Resumen
Los cambios en la circulación oceánica provocaron fluctuaciones en el dióxido de carbono (CO2) y el óxido nitroso (N2O) atmosféricos durante los períodos glaciales. Estos cambios influyeron en los cambios climáticos a escala milenaria, impactando las temperaturas de Groenlandia y la Antártida.
Área de la Ciencia:
- Paleoclimatología Paleoclimatología
- Los ciclos biogeoquímicos son ciclos biogeoquímicos.
- Modelado del clima en el modelo climático.
Sus antecedentes:
- El clima de la Tierra y las concentraciones de gases de efecto invernadero (CO2 y N2O) fluctuaron significativamente en escalas de tiempo milenarias durante los períodos glaciales.
- Los grandes y rápidos eventos de calentamiento en Groenlandia se correlacionaron con N2O, mientras que los cambios de temperatura en la Antártida se correlacionaron con CO2.

00:54What are Biogeochemical Cycles?
31.1K
The most common elements in organic molecules, carbon, hydrogen, oxygen, nitrogen, sulfur, and phosphorus, are only available in the ecosystem in limited amounts. Therefore, these nutrients must be recycled through both biotic and abiotic components of the ecosystem, in processes generally called biogeochemical cycles.

01:14The Carbon Cycle
32.8K
Carbon is the basis of all organic matter on Earth, and is recycled through the ecosystem in two primary processes: one in which carbon is exchanged among living organisms, and one in which carbon is cycled over long periods of time through fossilized organic remains, weathering of rocks, and volcanic activity. Human activities, including increased agricultural practices and the burning of fossil fuels, has greatly affected the balance of the natural carbon cycle.

01:16What is Climate?
17.5K
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.

01:50Global 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.

01:17Radiation: Applications
1.8K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

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...
