Resumen
La forestación global puede aumentar las precipitaciones tropicales pero disminuir la disponibilidad de agua boreal. La planificación de la forestación debe considerar estos impactos hidrológicos, especialmente en regiones de altas latitudes propensas a la escasez de agua.
Área de la Ciencia:
- Hidrología
- Ciencia Climática
- Ecología
Sus antecedentes:
- La forestación es una solución clave basada en la naturaleza para la mitigación del cambio climático.
- Sin embargo, las consecuencias hidrológicas y los patrones espaciales de la forestación a gran escala no se comprenden bien.
Objetivo del estudio:
- Investigar los efectos hidrológicos de la forestación potencial global.
- Analizar la divergencia latitudinal en las respuestas de la escorrentía y los mecanismos subyacentes.
Principales métodos:
- Se utilizaron modelos acoplados tierra-atmósfera y el marco de Budyko.
- Se analizaron las retroalimentaciones bosque-atmósfera y su influencia en la precipitación y la evapotranspiración.
Principales resultados:
- La forestación global induce una divergencia latitudinal en la escorrentía: aumentos en los trópicos y disminuciones en las regiones boreales.
- Los aumentos tropicales son impulsados por un aumento de las precipitaciones que supera el aumento de la evapotranspiración (ET).
- Las disminuciones boreales resultan de ganancias limitadas de precipitación que no compensan la mayor demanda evaporativa.
Conclusiones:
- Las retroalimentaciones bosque-atmósfera son críticas para determinar los impactos hidrológicos de la forestación.
- Las consideraciones hidrológicas son esenciales para las estrategias de forestación centradas en el carbono y la temperatura.
- Se aconseja precaución en la forestación de altas latitudes debido a la posible exacerbación de la escasez de agua.

01:50Global Climate Change
29.0K
Throughout its ~4.5 billion year history, the Earth has experienced periods of warming and cooling. However, the current drastic increase in global temperatures is well outside of the Earth’s cyclic norms, and evidence for human-caused global climate change is compelling. Paleoclimatology, the study of ancient climate conditions, provides ample evidence for human-caused global climate change by comparing recent conditions with those in the past.

Biochemical reactions are occurring constantly in cells, converting starting substances to different products, usually with the help of enzymes that speed the reactions. Without enzymes, it would take far too long for most reactions to occur to be useful to the cell!

01:15Divergence and Curl
3.3K
The divergence of a vector field at a point is the net outward flow of the flux out of a small volume through a closed surface enclosing the volume, as the volume tends to zero. More practically, divergence measures how much a vector field spreads out or diverges from a given point. For an outgoing flux, conventionally, the divergence is positive. The diverging point is often called the "source" of the field. Meanwhile, the negative divergence of a vector field at a point means that the vector...

3.8K
The divergence and Stokes' theorems are a variation of Green's theorem in a higher dimension. They are also a generalization of the fundamental theorem of calculus. The divergence theorem and Stokes' theorem are in a way similar to each other; The divergence theorem relates to the dot product of a vector, while Stokes' theorem relates to the curl of a vector. Many applications in physics and engineering make use of the divergence and Stokes' theorems, enabling us to write...

02:37Gene Duplication and Divergence
8.0K
The seminal work of Ohno in 1970 popularized the idea of gene duplication and divergence. DNA sequence comparison studies reveal that a large portion of the genes in bacteria, archaebacteria, and eukaryotes was generated by gene duplication and divergence, indicating its critical role in evolution.
The duplicated copies of the gene are called Paralogs. Paralogs with similar sequences and functions form a gene family. Across several species, a large number of gene families are...

In most cases, excessive hormone production is prevented by negative feedback—a loop that starts with a stimulus inducing the release of a particular substance, like a hormone, to maintain a certain level before triggering a signal that results in a decrease in further release of the hormone.
