The Carbon Cycle01:14

The Carbon Cycle

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.

What is Climate?01:16

What 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.
Global Climate Change01:50

Global 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.
Radiation: Applications01:17

Radiation: Applications

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.

Microbes and Climate Change01:27

Microbes 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...

    Area of Science:

    • Planetary Science
    • Climate Science
    • Geology

    Background:

    • Equatorial sinuous channels on Mars suggest past liquid water and higher atmospheric pressure.
    • Martian climate stability is influenced by atmospheric advective instability.

    Purpose of the Study:

    • To investigate the potential for stable, clement climates on Mars in its past.
    • To explore mechanisms driving climatic shifts on Mars.

    Main Methods:

    • Analysis of atmospheric advective instability.
    • Modeling of climate dynamics based on obliquity, solar luminosity, and polar cap albedo.

    Main Results:

    • Two stable Martian climates identified: one near-present, another at ~1 bar pressure.
    • Variations in Mars' obliquity, solar luminosity, and polar cap albedo can trigger climate shifts.
    • Obliquity variations alone suggest significant past pressure fluctuations.

    Conclusions:

    • Mars has experienced dramatic climate changes throughout its history.
    • These climatic shifts have profound implications for Martian meteorology, geology, and potential biology.
