Global climate confusion, part two.

More on the many and varied approaches to this complex subject.  Again, a long piece which, dear reader, I hope you will stay with.

As I wrote in response to Per Kurowski’s comment on yesterday’s Part One of this article, ” I am reminded of the saying that in war the first casualty is truth. It ‘feels’a lot like that in this scenario.

Part Two isn’t attempting to indicate the truth, just the many opinions out there.

First, let me quote an email that Patrice sent to me late last night,

Hi Paul!

I think that the propaganda from the fossil fuel and other feudal plutocracies have confused the issue. The primary problem is not “climate change” (aka planetary heating/broiling).I am not confused, because it’s NOT about climate change. Climate change is a second order effect. It may, or may not happen, short term.

The gist of my essay is that climate change will NOT happen, short term, if the sun cools down spectacularly, as it did TWICE in the last five centuries (~ Little Ice Age).

The way to look at things correctly, thus, is CO2 POISONING. Even if the sun cooled down spectacularly, as I emphasized, the ACIDIFICATION of the oceans would proceed unabated. After killing the oceans, if the sun goes back to normal, the greenhouse would rebound enormously.

Although I did not speak of it in that particular essay, we now know the rate of CO2 in the atmosphere, through shell formation in the ocean, for at least 20 million years (and soon at least 100 million; the method should work for half a billion years!). Thus we know the level of CO2 equivalent is the highest in 20 million years (although some have claimed that transitory fluxes much higher than that have occured, from volcanoes; that would not be a problem, as a high flux does not allow storage in the oceans!)

Feel free to quote from this, I just thought of this formulation now, and it may help clarify matters (and it is clearly the idea of the essay).  BTW, let me emphasize that my essay explains why FLOODING, by no means certain on a proxymal massive scale, is, however a clear possibility. London under water seems even a near certainty on the scale of a century (but for enormous works, requiring huge energy!)

Patrice

OK, a useful footnote to yesterday’s piece.  But then if one goes back to Patrice’s original article on his Blog on 31st May, 2009 and reads the comments, you find this, (and I’m going to quote entirely from Mr Day’s comments).

Barry Day says

(QUOTE)What does this mean? We should be cooling down, because the sun’s output has been going down as much as an astounding 6% in some frequencies. But, nevertheless, the lower troposphere has been warming up (END QUOTE)

Ever heard of lag?

“New data show that the balance between the airborne and the absorbed fraction of carbon dioxide has stayed approximately constant since 1850, despite emissions of carbon dioxide having risen from about 2 billion tons a year in 1850 to 35 billion tons a year now.”

“This suggests that terrestrial ecosystems and the oceans have a much greater capacity to absorb CO2 than had been previously expected.”  From Pysorg.com of November 10th, 2009.

Then Barry Day looks at earthquakes,

From EARTHQUAKES – WHAT ARE THE LONG TERM TRENDS?

“Apart from the “long-term” trends shown above, which show an ongoing persistent increase, it is perhaps more stark to record that earthquakes across the planet show a marked increase in activity since 1997. There are more major earthquakes occurring now, and this on an ever more frequent basis.”

From Worldwide Earthquakes [Magnitude 6 to 9.9] have increased by 47 percent in under 3 decades

“A total of  1,085 earthquakes measuring magnitude 6 or greater occurred between 1980 to 1989, averaging 109 per year over the decade. In the 1990s the decadal total increased to 1,492 averaging at 149 major earthquake  per year over the period.

Since January 1, 2000 [ see table below for the date and time] a total of 1,438 major earthquakes have so far occurred worldwide raising the annual total over the last 9 years to 160 with more than 12 and a half months to go to the decade’s end.

The increase from 109 to 160 major earthquakes per year in the 1980 to 2008 period translates to a rise  of 47 percent in just under three decades.” [This reference is dated December 13th, 2008, before the Japanese earthquake, Ed.]

