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.

However, at the increased levels
seen since the Industrial Revolution (roughly 275 ppm then, 400 ppm now; Figure 2 - 1), greenhouse gases are contributing to the rapid rise of our
global average temperatures by trapping more heat, often referred to as human - caused climate change.

You can also
see in this graph that the warming trend in the
global data for the low troposphere, if we consider the whole set of data, i.e. from the
average between 1980 - 1982 till now, with now meaning the
average of the last three years, the warming trend is, AT MOST, 0.115 ºC / decade (0.3 ºC in 26 years), but the graph is going down recently, so it should be even less.
Those extremes will come about more slowly than the rise of mean temperature, but I have

Interestingly, although the [Summary for Policy Makers] clearly talked about the projected
global warming being up to 6.4 degrees above 1980 - 1999
average (which is 6.9 degrees above pre-industrial), you often
see AR4 cited as suggesting that warming could be «up to 4 degrees,» which I think is partly a consequence of the way a key figure was presented.
This was one of the motivations for our study out this week in Nature Climate Change (England et al., 2014) With the

seen in the observations during 2001 - 2013.
A situation which you describe in the paper (
see Figures 3a, 3b, first full paragraph of page 461, that the reconstructed trends for the Peninsula are less than the
global average and yet you describe is as one of the most rapidly warming places on earth, that your Figure 4e has spatial differences compared with Supplemental Figure 1c and 1d or the image you linked to in comment 18), and which renders that spatial detail of the cover image difficult to interpret.
You can forecast what the
average effect of such would be, but if it is big enough to show up on the

Now I've
seen mentions that (strong) El Nino years will make the
global annual
average higher — e.g. 1998 was so warm partly because of El Nino, and that this is due to the fact that sub-surface warmer water is brought up and allowed to affect the air temperature.
Of course this is a
global average but in principle I
see no reason not to consider that some large percentage of the energy warming the tropical Pacific will be from «back radiation» (for which CO2 will be partly responsible) and thus not «direct from the sun.»

see http://www.andrewgunther.com/climate-change/#talks for details), and use the NASA / GISS dataset to discuss

Re 99: Although
global averages are quoted in almost every mass media story on climate change I've never

Let me
see if I got it right: (1) With GW we're not sure of getting much change in overall
global average precip, but when when it rains it pours... & floods, which also means on the flip side we would expect increasing periods of no precip (aka droughts), since the
global average precip is not changing.

In the entirely subjective opinion of a particular group of IPCC authors, it's «extremely likely» (95 % certain) that «more than half of the observed increase in
global average surface temperature from 1951 to 2010» was caused by human - generated greenhouse gas emissions (
see the bottom of p. 13 here).
As noted above, 1997 - 98
saw an exceptionally strong El Nino, producing a consequent temperature high that has only in recent years been equalled - hence it being a popular start - point for the «
