The Carbon Cycle

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.

Bioremediation

Bioremediation

Bioremediation is the use of prokaryotes, fungi, or plants to remove pollutants from the environment. This process has been used to remove harmful toxins in groundwater as a byproduct of agricultural run-off and also to clean up oil spills.

Global Climate Change

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: Applications

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.
The average...

Microbes and the Carbon Cycle

Microbes and the Carbon Cycle

The carbon cycle is a fundamental Earth process involving the transfer of carbon among the biosphere, lithosphere, atmosphere, and hydrosphere. It plays a critical role in regulating the planet’s climate and supporting life by cycling carbon through various chemical forms and reservoirs. Carbon primarily circulates as carbon dioxide (CO₂), representing its oxidized form, while reduced forms such as methane (CH₄) and organic compounds also play essential roles.Microbial activity is central to...

Microbes and Climate Change

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...

Background:

Aerosols, particularly black carbon, are increasingly recognized for their significant climatic impacts.
Research explores reducing black carbon emissions as a climate change mitigation strategy.
Scientific debate exists regarding the inclusion of aerosols and greenhouse gases in common climate frameworks due to differing mechanisms and timescales.

Purpose of the Study:

To review arguments for and against a common framework for aerosols and greenhouse gases in climate change mitigation.
To synthesize climate modeling results to determine the global warming potential of black carbon relative to CO2.
To discuss the cost-effectiveness of black carbon mitigation strategies and propose a role within broader climate agreements.

Main Methods:

Literature review of scientific arguments concerning aerosol and greenhouse gas climate impacts.
Synthesis of published climate-modeling studies to calculate the global warming potential (GWP) of black carbon.
Analysis of cost-effectiveness for mitigating major black carbon emission sources.

Main Results:

A calculated 100-year global warming potential for black carbon relative to CO2 is 680.
Mitigation of black carbon emissions can be expensive or challenging, especially for Annex I countries.
A framework is proposed for integrating black carbon mitigation into climate strategies.

Conclusions:

Despite differing physical mechanisms and timescales, a joint consideration of aerosols and greenhouse gases is compatible with the UNFCCC.
Addressing black carbon emissions presents a promising avenue for climate mitigation, particularly for nations not yet committed to greenhouse gas reductions.
Black carbon mitigation can serve as a parallel climate agreement, offering co-benefits and reducing climatic interference.
