With Earth's temperature climbing in concert with rising emissions of carbon dioxide (and eight of the hottest years on record occurring in the last decade), we appear to have begun a vast, unplanned experiment with our planetary home.

The confused argument hinges on one data set — the HadCRUT 3V — which is only one of several estimates, and it is the global temperature record that exhibits the least change over the last decade.

A number of recent studies indicate that effects of urbanisation and land use change on the land - based temperature record are negligible (0.006 ºC per decade) as far as hemispheric - and continental - scale averages are concerned because the very real but local effects are avoided or accounted for in the data sets used.

«Many paleorecords record global temperature rises of 5 to 6 degrees Celsius in a decade or two, and I give some examples.

The record - setting temperatures of 2016 have seen a small push from an exceptionally strong El Niño, but they are largely the result of the heat that has built up in the atmosphere over decades of unabated greenhouse gas emissions — as the spiral graphic makes clear.

The key points of the paper are that: i) model simulations with 20th century forcings are able to match the surface air temperature record, ii) they also match the measured changes of ocean heat content over the last decade, iii) the implied planetary imbalance (the amount of excess energy the Earth is currently absorbing) which is roughly equal to the ocean heat uptake, is significant and growing, and iv) this implies both that there is significant heating «in the pipeline», and that there is an important lag in the climate's full response to changes in the forcing.

While global temperatures rose by about one - fifth of a degree Fahrenheit per decade from the 1950s through 1990s, warming slowed to just half that rate after the record hot year of 1998.

This comes at the end of the warmest decade of global average temperature on record.

We still don't expect each year to be warmer than the last due to the intrinsic variability («weather») in global mean temperature (around 0.1 to 0.2 °C), but at the current rate of global warming (~ 0.17 °C / decade), new records can be expected relatively frequently.

Climate scientists don't know where and when temperature and precipitation records will be broken, but they are confident that the next decade and especially century will have more records of all kinds broken than the last decade and century.

For July temperature in Moscow, we estimate that the local warming trend has increased the number of records expected in the past decade fivefold, which implies an approximate 80 % probability that the 2010 July heat record would not have occurred without climate warming.

Research to be published in the journal Geophysical Research Letters shows that over the past decade the number of record hot days has been double the number of record cold days: The research was carried out by scientists at the National Center for Atmospheric Research, Climate Central, The Weather Channel, and the National Oceanic and Atmospheric Administration, and examined temperature records going back to the 1950s.

Given that 1985 was the last year with temperatures below the 20th century average, and 2000 - 2010 was the hottest decade on record, it has become impossible to say for certain that any given storm is free from the influence of our warmed world.

And at last they have found a new one: they suggest that the difference in the temperature increase over land and the oceans during the last decades might be due to contaminations of the land temperature record — They call it an anomalous behaviour — ignoring that it corresponds fully to what is physically expected.

High - frequency associations (not shown here) remain strong throughout the whole record, but average density levels have continuously fallen while temperatures in recent decades have risen... As yet, the reason is not known, but analyses of time - dependent regional comparisons suggest that it is associated with a tendency towards loss of «spring» growth response (Briffa et al., 1 999b) and, at least for subarctic Siberia, it may be connected with changes in the timing of spring snowmelt (Vaganov et al., 1999).

In fact, Marohasy points out that a lack of rising temperatures for recent decades is so common in paleoclimate reconstructions that tendentious climate scientists have necessarily added heavily adjusted, hockey - stick - shaped instrumental records (e.g., from NASA GISS, HadCRUT) on to the end of the trend so as to maintain the visualization of an ongoing dangerous warming.

A problem with airports is that they are often in urban or suburban locations that have been built up in the past few decades, and the increase in global air travel has led to increased traffic, pavement, buildings and waste heat, all of which are difficult to remove from the temperature record.
