2, even without the warming — ocean acidification, crop loss to weed, etc)-- we should then be trying to AVERT THE WORST with even more drastic GHG cuts.

To clarify my above comment, I was suggesting that the observed rise in ocean heat content would be substantial with or without the La Nina effect, representing primarily the persistence of a long term warming trend.

I have to raise an objection to the phrase «the only region of the world that has defied global warming» — that might be neglecting a certain area in the Pacific where England 2014 has identified a very obvious point where the «Pacific conveyor» was bringing in the last decade up a lot of cold water from the deep ocean and has possibly played a major role in the specific trends for that period.

The authors of the study said the change could be temporary, given the short span of observations, but it matches a slight but steady warming trend in the affected ocean regions and also matches a pattern scientists have predicted would occur under human - caused global warming.

Most simulations of future global warming trends show that northern Europe and the north Atlantic ocean will get colder over time, not hotter as global warming progresses.
