Planting trees is relevant. Keeping already established trees should be part of environmental policies.

Mature trees and forests have already generated a system of resilience in combination with soil and biosymbiotic net flows. New trees will have to develop symbiotic links in order to perdure over time. And the time a tree or forest perdure is what makes the difference when we evaluate the net equation between Carbon emitted and Carbon sequestrated throughout time.

Mature Natural Carbon sinks reached a point where there was a balance between the conc of Carbon naturally emitted (the earth is warm thanks to that) as the Carbon taken. Now we face a dysfunctional natural system acting as carbon sinks, weaken in resilience which in many places has been completely erased or at its infancy without time to fully develop and “sink” into it.

Biodiversity is being domesticated as much as the biological cycles, and the natural environments polluted. All together have an influence over the right performance of natural ecosystems as carbon sinks.

The challenge ahead will take for more than planting trees, any tree, any where. The challenge is to see them grow, in their eco-habitats as the time passes by.

The issue is that by planting any tree any where, sometimes we damage ecosystems, or even we might spend more energy than need it in order to follow our fashion choice.

I hope you don´t mind if I point you to a post which I wrote about my argument. It is the best way to give you an extended idea and you can give your opinion:

Thermodynamic Ecosystems

Through the whole line of research presented here there is one single idea which links all the assessments.

Being a Biologist myself, I have studied our planet as a global ecosystem which comes from the combination of all the organisms and the abiotic elements which affect them.

An ecosystem is an open system because it can exchange energy or materials with other ecosystems. Earth is a closed system with respect to nutrients and chemicals, but open with respect to energy.

Climate Drift

Based on identifying the role played by all the parts and processes involved in our global ecosystem the concept applied through my research of Climatic Drift is:

The deviation from equilibrium of the conditions allowing the perpetuity of an established symbiotic relationship between biotic and none biotic components in a micro and macro ecosystem. This drift can be due to changes in any component of the ecosystem playing a synergistic effect over the rest. And the causes can be either a change in the magnitude of the already implemented forces in place, changes in the directionality or rates in the flows of energy pre-established OR/AND the impact suffered by the incorporation of new components/forces and energy sinks or sources in any part of the system interfering with the previously established order and balance.

The application of this definition raises many questions addressing the potential impact from human activities over the energy pool in our planetary ecosystem defining climatic regimes as a result of the transformation of:

  • structure and composition of all the phases; liquid as water cycles, Solid as land cover and use and gaseous as the atmospheric compositions, as well as
  • interferences in all the processes involved in the energy flows including industrial and agronomic practises, unbalanced use of resources vs regeneration, changes in physical properties such as albedo, displacement of nutrients, alterations in biogeochemical composition and its distribution worldwide, …

The discussion over the impact from human activities on climatic regimes goes beyond CO2 concentrations and I have discussed my approach in previous posts:

November 17, 2016 Arctic Amplification versus Arctic Absorption (by Diego Fdez-Sevilla, PhD.)   Researchgate:  DOI: 10.13140/RG.2.2.24688.35848

Temperature is measured through an atmosphere with a molecular composition thermically active. The atmosphere is nitrogen, oxygen, and argon. The molecular composition which absorb and retain radiation affecting climatic regimes and ice cover anomalies are GHGs (CO2) being water vapour the major component as part of a feedback with the other GHGs. Through periods of low radiation (winter) temperature drops enough (as in the Arctic should be) so the molecular composition would be mostly N and O without water vapour since it would freeze. So the atmosphere in itself looses its thermal conductance by drying out. How ever, if there is a forced increment of GHGs, like the increase in water vapour measured in the latest decades, the thermal conductance of the air increases, carrying more energy in circulation by water vapour. Being increased the pool of energy carried at the Arctic decreases the amount of energy which the atmosphere can absorb from the oceans. Water releases energy until it freezes only if it the surrounding medium can take all the energy supplied by the ocean. Otherwise it absorbs energy only up to thermal equilibrium. If this equilibrium is higher than freezing there is no ice.

My research points to an increase of the energy pool in the atmosphere carried by water vapour as consequence of transformations induced in the composition and structure of the gaseous, liquid and solid phases of our environment, from increases of CO2 in the gaseous phase, transformations in energy sinks due to land cover management in the solid phase, and alterations over water cycles due to compartmentalization, inland water losses, acidification and pollution. An increase in the energy pool of the atmosphere explains ice loss in the Arctic, ice increase (at the moment) in the Antarctic (differences in land-ocean contrasts with NH), increasing number of events related with strong winds, water downpours and snow fall, heat waves and cold displacements crossing latitudes instead of having smooth transitions through latitudes and longitudes.

