Resumen
Las grandes erupciones volcánicas impactaron significativamente las temperaturas del hemisferio norte en los últimos 2.500 años, impulsando la variabilidad climática interanual a decadal. Nuevos datos de núcleos de hielo resuelven las inconsistencias de tiempo, vinculando las erupciones a cambios climáticos y eventos históricos.
Área de la Ciencia:
- Paleoclimatología Paleoclimatología
- Ciencias del clima Ciencias del clima Ciencias del clima
- Volcanología Volcanología.
Sus antecedentes:
- Cuantificar los impactos volcánicos en la variabilidad climática es un desafío debido a las discrepancias entre los datos de aerosol de núcleos de hielo y los registros proxy climáticos.
- Las inconsistencias en la datación de la carga de aerosoles volcánicos atmosféricos y el posterior enfriamiento impiden una atribución precisa del cambio climático.

01:50Global Climate Change
29.8K
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.

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...

01:16What is Climate?
21.5K
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.

01:21Isothermal Processes
5.4K
A thermodynamic process that occurs at constant temperature is called an isothermal process. Heat slowly flows into the system or out of the system to maintain thermal equilibrium. Processes involving phase changes like water evaporation into steam or freezing water into ice at a constant temperature are examples of Isothermal Processes.
An ideal gas can also undergo isothermal expansion or compression.
For example, consider 1 mole of an ideal gas inside an isolated cylinder at initial volume V...

01:12Setting Time of Cement
984
The setting time of cement refers to the process of cement paste transitioning from a plastic state to a solid state. This process is crucial in construction as it dictates the timeframe for concrete placement, compaction, and finishing. The onset of this solidification is termed the initial set, indicating when the paste becomes unworkable. The final set is when the paste has solidified completely, and further handling or manipulation can no longer affect its shape. The cement strength is...

01:12Precipitation Processes
6.6K
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...
