Simple Science 2: The World of Climate

Raymond of RiC-Communications  studio commented on a recent post and made an offer to share here some graphics on CO2 for improving public awareness.  He has produced 12 interesting slides which are presented in the post Here’s Looking at You, CO2.  This post presents the six  charts he has so far created on a second theme The World of Climate Change.  I find them straightforward and useful, and appreciate his excellent work on this. Project title is link to RiC-Communications.

This project is The World of Climate Change

Infographics can be helpful, in making things simple to understand. Climate change is a complex topic with a lot of information and statistics. These simple step by step charts are here to better understand what is occurring naturally and what could be caused by humans. What is cause for alarm and what isn’t cause for alarmism if at all. Only through learning is it possible to get the big picture so as to make the right decisions for the future.








This project will explore information concerning how aspects of the world climate system have changed in the past up to the present time.  Understanding the range of historical variation and the factors involved is essential for anticipating how future climate parameters might fluctuate.

Update with 3 new slides: Historic Climate Cycles (glaciers added)

For example:

The Climate Story (Illustrated) looks at the temperature record.

H20 the Gorilla Climate Molecule looks at precipitation patterns.

Data vs. Models #2: Droughts and Floods looks at precipitation extremes.

Data vs. Models #3: Disasters looks at extreme weather events.

Data vs. Models #4: Climates Changing looks at boundaries of defined climate zones.

And in Addition

Note that the illustration #10 assumes (as is the “consensus”) that doubling atmospheric CO2 produces a 1C rise in GMT (Global Mean Temperature).  Even if true, the warming would be gentle and not cataclysmic.  Greta and XR are foolishly thinking the world goes over a cliff if CO2 hits 430ppm.  I start to wonder if Greta really can see CO2 as she claims.

It is also important to know that natural CO2 sources and sinks are estimated with large error ranges.  For example this table from earlier IPCC reports:

Since the Statue of Liberty features in the sea level graphic, here are observations from there


Below are some other images I find meaningful, though they lack Raymond’s high production values.

    Dear Ron, Wow that was fast.
    After reading on the court case here in Switzerland, and Justice Wept, I’ve grown a little concerned that things are going to get out of hand. This was closely followed by an attack on Roger Federer to end his sponsorship by Credit Swiss Bank. These attacks won’t stop and I could imagine that they will go after other fish in the ocean. The movement is out of hand … So if you notice that I will be flying under the radar, please understand I’ve got a small business to run 😉

      Thanks Raymond for all that you have done. I appreciate your perceptions of what is informative and answers questions that come to your mind. I have been at this for several years and can get lost in the forest of sub-topics. So I look forward to your future creativity, whenever and however it appears.

        I was a little knocked out after this whirlwind of intense searching and researching. I had so much data in my head that I was starting mix things between projects. This alone got me thinking I’ve gone down deep into the rabbit hole.

        My first thoughts on this adventure is that considering all the data we’ve posted (it’s just the tip of the iceberg) I’ve found very little evidence to support this massive over reaction to theme. The whole thing is on thin ice, very thin ice.

        So, the adventure continues and I hope to get going on some more cool charts. There are so many to choose from. A treasure trove of possibilities!

        Cheers R

    I am very interested in the CO2/Temperature graph for the last 30 million years but i’d like to get a reference before posting. Facebook “fact checkers” tear down anything questioning the global warming orthodoxy but having references helps sell the point.


    • Ron Clutz · January 22, 2020

      Paul, as the slide indicated, it comes from a German climatologist Christian Dietrich Schonwiese. It comes from a site called They’re an interactive dinosaur museum in Canada.

      This looks like the original

      Looking at just the historical picture, shown in the graph above, we can see that global warming has happened many times before in human history. We’ve had the Minoan Warm Period, the Roman Climate Optimum, and the Medieval Warm Period in addition to the current warm period (Dansguard et al., 1968; Schönwiese, 1995; Keigwin, 1996). Note the steepness of the rise in temperature at the beginning of the Minoan warm period. This rate of warming far exceeds that of the current warm period. Huang et al. (1997) determined that the depiction of the Medieval Warm Period in this graph may be somewhat conservative. According to their study of 6000 boreholes worldwide, the global mean temperatures of the Medieval Warm Period dwarf the changes of the Twentieth Century.


