In this post I set both UAH and GISS global temperature anomaly series to a common baseline period (1981-2010) and compare them. Even though the UAH series is satellite based and GISS series is station based, the series exhibit striking … Conti...

September 2011 Arctic Sea Ice Extent Forecast
In this post, I use a quadratic regression model to forecast the September, 2011 Arctic Sea Ice Extent. The model was developed with 1980 – 2010 data. Links to the R script, source data and how-to article on polynomial regression … ...
Assessing Climate Trends: Eyeball versus Regression
In a previous post, I showed the Lower Stratospheric Temperature Anomaly (TLS) Trends (link). A reader submitted the following comment: “The lower stratosphere temperature profile is essentially flat from ca. 1995 to the present. This approxima...
Climate Time Series In a Single CSV File
I am pleased to announce my CTS.csv file which includes 18 climate monthly time series in one easy to access csv file. This is part of my goal of having a user friendly way for do-it-yourself citizen climate scientists to … Continue reading ...
Volcanic Solar Dimming, ENSO and Temperature Anomalies
In previous posts I have shown plots of global temperature anomaly, volcano and Nino34 trends (here , here). In this post , I want to further explore the role of volcanic eruptions and Nino34 phases (El Nino, La Nina) on … Continue reading →
Climate Charts, Data and RClimate Scripts
While there are many online climate data resources, the source data files are in numerous data formats, presenting a challenge to climate citizen scientists who want to retrieve and analyze several climate indicators at the same time. I have been ̷...
RClimate: Converting 5 Global Temperature Anomaly Series to A Common Baseline
The 5 global land-ocean temperature anomaly (LOTA) series use different baseline periods, making direct comparisons between the series more difficult than it would be if each series had the same baseline period. This post shows how to convert the 5 ...
Nov 2010 Year-To-Date Global Temperature Anomaly 1st in 2 Series, 2nd in 3 Series: Update
This post shows the YTD global land – ocean temperature anomaly (LOTA) trends for the 5 major series through November, 2010 and how 2010 YTD ranks over the entire record for each series. The source data file link is provided. … Contin...
