Sentences with phrase «temperature estimates»

* The claim that 95 % of the greenhouse effect is caused by water vapor (this fallacy is the primary way he gets very low temperature estimates for reducing CO2).

It's in variations («anomalies») a base temperature — I'd start at the bottom of the chart to get that straight and also get the base temperature estimate.

The graphs compare the global mean temperature estimated by the models with that estimated from the data.

How does the water remain liquid at temperatures estimated at — 14 °C and — 15 °C, well below freezing?

Indeed, it is quite likely that neither of them are accurate temperature estimates!

Since these two time series represent largely independent mean temperature estimates for the same atmospheric layer, the strong correspondence between them is further proof that the fluctuations are real.

It results in much higher temperature estimates through the 1940s and 1950s with an impression of virtually all of the temperature increase taking place by 1940 and little change for the next 50 years.

As can be seen from Figure 1, all of these global temperature estimates give pretty much the same result.

We then converted these linear fits back into temperature estimates for each of the pressures measured by the balloons.

This requires reasonable temperature estimates and would need to be verified based on what is already know about the fluctuations from mapping and dating wood.

The first problem is that the proxy - based global temperature estimates do not actually agree with the thermometer - based estimates very well.

Only by including carbon cycle feedbacks and longer time periods than 100 years in your projections can you come up with realistic long - term temperature estimates.

The meat of the matter is why the different adjustment procedures don't agree and if there is any way to get accurate enough temperature estimates to make useful estimates of the accumulated energy.

The surface temperature estimates are biased high, showing more warming than is actually occurring.

Even if you get a reasonable temperature estimate you must have an accurate date.

We can compare that to what results from subtracting the average of surface temperature estimates from the average of satellite measurements:

The following graph shows annual average temperature estimates from Berkeley Earth and 5 other research groups that estimate surface temperature.

Richard Alley, a geoscientist at Pennsylvania State University, said some scientists have questioned the data set's accuracy and prefer using other ocean temperature estimates than the ones the researchers employed.

Our «Urbanization Bias» papers show that the global temperature estimates used by the IPCC are strongly biased by urbanization, particularly since the mid-20th century (summary here).

However, the combined evidence of the influence of natural variability on the unforced temperature estimate, the disagreement between different observational datasets on warming level, and the uncertainty introduced by an uncertain pre-industrial temperature baseline means that we can't be confident as the Millar paper suggests on what the current level of warming is, and that the balance of evidence suggests that the Otto warming estimate may be biased cold.

The main basis for the claim that there has been «unusual» global warming since the Industrial Revolution arises from the various global temperature estimates constructed from weather station records.

Temperature estimates derived from tetraether composition may be more representative of summer processes when temperatures are higher and soils have greater water content, promoting the facultative anaerobic bacteria that are hypothesized to synthesize tetraether lipids (Weijers et al., 2007).

After all, UAH has a history of being biased low, and other measurements of atmospheric temperatures estimate higher warming rates than in the UAH record.

Hansen's vested interest could explain why, as Goddard notes in his post, the GISS temperature estimates are consistently «adjusted» to be higher than the other agencies.

DMI recommend that the 2m air temperature data should not be compared with overall Arctic temperature estimates from other data sets, which generally cover a wider area (usually above 65N) where more land station data is available.

In addition, land stations are allowed to provide temperature estimates for ocean cells where no sea surface temperature is available - in practice, this means that coastal stations around the Arctic provide temperature readings for the pole.

The objective here is to show that there is no global temperature estimate which can lay claim to be the thoroughbred line.

-- To undertake his computations, which are supposed to indicate a strong correlation of surface temperature to the solar cycle, rather then use world wide temperature estimates (GISS, HadCRU ect...), he uses 5.
