Michael Mann, a climate scientist at Penn State who created the famous «Hockey Stick» graph of global temperature records going back hundreds of years, said that the spiral graphic was «an interesting and worthwhile approach to representing the data graphically.»

I am not sure how anyone can look at James Hansen's graph of global temperature history in his 1988 presentation and say that there was a long term warming trend at that time.

It's the latest research in more than a decade of work producing a climate «hockey stick» — graphs of global or regional temperatures showing relatively little variation over a millennium or more and then a sharp uptick since the middle of the twentieth century (the blade at the end of the stick).

One way to look at the climate is that global mean surface temperatures have wandered up and down, to the left and the right, warmer and cooler, over the last thousand years, but have generally stayed a straight course, represented by the dashed line placed on the graph by the I.P.C.C. in 1990.

When I look at any of the graphs of global temperature I am struck by an impression of a very high degree of autocorrelation (indeed, tending towards I (1) behaviour)-- particularly given the inflection around the turn of the century that seems inconsistent with a deterministic trend.

When a temperature anomaly of ~ 0.1 degrees Celsius (the difference between 2015 and the previous global heat record of 2014 — please note the above graph is in Fahrenheit, not Celsius) can lead to such an extreme carbon feedback response, we know we can expect a lot more feedback - induced CO2 now that world leaders are about to seal a 3.5 degrees warming deal — if at least 2030 pledges are not raised before the start of COP21, the Paris climate summit.

Image at right: Graph of global annual surface temperatures relative to 1951 - 1980 mean temperature.

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

Reader Eric Worrall writes: I was playing with Wood For Trees, looking at the relationship between Pacific Decadal Oscillation vs global temperature (Hadcrut 4), when the following graph appeared.

The carbon dioxide continues to climb but the global temperature have stopped going up and look to be trending down... now look again at the Cloud cover % graph (graph 5) and you see the decline in cloud cover has stopped.

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.

It will just remain at a higher level of global temperature and CO2, if this graph is representative of what is happening.

Has anyone confronted any of these prestigious «science» associations, pointing out, hopefully at public meetings, that there are currently 1,056 studies (many produced after, and in spite of, Mann's hockey stick graph) which clearly demonstrate both the temperature amplitudes, durations, and global nature of both the MWP and LIA?

But when climate scientists looked at a graph of the rise of temperatures in the last 60 years, they saw — or thought they saw — a distinct drop in the rate of increase in global average temperatures in the last 15 years.

Climatologist Dr. Ross McKitrick, one of the authors and an Associate Professor at the University of Guelph, believes that the United Nations agency promoting the global temperature graph has made «false claims about the quality of its data.»

They included the following nifty graph, with the observed surface temperature but also the eventually expected temperature at the corresponding CO2 concentration (which they dub the» real global temperature»), based on different approaches to account for warming in the pipeline:

The climate is warming — and that means if you look at a graph of average global temperatures, you'll see an overall upward trend over the last 130 years.

... «This is a highly speculative and slight paper that produces a statistically marginal result by cherry - picking time intervals, resulting in a global temperature graph that is at odds with those produced by the UK Met Office and NASA.

This graph shows that even at the lowest range of climate sensitivity, future global warming will take us well beyond any temperature experienced during civilized human history.

By looking at the graphs of constant global average temperature and saying «Look, the problem doesn't get any worse!»

I recall more than one guest lecture at our physics department's Centre for Global Change Studies displaying a graph of spectral analysis of temperature histories, with data from multiple time scale sources including thermometer records, ice core data, etc..

And since you like «eye balling graphs» have a look at the latest hadcrut or nasa global temperature graph, and it should be obvious to even you the «pause» is a blip of about 6 years duration of flat temperatures, thus easily explained by natural variability.

Setting the radius at 250 km., and taking the first decade of Bart's graph, 1880 - 1890, the map reveals «global» mean temperature perforce excluded the whole of Central America, virtually all of South America and Africa, all of Thailand, Vietnam, Cambodia, Malaysia, Indonesia, and almost all of China.
