My Fab Four Up-to-Date Climate Change Observations

The 'fab four' climate graphs by Dr. Andreas Schmittner: Global Ocean Heat Content; Recent Monthly Mean CO2 at Mauna Loa; Arctic Sea Ice Index; and Global Land and Ocean Temperature Anomalies.

Here are a few links to web sites that contain up-to-date crucial observations.

In my opinion one of the most important is ocean heat content. The reason is simple. The ocean’s heat capacity is enormous. It takes up almost all of the additional heat the Earth accumulated in the last decades. Here is the image and link:

Global Ocean Heat Content

I think the 0-2000 m figure is the most interesting because it shows that the Earth’s climate system has not stopped warming 10 or 15 years ago as some claim. The “global warming hiatus” does not exist.

My second favorite must be the Mauna Loa CO2 record. Image and link here:

C02 PPM at Mauna Loa, Feb. 2014.

http://www.esrl.noaa.gov/gmd/ccgg/trends/

The monthly mean data displayed there by default show that we almost hit the 400 ppm mark in May of 2013. No doubt that we will exceed it this spring.

Next: Arctic Sea Ice. The National Snow and Ice Data Center has this great interactive graphic, where you can click on individual years and compare to the average. Image and link here:

Arctic Sea Ice Extent

And for the final observation: Global surface temperatures. Image and link here:

Global and Ocean Temperature Anomalies

If you pull down the “Timescale” menu and select “annual” you’ll get the annual mean. Will 2014 hit a new record high?

It is worthwhile checking back once-in-a-while with these great web sites.

  • Those are four compelling charts that all are consistent in their signal. The Arctic Sea Ice graph does show that February 2014 sea ice formation has been exceptionally low. In the BAMS State of the Climate 2012 report slide summary. Slide 3 and 7 connect some of your identified charts to other data sets. On slide three, 12 trends are indicated, six are highlighted in red as indicative of record levels. In slide 7 upper ocean heat content and sea level rise are shown together.
