Four Key Charts for a Climate Change Skeptic

Posted on January 31, 2017 | Leave a comment

Rebloging from WattsUpWithThat “4 Key Charts for the Climate Change Skeptic”.
I could have used these charts to illustrate my reply to a commenter who said that I must not believe in climate change.
From my blog:
Dave
I don’t know any skeptic that does not believe in climate change. Every 100,000 years or so, the Earth experiences roughly 80,000 years of a very cold climate and about 20,000 years of warm climate called the interglacial period. As you can tell the geological scientists mean that the warm period is squeezed in between glacial periods. This cycle has been going on for about a million years. The question is not, does the climate change, but rather what causes it to do so. Surely you don’t think that this natural cycle has been caused by man burning fossil fuels.
Most skeptics believe the primary cause of the change is natural and most think that man’s activities may play a minor role in the recent climate change. What we believe in is actual measurable data. What we don’t believe in is climate models that have proved time and time again to fail to be even close to actual measurements. For eighteen years or so, there was no statistically significant rise in global temperatures. You may think that the recent temperature spike due to a natural event, El Nino, has caused the “pause” to be broken. I ask you to look at the predicted temperatures versus the current temperature and you will still see that it is way below what is predicted by the computer models. And here is a kicker, the atmospheric CO2 levels used in these selected mean computer temperature predictions are typically lower than the actual measured CO2 level. Wow. That should make the spread between actual and computer predicted temperatures even bigger.
No, I don’t want dirty water or air. You propose so many strawmen that you could populate a remake of the Wizard of Oz. I support the Clean Water and Clean Air Acts. Have done so as an engineer and manager of design and installation of environmental facilities throughout my industrial career. But how is it that one could support regulations that are predicated on SECRET SCIENCE? The EPA is out of control. Congress makes the laws. The EPA cannot be allowed to do that.

Ice Cores and Global Climate Part 3–CO2 Follows Temperature

Posted on February 22, 2016 | 2 comments

The previous posting showed that the temperatures in the past have exceeded the current temperature rise giving lie to the assertion that the year 2015 was the hottest year ever.

A cursory examination indicates that the warmers do not dispute the temperature records derived from the ice cores. But looking at the relationship of carbon dioxide (CO2) and temperature rise and fall as indicated by the ice core record, some warmers do not agree with the idea that CO2 follows temperature rise and fall rather than leads. First a look at graphical representations of the ice core data:

vostokwithco26a010536b58035970c0120a62f922e970c

To understand this chart, remember, time flow to the right from the past to the present. When examining the blue, temperature, and the red, CO2, the line to the right is later. For example, look at the blue and the red line beginning about 140,000 years ago. The red line is very close to the blue line but it is to the right of the blue line meaning that it is lagging the rise in temperature shown by the blue line.  The difference is more apparent if you click on the chart to enlarge it.   Note that the thickness of a line on this chart may be the equivalent of 1,000years. The creators of this chart meant to show the CO2 lagging the temperature because that is what their data told them.

Ice Cores and Global Climate Part 2. Are Current Temperatures Highest Ever?

Posted on February 20, 2016 | 5 comments

As discussed in the previous posting, examination of ice cores can provide high quality data about the Earth’s climate from thousands of years in the past.    Antarctica’s ice cores cannot be surpassed for the longest age records. Let us look once again at the Vostok ice core drilling. (Click on all the charts to enlarge.)

Vostok-400Kd

This illustration reverses the direction of time flow from that of the previous posting’s chart. It does expand the data from about 120,000 years ago to the present.

The chart blue line is the ice core temperature data referenced to the global temperature. The flat red line is the average of global annual temperature means for the period 1998 to 2008. This provides a reference with which to compare the past temperatures. And lastly, the green is the annual mean temperature for 2008.   Several things are obvious. First, recent temperatures are not as warm as previous temperatures at their peak. Second, the globe began to exit the last glacial period about 15,000 years ago, and the temperature increased fairly rapidly (of course rapidly on this chart may be several thousand of years). It is not possible to attribute this rise nor really any other rise shown on this chart to something that man has done.   The current period has been relatively stable.

Plate Climatology Theory

Posted on February 5, 2016 | Leave a comment

ClimateChangeDispatch posted “Global Warming and Plate Climatology Theory” on 7 October 2014.   The posting was written by James Edward Kamis, a Geologist who says he believes there is a probable connection between Geology and Climate. He begins this discussion of his theory by saying:

“The Sun, quite obviously, is the first order driver of Earth’s climate, but a much neglected second order driver can contribute significantly to short-term variations. The theory proposed herein is that periods of active Earth tectonism can be correlated to periods of active climate change and climate related events.

Increased global tectonic activity equates to more faulting and crustal plate movement, which leads to more global heat release from faults, fractures and volcanoes that are more active.

Altered heat input equates to climate change.