    • Ron Clutz · January 22, 2020

      Whoops. That wasn’t the slide you wanted. The 30 million year slide came from Bill Illis and is based on ocean sediment proxies. Explanation is here:
      and here:
      There are d18O isotopes which have been dated going back all the way to 2.6 billion years ago. In total, there are 40,000 dated dO18 proxies covering the periods back to this time. 40,000 reliable proxies is more than enough to make a call about this history.

      Here are the temperature estimates and all of the CO2 estimates over the last 40 million years (the data used in the paper are in this chart but I am using all the reliable numbers that there are, so rather than 8 data points, there is a total of 16,000 datapoints here between temps and CO2).”

    Hi Ron
    I just added a new chart, it’s “under review” still, have to check everything on last time. Cheers and have a nice weekend. R

    World of Climate Change
    600 million years of temperature change and atmospheric CO2
    (This could be a possible chart for the Climate story)

    P.S. The list of other charts are all interesting.


    • Ron Clutz · January 24, 2020

      Thanks Raymond. Looks good (an extra 0 on the 100 M marker) This is an interesting variation on this info
      I also like references to Scotese and Bernier as sources of temperature and CO2 estimates (both above reproach).


      • Raymond · January 25, 2020

        Hi Ron
        So, I’ve updated the chart for 600 million years of temperature change. Thanks for seeing the mistake, it’s corrected. I also did some optical adjustments to the colors so it will just a little better.

        What concerns me more at the moment is that the levels of CO2 have been so low in the last couple of million years. Any lower and we’d be close to a global extinction of all life forms. It’s kind of scary that so many people truly do not understand how important CO2 is for the survival of all life forms on this planet. Ray


      • Ron Clutz · January 25, 2020

        Good work. I do think the slide belongs in the CO2 set as a companion to the one on CO2 levels.


      • Raymond · January 26, 2020

        Hi Ron.
        I added the Chart 600 million years… to “The World of CO2” It will appear in both sets of charts at the moment. I remove it form The World of Climate Change when I have a few more charts.
        Cheers R.


  5. Broadlands · September 21, 2021

    I think it is important to distinguish between Northern Hemisphere temperatures and Global temperatures when referring to 15°C. NASA/GISS used to report global temperatures using a 1950-1980 base period reference of 59°F (15°C). They now keep the same base period but have lowered all the temperatures within it to agree with NOAA’s 20th century mean of 14°C. That makes a big difference in the long term trend.


    • Ron Clutz · September 21, 2021

      Yes, it does make a trend difference when you lower the past in relation to the present.


      • Broadlands · September 21, 2021

        In this case it makes the long-term trend disappear. Shifting the 1950-1980 base period values made it possible. Hides the fact that those earlier global temperatures were higher than those being reported now. Pretty slick.

        “One of the scientists, Dr. James E. Hansen of the National Aeronautics and Space Administration’s Institute for Space Studies in Manhattan, said he used the 30-year period 1950-1980, when the average global temperature was 59 degrees Fahrenheit, as a base to determine temperature variations. He said his readings showed that the average global temperature rose about as much since the base period as it did from the 1880’s to the base period – about half a degree in both cases. He stressed that these were estimates and that it would take millions of measurements to reach an accurate global average.”

        “The average temperature was 58.7 degrees Fahrenheit, according to the British data, .07 of a degree higher than the previous record, established in 1990. The British figures, based on land and sea measurements around the world, are one of two sets of long-term data by which surface temperature trends are being tracked. The other, maintained by the NASA Goddard Institute for Space Studies in New York, shows the average 1995 temperature at 59.7 degrees, slightly ahead of 1990 as the warmest year since 1866. But the difference is within the margin of sampling error, and the two years essentially finished neck and neck.”

    Thanks for clarifying, and for the additional commentary.