The Barry Day goes on to highlight these references,

From MISTAKES IN IPCC GLOBAL WARMING CALCULATIONS

Abstract
The United Nations Intergovernmental Panel on Climate Change (IPCC) released its Fourth Assessment Report (AR4) in 2007. Here we show that the accurate value for climate sensitivity is 0.277 K/(W/m^2), which is 3 times smaller than the generally accepted value of 0.8 K/(W/m^2). Thus the climate change on doubling CO2 from 300 ppm to 600 ppm will be 1.0 degree, not 3 degrees. Because the IPCC data show that doubling CO2 will not double absorption of infrared radiation, the Beer-Lambert law is not being followed, because of diminishing returns after more-than-50% absorption.

[This is an extremely difficult essay for a non-scientist to follow.  All I can do is to include the source of the article, as below, Ed.]

This article by Roger Taguchi, 234 Knox Crescent, Ottawa, Ontario, Canada K1G 0K8, e-mail address rtaguchi@sympatico.ca, was posted on Monday Aug. 31, 2009.

Then Barry adds another comment,

We’ve forgotten that this isn’t the first time our seas have warmed. Sea temperatures also shot upward 10º to 18ºF just prior to the last ice age.

As the oceans warmed, evaporation increased. The excess moisture then fell to the ground as giant blizzards, giant storms and floods (Noah’s Deluge type floods), and a new ice age began.

The same thing is happening today.

It’s not global warming, it’s ocean warming, and humans have nothing to do with it. Our seas are being heated, I believe, by underwater volcanism. Here’s why:

We are living in a period of vastly increased volcanism, said Dixy Lee Ray in her 1993 book Environmental Overkill, the greatest in 500 years. Eighty percent of all volcanism (say experts at NOAA) occurs underwater. Therefore, underwater volcanism should also be the greatest in 500 years.

Our seas, heated by underwater volcanism, are leading us directly into the next ice age . . . and we don’t even know it.
That’s what El Niño is all about. Warmer seas send excess moisture into the sky, leading to increased precipitation.
Worldwide flood activity is the worst since before Christopher Columbus. In Poland, it’s the worst in several thousand years. In the U.S., precipitation has increased 20 percent just since 1970. This is no coincidence.

When that precipitation begins falling in the winter, you have the makings of an ice age.

Here are some further references,

From the Nature website of 29th March, 2001,

South America’s oldest trees give up the ghost of climate past.

They’ve been dead for over 50,000 years, but South America’s longest-living trees still have a few tales to tell. A new study of the growth rings of partially fossilized trees in southern Chile hints that the global climate before the last ice age was rather like today’s.

Barry mentions Kavachi Island and I did a quick search and came up with this.

From Wikipedia,

Kavachi is one of the most active submarine volcanoes in the south-west Pacific Ocean. Located south of Vangunu Island in the Solomon Islands, it is named after a sea god of the New Georgia Group islanders, and is also referred to locally as Rejo te Kavachi (“Kavachi’s oven’). The volcano has become emergent and then been eroded back into the sea at least eight times since its first recorded eruption in 1939.

In May 2000, an international research team aboard the CSIRO research vessel FRANKLIN fixed the position of the volcano at 8° 59.65’S, 157° 58.23’E. At that time the vent of the volcano was below sea level, however frequent eruptions were ejecting molten lava up to 70m above sea level, and sulfurous steam plumes up to 500m. The team mapped a roughly conical feature rising from 1,100 m water depth, with the volcano having a basal diameter of about 8 km.

When the volcano erupted in 2003, a 15-meter-high island formed above the surface, but it disappeared soon after. Additional eruptive activity was observed and reported in March 2004 and April 2007.

Barry then looks as CO2 levels, he writes,

Carbon dioxide
If today’s rising carbon dioxide are caused by humans, what caused the dramatic rise in CO2 levels at the dinosaur extinction?

It was a matter of a moment’s search to find this, from Ice Age Now, Home Page here

If today’s rising carbon dioxide are caused by humans, then what caused the dramatic rise in CO2 levels at the dinosaur extinction? 

Research shows that there was “a sudden and dramatic rise” in carbon dioxide in the Earth’s atmosphere at the dinosaur extinction of 65 million years ago. A recent report attributes the rise in CO2 levels to an asteroid impact.
See http://news.bbc.co.uk/1/hi/sci/tech/2038599.stm

I disagree. I think today’s rise in CO2 levels can be attributed to our warming oceans. After all, the oceans are known as a carbon dioxide “sink,” especially when the water is cold. 

