Tracking JAXA Arctic Sea Ice Extent Trends
See my Arctic Update Page for daily updates on Arctic Sea Ice Extent Arctic Sea Ice Extent (SIE) follows an annual cycle, with maximum levels usually in March and minimum values in September. Many analysts use day-of-year charts to compare … Co...
Tracking Long Term and Recent UAH Channel 5 Anomally Trends
In this post I present combined long term and recent trend charts of UAH Channel 5 temperature anomalies using R’s figure inside figure capability. This approach provides a better picture of global temperature trends than UAH’s day-of-y...
UAH Channel 5 Anomaly Trends
Lucia at The Blackboard has on on-going bet where readers submit predictions of the monthly UAH anomaly, the April bet post is here. Lucia does some very interesting climate analysis, some of her charts, however, can give me a headache … Contin...
Climate Oscillations and GISS Temperature Anomaly Trends
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 
RClimate Script: Pacific Decadal Oscillation Trend
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 
Visualizing Arctic Sea Ice Extent Trends
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 Misreads Arctic Sea Ice Extent Trends
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 
RClimate Script: Global Mean Sea Level Trend by Month
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 
Tracking Climate Trends with RClimate Scripts and Links
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) ,
