Sentences with phrase «flat temperature periods»

Not exact matches

Its a simple fact there were high aerosols through the middle of last century correlating with a flat period of temperatures quite well.

Given the decadal averages and the issue of what is meant by «the next» decade, Romm does have a point that the result of the paper could more clearly be described as representing «a period of flat global mean temperatures extending somewhat into the coming decade, following by a very rapid rise in temperature leaving the planet on its long - term trend line by 2030.»

B. Over the same time interval there have been periods during which the reported «Annual Temperature of the Earth (TOE)» has increased, others during which it decreased, and yet others, like the most recent 15 - 20 years over which it has remained statistically flat.

IMO ground could only be gained either through a prolonged period of flat temperatures / cooling forcing a revision of consensus assumptions, or through a genius taking climate science to another level.

But looking at the big picture shown in the graph I posted, I see quite few time periods where there were five or ten years of flat or declining temperatures (including several during the satellite era) very much like what we're seeing today.

simply look at three different periods: 1959 - 1975 and 1998 - 2008 with near flat or even cooling temperatures and 1976 - 1997 with increasing temperatures.»

The trend itself is (near) independent of temperature, simply look at three different periods: 1959 - 1975 and 1998 - 2008 with near flat or even cooling temperatures and 1976 - 1997 with increasing temperatures.

How can you explain that an extreemly temperature sensitive CO2 graph should have been so extreemly flat in the period 1920 - 40, when temperatures where not at all flat!

«If the surface temperature resumed the warming rate that we observed from, say 1977 through 1998, we would still go close to a quarter of a century without significant net warming because there's such a long flat period built into the record now.

Additionally, the observed surface temperature changes over the past decade are within the range of model predictions (Figure 6) and decadal periods of flat temperatures during an overall long - term warming trend are predicted by climate models (Easterling & Wehner 2009).

Now we have 10 years of flat temperature at the end of the time period from 1977 - 2007 which must drastically reduce the calculated sensitivity from the one calculated looking only at the first 20 years of data.

Linear trends are appropriate for the time period after 1990 where the data are described well by a linear trend plus interannual noise (that's why we show a linear trend for the satellite sea level in our paper), but they don't capture the longer - term climate evolution very well, e.g. the nearly flat temperatures up to 1980.

this 18 year flat period is an unqualified falsification of the central role of CO2 in earth temperature behavior.

The same for the period 2000 - current, where the temperature is essentially flat, but the CO2 levels increase faster and faster...

In other words, this prediction would seem reasonable if the nature of nature was linear and not Extremistan and we could count on a predictable continuation of the current flat - temperature period.

I would think that after about 17 years of an at least 30 year period of relatively flat temperatures, claims that «civilization as we know it» is ending would appear a little silly or that people would at least be embarrassed to repeat such claims.

The flat or decreasing decadal temperature outcome is not unprecedented, neither in the much - longer timespan periods of large overall global temperature rise we see historically nor in the GCMs.

Temperature has gone up in fits and starts over the 20th century; periods of relatively flat temperatures (circa 1945 - 1975, 1998 - 2013) punctuated by big increases (circa 1925 - 1945 and 1975 - 1998).

Earlier this year, a paper by Michael Mann - for years a leading light in the IPCC, and the author of the infamous «hockey stick graph» showing flat temperatures for 2,000 years until the recent dizzying increase - made an extraordinary admission: that, as his critics had always claimed, there had indeed been a» medieval warm period» around 1000 AD, when the world may well have been hotter than it is now.

Dr. Judith Curry recently compared five data sets of global temperatures and found that all but one show the warming trend has been essentially flat for various periods exceeding 10 years in length during the past 18 years.

Robinson also told WND it's interesting to be living in a period when carbon dioxide is rising, yet temperatures are flat or going down.

How many periods would there have been when our forebears could have fooled themselves into thinking that temperatures were flat, or even cooling, and there was nothing happening to the climate?

Edim, the ENSO index does show more red, lots of which is in that 1979 - 95 period when the OLS for UAH temperature anomalies is flat.

The flat period of temperature rise will be famous to future scientists.

Not an exact science, else we would have profitable fortune tellers in abundance, but does the 2000 - 2010 temperature «flat spot» occur as a slowing point on the long term rise from the LIA (perhaps to peak one or more 66 year periods later in 2050 - 2060, 2120 - 2130)?

People on this site understand very well that the 2014 temp report is not alarming and that temperatures are still remaining flat despite a large increase in green house gasses over that period.

«Incidentally, the Nino34 temperature anomaly is absolutely flat over the period from 1982 to present — there is only apparent atmospheric warming during this period due to the natural recovery from two major volcanoes — El Chichon and Mt. Pinatubo.»

How do you explain that in the last 63 years, that only about 20 years showed temperature rising above the 1940 level, and the last 10 to 16 (or whatever period you choose) it has been flat to down?

During this period, when the temperature started to warm something triggered a fast rise, which you can see in the flat area of the histogram.
