Guest post by Bob Tisdale
Many bloggers are very active in the climate change debate around the globe. In advance of an expected intensification of that debate this year, I’ve written a new essay about the natural warming of the global oceans. It’s titled “The Manmade Global Warming Challenge”. That essay and an introduction are published in .pdf format so that interested persons can download them and refer to them at their leisure. I hope many bloggers will find them useful in their debates.
For those new to this discussion, the essay includes my easiest-to-understand descriptions of how strong El Niño events are responsible for the vast majority of the warming of sea surface temperatures over the past 3 decades. It’s provided after a moderately complex description that includes links to animations. The intent of the simple description is to reinforce the more-detailed explanation. That is, to show and tell what I’ve just shown and told. The essay also includes discussions of the natural warming of ocean heat content, including a couple of the cartoon-like illustrations from my ebook Who Turned on the Heat?
THE GLOBAL WARMING/CLIMATE CHANGE DEBATE WILL LIKELY ESCALATE IN 2013
The global warming debate should intensify in 2013. In his inaugural address, President Obama promised the people of the United States:
We will respond to the threat of climate change, knowing that the failure to do so would betray our children and future generations.
The draft of the upcoming U.S National Climate Assessment Report was recently released for comment by the U.S. National Climate Assessment and Development Advisory Committee (NCADAC). Its Executive Summary portrays manmade global warming/climate change like most political documents of its kind; that is, it characterizes the climate model-dependent hypothesis of manmade global warming as being based in sound science and it portrays recent weather events as products of greenhouse gas-driven climate change.
Further, NCADAC is supported by NOAA, who recently published their State of the Climate report for 2012. NOAA, unfortunately, has difficulty determining something as simple as what years are La Niña years by their own definition. I suspect NOAA will correct their mistake sometime in the future, but with less fanfare than they provided for the erroneous headline that “2012 was also warmest ‘La Niña year’ on record”.
Later this year, politicians from around the globe will negotiate the language of the Summary for Policymakers of the 5th Assessment Report (AR5) from the Intergovernmental Panel on Climate Change (IPCC) and they will unleash it upon the world shortly thereafter.
As a result, mainstream media coverage of global warming and climate change—or whatever new catch-phrase they choose to use—should reach fevered levels in 2013. I plan to be more active in the discussions this year, spending time at magazine, newspaper and TV news blogs around the globe in an effort to reach a wider group of people.
THE MANMADE GLOBAL WARMING CHALLENGE
To aid in those endeavors, I’ve published an illustrated essay titled “The Manmade Global Warming Challenge”. If you’re a frequent visitor here at Climate Observations and at WattsUpWithThat, you’ve already heard my message: ocean heat content data since 1955 and satellite-era sea surface temperature data indicate the oceans have warmed naturally. I’ve also produced a much smaller teaser—“Introduction to the Manmade Global Warming Challenge”—which will hopefully grab readers’ attentions and prompt them into downloading the full presentation. The introduction and the essay were created in PowerPoint, then converted to pdf. The text should be easy to read, and I’ve formatted the graphs with the thicker curves than I normally use. The “Manmade Global Warming Challenge” is a large document, 42MB, due mostly to the black background. (With a white background the document in pdf form is only 4MB.) There are 180+ slides, with lots of information and illustrations, and it reads very quickly.
The full essay titled “The Manmade Global Warming Challenge” is here (42MB).
The shorter introduction is here (4MB).
Please feel free to provide links to “The Manmade Global Warming Challenge” in your discussions around the blogosphere.
INTERESTED IN LEARNING MORE ABOUT THE NATURAL WARMING OF THE GLOBAL OCEANS?
I’ve searched sea surface temperature records and ocean heat content data for more than 4 years (more than 3 years for the ocean heat content data), and I can find no evidence of an anthropogenic global warming signal. That is, the data indicate the warming of the global oceans was caused by Mother Nature, not anthropogenic greenhouse gases.
I’ve recently published my e-book (pdf) about the phenomena called El Niño and La Niña. It’s titled Who Turned on the Heat? with the subtitle The Unsuspected Global Warming Culprit, El Niño Southern Oscillation. It is intended for persons (with or without technical backgrounds) interested in learning about El Niño and La Niña events and in understanding the natural causes of the warming of our global oceans for the past 31 years. Because land surface air temperatures simply mimic and exaggerate the natural warming of the global oceans over annual and multidecadal time periods, the vast majority of the warming taking place on land is natural as well. The book is the product of years of research of the ocean heat content data and satellite-era sea surface temperature data that’s available to the public via the internet. It presents how the data accounts for its warming—and there are no indications the warming was caused by manmade greenhouse gases. None at all.
Who Turned on the Heat? was introduced in the blog post Everything You Every Wanted to Know about El Niño and La Niña… …Well Just about Everything. The Updated Free Preview includes the Table of Contents; the Introduction; the beginning of Section 1, with the cartoon-like illustrations; the discussion About the Cover; and the Closing.

Note: Bob humorously advised in an email that this is the first essay he has written that didn’t have an illustration, I couldn’t accept that, so I included the one illustration that has never appeared on WUWT (though often suggested) as an appropriate foil. – Anthony
