Sentences with phrase «warming average value»

Not exact matches

There are some caveats with their study: The global climate models (GCMs) do not reproduce the 1930 - 1940 Arctic warm event very well, and the geographical differences in a limited number of grid - boxes in the observations and the GCMs may have been erased through taking the average value over the 90 - degree sectors.

If long - term global warming is to be limited to a maximum of 2 °C elsius above preindustrial values, average annual per - capita emissions in industrialized nations will have to be reduced by around 80 - 95 % below 1990 levels by 2050.

One solution which has different assumptions than what is used to define the HadCRUT4 global values, would be to calculate the zonal means first and then area weight those — which assumes that missing data warms at the same rate as the local zonal average as opposed to the global means.

It stands to reason that the oceans haven't been that warm in a while but since the average temperature of the whole mass of water is so dependent on circulation (it's only the surface temperature that's constrained by its interactions with the atmosphere and space), I suppose a plausible history of that particular value would be very hard to reconstruct.

In order to make the trends comparable despite the different periods and CO2 increases, they were divided by the globally averaged warming trend, i.e. all values above 1 show an above - average warming (orange - red), values below 1 a below - average warming, negative values a cooling.

In the North Atlantic, the measured values differ markedly from the average global warming: the subpolar Atlantic (an area about half the size of the USA, south of Greenland) has hardly warmed up and in some cases even cooled down, contrary to the global warming trend.

My value of — 0,32 K may be warmer than your -0,37 K, because I use the trend values in 2008 to get the number, not an average value?

For example, anomalies are correlated over fairly large distances: If it was warmer than average in NYC this year, it was also likely warmer than average in Boston and Montreal and Philadelphia even though the actual average value in this different cities might be fairly different.

Each SCC estimate is the average of numerous iterations (10,000 in the EPA's assessment, which we reproduce here) of the model using different potential values for climate sensitivity (how much warming a doubling of CO2 will generate).

Clearly, to use a single value (the global average annual average surface temperature trend) to characterize global warming is a naive approach and is misleading policymakers on the actual complexity of the climate system.

Only over many (five or more in my judgment) decades do these variations average out well enough to make these temperature values potentially useful for the determination of an indicator for warming.

The figure shows (with colored circles) the value of the trend in observed global average surface temperatures in lengths ranging from 10 to 64 years and in all cases ending in 2014 (the so - called «warmest year on record»).

One should not forget that the «global warming» is an average value.

Nationally, the average minimum (low) temperature was 43.1 °F, the warmest on record, exceeding the previous value (42.9 °F in 2012) by about 0.2 °F.

Come to think of it, if he really believes the «doubled» warming projections from the MIT study that his is so keen on touting, he ought to man - up and proffer a 0.50 °C average temperature rise during the next decade as a reasonable 50 - 50 value.

While the trend is not statistically significant, the central value is positive, meaning the average surface temperature has most likely warmed over this period.

If this month is a warm month, than all other fill values in past years for this month get bumped up a little because this months warm observation increased the average over time.

This value of 375 CO2 - e is the actual forcing that is currently acting to warm the oceans, melt ice, and cause gradual upwards changes in average air temperature.

For example, a reported global value of +0.69 °C ± 0.09 °C indicates that the most likely value is 0.69 °C warmer than the long - term average, but, conservatively, one can be confident that it falls somewhere between 0.60 °C and 0.78 °C above the long - term average.

And thirdly, a simple empirical adjustment to the average of a large family of models, based upon observed changes in temperature, yields a warming range of 1.3 - 3.0 °C, with a central value of 1.9 °C.

Current models suggest ice mass losses increase with temperature more rapidly than gains due to increased precipitation and that the surface mass balance becomes negative (net ice loss) at a global average warming (relative to pre-industrial values) in excess of 1.9 to 4.6 °C.

To get an «average» temperature, scientists take the warmest and the coolest temperatures in a day, and calculate the temperature that is exactly in the middle of those high and low values.

Taken together, the average of the warmest times during the middle Pliocene presents a view of the equilibrium state of a globally warmer world, in which atmospheric CO2 concentrations (estimated to be between 360 to 400 ppm) were likely higher than pre-industrial values (Raymo and Rau, 1992; Raymo et al., 1996), and in which geologic evidence and isotopes agree that sea level was at least 15 to 25 m above modern levels (Dowsett and Cronin, 1990; Shackleton et al., 1995), with correspondingly reduced ice sheets and lower continental aridity (Guo et al., 2004).

These values are significantly lower than the average warming of 0.02 °C / year observed in the previous thirty years 1970 - 2000.

These values mean that while 2015 will be warmer than average, we can be quite certain that the year will not be Australia's warmest on record — which occurred in 2013 with a +1.2 °C anomaly.

... The equilibrium global average warming expected if carbon dioxide concentrations were to be sustained at 550 ppm is likely to be in the range 2 - 4.5 °C above pre-industrial values, with a best estimate of about 3 °C.»
