Resumen
El cambio climático abrupto, como los eventos de Dansgaard-Oeschger, está vinculado al enfriamiento del Atlántico Norte. La descarga de iceberg parece seguir, no causar, estas condiciones estadiales frías.
Área de la Ciencia:
- Paleoclimatología Paleoclimatología
- La dinámica del clima La dinámica del clima La dinámica del clima
- Oceanografía La oceanografía es la oceanografía.
Sus antecedentes:
- El clima del Pleistoceno tardío se caracterizó por cambios abruptos, incluidos los eventos de Dansgaard-Oeschger, caracterizados por cambios entre las condiciones cálidas interestadial y frío estadial.
- Estos eventos, registrados en los núcleos de hielo de Groenlandia, a menudo están relacionados con alteraciones en la circulación del Océano Atlántico.
- Los eventos fríos del Atlántico Norte se correlacionan con un aumento en el parto de icebergs, lo que provocó estudios de modelado climático utilizando el forzamiento de agua dulce.

01:50Global Climate Change
29.9K
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.

01:21Masonry in Cold and Hot Weather Conditions
388
In cold weather, masonry construction requires specific precautions to ensure mortar does not freeze before curing, as this can significantly weaken its strength and watertightness. Mortar temperature should be maintained between 60°F and 80°F to support proper hydration and curing. Below 40°F, mortar water must be heated, but should not exceed 120°F as high temperatures can reduce mortar's compressive and bond strength.

02:39Phase Transitions: Melting and Freezing
15.7K
Heating a crystalline solid increases the average energy of its atoms, molecules, or ions, and the solid gets hotter. At some point, the added energy becomes large enough to partially overcome the forces holding the molecules or ions of the solid in their fixed positions, and the solid begins the process of transitioning to the liquid state or melting. At this point, the temperature of the solid stops rising, despite the continual input of heat, and it remains constant until all of the solid is...

Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...

When a non-volatile solute is added to a pure solvent, it results in the lowering of the freezing point of the solvent. This phenomenon is called freezing point depression. The extent to which the freezing point is lowered depends on the molality of the solute -the number of moles of solute per kilogram of solvent and the cryoscopic constant of the solvent.From the plot of chemical potential, μ, against temperature, it is evident that the μ of both solid and liquid solvents decrease...

01:27Cold Weather Concreting
439
When freshly poured concrete is exposed to freezing temperatures before it has set, the water within the concrete can freeze. This expansion disrupts the setting process, delays chemical reactions necessary for hardening, and increases the volume of pores within the hardened concrete, which weakens its overall structure. If the concrete manages to reach an appreciable strength before it freezes, the damage can be somewhat mitigated.