Debating Climate, Environment and Planetary evolution. Define your position. (by Diego Fdez-Sevilla)  ResearchGate DOI: 10.13140/RG.2.2.27332.73603 October 2, 2014


The contribution of the development of life over land increased the synergistic connections between Biota, the Earth’s Energy Budget and Climate. The expansion of diverse types of adapted ecosystems around the planet was not random and, the species in each ecosystem were part of a interconnected global system capable of absorbing perturbations derived from oscillations due to rotation, translation, tilt, solar activity, and climatic events. Those oscillations have been always there and the ecosystems developed to absorb them.

The latest in our planetary evolution time line is the incorporation of human development. We arrived in a state of self-sustained ecosystems, with capability to recover, actively (storing energy throughout photosynthesis), from naturally induced thermodynamic passive fluctuations. When we look at the actual state of those ecosystems and the mechanisms of resilience which made our global system stable enough for life to create a state of equilibrium I wonder, are we exploring all the questions? Are we identifying and/or giving the right weight to the right questions?

So, in order to confront such a complex subject as it is to understand planetary evolution under anthropogenic pressure I just want to begin by exploring the state of consensus about which are the questions (few at the time) considered relevant to keep in mind as part of the debate.

Two major components are working side by side in our planet. Passive mechanisms driven by thermodynamic forces transferring energy between components of the ecosystem and, Active processes absorbing, transforming and storing energy throughout biochemical processes. Consequently, two postures rise in the debate from these two mechanisms.

Are thermodynamics defining the state which allow life to evolve in a changing climate? or, Are biotic systems which develop against thermodynamic fluctuations taming the weather?

At this point is where my initial comment comes into place. I am surprised by having the sense of that there is a given protagonism to thermodynamic properties of a single element (CO2) at the expense of lacking attention into how the development of the human specie is transforming the environment with an unknown impact over the forces and mechanisms driving the evolution of the global environment.

From an environmental point of view I understand that any ecosystem has a limited capacity to absorb perturbations. Transforming the environment triggers an impact not only over what the new environment produces, but also, over the capacity for the environment to absorb perturbations (resilience).

DiegoFdezSevilla spring overwhlemedSo, how much “instability” either triggered by changes in Solar radiation, Planetary positioning, Oceanic circulation and Atmospheric composition is being absorbed by our functional global environment?

And, consequently,

how much transformation can absorb our environment before it gets overwhelmed-dysfunctional (overstretch) allowing magnifying factors to stretch the extremes in naturally induced oscillations either triggered by changes in Solar radiation, Planetary positioning, Oceanic circulation and Atmospheric composition?

Through the time line occupied by man, among all the forces interacting with our environment, only those naturally induced behave drawing patterns describing pendulum like oscillations in their magnitude. However, the pressure enforced over the environment by human development is constant and increasing.

In a mathematical representation of all the forces interacting with our environment anthropogenic transformation might be the only constant among all the variables. Accordingly, considering time, and without a natural variable suddenly adopting an overwhelming magnitude, makes this constant force the one setting the direction in the evolution of the whole system. That is because time has a bipolar repercussion in the magnitude of naturally induced variables such as Solar activity, tilt, PDO, (positive in one phase of the oscillation and negative in the other phase, that’s what makes them variables) meanwhile, the transformation of the environment constantly accumulates, always in the same direction over time.

Atmospheric Circulation and Climate Drift. Are we there yet? (by Diego Fdez-Sevilla) July 2, 2015


I have been discussing in previous posts my point of view over the mechanisms driving these contrasts on weather events. However, at risk of overstating my thoughts, I want to add my take on this situation. I believe that these “bubbles” or “drops” of weather is the new way for the transition between seasons, by their number, size, location, resilience to dissipate and proximity in time and space to coalesce. And for as long as the thermal contrast between Polar and subpolar masses of air decreases, warm masses of air will reach higher latitudes more frequently. That is my humble opinion.

From my own perspective, and looking at the state of the climate from data and biotic indicators, an increase in intrusions of warm masses of air into higher latitudes will change Ecotypes and Ecoclines affecting the state of Biotopes. If you are not familiarised with the terminology, look for “The Law of Relative Constancy of Habitat—Ecotypes and Ecoclines”.

