In climate it is becoming Less probable to not have a High probability. (by Diego Fdez-Sevilla)

The question: Do you think climate change is caused by man or nature?

I have been here before… and the postures in the debate have started to swing around probabilities. In such a way that it has become Less probable to not have a High probability of “something” as the answer for everything.

I am a deep believer in the value of building questions, sometimes even more than of that for answers, because “questions “shape” the answers”.

So when facing the question: Do you think climate change is caused by man or nature? I prefer to break the question into other related questions:

  • Do you think nature can change the climate?
  • Do you think man can change nature?

So, inevitably there is a key question here:

  • Is climate driven solely by thermodynamic variations or are biological processes involved? For any given answer,
  • Can man alter those factors, either thermodynamic feedbacks (like albedo) or biochemical (like plant’s type and distribution)?

It is like asking if the personality of someone is formed solely based on his character or by its education? Genes or environment?

One example about “questions “shaping” answers”.

Could El Nino season mean help is on the way to resolve the drought in Texas?…

When was the last time that we have seen an article exploring what it represents the “anomaly” in SST in the Pacific so called “El Niño”? It is easy to forget that we are calling names to statistical values because we just do not know what it is that originates them. We only know that they are “somehow” related with probabilistic outputs in atmospheric behaviour, and even at this point, not only El Niño events are followed by the same patterns.

The atmospheric situation triggering flash floods in Texas are the result of a current of warm and wet masses of air moving North from the Mexican Gulf.

Much attention has been dragged in the media into linking these floods to the recent declaration for El Niño conditions.

However, how much different is the actual situation with previous two years? The anomalies in SST in the Pacific for the previous 2013 and 2014 were not an indication of El Niño phenomena.

Furthermore, the patterns of atmospheric events triggering flash floods in Texas at this time of the year is something that has happen in 2013 and 2014 without the declaration of El Niño conditions.  Here some examples from news covering flooding events in the media for the years 2015, 2014 and 2013:

Even with sporadic rain, the situation in Texas facing profound droughts might get complicated due to soil weathering alterations. The structure of the soil changes with persistent droughts, affecting the availability of Nutrients and water retention due to compaction, which limits its movement in depth. The humidity of the soil requires to be distributed in depth in order to help absorbing thermal contrasts due to albedo processes, as well as helping evaporation inducing atmospheric conditions to form rain and evapotranspiration from plants which release compounds affecting cloud seeds via formation of low-volatility vapours. Water moving over the soil surface does not release the pressure over the environment.

The creation of water reservoirs throughout dams and channels release the pressure over the agricultural sector and social demands, however, the anthropogenization of the soil due to droughts and constant manipulation, accelerates its weathering process creating a dependence from constant human support as it becomes domesticated. That means more resources are required to maintain the productivity of the soil.

The white elephant in the room.

When data becomes the centre of attention we are at risk of forgetting its limitations and what this “data” represents.

In environmental science, sometimes we might not understand something but identify that it plays a role or that it is part of a connection between patterns. So in order to make it comprehensible for us and our systems of research, we standardise its behaviour building “anomalies” based on statistics. But since statistics can be too blank and hollow to manage, we apply names to them so they become familiar, and somehow, less empty of meaning. That comes with a risk. The risk of taking familiarity as the answer which makes us forget that we do not really know what those statistical standardised numbers really represent. We make up anomalies, design patterns of behaviour and look for “the probability of an anomaly to occur” (should an anomaly act normally?). So the environment has begun to be described as a conglomeration of probabilistic propositions around “anomalies”. In other words, we call names like the ENSO, NAO, AO, PNA, to numbers which we don´t know how they are originated. In today’s time there is a demand for skills, knowledge and data. But when skills, knowledge and data are not enough what we need is to keep making questions.

Could the NAO be the answer?…

The NOA combines parts of the East-Atlantic and West Atlantic patterns originally identified by Wallace and Gutzler (1981) for the winter season. The NAO consists of a north-south dipole of anomalies, with one center located over Greenland and the other center of opposite sign spanning the central latitudes of the North Atlantic between 35N and 40N. The positive phase of the NAO reflects below-normal heights and pressure across the high latitudes of the North Atlantic and above-normal heights and pressure over the central North Atlantic, the eastern United States and western Europe. The negative phase reflects an opposite pattern of height and pressure anomalies over these regions.

Fluctuations in the strength of these features significantly alters the alignment of the jet stream, especially over the eastern U.S., and ultimately affects temperature and precipitation distributions in this area. Both phases of the NAO are associated with  large-scale modulations of the normal patterns of zonal and meridional heat and moisture transport, which in turn results in changes in temperature and precipitation patterns often extending from eastern North America to western and central Europe.

NAO 2005_2015 by Diego Fdez-SevillaDuring a positive NAO, above average geopotential heights are observed over the eastern U.S., which correlates to above average temperatures. The eastern U.S. often sees a wetter pattern with stronger storms during the winter season in this phase due to increased upper level winds.

