This automatically updated page has an embedded html window in which the numbers will appear. I'm planning to run the script at least once a day, at about 5.15 pm Japan time, when the JAXA ice numbers appear. It will check for the latest Had/UAH etc numbers. New numbers will appear bolded or colored. And the graphs will be updated.
This version has the additional ice datasets and facilities described here.
Temperatures anomalies in the tables are as stated by the providers, with different anomaly bases. They have been converted to the same base (1981-2010) for plotting.
There is a new style of ice plot - an active plot where you can magnify sections.
The temperature and ice windows each have a current table at the top, with more data further down. There is also a log of datafile reporting dates, as explained here.

Monthly global temperature anomaly dataHere is the latest global anomaly temperature data:
Here is the latest report from TempLS mesh weighted version:
Here are some plots of temperature indices in recent times, set to a common anomaly base (1981-2010)
|Major temperature indices - last 5 months |
|Major temperature indices - last 4 years |
Here is an active plotter for global temperature indices. You can vary the selection of plot data with the checkboxes. The legend is active; you can choose to draw linear regression lines, or to smooth the curves. You can also choose a new color by clicking on the color square next to the name. You can drag, stretch etc the plot - details are in this post
The plot also allows you to switch (toggle button "Trendback") to a mode which shows on the y-axis not the anomaly, but the trend from the x-axis time to the most recent data. All the same plotting facilities are there, except for regress.
Daily Reanalysis Temperature data
Here is the latest NCEP/NCAR reanalysis (see post) surface temperature (°C) anomaly area-weighted average for recent months, and for days of the current month. The anomaly base years 1994-2013.
Here is a WebGL active map of this year's daily temperature anomalies. It has the usual trackball facilities. To get a specific day, let the mouse hover over the colored squares on the right; each square is a day, and the text top right tells you where you are. Click when you have the day that you want. The black squares at the top will give you a month average map. Details are at this post.
Here is a tool for looking at daily Arctic temperatures. It is described in a post here. There is a lat/lon rectangle that you can manoeuver, and then press the "plot new" button to see a plot for that region of daily average temperatures (not anomalies), along with the 1994-2013 average. The domain is initially set to the region N of 80°.
Update 6/6 I added a zero line and fixed an error in longitude matching where the plot shown was actually for the same region displaced 15°W
NH and SH Sea Ice data
Here is the latest Arctic sea ice extent data. You can choose from JAXA Arctic Ice Extent, or from NSIDC NH or SH:
Here is an active polar plot of the Jaxa Ice extent data. Units are million sq km. You can click on the current region circle to get a magnification, or on any sector to see that part expanded. Clicking on the legend marks the year in dark; clicking on the central picture makes it go away. Details here.
