GISS surface temperature - confidence intervals

AI Thread Summary
HadCRUT4 provides global surface temperature anomalies with confidence intervals, while GISS offers surface temperature data in tabular form without these intervals. Users are seeking sources for confidence intervals related to GISS data, as the available graphs do not provide this information. The GISS FAQ section addresses the accuracy of their results and may contain relevant insights regarding confidence intervals.

The HadCRUT4 global surface temperature anomalies in tabular form include confidence intervals.
The GISS surface temperature data is available in tabular text form here http://data.giss.nasa.gov/gistemp/tabledata_v3/GLB.Ts+dSST.txt
- but it doesn't include any confidence intervals.

Can anyone suggest where to find the confidence intervals? I found some graphs on their website but no data.
Thanks.

Look here http://data.giss.nasa.gov/gistemp/FAQ.html under Q.How accurate are the GISS results (tables, graphs)?
 

Thread 'Landslide, tsunami, seiche in Tracy Arm fjord, Alaska - 10 August 2025'

On August 10, 2025, there was a massive landslide on the eastern side of Tracy Arm fjord. Although some sources mention 1000 ft tsunami, that height represents the run-up on the sides of the fjord. Technically it was a seiche.

Thread 'Could an external cosmic body have influenced Earth’s geology?'

Hello, I’m currently writing a series of essays on Pangaea, continental drift, and Earth’s geological cycles. While working on my research, I’ve come across some inconsistencies in the existing theories — for example, why the main pressure seems to have been concentrated in the northern polar regions. So I’m curious: is there any data or evidence suggesting that an external cosmic body (an asteroid, comet, or another massive object) could have influenced Earth’s geology in the distant...
