Indeed, this dynamics suggests a major multiple harmonic influence component on the climate with a likely astronomical origin (sun + moon + planets) although not yet fully understood in its physical mechanisms, that, as shown in the above figures, can apparently explain also the post 2000 climate quite satisfactorily (even by using my model calibrated from 1850 to 1950, that is more than 50 years before the observed temperature hiatus period since 2000!).

Not exact matches

The deceleration in rising temperatures during this 15 - year period is sometimes referred to as a «pause» or «hiatus» in global warming, and has raised questions about why the rate of surface warming on Earth has been markedly slower than in previous decades.

It is that the rise of electricity and the power - station & «clean» domestic coal 1940 - 1970 may have cut black carbon more than is presently accounted for and thus with the renewed ramp - up of SO2 emissions in that period, more readily provide the cause of the 1940 - 75 temperature «hiatus».

Here are the pre - «hiatus» and «hiatus» periods in the major temperature records as well as the new Karl et al dataset.

Two things have changed in recent years — first, the temperature changes over the historical period are now more persistent, and so the trend in relation to the year - to - year variability has become more significant (this is still true even if you think there has been a «hiatus»).

A similar issue arises when we attempt to evaluate the so - called «hiatus» of the 21st century, where we clearly see a major slowdown in temperature increase compared with the previous 20 years, during a period when CO2 emissions were soaring.

There have been decades, such as 2000 — 2009, when the observed globally averaged surface - temperature time series shows little increase or even a slightly negative trend1 (a hiatus period).

When flatlining temperatures wreck your global warming agenda, refusing to rise after 18 + long years in hiatus, despite record human CO2 emissions over that same period, simply homogenise, adjust (tamper) with the data.

Surface warming / ocean warming: «A reassessment of temperature variations and trends from global reanalyses and monthly surface climatological datasets» «Estimating changes in global temperature since the pre-industrial period» «Possible artifacts of data biases in the recent global surface warming hiatus» «Assessing the impact of satellite - based observations in sea surface temperature trends»

Delegates debated at length to find the clearest language possible to explain that a claimed «15 - year hiatus» is based on a single variable (global mean surface temperature), too short a period of observation for climatic significance, and sensitive to the choice of the starting year from which a 15 - year period is calculated.

but that ENSO can still cause natural cooling for periods of a decade or more so that even though the man - made influence continues to cause warming, it is cancelled by ENSO cooling and results in a «hiatus» of global temperature increase:»

The near - linear rate of anthropogenic warming (predominantly from anthropogenic greenhouse gases) is shown in sources such as: «Deducing Multidecadal Anthropogenic Global Warming Trends Using Multiple Regression Analysis» «The global warming hiatus — a natural product of interactions of a secular warming trend and a multi-decadal oscillation» «The Origin and Limits of the Near Proportionality between Climate Warming and Cumulative CO2 Emissions» «Sensitivity of climate to cumulative carbon emissions due to compensation of ocean heat and carbon uptake» «Return periods of global climate fluctuations and the pause» «Using data to attribute episodes of warming and cooling in instrumental records» «The proportionality of global warming to cumulative carbon emissions» «The sensitivity of the proportionality between temperature change and cumulative CO2 emissions to ocean mixing»

But as they say in the main paper, the change in overall global surface temperature trend during the hiatus period is almost entirely due to the 0.064 °C SST trend change between ERSSTv3b and ERSSTv4.

The «hiatus» is a real tropospheric event, with temperatures flattening at the the warmest 10 years on instrument record, with the last year of that ten year period (2014) potentially being the warmest of all and potentially the warmest on record.

The slowdown or «hiatus» in warming refers to the period since 2001, when despite ongoing increases in atmospheric greenhouse gases, Earth's global average surface air temperature has remained more or less steady, warming by only around 0.1 C.

The most widely used metric of global warming — global surface temperatures — indicates that the rate of global warming has slowed drastically and that the duration of the hiatus in global warming is unusual during a period when global surface temperatures are allegedly being warmed from the hypothetical impacts of manmade greenhouse gases.

Omission of successively larger polar regions from the global - mean temperature calculations, in both tropospheric and surface data sets, shows that data gaps at high latitudes can not explain the observed differences between the hiatus and the pre-hiatus period....

It is far more reasonable to say that there was a steady temperature increase from the 19th century to the 1940s, followed by a 30 - 40 year hiatus, then a 30 - year period of increase to the end of the century.

The latest entrants to the hiatus argument are from the Swiss Federal Institute of Technology, known as ETH Zurich, and they define the years of global mean surface air temperatures between 1998 and 2012 as a «hiatus», a period when the Earth «seemed hardly to warm».

Using the New Karl, or better described as the ERSST v4, temperature series does indeed make the hiatus go away but not the significant slowdown in warming from the period 1976 - 1999 to the period 2000 - 2014.

Dr. Gerald A. Meehl — Nature Climate Change — 18th September 2011 «There have been decades, such as 2000 — 2009, when the observed globally averaged surface - temperature time series shows little increase or even a slightly negative trend1 (a hiatus period)....»

They identified at least three different definitions of any so - called hiatus, different judgments of the extent of the period under discussion and different starting points, and of course the problem of different datasets of global air surface temperatures.

The 1998 - 2008 hiatus is not the first period in the instrumental temperature record when the effects of anthropogenic changes in greenhouse gases and sulfur emissions on radiative forcing largely cancel.

``... a more interesting question as to whether the system as a whole continues to gain energy during a period of a so - called tropospheric «hiatus» in temperature gains.»

A study published Wednesday in Science Advances confirms once again that there was no global warming hiatus or cooling period during the past 20 years, an idea that had previously been raised in earlier assessments of sea surface temperature data.

Looking at the variability in earlier temperature trends five more years could still be easily accommodated as a combination of natural variability and persistent trend, but at the end of that period the forcing that has not been compensated by Planck feedback would be so large that further hiatus would be surprising.

As I might have said before, in IPPC - speak it would be «Although we can not give significance to such a short period of time (14 years), this lack of warming is exactly what we would expect if there were to be a 30 year hiatus» I look forward to next spring / early summer when the first two temperature records cross the 15 year mark of slight cooling.

Although the surface temperature prescription is limited to only 8.2 % of the global surface, our model reproduces the annual - mean global temperature remarkably well with correlation coefficient r = 0.97 for 1970 — 2012 (which includes the current hiatus and a period of accelerated global warming).

If the elderly in the UK are forced to burn books for warmth this winter shall we associate that with lack of preparation for a period of flat temperatures due to the AMO / PDO or what to expect for three to seven more decades of a «warming hiatus?»
