Not exact matches

Last week Gavin Schmidt, head of NASA's Goddard Institute of Space Studies, estimated that the average global temperature in 2016 could range from about 1.1 °C above preindustrial to only slightly below 1.5 °C, based on GISS's temperature record and its definition of pre-industrial (other records and definitions vary).

GISS produces two estimates — the met station index (which does not cover a lot of the oceans), and a land - ocean index (which uses satellite ocean temperature changes in addition to the met stations).

The obvious answer (from someone who is indeed receptive to arguments for lower - than - consensus climate sensitivities) is that it was on a par with recent hot years because temperatures at US latitudes of the globe really weren't as much cooler in the 1930s / 1940s (compared to the present) than GISS / Hadley's best estimates (from often sketchy global coverage) suggest.

The difference between the HadCrut and GISS treatment of this problem is that HadCrut does not use those grid cells to calculate the global temperature anomaly while GISS interpolates / extrapolates from the few stations around the artic to infill temperature estimates for the grid cells where no «real» data is available.

There are 5 best - known global temperature estimates, surface data from GISS, HadCRU, and NCDC, and lower - troposphere estimates from RSS and UAH.

However, the CRU global mean combined land air / sea surface temperature estimates for Jan - Aug 2005 lag behind the 1998 annual mean estimate by 0.08 C (0.50 C vs. 58C for 1998) while GISS indicates a lag of 0.02 C.

GISS, HadCRU, RSS, and UAH represent the four organizations that publish online the global average temperature estimates.

GISS produces two estimates — the met station index (which does not cover a lot of the oceans), and a land - ocean index (which uses satellite ocean temperature changes in addition to the met stations).

I had attempted a similar project at the 3rd conference with my poster «Comparison of Climate Forecasts: Expert Opinions vs. Prediction Markets» in which my abstract proposed the following: «As an experiment, we will ask participants to go on the record with estimates of probability that the global temperature anomaly for calendar year 2012 will be equal to or greater than x, where x ranges in increments of 0.05 °C from 0.30 to 1.10 °C (relative to the 1951 - 1980 base period, and published by NASA GISS).»

I presume that a corresponding error would be carried forward into the final GISS estimate of US lower 48 temperature and that this widely used estimate would be incorrect by a corresponding amount.

If they do all over estimate, this would explain why the GISS II model overshot the temperature variations.

WMO - «Because the data with respect to in - situ surface air temperature across Africa is sparse, a oneyear regional assessment for Africa could not be based on any of the three standard global surface air temperature data sets from NOAANCDC, NASA - GISS or HadCRUT4 Instead, the combination of the Global Historical Climatology Network and the Climate Anomaly Monitoring System (CAMS GHCN) by NOAA's Earth System Research Laboratory was used to estimate s

The NASA Goddard Institute for Space Studies (NASA GISS) is one of the five groups that currently publish global temperature trend estimates from weather station records, i.e., they produce one of the curves we showed you at the start of this essay in Figure 1.

Dr Curry, the mean model surface temperature trend estimate is ~ 0.20 C / decade compared to Cowtan and Way ~ +0.17 C or GISS ~ +0.16 C (both attempting improved Arctic representation).

Or, one could say that the estimated GISS temperatures for 2013 are [+ or — degrees] compared to the estimated Hadcrut temperatures for 2013.

Perhaps we should go with NASA's Goddard Institute for Space Studies GISS Surface Temperature Analysis11 with it's estimate of warming almost twice as large?

Summing up: My question for sTeve is: why would you choose the GISS estimate of temperatures, which shows parts of the past decade as higher than 1998 and considerable average warming, over the other three monitoring agencies, which show much less or no warming for the decade?

My best estimate from looking at the history of climate is that; a) Temperatures have been rising since 1698 - 2 centuries before James Hansen plugged his Giss figures into the end of a long trend and claimed he was capturing the start of it.

From that link's words, the DMI «green line» IS the best way to consistently compare the daily estimate of NORTH areas of the arctic — those areas north of 70 latitude to 83 north latitude NASA - GISS extrapolates «surface» ground - based temperatures as far as 1200 km from where their land - based measurements were made from 60 - 70 latitude over the ever - greening (and darker) tundra and forests OUT to the open sea where where the arctic sea ice actually is present.

if GISS gets it this wrong in a modern country with a competent national weather service, why would anyone have confidence in all the temperatures that are «estimated or extrapolated» for areas like the artic?

Because the GISS analysis combines available sea surface temperature records with meteorological station measurements, we test alternative choices for the ocean data, showing that global temperature change is sensitive to estimated temperature change in polar regions where observations are limited.

Three of them are estimates of surface temperature, from NASA GISS (Goddard Institute for Space Studies), HadCRU (Hadley Centre / Climate Research Unit in the U.K.), and NCDC (National Climate Data Center).

«Because the data with respect to in - situ surface air temperature across Africa is sparse, a oneyear regional assessment for Africa could not be based on any of the three standard global surface air temperature data sets from NOAANCDC, NASA - GISS or HadCRUT4 Instead, the combination of the Global Historical Climatology Network and the Climate Anomaly Monitoring System (CAMS GHCN) by NOAA's Earth System Research Laboratory was used to estimate surface air temperature patterns»

If you compare HadCRUT, NCDC and GISS over the region where they all estimate temperatures (roughly 60S to 60N), they come out pretty near the same (there are still differences, but they're smaller).

I feel the same way about calling the global temperature estimates from the HadCru, GISS and NOAA surface statistical models «observations.»

The part about not «effecting» ocean temperature may be in error, too, with regards to the GISS estimate of global temperature.
