Resumen
Las precipitaciones de África Central en los últimos 20.000 años fueron impulsadas principalmente por las diferencias de temperatura de la superficie del mar del Atlántico Sur. Los cambios en la circulación oceánica influyeron significativamente en el transporte de humedad a la región.
Área de la Ciencia:
- Paleoclimatología Paleoclimatología
- Hidrología Hidrología Hidrología.
- Oceanografía La oceanografía es la oceanografía.
Sus antecedentes:
- Los cambios hidrológicos africanos son regional y temporalmente diversos, influenciados por factores como las precipitaciones impulsadas por los monzones y las anomalías de la temperatura de la superficie del mar.
- Los cambios en las precipitaciones pasadas en el norte y el sur de África están vinculados a la insolación precesional, mientras que los cambios en el norte de África tropical se correlacionan con las temperaturas superficiales del mar del Atlántico Norte.
- Comprender los cambios hidrológicos a gran escala en África ecuatorial y sus impulsores sigue siendo un desafío.

01:50Global Climate Change
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.
01:16What is Climate?
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.
01:12Precipitation Processes
The experimental conditions in a gravimetric analysis should be optimized to maximize the particle size and purity of the obtained precipitate. Ideally, the concentration of the precipitating reagent should be low with effective stirring to maintain low relative supersaturation for the growth of large crystals. In homogeneous precipitation, the precipitant is slowly generated by a chemical reaction in the solution to avoid local reagent excesses. For example, urea decomposes gradually to...
01:27Microbes and Climate Change
Microorganisms are pivotal agents in Earth's biogeochemical cycles, significantly influencing climate dynamics through their metabolic activities. These microbes modulate the levels of key greenhouse gases by both contributing to and helping mitigate climate change.Microbial Contributions to Greenhouse Gas EmissionsRising global temperatures accelerate microbial metabolism, which, in turn, speeds up the decomposition of organic matter. This process releases carbon dioxide (CO₂) through...
01:17Precipitation and Co-precipitation
Precipitation and coprecipitation methods can be used to separate a mixture of ions in a solution. In qualitative inorganic analysis, ions that form sparingly soluble precipitates with the same reagent are separated based on the differences in solubility products. For example, consider the separation of Cu(II) and Fe(II) ions by precipitation as insoluble sulfides. First, copper(II) sulfide is precipitated by the addition of acidic H2S, where the dissociation of H2S is suppressed. Adding H2S...
01:57Adaptations that Reduce Water Loss
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