During a negative NAO, below average geopotential heights are often observed over the eastern U.S., which correlates to below average temperatures. The eastern U.S. typically receives colder, drier air masses during the winter season in this phase.

2015 NAO Phases composition by Diego Fdez-SevillaThe “standardised” behaviour of the NAO has been observed through major events such as the influence of persistent Negative phase in 2010.

NAO 2010_DJF NOAA by Diego FdezSevilla

Last Winter 2015 (December 2014, January and February 2015) was categorised as a Positive NAO phase. However, the atmospheric patterns associated were a combination of a Positive phase where above average geopotential heights are observed over the eastern U.S., and a Negative phase with below average temperatures.

NAO 2015_DJF NOAA by Diego FdezSevilla

Perspective is everything in environmental science. When we look at the numbers indicating El Nino or the NAO, anomalies over a mean of Sea Surface Temperature or Geopotential Heights, those are images which represent a more complex reality.  When we are looking at data is like looking at the moon. When you look at the moon, do you see the space behind it or only “the moon”?

Investing in knowledge

Cancer has been described as an “anomaly” in the growth of cells. And one similar question has been made as when discussing climatic transformation, Is it caused by man or by nature?

However, in comparison with the debate on the possible anthropogenic impact over climatic events, the approach doing research on cancer has been completely different. Once the anomalies have been identified, they didn´t become answers. Nobody dropped the attention from the main issues, to understand how it works and why it develops. Even considering relevant to use “probabilities” to study the chances of developing cancer (based on analysing interconnections statistically), the main focus of attention keeps pointed on understanding how it is originated, how does it work, what mechanisms are involved, how does it use resources to develop and why.

The conditions in our atmosphere have changed, in composition and structure. And we see it through satellite and on-site observations looking at the number, strength, location and out of seasonality of climatic events. So we have identified “anomalies” to use as tools in order to analyse inter and tele-connections. But they are not describing the mechanisms that originates them.

The lines of research followed in environmental science should be broader and not focus the majority of their resources on finding matching numbers, or increasing the amount of indexes. Those are tools with limitations. E.g In a 24 hours cycle there are some variable which have positive and negative variations from their mean, and they generate very familiar “anomalies”. There are positive and negative anomalies (variations from the 24 hours mean) in the amount of light, in temperature and in biological activity. Identifying the existence of those anomalies was easy, even describing their patterns and cycles. But what it made a difference was to understand that light was “generated from a near star” which “didn´t move around the Earth”. What it made a difference was to understand that the light arriving from the same star,  not only illuminate our planet but also “contains” a form of energy which produce heat. What it made a difference was to understand the processes that explain why, differently from animals, plants could actually “feed” from light and die without it.

An anomaly is not an answer, it is symptom behind answering how and why.

How is changing the configuration of the currents in the Ocean and why?

How is changing the configuration of the atmosphere and why?

What we do know is how and why is changing the configuration of the land surface and the composition of the atmosphere.

My point with this post could be resumed in two ideas:

  • Like with cancer, once the anomalies have been identified in our environment and atmospheric behaviour, the focus of attention should not be placed just upon matching numbers to answer the question of if it is caused by Nature or by man. The main effort should be placed on understanding how and why our environment behaves as it does. Only in such a way we not only will identify “how” can man confront, adapt or  interfere with changes but also, it will enable us to identify thresholds which might force us to change previous assumptions.
  • Nobody claims an inadequacy in the investment of resources following the argument that cancer has not been demonstrated to be caused by man. Therefore, it should not be a matter of debate the relevance of the research effort behind answering those questions trying to increase the understanding of our environment.

Our survival, our welfare,  our health, the cost of our commodities, the resources to accommodate food supplies and medical attention, … our present and our future depends on understanding the limitations of our environment so if we do not invest now then when.

George S. Patto has been quoted saying “If everyone is thinking alike, then somebody isn’t thinking.” May be the difficulty lies for all of us on not following the same patterns of thinking and associated rules. So I admit any line of thinking differing from mine. Otherwise when addressing the challenges of understanding climate it is going to become Less probable to not have a High probability of “something” as the answer to everything.

(This post is part of a more complex piece of independent research. I don´t have founding, political agenda or publishing revenues from visits. Any scientist working in disciplines related with the topics that I treat in my blog knows how to judge the contribution that my work could potentially add to the state of knowledge. Since I am in transition looking for a position in research, if you are one of those scientists, by just acknowledging any value you might see from my contribution, would not only make justice to my effort as independent researcher, but ultimately, it will help me to enhance my chances to find a position with resources to further develop my work.

I believe that the hypothesis that I have presented in previous posts in this blog (here,here and here) could help to understand present and possible future scenarios in atmospheric circulation. However, this is an assessment based on observation which needs to be validated throughout open discussion and data gathering. So please feel free to incorporate your thoughts and comments in a constructive manner.

If you feel like sharing this post I would appreciate to have a reference about the place or platform, by private or public message, in order for me to have the opportunity to join the debate and be aware of the repercussion which might generate d.fdezsevilla(at)gmail.com)