These bursts of warm air keep reaching further northern latitudes and earlier in time. I can only relate with what I have said in previous posts and messages about possible scenarios linking increases of CO2 and water vapour with changes in atmospheric circulation. I miss having more feedback on my assessments from other scientists. So far things are unfolding as I thought they would. And I don´t like be right about bad things… If I am wrong on my assessment I would feel released, but if I am right, I would feel guilty if I wouldn´t have shared my thoughts.

Defining the Climate drift

The only way to know if we have arrived to our destination is if we know where we are going. If we don´t know what it is that we are looking for, it is very difficult to identify when we have arrived.

At this time it seems that everybody is “waiting” or/and “looking for” the “ultimate proof” in the form of a “statistically significant value“, which will tell us where and what is the destination for our climate (and us by its impact). Therefore, the question keeps coming, are we there yet? But the answer does not seem to arrive easily.

The mere absence of having an answer points strongly to three possibilities:

  • Lack of enough data. We need more time to gather more data.
  • Inaccurate methodologies. We need more time to enhance those. OR,
  • The answer is the existence of a state of “instability”, which by its own definition, can not be modelled or correlated.

Could it be that the answer lies in the difficulty of finding an answer?

Some scientists have faced this situation before when they looked deep into space and found locations from where it was impossible to receive data. The absence of data was the answer. They called them “Black Holes”.

I believe that we might be facing similar situation with our climate. Something that is unstable is by definition unpredictable, for example, earthquakes. And this is something different  from variability. Our climate and natural systems incorporate variability in their behaviour. But the existence of our environment as we know it, comes with a variability within a range of tolerance thresholds. So what we are facing here is the possibility of seeing tolerance thresholds trespassed at various parts of our ecosystem, triggering a chain reaction all over the enclosed system encapsulated by the atmosphere of our planet.

June 18, 2015 Extreme climatic events, implications for projections of species distributions and ecosystem structure (by Diego Fdez-Sevilla PhD)


The weakening of the Polar Jet Stream can be linked with the changing chemical composition of the atmosphere due to increasing CO2 concentrations. The level of graduality in the transition between seasons can be affected due to the burst of Atmospheric events. If these are strong enough to alter the stability of biological systems they well might also affect the synergistic feedbacks existent between biological productivity and the thermodynamic atmospheric behaviour.

These synergistic feedbacks seem to not be of much part of the research available in the literature. Most studies are addressing the survival of species and mechanisms of adaptation against changes in climate or atmospheric behaviour. And yet, I believe that the stability of an ecosystem, biotic and nonbiotic parts altogether, has to be considered as the result of receiving and absorbing perturbations by all sides, atmosphere, biotope and ecotope. When a region losses the capacity to absorb perturbations and regenerate itself to its previous state, the whole balance between land cover and atmospheric behaviour above it will change. And thus, the climatic parameters defining the region. Only by changing the species of vegetation covering land surfaces the albedo will change, inducing changes in convective circulation as well as the chemistry of the soil and its structure.

From regional to a global change only takes to have enough regional changes to coalescence.

As part of the main body of the article I am trying to highlight how difficult it might seen to classify a “climate change” without knowing what is the “change” we are looking for. Is it a “statistically significant” “change”? for which variables? in which range of time? and location? which margin or threshold is defined and considered as the tipping point marking a “change”?.

However, while we are looking for such extreme event to show up in charts, diagrams and models, followed by significant correlations between them, displacements from previous states of equilibrium, are being observed in different parts of the environment.
Differently from numerical models which rely on conceptualizations incorporated in the design of the algorithms applied, biological niches appear indicating the state of a global interaction between biotic and none-biotic components. A niche refers to the way in which an organism fits into an ecological community or ecosystem. Through the process of natural selection, a niche is the evolutionary result of a species’ morphological, physiological, and behavioural adaptations to its surroundings.

When natural species and niches start to appear where they were not before or by different numbers, it reflects a change in the conditions of the environment where they start to develop.

These populations can migrate following the opportunistic generation of new spaces suitable for their development. Or even, in the same niche, some changes in environmental pressures can change the dominance between species since some may adapt faster than others to the new conditions.

With respect to climatic regimes and niches, variability is part of the dynamic process allowing regeneration and perpetuation of a mature ecosystem in equilibrium. Like the succession of the seasons e.g. summer and winter, helps to control the pressure exerted between populations which perform differently in different conditions. The variability incorporated in these conditions becomes a mechanism of regulation moving around a pivoting point which allows the integrity of the system.

When the climatic conditions linked with the development of a specific niche moves from the pivoting point far enough, the synergistic balance in the use and regeneration of resources and energy flows (biotic and none biotic) gets disrupted and requires modifications in the level of performance for all the components of the system.

Looking for what it might be consider the “rigorous” terminology of climate drift I have found that “Stouffer and Dixon (1998) defined climate drift as an unforced trend away from some initial state, with the trend not being part of normally occurring variability about a constant mean state.”

My point of view is that, if there is no agreement about using “climate change” as a terminology addressing the implications from seeing modifications (composition and behaviour) in so many parts of our environment (land, atmosphere/air and water (liquid, solid and vapour)), at least we might find common ground in identifying and/or studying the migration or “drift” of our climatic niches from previous regimes, either by addressing magnitudes, behaviour and/or location.

Biological seasons (like breeding seasons or pollen seasons) are driven by thermodynamic fluctuations. Similarly occurs in the atmosphere with seasons defined by hurricanes, tornadoes, etc.

After my Master in Environmental Biology in 2001, in 2002 I started to be involved in the study of atmospheric dynamics driving the release and transport of biological particles. In this field called Aerobiology I did my PhD researching how atmospheric conditions affect the aerodynamic behaviour of pollen grains when airborne. And in 2008, I performed research (later published a paper) highlighting modifications in biological pollen seasons (start earlier and ends later) due to climatic alterations triggered from urbanization levels.

I am not a meteorologist but, as an Environmental Biologist whom became involved in Aerobiological studies, since 2002 I have been observing and studying atmospheric dynamics, and more precisely in the last 4 years. And I believe that all type of seasons, including those characterised by weather events, are shifting their behaviour becoming more erratic.

I discuss it also in the post “Aug 2016 Follow-up on previous assessments. Atmospheric Dynamics, Temperature Displacements, Atmospheric Mixing (by Diego Fdez-Sevilla, PhD.)” Posted on August 26, 2016

From my research (published in this blog) I see for the NH this episode of cold displacement into southern latitudes similarly to as heat waves moving into high latitudes.

The similarities are that both are events showing temp displacements in latitude (I have extensively written about it).

Both displacements are driven by kinetic dynamics.

August 6, 2015 Atmospheric Composition and Thermal Conductivity. (by Diego Fdez-Sevilla PhD)

Those kinetic dynamics have been normally associated with orbital seasonality (sun’s radiation intensity).

Worst than a change is a pattern of no change ( by Diego Fdez-Sevilla, PhD)


In periods of enough Solar intensity, heat waves predominate from equator towards the pole.

BBC news Spain Winter 2015 Diego Fdez-Sevilla

Altogether these transitions were part of a latitudinal transition associated with the variations in the position of the polar jet stream.

What I interpret from the current dynamics is that, in one hand, the association of orbital seasonality with kinetic seasonality is changing (or it has already and keeps that way “without a change despite ENSO variations”).

The patterns of cold developments associated with latitudinal extension of polar influence has been transformed in longitudinal displacements of masses of air due to a weak polar jet stream creating “pockets” or “drops” of weather where ever they move (see more posts on this at the category “jet stream and polar vortex”):

Europe Forecast Temp 500 Diego Fdez-Sevilla

Europe 20 Aug 2015 drops-of-weather-sept-2016-diegto-fdez-sevilla-phd

Such circumstance has allowed warmer than normal temp in high latitudes meanwhile lower than normal temp are reached from polar displacements into lower latitudes.


The latest consequence of this change in dynamics comes in the form of changing the level of dominance for the orbital driven temp seasonality influence over the kinetic driven due to the thermal energy contained within the atmosphere.

Closing remarks

Our Planet is made from the combination of all the organisms in a given area and the abiotic elements which affect them.

An ecosystem is an open system because it can exchange energy or materials with other ecosystems.
Earth is a closed system with respect to nutrients and chemicals, but open with respect to energy.

Therefore, there is a synergistic relationship between biogeochemical energy flows and those identified in weather patterns and atmospheric dynamics.

As March 2017, I am looking for new opportunities and new challenges, to join a team. At the same time that I look for job openings to incorporate my resume, I would encourage any one finding interesting any of the skills which I apply throughout my research, as well as communicator, to evaluate my profile as a candidate for your projects. email d.fdezsevilla(at)

After performing research and working in institutions linked with environmental research and management, in 2013 I found myself in a period of transition searching for a new job. However, in such competitive scenario, instead of just moving my cv between desks waiting for my next opportunity to arrive, I used it as an advantageous standing point to start and develop independent research in a blog in which I could open my own line of research completely free of external pressures or interferences. Through the whole project I have published pieces of research applying my own perspective focused on addressing relevant environmental questions.

The work which I present in my blog is just a chapter in my career. At Feb 2017, it has reached an stage in which its framework has been defined and it has been applied in follow-ups delivering the subsequent conclusions.

The level of uncertainty which I have accomplished in my assessments has reached enough accuracy to replicate real time developments to the point of compete with models sustained by corporate and administrative budgets.

The economic support sustaining the three years of research presented in this blog has been private based on my own capacity to generate it. Once the main conclusions of the project have demonstrated their value, it is time for my career to find new ways of growth and/or external sources of financial support.

Therefore, at this time Feb 2017, the generation of assessments over present developments discontinues in the absence of external financial support.

You can look at the whole project (more than 190 posts between Oct 2013 to Feb 2017) published at and also you will find some of those publications in my profile at ResearchGate

I am living in Spain free to relocate geographically worldwide.

Since October 2013 I have been publishing pieces of research studying the behaviour of the Polar Jet Stream and the weather events associated as well as the implications derived into atmospheric dynamics and environmental synergies.

Many of the atmospheric configurations and weather and climate events we see these days are very similar with the progression followed since 2013.

For those unaware of the content offered in this blog I might have to issue a warning: Handle with care. Also with the product obtained from scientific analytical thinking there are traces of personal and professional “passion”, by-products obtained from “original and unpeered grey matter juice” originated from “independent critical thinking”. Also sometimes the packaging might be rough around the edges due to its “unfunded nature”.

4 years ago I joined a discussion which made me realise how much knowledge was settled on the past, built upon past conventions and unable to give answers about present developments in all parts of our environment. From the impact from GMOs, plastics, soils degradation, atmospheric composition, land use and cover, water cycles, … I had addressed scientifically unanswered questions before doing my PhD so I decided to give it a go and to offer my take over those gaps. It has been a pilgrimage to become aware of how much faith and fear is put on scientific publishing above raw understanding and discussion.

I do not know how far this blog will go, however, it represents the assessment of a global process and I expect that past posts will become a description of continuous present for the next years.

Altogether, the body of work which represents the line of research presented in this blog is composed by more than 190 pieces, covering data analyses and conceptual discussions. All those different discussions and assessments presented here build together a single concept. The format applied is the result of making a big effort trying to apply simplistic approaches with the aim to allow a multidisciplinary access. Since the topics treated in my publications have implications for many sectors in the academic and not academic world, with the aim of allowing my research for open review, there is also the objective of allowing access to a multisectorial and multidisciplinary audience sharing interest.

My agenda is simple, I am in transition looking for either funding to grow the research published in this blog or for a job position in any field in which my assets are valued. Behind my research there is nothing more, nothing else than to showcase my capabilities doing what I like, research. I am a methodologist. I don´t look at the color of the result obtained, only at the suitability of the method and the coherence of the result. As I have said before, if I am wrong on my assessments and conclusions, it will be better for all, and my work would showcase my capabilities anyway. A CV shines the goals obtained by anyone, but by publishing here my research, I expose myself and my work to public judgement. There is a difference between being naive and raw. If you see the difference you will understand better my work and my personal position.

The aim of publishing my work openly is to allow for it to be exposed for an open review. So any constructive feedback is welcome. After a period of time of at least a month from the publishing date on this blog and at LinkedIn, if no comments are found refuting the value of the piece published I then publish it at ResearchGate generating a DOI for posterior references.

In order to protect my intellectual rights, more assessment in depth and the statistical and numerical analyses that I have performed to support my arguments can be discussed at my email: d.fdezsevilla(at)

If you find that my work is worthy to be acknowledged, share your thoughts openly and publicly because by sharing public acknowledging over the value of my work is what will help me in order to find the attention from those able to allow me access to a job position or resources to increase the functionality of my research.


(This post is part of a more complex piece of independent research. I don´t have funding, 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, hereand 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)