Are Seafloor Volcanoes Altering The Climate?

Posted on February 4, 2016 | Leave a comment

I have received some interesting email of late that states that seafloor volcanoes are altering the Globe’s climate. So, I have been combing through the internet to see what I could find on this topic.

One theory is that seafloor volcanoes are more active in the time of glaciations than at time of the warming period in between. The thinking is that the increased weight of the ocean’s water, as it rises due to glaciers melting, reduces the activity of the many seafloor volcanoes.   The converse is true about the land-based volcanoes that would become more active as the weight of the glacial ice disappears. The ash emitted from land-based volcanoes can cause cooling of the atmosphere but seafloor ash does not get into the atmosphere.

Climate Change Reconsidered II: Physical Science–An Unbiased Report

Posted on December 30, 2015 | Leave a comment

The International Panel on Climate Change (IPCC) issues a report every three or four years about global warming. This UN agency’s charter is not to examine the science of global warming but rather to show that man produced greenhouse gases will result in catastrophic damage to the globe.   IPCC does as directed by giving little consideration to data, science or reports that would contradict the charter.

A relatively new report, compiled by the Nongovernmental International Panel cover of part2FrontCover2on Climate Change (NIPCC) has been written to answer the IPCC’ reports. The first installment is Climate Change Reconsidered II: Physical Science (CCR-II). This installment is an independent, comprehensive, and authoritative report on the current state of climate science. It is the fourth in a series of scholarly reports produced by the (NIPCC), an international network of climate scientists sponsored by three nonprofit organizations: Center for the Study of Carbon Dioxide and Global Change, Science and Environmental Policy Project (SEPP), and The Heartland Institute. Real data and unbiased studies were used in the preparation of this installment.

“The Most Comprehensive Assault On ‘Global Warming’ Ever”.

Posted on December 29, 2015 | 1 comment

Mike Van Biezen is a physicist and former believer in catastrophic man-made global warming. His epiphany occurred about 7 years ago, he says, when he realized that between 1940 and 1980, global temperatures had actually declined mallorcatempsscreen_shot_2015-12-23_at_9.47.41_ama bit all the while CO2 was accumulating in the atmosphere at a high rate. Since then, his research into the theory of global warming has converted him to skepticism. Van Biezen says there are many scientific problems with the assumption that human activity is causing “global warming” or “climate change”. He has picked 10 of the many scientific problems and listed them in his posting on the Dailywire.com. titled “The Most Comprehensive Assault On ‘Global Warming’ Ever”.

I will use his heading for each of the ten problems and pick out parts of his explanation of the nature of that specific problem. Of course you will get much more out of this if you use the link to his posting and read all of his explanation.

COP21: Dreams From My (Father?) Climate Computer Models

Posted on November 21, 2015 | 1 comment

Data dominates the skeptic’s view of the state of the globe’s temperature and where that temperature may be heading. The climate computer models dominate the warmers view. Temperature is at the heart of the global warming issue in that just about every other indicator is a function of the temperature. For example, sea level change is the product of melting ice at the South Pole and Greenland along with the lesser masses of ice in the high elevations of the mountain ranges. Rainfall, and its shadow drought are said to be forced by changes in the temperature. Higher ocean temperatures, we are assured, breed the hurricanes and typhoons. So this posting will focus on global temperatures.

First it would be well to try to understand the past. Ice core analyses from the Antarctica were used to reconstruct global temperatures for the last 420,000 years. Figure 2 below, from climate4you.com illustrates the temperature for that period of time:

VostokTemp0-420000 BP-2

Fig.2. Reconstructed global temperature over the past 420,000 years based on the Vostok ice core from the Antarctica (Petit et al. 2001). The record spans over four glacial periods and five interglacials, including the present. The horizontal line indicates the modern temperature.

From climate4you.com comes the following discussion: “The present interglacial period (the Holocene) is seen to the right (red square). The preceding four interglacials are seen at about 125,000, 280,000, 325,000 and 415,000 years before now, with the longer glacial periods in between. All four previous interglacials are seen to be warmer (1-3°C) than the present. The typical length of a glacial period is about 100,000 years, while an interglacial period typical lasts for about 10-15,000 years. The present interglacial period has now lasted about 11,600 years.

Skeptic And Warmer Viewpoints On Global Warming

Posted on April 11, 2015 | Leave a comment

arguinginternetimagesRonald Bailey is the science correspondent for Reason.com. On 3 April he posted: “What Would Convince You That Man-Made Global Warming Is Real.” He was, at one time, a skeptic but several years ago, changed is mind and became a believer in the anthropogenic global warming (AGW) theory. His posting has examples of why he changed his mind and wonders if these examples might convince other skeptics to become a warmer.

The posting resulted in a number of responses, some of which I will cover in this posting. The responses essentially are refutations of Bailey’s reasons for his conversion
