Sentences with phrase «warming pause period»

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.

There are periods when other factors might temporarily slow that rise such as the much - discussed global warming «pause» of the last decade, but the overall connection is clear.

They suggest this «pause» in the acceleration of carbon dioxide concentrations was, in part, due to the effect of the temporary slowdown in global average surface warming during that same period on respiration, the process by which plants and soils release CO2.

So, within a period of a month or so, we learn, first, that the much debated global warming «pause» is real after all (regardless of what the cause might be, which remains uncertain), and second, that widely held assumptions regarding extreme weather events caused by AGW, such as droughts and flooding, are unfounded.

A corollary of the prediction that Co2 would take up to 20 years to rise above the noise of natural variation is that natural variation could conceivable cause a «pause» of up to 20 years, and so the recent short period with a lack of warming is totally consistent with Hansen's predictions.

The corrections have made period just before the notorious hiatus colder (~ 1980 to ~ 2000) and the pause period warmer.

It would provide a partial explanation for not only the «pause» but 1910 - 1940 warming (mostly natural), the 1940 - 1980 (cooling / static period offset by increasing (but lower) CO2 effects), and the 1980 - 1998 warm period (natural and ever increasing anthropogenic effects).

But the pause can be disproved by picking the right ten year period to show a «warming trend.»

That has never come close to occurring during our modern warm period, and the ongoing global warming pause suggests that is unlikely to begin happening any time in the foreseeable future, either.

2 October, 2017 — The Pacific Ocean has reached the end of a period of cooler temperatures, signalling the termination of the so - called pause in global warming.

And they analyse the double standards used when discussing the so - called «pause» as compared to an equally long period of rapid warming, which in fact deviated more from the long - term trend than the recent phase of slower warming.

1) This kind of study continues to reinforce the notion that natural cyclical changes in ocean to atmosphere energy transfers are a very signficant potential reason for both the pause (as the ocean has retained more energy) and part of the big warming during the 1976 - 1998 period.

Based on the same flawed reasoning to conclude an absence of a trend from the non-detectability of a trend in the limited data sample from 1997 to the end of 1994, I could claim a «global warming stop» or «pause» for that 16 - year period.

The report claimed that the «pause» or «slowdown» in global warming in the period since 1998 — revealed by UN scientists in 2013 — never existed, and that world temperatures had been rising faster than scientists expected.

Also, using the same cherry picking approach as used by «skeptics» for the recent time period, based on which they claim a «global warming stop» or «pause» because of lacking statistical significance of a warming trend, I even could claim a «pause» in global warming from 1979 to at least the end of 1997.

For example, see the whole «global warming pause» meme, which said that global warming had paused because the linear trend was statistically insignificant over some time period.

I can produce a similar figure for the recent 16 year period, for which the alleged «global warming stop», «pause», or «standstill» is asserted by «skeptics» or even by Judith Curry.

The lack of statistical significance for the recent 16 - year period is used as reasoning for the assertion of the «global warming stop» or «pause».

-- The figures reveal that from the beginning of 1997 until August 2012 there was no discernible rise in aggregate global temperatures — This means that the «pause» in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996

The 1998 - now period is warmer than it would have been if you plotted the 1970 - 1997 temperature, then plotted a pause.

This means that the «pause» in global warming has now lasted for about the same time as the previous period when temperatures rose, 1976 to 1986

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 mixingwarming (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 mixingWarming 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 mixingwarming 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 mixingwarming 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 mixingWarming 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 mixingwarming 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 mixingwarming to cumulative carbon emissions» «The sensitivity of the proportionality between temperature change and cumulative CO2 emissions to ocean mixing»

In an interview with me last year another of the authors, Prof Michael Mann, described the period of an alleged slowdown as the «faux pause», saying that «global warming hasn't stopped, even though you still hear those contrarian talking points.»

O.K., I didn't actually predict a pause in the warming but a possible period of cooling.

«A reduction in the rate of warming (not a pause) is a result of short - term natural variability, ocean absorption of heat from the atmosphere, volcanic eruptions, a downward phase of the 11 - year solar cycle, and other impacts over a short time period,» Cleugh says.

So it's quite understandable that — just as they tried to do with the «Medieval Warming Period» and also «the decline» (which proved so troubling to Michael Mann and his pals)-- the alarmists are doing their damnedest to write the «Pause» (or, if you will, «hiatus») out of scientific history.

According to a report in The Mail on Sunday, NOAA scientist Dr. John Bates has produced «irrefutable evidence» that the NOAA study denying the «pause» in global warming in the period since 1998 was based on false and misleading data.

In summary, your argument pointing to the lacking statistical significance of the temperature trend estimate for a time period is not sufficient empirical / statistical evidence or scientific justification for the claim that there was a «pause» of global surface / troposphere warming.

There was a period of unforced warming between 1925 and 1945, a Pause in forced warming from 1945 - 1975, and 1998 - 2013 (though rising aerosols may have caused some of the former Pause).

While the AMO has not changed much in the past 10 years, the strong increase in North Atlantic temperatures between 1970 and 2000 may have contributed to the rapid rise in global temperatures over that period, and the leveling - out of the AMO may help make the observed pause in warming more likely.

The data and the statistical analysis does not provide the evidence that the so called «pause», a time period with a lower trend estimate than the longer - term trend estimate, was more than just a short - term fluctuation around the median warming trend, mostly due to short - term unforced internal variability in the Earth system (and some contribution from decreasing solar activity and increased reflecting aerosols in the atmosphere, counteracting the increased greenhose gas forcing to some degree), like the «acceleration» over the 16 - year period from 1992 to 2007 (e.g., UAH trend: 0.296 + / - 0.213 (2 sigma) deg.

However, it is not just this pause in the warming that is puzzling, other problems include the absence of the tropospheric hot spot, the inability to describe the previous periods, e.g. the Medieval, the Roman, and the Minoan warm periods.

● That climate natural variability is powerful enough to fully compensate manmade global warming (if any) and long term pause (as observed since 1997) or even slight cooling periods as observed from 1880 to 1910 or from 1940 to 1970.

The least - squares linear - regression trend on the RSS satellite monthly global mean surface temperature anomaly dataset continues to show no global warming for 18 years 9 months since February 1997, though one - third of all anthropogenic forcings have occurred during the period of the Pause.

This means that the «plateau» or «pause» in global warming has now lasted for about the same time as the previous period when temperatures rose, 1980 to 1996.

Finally, the current so - called pause in temperature increase covers a period starting with one of the two largest known El Nino (short term warming) events known, and ends with two large La Nina (short term cooling) events.

How does this relate to the apparently predictable and patterned air temperature change recorded since 1880 (alternating 30 year periods of warming and pause in warming)?

I got an additional 15 minutes of blogosphere fame last year when I pointed out that according to CDIAC we had emitted a third of all human emissions since 1998, the start of the «pause» in the current warming period.
