In this post, I examine the combined impacts of Pacific Decadal Oscillation (PDO), Atlantic Multidecadal Oscillation (AMO) and El Nino – Southern Oscillation (ENSO) on the long-term GISS Land and Ocean Temperature Anomaly (LOTA) trend. Introduction Professor Don Easterbrook of … Continue reading 
This RClimate Script lets users retrieve and plot the monthly and moving average Pacific Decadal Oscillation (PDO) data from the University of Washington’s JISAO website. The script retrieves the PDO data from January, 1900 until latest month available at time … Continue reading 
Reader GH sent me an e-mail asking about a previous Arctic sea ice extent trend post (click). GH asked …. “Why is there such a difference between this type of representation and the chart at link ? What you’ve written … Continue reading 
Meteorologist Joe Bastardi recently made a video asking “…how the heck does it get this warm and yet we are back to normal global sea ice extent in the Northern Hemisphere?”. In this post I show how Joe misread the … Continue reading 
This RClimate Script lets users read a NetCDF file and plot the latest satellite altimetry based global mean sea level data from 1993 to the latest completed month. The trend chart shows NOAA’s Laboratory for Satellite Altimetry altimeter global mean sea level with the seasonal signal removed and inverted barometer. I will add this chart 
Some of my visitors may have noticed that I have added a new Climate Images page and have been adding climate data images to my right side panel. So far, I have 6 trend charts, 4 map images, 1 photo image and 1 data value showing the CO2 concentrations, recent total solar irradiance (TSI) , 
This RClimate Script lets users retrieve and plot the latest data on Arctic Sea Ice Extent trends by month from 1979 to latest completed month. The trend chart shows National Snow and Ice Data Center’s (NSIDC) monthly Arctic Sea Ice extent data. Arctic Sea Ice Trend by Month I’ve discussed the Arctic sea ice extent 
This RClimate Script lets users retrieve and plot the latest data file on monthly global RSS temperature anomaly data based for the lower troposphere. The trend chart shows monthly and annual anomalies since 1979. RSS Temperature Anomalies – Lower troposphere I’ve discussed RSS temperature anomalies in this earlier post. Here’s Remote Sensing Systems (RSS) global 
This RClimate Script lets users retrieve and plot the National Climatic Data Center’s monthly Sea Surface Temperature (SST) Anomaly dat series . Links to the NCDC data file and my RClimate script are included. Users can run my script with a simple R source() statement. NCDC SST Anomaly I’ve discussed the Hadley SST anomaly trends 
This RClimate Script lets users retrieve and plot the weekly NOAA NINO 3.4 SST anomaly data for 1990 to the most recent value. Links to the NOAA data file and my RClimate script are included. Users can run my script with a simple R source() statement. NINO 3.4 SST Anomaly I’ve discussed ENSO and NINO
