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.

The same holds for the specific global mean EIV temperature reconstruction used in the present study as shown in the graph below (interestingly, eliminating the proxies in question actually makes the reconstruction overall slightly cooler prior to AD 1000, which — as noted in the article — would actually bring the semi-empirical sea level estimate into closer agreement with the sea level reconstruction prior to AD 1000).

Further evidence of the crucial importance of El Niño is that after correcting the global temperature data for the effect of ENSO and solar cycles by a simple correlation analysis, you get a steady warming trend without any recent slowdown (see next graph and Foster and Rahmstorf 2011).

I've graphed PDO and ENSO against global temperature data numerous ways and my results agree with Mr. D'Aleo's for the most part.

As for F&R, I just overlaid the F&R ENSO global temperature influence graph over the top of the natural internal variability only graph 1B.

Perhaps the best way for regular folks like us to counter the damage done is that anytime Marcott et al is mentioned, to always refer to the Marcott et al graph as this version below, along with the quote from their FAQs since the uptick «is not statistically robust, can not be considered representative of global temperature changes»:

As I look at the global mean temperature trend for the 20th century, I see a cyclical pattern as shown in the following graph.

If you look at a graph of a trend and see a line flattening out you for a short period of time — as we have seen in the past with global temperatures — then you know that you're looking at the effects of noise in a trend.

The scientists» main approach was simple: to look at solar output and cosmic ray intensity over the last 30 - 40 years, and compare those trends with the graph for global average surface temperature.

If you used 1880 to 1909 as the base years for a global temperature anomaly graph, most of the data would be above zero.

The «hockey stick» graph was touted by global warming alarmists as evidence of rapidly rising temperatures and as justification for government action to curb carbon dioxide emissions.

The lines on the graph represent a central estimate of global average temperature rise (relative to the 1901 - 1960 average) for the two main scenarios used in this report.

I still laugh out loud every time I see a graph purporting to show the average global temperature to within a 1 / 10th of a degree for 1850.

On the Guardian's forums, you'll find endless claims that the hockey stick graph of global temperatures has been debunked; that sunspots are largely responsible for current temperature changes; that the world's glaciers are advancing; that global warming theory depends entirely on computer models; that most climate scientists in the 1970s were predicting a new ice age.

For detailed evidence with graphs see Relationship of Multidecadal Global Temperatures to Multidecadal Ocean Oscillations Ch.

The correct interpretation is that the global mean temperature (GMT), for the last 130 years, from 1880 to 2010, has oscillated like a pendulum between the upper and lower GMT boundary lines, with the global warming trend line as the neutral position of the pendulum, as shown in the following graph.
