Neil deGrasse Tyson Is Wrong. Skeptics Know Science Better Than Warmers.

Posted on February 24, 2016 | 3 comments

I want to respond to Astrophysicist Neil deGrasse Tyson’s video titled “Neil deGrasse Tyson explains the real problem with climate change deniers” so here goes. The problem according to Tyson is that “deniers” do not understand science. “They can not sort out what is true and what is not true,” says Tyson.

If you watch late night TV or mainstream TV news you probably know Tyson. He and Bill Nye “the science guy” are their favorites when the media want someone to talk about “deniers” and global warming. Tyson is reasonably informed about the theory of man-made global warming while Nye is an embarrassment. See Nye’s debate with Marc Morano of Climate Depot.

Back to Tyson.  Climate Depot has assembled a list of 700 or so prominent scientists that are skeptics. Most of them have as much or more understanding of climate science than does Tyson. Is Tyson overwhelmingly arrogant or living in a cocoon? I suspect the answer to that is probably both. With regard to the cocoon, he probably never looks at any of these Skeptics work or their reasons for being skeptical.

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:

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.

Ice Cores And What They Tell Us About Global Climate

Posted on February 18, 2016 | 2 comments

Ice cores provide information about the climate in the past and this allows us to compare it with the current climate to determine how it stacks up. While some of the readers may know a lot about ice cores, this posting provides general knowledge for those of you that are not so familiar with ice cores. The next posting will discuss the results of the information gather at two sites in the Antarctic.

The Vostok location, one of many places where ice cores are drilled, is part of the Antarctic ice cap. At this location the snow falls each year and the temperature doesn’t rise above freezing. In fact this location is called the coldest place on Earth.

This is how the ice sheets are formed. The surface layer of snow contains gaps between the snowflakes containing air. As subsequent season’s experience snow falls, the older snow begins to compress. The compression forms a grainy material (firn) said to resemble the texture of granulated sugar. As the snow above continues to accumulate, the firn eventually densifies and closes off the pores and the air is firmly trapped. The ice sheet now has inclusions which can be analyzed. When the ice is cored out of this ice sheet, large amounts of information can be obtained for analysis. Wiki has this to say about the ice core samples:

“Ice cores contain an abundance of information about climate. Inclusions in the snow of each year remain in the ice, such as wind-blown dust, ash, pollen, bubbles of atmospheric gas and radioactive substances. The variety of climatic proxies is greater than in any other natural recorder of climate, such as tree rings or sediment layers. These include (proxies for) temperature, ocean volume, precipitation, chemistry and gas composition of the lower atmosphere, volcanic eruptions, solar variability, sea-surface productivity, desert extent and forest fires.

4 Major Warmers Change Their Mind And Now Back Building Nukes

Posted on February 15, 2016 | 1 comment

Back when there was temporary shortage of natural gas, that fossil fuel was the favorite of warmers. When it became abundant, they were against it.   They just pretend to be even handed. Well what about nuclear energy? It doesn’t produce carbon dioxide (CO2) but they do not like it. My guess is that many of them are just following through on their objective of destroying capitalism.

However, a group of influential warmers now say they were wrong to oppose nuclear energy.

At the Paris COP21 in December 2015, a press conference was held where 4 noted warmers announced that they were going to back development of nuclear energy.

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.

2015 Was Not The Hottest Year

Posted on February 1, 2016 | Leave a comment

Seems like that every day some warmer announces that 2015 was the hottest year on record. One wants to ask, “what record” are you taking about? Reconstructed temperatures for thousands if not millions of years suggest that there are many periods that have had higher temperatures that those we are experiencing today. For those years which we have reasonably accurate temperature measuring devices they would suggest that 2015 was likely not the hottest although it might be among the hottest.   Of course there is the problem of “man-made” warming as discussed in this posting “ This Is “Man-Made” Global Warming Courtesy Of NASA”.

To give another perspective on this issue, let us use the recent posting by James Delingpole “No, 2015 Was Not The Hottest Year Evah…”. Delingpole has a really sharp wit. He uses it in this posting of his, and if you wish to experience it, click on the posting link above.   I plan on just using his 5 points that he believes clarify the issue and demonstrate that 2015 was not the hottest year. So here goes:

“Here is why they’re all talking rubbish and you needn’t worry about that “Hottest Year Evah” one bit.

  1. The satellite data show no warming

Compare the two trends (below): the upward one comes from the surface temperature dataset used by NASA GISS (and NOAA and the Met Office – they’re all pretty much interchangeable); the flat trend comes from the more accurate satellite data. Which one do you trust?

  1. NASA has fiddled the raw temperature data on an ‘unbelievable scale’

From the publicly available data, Ewert made an unbelievable discovery: Between the years 2010 and 2012 the data measured since 1881 were altered so that they showed a significant warming, especially after 1950. […] A comparison of the data from 2010 with the data of 2012 shows that NASA-GISS had altered its own datasets so that especially after WWII a clear warming appears – although it never existed.

Lomborg Says Wind And Solar Will Still Not Be Competitive By 2040

Posted on February 1, 2016 | Leave a comment

Bjorn Lomborg asks in his posting “Are wind and solar energy already competitive with fossil fuels?” He says no they are not and probably will not be competitive even by 2040.

“We constantly hear how solar and wind energy is already cheaper than fossil fuels. A few months ago, Bloomberg Business ”wind power is now the cheapest electricity to produce in both Germany and the U.K., even without government subsidies.” If renewable energy is cheaper than dirty fossil fuels, why isn’t everyone adopting them? Are we so irrationally addicted to polluting energy sources that we won’t even embrace cheaper and cleaner alternatives?

Well, as you might have guessed, it turns out that wind and solar energy isn’t cheaper than fossil fuels in the real world. A new report by the same Bloomberg now warns that if subsidies are phased out by 2020 in the U.K, the renewable industry will dry up and drop off a cliff. ”

300 Scientists Tell Chairman of the House Science Committee: ‘we want NOAA to adhere to law of the Data Quality Act’

Posted on January 30, 2016 | Leave a comment

This posting is a reblog of Anthony Watts posting on his site “WattsUpWithThat?”
The issue here is that NOAA, undoubtedly to assist the COP21 Paris meeting participants, manipulated their global temperature record to in an attempt to show that the 18+years of no significant warming (“the pause”) had not really occurred.

Now 300 scientists have sent a letter to Representative Lamar Smith saying that NOAA did not follow the Data Quality Act. This, along with Smiths subpoenas of email communications from those people in NOAA who manipulated the temperature record, hopefully with out the perpetrators of this scam.

Warmer Proof For Ocean Acidification Is Invalid

Posted on January 27, 2016 | Leave a comment

In 2004, a paper by Dr Richard Feely and Dr Christopher Sabine was published that purports to show that as the atmospheric CO2 increases, the oceans become acidified (1).   In 2010, Dr Feely made a presentation to the US Congress where he used this graph to illustrate the reduction of seawater pH.   It is reported to be widely used as a reference.

The graph is shown below:

Feelygraph

The question that one researcher asked, when he saw the chart was-Why the pH readings, in Feely’s chart, began in 1988?; which was surprising, as instrumental ocean pH data have been measured for more than 100 years — since the invention of the glass electrode pH (GEPH) meter.

Marrita Noon’s posting “What if Obama’s climate change is based on pHraud?” relates the story of this researcher’s observations:
