In her lengthy and data -rich paper, Mishra et al. . The precipitation should contribute 45% to this green and the groundwater pumps 55%. While this credit is fascinating, what is really shocking is what is not mentioned in general: CO2 fertilization.
The term “carbon dioxide”, “CO₂” or even “fertilization” does not occur once. This despite the well-documented global evidence that increased atmospheric CO₂-CO₂ increases plant growth by improving photosynthesis and improving the efficiency of water use. Like Piao et al. (2019) in Nature Reviews Earth & Environment: “Vegetation models indicate that the CO2 fertilization of the main drivers for greening is on a global scale. This fact seems to have escaped the attention of this research team.
The Thar desert, a dry land environment with historically marginal vegetation, is exactly the kind of region in which CO2 fertilization effects would be the most. Plants under water -limited conditions often react vigorously to increased CO2, since they can use less stomatal opening more photosyntheticize, which reduces water loss. However, the role of CO2 is invisible in a paper that examines the vegetation dynamics to the pixel level.
Graphic summary
This omission is not an academic supervision, symptomatic for a broader trend in climate-use literature: selective attribution, where natural drivers that contradict apocalyptic stories are ignored in favor of ideologically more explanatory explanations such as “renewable energies” and “adaptation”.
The other eyebrow deduction of the paper is its repeated, ritual call from renewable energy As a necessary solution for sustainability – without empirical justification or economic justification.
“Sustainable practicing-efficient water management, drought-resistant plants, adaptation to increasing heat load and renewable energy—Must Futing Future Development. “
Do you have to? Which economic model or energy system analysis? No cost-benefit analysis is created. No energy return (EROI) data. No raster reliability ratings. No life cycle -mpact comparisons. Only a declarative sentence.
The authors write later:
“Semi-arid and dry countries such as the Thar are ideal for grasping solar energy … to emphasize the potential role of the sun pump for the GW abstraction.”
Yes, the sun shines in the desert. However, this simplified correlation completely avoids the critical challenges: capital intensity, energy storage, intermittenz and the massive material and ecological footprint of solar installations in fragile desert ecosystems. It is not mentioned how a renewable infrastructure is maintained in remote, dusty, high -temperature areas, which are known for the deterioration in photovoltaic performance.
Rajasthan already sees Groundwater raving in the event of not sustainable installmentsMuch of it driven by energy -intensive tubes that is well pumped. The replacement of one energy source does nothing to repair the basic overuse of water. But it serves the narrative function of the paper: Renewable energies = good, fossil fuels = badDamn evidence.
The paper is a model case study of how environmental sciences often smuggle into Ideological preferences Under the guise of objective reporting. For example, it tells us ::
“Global drying areas offer various options for climate improvement, including carbon binding, modification of aerosol cloud dynamics, maintaining biological diversity and improvement in renewable energies.”
Here, too, there is no quantification or evaluation of compromises. Sun collectors do not follow the carbon. They will not preserve the biological diversity – they require the land. They do not modify aerosol cloud dynamics (a pseudo-scientific red herring if there was ever one). However, these sentences roll off the side and calm the readers that the correct moral lessons have been internalized.
Models, monsoons and lack of science
The green of the Thar desert is a fascinating phenomenon. It is a counter-narrative on the prevailing stupid stories about desert formation and ecological collapse. But the authors of this paper don't seem to be ready to follow the data where it leads. Instead, they return their drivers (rain and pumps), ignore the most obvious (CO2) and end with a sermon on renewable energies, which is completely separated from the empirical core of the study.
What a strong observation study could have been is instead impaired by Narrative conformity. In today's world of environmental sciences it is apparently more taboo to say that “CO2 helps” or “renewable energies may not be the answer” than they do not mention at all.
For those who are looking for strict, reality-related environmental sciences, this paper is a warning history-Roadmap for sustainable development.
