The Search for Acceleration, part 10, US Gulf Coast

February 17, 2014

magnifying glass 145This is part 9 of a series of posts in which I am searching for a large acceleration in sea level rise rate in the latter part of the 20th century.  Such a rise rate is needed  to reconcile the 1.8 mm per year average rise rate for the century attributed to tide gauge data and the approximately 3 mm per year rise rate for the tail end of the century attributed to the satellite data.

U.S. Gulf Coast

This region  has 4 tide gauge sites with at least 90% data completion between 1950 and 2008.  Three of the sites have data back to 1930 or earlier .  I will analyse this data in my usual manner: detrending, weighting, averaging and derivatives.

This slideshow shows my standard analysis.

Conclusion

One thing is certain from the above graphs: the sea level rise rate in the US Gulf Coast region has not shown an acceleration in the last part of the 20th century or the 21st century. The rise rate reached a peak in the 1940s and has been dropping since around 1970.

Keep in mind that there are many factors that contribute to the rise rate in this region.  Subsidence is the primary cause, and subsidence itself has multiple components.

Vermeer and Rahmstorf paper rejected

January 31, 2014

Vermeer and Rahmstorf had a paper rejected by the journal “Climate of the Past.” This news is 16 months old, but I just heard about it, and could find very few references about it on the web.

This paper, On the differences between two semi-empirical sea level models for the last two millennia,  promoted their earlier sea level rise models.  They couldn’t seem to get traction with this paper.

Here are some reviewers’ comments…

One of the major problems with this work is the decidedly biased analysis and presentation.

Highly biased analysis and presentation.

It currently takes significant effort to figure out which pairs of models and training data sets the authors use, and whether they have evaluated all the relevant combinations of the same.

No surprise here.  Rahmstorf has a history of alluding to all kinds of data sets and implying that he has taken them into consideration, but only presenting results for those that support his thesis.

And the final blow…

In the light of the two negative reviews and one comment which all require new analyses and point to fundamental flaws in the methodology of the current paper, I regret to inform you that my conclusion is to support rejection. I strongly dissuade the authors from submitting responses and a revised version.

Here is the paper…

Here is the reviewers’ discussion that lead to the the rejection.

Of course, Vermeer and Rahmstorf do not give up that easily, and similar papers have been shopped around to other journals

Why left-leaning environmentalists ignore southern peril

January 23, 2014

I have pointed out the imminent danger of global freezing to the Southern Hemisphere.  I have pondered why it is that the left-leaning environmentalist get all worked up about warming in the arctic, but don’t seem to be bothered by rapidly advancing ice in the South.  I am not sure if their prejudices are conscious or subconscious.

I promised that the answer to this question would break the story wide open.  Here it is…

Akademik Shokalskiy: Reality is stranger than satire

December 31, 2013

A few days ago I wrote

Our prayers go out to the scientists and others on this harrowing adventure as ice breakers race to free them the frozen grip of the sea.  I hope the sauna stays warm and the booze holds out until they get there.

Today the Sydney Morning Herald writes

The ship is stocked with two weeks’ worth of fresh food and another fortnight of dehydrated rations. But [ship’s doctor Andrew] Peacock said drinks were running low, with “just enough alcohol left to celebrate” the arrival of 2014.

“We are preparing for evacuation to a dry ship so a few drinks seems reasonable, but we also have to be ready at a moment’s notice for the helicopter arrival so staying sober is important.

A “dry” ship?  Oh my, that will ruin all the fun!

The Morning Herald goes on to lament that…

…passengers had been upset by speculation on social media that they were not on a “serious science-based” expedition.

Truth is stranger than satire.

The Guardian removes my simple comment

December 29, 2013

The Guardian has an article about the cruise ship trapped in the Southern Hemisphere sea ice.  I had already written a little satirical blog post with a part the referred to this situation.  So, in the comments section of the Guardian article I said something like…

This is just the beginning of the impending Southern Hemisphere disaster. See… 

http://climatesanity.wordpress.com/2013/12/26/time-to-recognize-approaching-southern-hemisphere-disaster/

I’m not sure if it was the thought police or the satire police at the Guardian who replaced my comment with this…

This comment was removed by a moderator because it didn’t abide by our community standards. Replies may also be deleted. For more detail see our FAQs.

The same comment didn’t seem to bother anybody at Time or CBS.

Its their newspaper and web page and they can do whatever they want, but I wonder which of the Guardian’s “community standards” I violated?  Perhaps you can help me out.  Please vote for the Guardian community standard(s) that you think I violated.

Time to recognize approaching Southern Hemisphere disaster

December 26, 2013

I warned the world before, and they ignored me, but the evidence continues to mount. The Southern Hemisphere, and maybe the entire world, is headed for a frozen doom.

All day long polar orbiting satellites fly over the Antarctic and the surrounding ocean and measure the extent of the sea ice.  The amount of ice waxes and wanes with the seasons, ranging from about 2 to 16 million square kilometers between southern summer and winter.

Thirty years of this satellite data have made it possible to calculate the average ice extent for any given day of the year.  The deviation from this average is called the “anomaly.”  It is this anomaly data that reveals the impending drastic changes in the Southern Hemisphere.

Here is the anomaly data for the last three years from the University of Illinois’ Polar Research Group…

advance rate

The anomaly is increasing by half a million extra square kilometers every year!!! To put this in perspective, the Earth has a surface area of about 500 million square kilometers. Roughly speaking, an additional 1/1000th of the Earth’s surface is covered by ice each year. Consider that the Southern Hemisphere sea ice maxes out at about 16 million square kilometers each year, then 32 years of the current increase rate would double this amount.

