Global Warming Alarmists, The Earth Is Cooling

Climate change itself is already in the process of definitively rebutting climate alarmists who think human use of fossil fuels is causing ultimately catastrophic global warming.  That is because natural climate cycles have already turned from warming to cooling, global temperatures have already been declining for more than 10 years, and global temperatures will continue to decline for another two decades or more.
That is one of the most interesting conclusions to come out of the seventh International Climate Change Conference sponsored by the Heartland Institute, held last week in Chicago.  I attended, and served as one of the speakers, talking about The Economic Implications of High Cost Energy.
The conference featured serious natural science, contrary to the self-interested political science you hear from government financed global warming alarmists seeking to justify widely expanded regulatory and taxation powers for government bodies, or government body wannabees, such as the United Nations.  See for yourself, as the conference speeches are online.
What you will see are calm, dispassionate presentations by serious, pedigreed scientists discussing and explaining reams of data.  In sharp contrast to these climate realists, the climate alarmists have long admitted that they cannot defend their theory that humans are causing catastrophic global warming in public debate.  With the conference presentations online, let’s see if the alarmists really do have any response. The Heartland Institute has effectively become the international headquarters of the climate realists, an analog to the UN’s Intergovernmental Panel on Climate Change (IPCC).  It has achieved that status through these international climate conferences, and the publication of its Climate Change Reconsidered volumes, produced in conjunction with the Nongovernmental International Panel on Climate Change (NIPCC).
Those Climate Change Reconsidered volumes are an equivalently thorough scientific rebuttal to the irregular Assessment Reports of the UN’s IPCC.  You can ask any advocate of human caused catastrophic global warming what their response is to Climate Change Reconsidered.  If they have none, they are not qualified to discuss the issue intelligently.


Check out the 20th century temperature record, and you will find that its up and down pattern does not follow the industrial revolution’s upward march of atmospheric carbon dioxide (CO2), which is the supposed central culprit for man caused global warming (and has been much, much higher in the past).  It follows instead the up and down pattern of naturally caused climate cycles.
For example, temperatures dropped steadily from the late 1940s to the late 1970s.  The popular press was even talking about a coming ice age.  Ice ages have cyclically occurred roughly every 10,000 years, with a new one actually due around now.
In the late 1970s, the natural cycles turned warm and temperatures rose until the late 1990s, a trend that political and economic interests have tried to milk mercilessly to their advantage.  The incorruptible satellite measured global atmospheric temperatures show less warming during this period than the heavily manipulated land surface temperatures.
Central to these natural cycles is the Pacific Decadal Oscillation (PDO).  Every 25 to 30 years the oceans undergo a natural cycle where the colder water below churns to replace the warmer water at the surface, and that affects global temperatures by the fractions of a degree we have seen.  The PDO was cold from the late 1940s to the late 1970s, and it was warm from the late 1970s to the late 1990s, similar to the Atlantic Multidecadal Oscillation (AMO).
In 2000, the UN’s IPCC predicted that global temperatures would rise by 1 degree Celsius by 2010.  Was that based on climate science, or political science to scare the public into accepting costly anti-industrial regulations and taxes?
Don Easterbrook, Professor Emeritus of Geology at Western Washington University, knew the answer.  He publicly predicted in 2000 that global temperatures would decline by 2010.  He made that prediction because he knew the PDO had turned cold in 1999, something the political scientists at the UN’s IPCC did not know or did not think significant.
