Resumen
La actividad humana ha alterado de manera demostrable los patrones de precipitación global, afectando a regiones de todo el mundo. Estos cambios detectados en las precipitaciones son más pronunciados de lo que los modelos climáticos predijeron, afectando a los ecosistemas y a las poblaciones humanas.
Área de la Ciencia:
- Ciencias del clima Ciencias del clima Ciencias del clima
- Ciencias de la atmósfera Ciencias atmosféricas.
- Ciencias ambientales Ciencias ambientales.
Sus antecedentes:
- La influencia humana en el cambio climático se ha detectado previamente en varios indicadores como la temperatura y el contenido de calor del océano.
- La detección de la influencia humana en la precipitación global ha sido un desafío debido a las variaciones regionales que anulan la señal promedio global.
- Los modelos climáticos predicen que el forzamiento antropogénico debería causar un aumento de la precipitación media global y la redistribución latitudinal.

01:50Global Climate Change
24.4K
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.

01:21Precipitation Titration Curve: Analysis
2.1K
The precipitation titration curve demonstrates the change in concentration of one reactant with the volume of titrant added. During the titration of chloride ions with silver nitrate, the precipitation titration curve is divided into three regions: before, at, and after the equivalence point. Before the equivalence point, low redissolution of the sparingly soluble silver chloride precipitate gives a low silver ion concentration. However, in the second region, representing the equivalence point,...

01:19Precipitation Titration: Endpoint Detection Methods
5.1K
In argentometric precipitation titrations, endpoints can be detected visually by the Mohr, Volhard, and Fajans methods. In the Mohr method, adding a soluble chromate indicator gives an initial yellow color to the analyte solution. As the titrant is added, the first excess of silver ions forms a red silver chromate precipitate, marking the endpoint. The solution pH should be maintained at about 8 by adding solid CaCO3.

01:03Precipitation Gravimetry
12.8K
Precipitation gravimetry is based on converting an analyte into a sparingly soluble precipitate, which is separated by filtration and weighed. An ideal precipitate should be pure, insoluble, of known composition, and easily filtered from the reaction mixture.
In determining nickel by gravimetric analysis, a precipitant of ethanolic dimethylglyoxime is added to a hot nickel salt solution. This is quickly followed by the dropwise addition of dilute ammonia solution until precipitation occurs. A...

01:12Precipitation Processes
5.0K
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...

01:17Precipitation and Co-precipitation
4.8K
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...