By 2050, a mere 36 years from now, the ice encased Tierra Del Fuego on the southern tip of South America will replace Greenland as the most ironically named place on Earth.  By 2100 the dairy farms surrounding the town of Gore in the Southern Plains of the South Island of New Zealand will be a frozen mockery to the same-named purveyor of global warming alarmism.

Here is what is in store for the Southern Hemisphere…

You can’t deny this.  This is science!  My conclusion is based on the proven analysis techniques of NASA climate scientist Jay Zwally.

Has the 21st century brought us to a tipping point?

All the best data indicates that a tipping point has already occurred.  Think about this: according to NOAA data (see here and here) 8 out of 10 years with greatest Southern Hemisphere sea ice extent have occurred since 2000!  Here they are in order…

  1. 9/14/13
  2. 9/24/12
  3. 9/24/06
  4. 9/24/09
  5. 9/29/05
  6. 9/28/00
  7. 9/8/04
  8. 9/29/07

We also now know that the all time low temperature for the Antarctic was reached in 2010.  Satellite data shows that on August 10th, 2010, the Antarctic temperature descended to 136 ºF (minus 93 ºC).  This shattered the previous record of minus 128.6 ºF (minus 89.2 ºC), set in 1983.

That is a drop in the minimum recorded temperature of 7.4 ºF in a mere 27 years.  If that continues, as indicated by Jay Zwally type analysis, then the low temperature by 2100 could be minus 159 ºF (minus 106 ºC)!!!

The effects are already being felt

It is now the warm season in the Southern Hemisphere.  Sea ice is making its seasonal retreat, yet the Russian cruise ship, Akademik Shokalskiy, is trapped in the sea ice with “52 tourists, scientists and explorers” and a crew of 22.  You would think the combined brains of all those scientists on board would have kept them out of the zone of freezing water.  While the ship’s brochure points out that “Views are excellent from the large, open decks and the Navigation Bridge'” maybe they couldn’t see the ice coming from the vantage point of the “Lounge and bar, open late afternoon and evening with a wide selection of wines and spirits” (an essential feature of all scientific research vessels).  Our prayers go out to the scientists and others on this harrowing adventure as ice breakers race to free them the frozen grip of the sea.  I hope the sauna stays warm and the booze holds out until they get there.

Why the great silence?

Where are the voices of leading scientists and environmentalists?  Why haven’t you seen anything about this impeding hemispheric disaster on the front pages of the news papers or on prime-time news reports?  A subsequent post will soon answer those questions and break this issue wide open.  

Stay tuned…

Not much of Chinese energy is from wind or solar.

December 2, 2013

A few days ago I wrote about the pollyannish belief that “China is slowing its carbon emissions.”  An essential element of this ridiculous meme is that the Chinese are producing significant portions of their energy via wind and solar. Not true.

Consider just electricity.   Here is a breakdown of China’s installed electricity capacity by fuel type in 2011 and their electricity generation by fuel type for 2000 to 2010 from the The United Stages’ Energy Information Administration’s evaluation of China’s energy consumption (2012)…

"China's installed electricity capacity by fuel, 2011," from the US Energy Information Administration's evaluation of China's energy consumption

“China’s installed electricity capacity by fuel, 2011,” from the US Energy Information Administration’s evaluation of China’s energy consumption

"China's electricity generation by fuel type, 2000-2010" from the US's Energy Information Administration

“China’s electricity generation by fuel type, 2000-2010″ from the US’s Energy Information Administration

What do these charts tell you?

These two charts are drawn from the same data set and appear next to each other in the same document.

As you can see from the top chart, 6.2% of China’s installed electricity capacity is in wind or solar.  That is over 60 gigawatts installed.  Compare that the the US’s 60 gigawatts of installed wind and 10 gigawatts of installed solar.

Alas, the top chart shows installed capacity, not actual production.  There is a little thing called the “capacity factor.”  The capacity factor is the fraction of the time that particular power source can actually produce power at its rated capacity.  For example, a one gigawatt capacity nuclear power plant will have a capacity factor of about 90%, meaning it can produce one gigawatt 90% of the time.  Wind and solar capacity factors tend to be much lower, simply because sometimes the wind doesn’t blow and the sun doesn’t shine.  The capacity factor for wind in China is 22%

The second chart shows the amount of electrical energy actually produced using the various “fuel types”.  Do you see that very, very thin yellow band along the top of the second chart?  That represents the Chinese electricity generation due to that 6.2% of installed wind and solar.  Can’t see the yellow line?  Let me blow up the last year of the chart for you…

Chinas electricity generation by fuel type blown up 3

That 6.2% of installed capacity in the form of wind and solar yields less than 1.5% of the actual energy.

China’s energy future

The Energy Information Administration document tells us…

China is the world’s second largest power generator behind the US, and net power generation was 3,965 Terawatt-hours (TWh) in 2010, up 15 percent from 2009. Nearly 80 percent of generation is from fossil fuel-fired sources, primarily coal. Both electricity generation and consumption have increased by over 50 percent since 2005, and EIA predicts total net generation will increase to 9,583 TWh by 2035, over 3 times the amount in 2010.

Wow!  three times as much as 2010, a mere 21 years from now!  Where will all this energy come from?

Again, the Energy Information Administration…

Total fossil fuels, primarily coal, currently make up nearly 79 percent of power generation and 71 percent of installed capacity. Coal and natural gas are expected to remain the dominant fuel in the power sector in the coming years. Oil-fired generation is expected to remain relatively flat in the next two decades. In 2010, China generated about 3,130 TWh from fossil fuel sources, up 11 percent annually.

Let me be clear, I am not knocking the use of wind and solar.  I have been personally working on solar energy for 17 years.  But I am knocking unrealistic expectations and quasi-religious environmentalist beliefs.  And I am not criticizing the Chinese for their increasing energy consumption.  They understand, correctly, that abundant energy is the key to prosperity.
