As we discussed at the time, those results were used to conclude that the Earth System Sensitivity (the total response to a doubling of CO2 after the short and long - term feedbacks have kicked in) was around 9ºC — much larger than any previous estimate (which is ~ 4.5 ºC)-- and inferred that the committed climate change with constant concentrations was 3 - 7ºC (again much larger than any other estimate — most are around 0.5 - 1ºC).

@ohwilleke, that estimate is larger than I would have expected, as I (maybe incorrectly) see myself as a minority (my thought is that most gun owners continue to be gun owners, thus there wouldn't be the 5 - 15 % group of previous owners).

The earthquake — estimated at magnitude 9.0 on the Richter scale — occurred in a total area much smaller than previous large earthquakes, such as the 8.8 Chilean earthquake last year, arguing that the slippage was much greater for the Japan quake, one of the four most powerful earthquakes on record.

This is more than double previous estimates and, if correct, places the Alamo crater as one of the largest marine impacts in the last 550 million years, conservatively larger than the well - studied Chesapeake Bay impact crater (about 35 million years old) on the eastern shore of North America.

In that, our results disagree with most previous estimates and suggest that the global inventory of anthropogenic CO2 in the Southern Ocean could be much larger than what is currently believed.»

Estimates of teacher effects on achievement gains are similar in magnitude to those of previous econometric studies, but the authors found larger effects on mathematics achievement than on reading achievement, and in low socioeconomic status (SES) schools than in high SES schools.

The SIM / SOLSTICE instruments on SORCE have reported much larger UV changes than previous estimates, and this has been widely questioned (see here for a previous discussion).

The actual prevailing view of the paleoclimate research community that emerged during the early 1990s, when long - term proxy data became more widely available and it was possible to synthesize them into estimates of large - scale temperature changes in past centuries, was that the average temperature over the Northern Hemisphere varied by significantly less than 1 degree C in previous centuries (i.e., the variations in past centuries were small compared to the observed 20th century warming).

For various reasons ozone loss estimates for the past winter are more difficult than usual and the uncertainties of the final analysis will remain larger than for most previous winters.

The new paper suggests that the contribution from Greenland was on the low end of the prior estimates, but has little effect on the estimated total sea - level change, which points to a larger Antarctic source than the previous best estimate.

Our reconstructed GMSL trend of 1.1 ± 0.3 mm ⋅ y − 1 (1σ) before 1990 falls below previous estimates, whereas our estimate of 3.1 ± 1.4 mm ⋅ y − 1 from 1993 to 2012 is consistent with independent estimates from satellite altimetry, leading to overall acceleration larger than previously suggested.

One is that the IPCC forcing central estimate is 40 % larger than that from CO2 alone since 1950 (due to other GHGs and possibly reduced aerosol impacts relative to previous reports), so if you are going to use CO2 alone, you should really add this other 40 % to match what has happened since 1950 and that is what they did.

«However, Fig. 15 and the associated uncertainties discussed in Section 3.4 show that long term estimates of time variable sea level acceleration in 203 year global reconstruction are significantly positive, which supports our previous finding (Jevrejeva et al., 2008a), that despite strong low frequency variability (larger than 60 years) the rate of sea level rise is increasing with time.»

«Second, in contrast to the previously reported slowing in the rate during the past two decades1, our corrected GMSL data set indicates an acceleration in sea - level rise (independent of the VLM used), which is of opposite sign to previous estimates and comparable to the accelerated loss of ice from Greenland and to recent projections, and larger than the twentieth - century acceleration.
