So the report notes that the current «pause» in new global
average temperature records since 1998 — a year that saw the second strongest El Nino
on record and shattered warming records — does not reflect the long - term trend and may be explained by the
oceans absorbing the majority of the extra heat trapped by greenhouse gases as well as the cooling contributions of volcanic eruptions.

Ray, I think Lee Grable's point is important: The fact that we use the term «global
temperature» to mean the
average temperature on a two - dimensional surface rather than the three - dimensional
ocean plus land plus atmosphere system of the earth has the potential to allow confusion.

My amateur spreadsheet tracking and projecting the monthly NASA GISS values suggests that while 2018 and 2019 are likely to be cooler than 2017, they may also be the last years
on Earth with global

ocean surface
temperature anomaly below 1C above pre-industrial
average (using 1850 - 1900 proxy).
However their predictions are about much more than just the
average near - surface air
temperature, they are mainly focused
on how heat mixes into the
ocean and how that affects the rise in surface
temperature as CO2 is doubled over 100 years.
During the period 1992 - 2000, the
average sea - surface
temperature of the Indian
Ocean increased by approximately 0.25 Celsius, this may be the cause of an increased monsoon strength here (or more hurricanes
on other places)...
It stands to reason that the
oceans haven't been that warm in a while but since the
average temperature of the whole mass of water is so dependent
on circulation (it's only the surface
temperature that's constrained by its interactions with the atmosphere and space), I suppose a plausible history of that particular value would be very hard to reconstruct.

It's important to note that a substantial short - term influence

There is virtually universal agreement that
average hurricane intensity
on Earth is a straightforward function of
ocean - atmosphere
temperatures; thus, rising SSTs will inevitably mean more intense hurricanes.
So, although each molecule of CO2 that escapes from the
oceans will,
on average, be back in the
ocean again in five years time, if the sea surface
temperature rises the increase in the atmospheric CO2 will remain.
But even when carbon dioxide does make its way out of the atmosphere, Earth's natural systems can release other carbon dioxide molecules that were previously stored in the
oceans / land back into the atmosphere, making the full effect of carbon dioxide emissions
on surface
temperatures much longer than this 5 - 200 year
average.
«As a coastal city located
on the tip of a peninsula, San Francisco is vulnerable to sea level rise, and human activities releasing greenhouse gases into the atmosphere cause increases in worldwide

In 2005, during the hottest
average decade
on record, 8 low - wind conditions known as «the doldrums» combined with very high
ocean temperatures to cause massive coral bleaching in the Virgin Islands.9 This was followed by a particularly severe outbreak of at least five coral diseases in the Virgin Islands, resulting in a decline in coral cover of about 60 percent.9 There is some indication that higher
ocean temperatures — between 86 and 95 degrees Fahrenheit (30 to 35 degrees Celsius)-- promote optimal growth of several coral pathogens.9 Other research showed that elkhorn coral post-bleaching had larger disease lesions than unbleached specimens, suggesting that bleaching may increase the corals» susceptibility to disease.9, 10
Temperatures over land and
ocean have gone up 0.8 ° Celsius (1.4 ° Fahrenheit),
on average, in that span:
This February's sea surface
temperatures were 1.46 degrees above

to be consistent, either we should have 100 points measuring the
temperature on a specific hour of the day
on mountains and in the
ocean, and no
average world
temperature, or we should do the same with CO2, measure high for the day, low for the day,
average, and make a global
average from many regions, and then define an anomaly
on the same interval as the
temperature anomaly in order to be consistent.
Air
temperatures at 925 millibar (about 3,000 ft above the surface) were mostly above

However, the critical threshold R C is independent of ɛ, and thus the calculation depends only
on relatively robust

Figure 5.3 shows the linear trends (1955 to 2003) of zonally
averaged temperature anomalies (0 to 1,500 m) for the World
Ocean and individual basins based
on yearly anomaly fields (Levitus et al., 2005a).
Since 4C is about the
average of the deep
ocean, more cooling
on one side or the other of the convergence zone changes the
average temperature of the sinking water.
The Arctic
Ocean's surface
temperature and salinity vary seasonally as the ice cover melts and freezes; [4] its salinity is the lowest
on average of the five major
oceans, due to low evaporation, heavy fresh water inflow from rivers and streams, and limited connection and outflow to surrounding oceanic waters with higher salinities.
Christy is correct to note that the model
average warming trend (0.23 °C / decade for 1978 - 2011) is a bit higher than observations (0.17 °C / decade over the same timeframe), but that is because over the past decade virtually every natural influence
on global
temperatures has acted in the cooling direction (i.e. an extended solar minimum, rising aerosols emissions, and increased heat storage in the deep
oceans).
