Shows monthly GISS Land & Sea Temperature Anomaly - C trend from 1880 until latest month available from NASA GISSTemp. Base period is 1951-1980.

Decadal means shown in blue steps and last monthly value highlighted in red. Decadal means show steep rise since mid 1970s.

Shows monthly satellite based RSS Land & Sea Temperature Anomaly - C from Nov., 1978 to last available month.

Annual  means are shown in blue steps and last monthly value highlighted in red.

Uses R's figure inside figure capability to show both the long term anomaly trend as well as the current month daily trend.

R script includes data retrieval, conversion of wide format table to long format, calculation of monthly averages and production of 2 figures in one chart.

Shows monthly temperature anomaly data for 5 major temperature L&O anomaly series: GISS, NOAA, Hadley, RSS and UAH. First 3 use station data, the last 2 use satellite based observations.

The CSV data file is updated monthly from source agency data files. All source agency data is downloaded so that any changes in source data will be reflected in the consolidated file.

The R script used to generate the consolidated file is available on request.

Shows monthly NOAA - NCDC monthly Sea Surface Temperature - C (SST) Anomaly trends, starting in 1880 to most current month.

Decadal means shown in blue steps and last monthly value highlighted in red.

Shows monthly global mean sea level trends of  NOAA's Laboratory of Satellite Altimetry global mean sea level data. The chart shows the missions (TOPEX, Jason-1, Jason-2)  by color code and highlights the latest monthly data point.

The seasonal signal has been removed and an inverted barometer has been applied. No glacial isostatic adjustment (GIA) has been made. The overall rate of increase is 2.9  mm/yr. GIA estimates are in the 0.2 - 0.5 mm/yr range. 

This RClimate script requires user to download and save NetCDF file to own PC. Make sure to adjust source data file link in R script to properly locate the data file on your PC.

Shows monthly global mean sea level trends of  University of Colorado - Boulder's satellite based data. Source data has not been updated since Sept., 2009. I will resume updating when source data is updated.

Chart shows the monthly change in mean sea level in red, 60-days smoothing value in blue and overall trend in green. The overall rate of increase is 3.1 mm/yr, with a +- error band of 0.4 mm/yr. 

Shows monthly CO2 (ppmv). Data from 1958 to last available month.

Last monthly value highlighted in red.

Shows NASA Solar Radiation & Climate Experiment (SORCE) Mission Data from 2/25/03 to present. Data updated weekly.

Shows NOAA's weekly trend in Nino 3.4 SST anomalies from January, 1990 to most recent week. Data reflects week centered on Wednesdays.

Periods with negative anomalies (La Nina like conditions) are shown in blue and periods with positive anomalies (El Nino like conditions) are shown in red.

Most recent reading is highlighted in black.

Downloads and plots University of Washington, Joint Institute for the Study of  Atmosphere and Ocean (JISAO)   monthly Pacific Decadal Oscillation (PDO) from January, 1900 to latest available month at time script is run.

Negative PDO months are shown in light blue and positive months are shown in pink. The most recent reading is highlighted in red.

The title and legend include the latest data month.

Shows NASA GISS temperature anomaly by latitude zone for 2000-2009 compared to baseline period (1951-1980).

Chart demonstrates significant Northern Hemisphere temperature anomaly increase with increasing latitudes. This means that Arctic regions are warming much more rapidly than the global mean.  While the global mean temperature anomaly increased 0.6 C in 2000-2009, the Arctic region anomalies increased nearly 1.8 C.

Retrieves JAXA daily Arctic Sea Ice Extent (SIE) csv file, plots 2007 and 2010 trends, highlights the maximum and current values for both series, calculates the decline rate for selected time periods and displays as table in plot.

Shows National Snow and Ice Data Center's (NSIDC) monthly Arctic Sea Ice extent trends in millions of square kilometers from 1979 to latest month.

Arctic sea ice extent includes areas with at least 15% sea ice concentrations.

Since sea ice extent varies seasonally, the chart shows the trend for each month. The latest month trend shown is shown in red. All months show declining sea ice extent, which is consistent with polar amplification, rising SSTA and rising global mean temperature anomaly trends.

Shows JAXA daily Arctic Sea Ice extent trends in millions of square kilometers from 2002 to latest month.

Arctic sea ice extent includes areas with at least 15% sea ice concentrations.

Since sea ice extent varies seasonally, the chart shows the trend for the current month for each year from 2002 to the present.  The latest daily reading is shown in red for the current year and previous years.

The University of Illinois at Urbana Champaign (UIUC)'s The Cryosphere Today (link) tracks Arctic sea ice extent and area on a daily basis, They maintain a chart called of daily sea ice area anomalies extending back to 1979. They call it the Tail of the Tape.  Since it is so long, it can be difficult to read (link).

I have developed a similar chart that displays in a single window so that readers can see the entire record in one glance. While the Cryoshpere Today gives more detail, I think my chart gives a better overview of the long term SIA anomaly trends.

This series constructs monthly file of GISS anomaly, PDO,AMO and ENSO data series and performs detailed analysis of the consolidated data file.