But as the water warms up, it releases CO2 into the atmosphere. This happens in much the same way that a warm bottle of home-brewed root beer will release CO2. And if you give that CO2 no way to escape, the bottle will explode.

We’ve got it backwards. We’ve got cause and effect in reverse.

The CO2 is not causing global warming. Instead, our warming oceans are releasing CO2 into the atmosphere.

It’s not global warming, it’s ocean warming, and it’s leading us into an ice age.

Finally, Barry offers this,

No Global Warming
“Even with needed corrections, data still don’t show the expected signature of global warming,” says Dr. Roy Spencer, Senior Scientist for Climate Studies NASA/Marshall Space Flight Center.

Unfortunately, the URL that Barry included didn’t function.  But a quick search on the NASA website came up with this,

Contrary Thermometers

Scientists are working to understand why the lower atmosphere isn’t heating up as fast as some global warming models predict.

July 21, 2000 — The question sounds like a Zen koan: How could the globe be warming and not warming at the same time?

That’s the riddle posed to climatologists by satellite and radiosonde data which show that while the Earth’s surface has been warming over the past decades, the lowest layer of the atmosphere shows a weaker warming trend.

The measurements are surprising, because computer simulations of the world’s climate predict that the two lowest layers of the atmosphere — which together form the “troposphere” — should be warming faster than the Earth’s surface.

Read the full article here.  It’s well worth reading and concludes with these closing paragraphs,

Current models suffer from several shortcomings.

For example, clouds are not well represented by the models. The resolution of current models is too coarse for features as small as clouds, Spencer said. Yet clouds clearly play a crucial role in climate due to their influence on humidity, precipitation and albedo (the percentage of solar energy reflected back into space as light).

“The role of clouds is still regarded as one of the biggest uncertainties in global warming predictions,” Spencer said.

The ability of plants to remove carbon dioxide from the atmosphere and the role of soils have only recently been added to the models, and scientists aren’t confident yet of how the models portray these factors, Spencer said.

“While we know that vegetation takes up some of the carbon dioxide we generate from burning of fossil fuels, how that sink of carbon will change in the future is still pretty uncertain,” Spencer said.

Climate models are also limited by the computing power available.

“The global models would be much better if computers were much faster,” Spencer said. “Instead, a lot of approximations are made to make the models simple enough to do climate simulations over the whole globe.

“Unfortunately,” Spencer continued, “we know that many of the processes that are crudely represented are quite non-linear, and so have the potential to respond in unexpected ways.”

The Global Hydrology and Climate Center is a joint venture between government and academia to study the global water cycle and its effect on Earth’s climate. Jointly funded by NASA and its academic partners, and jointly operated by NASA’s Marshall Space Flight Center in Huntsville, Ala., and the University of Alabama in Huntsville, the Center conducts research in a number of critical areas.

OK, that’s enough from me for today.  Clearly it would take a great time for a layman, such as yours truly, to go through all this material, and more, to determine the truth of it all, to the very best abilities of science.  For the verdict on whether man’s increased generation of CO2 in the atmosphere is having a global effect on the global climate should be in the hands of scientists.

Once science has shown cause and effect then, and only then, should politicians endeavour to offer the way forward for society.

Having said that, there is no reason at all for mankind to maintain the present disconnect from Planet Earth.  Even if the jury is still well and truly out in terms of the effect of CO2 on the atmosphere, the number of other issues that are just as important for our long-term survival are still prodigious.  There’s an old saying in aviation, “If there’s any doubt, there’s no doubt.”

One thought on “Global climate confusion, part two.

  1. Dear Paul:
    Nearly all serious scientists connected to the field know that CO2 poisoning is an unfolding catastrophe. And your precaution principle from aviation sums it up, if need be.
    Some scientists (especially 2 famous directors of the Institu de Geophysique in France, Allegre and Courtillot) have strongly, and famously disagreed, but they are on the take from the fossil industry, or just selling books… Similarly from the Koch brothers in the USA
