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.

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.

What are Biogeochemical Cycles?

What are Biogeochemical Cycles?

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.

The Sulfur Cycle

The Sulfur Cycle

Sulfur, an important element in the chemical makeup of proteins, is recycled through the atmosphere and aquatic and terrestrial environments. Found in the atmosphere as sulfur dioxide (SO2), sulfur is released by decaying organisms, weathered rocks, geothermal vents, volcanos, and burning fossil fuels. It is deposited into the ecosystem, cycled through the biotic community, and either released back into the atmosphere as gas or deposited in marine sediment for long-term storage and eventual...

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.

Plasticizers

Plasticizers

Water-reducers, or plasticizers, are chemical admixtures used in concrete to improve strength and workability. These additives reduce the water-cement ratio without compromising workability, lower the cement content while maintaining the same workability, or increase workability to assist concrete placement in inaccessible areas.
Plasticizers function by using surface-active agents to create repulsive electrostatic forces between cement particles. This dispersion enhances the concrete's...

Area of Science:

Environmental Science
Machine Learning
Oceanography

Background:

Marine plastic pollution poses significant threats to ecosystems and human health.
Limited data on coastal plastic sources hinders effective pollution control strategies.

Purpose of the Study:

To develop a machine learning framework for quantifying and mapping coastal plastic pollution.
To establish a Coastal Plastic Pollution Index (CPPI) for classifying pollution severity.

Main Methods:

Utilized a machine learning framework with 25,892 data points from 3,468 coastal sites.
Incorporated 38 features, including socioeconomic data, waste types, geomorphology, and tidal characteristics.
Applied unsupervised learning for data clustering and CPPI distribution analysis.

Main Results:

Estimated global coastal plastic emission in 2019 between 15.32 and 59.18 kilotons.
Identified mismanaged plastic waste, plastic waste generation, and specific packaging types (PET, PP) as major contributors.
Found consistent CPPI distribution among countries within the same identified clusters.

Conclusions:

The developed framework provides a robust method for assessing coastal plastic pollution.
Findings support targeted national and international policies for marine plastic mitigation.
The CPPI offers a standardized approach to evaluating pollution severity at coastal input sites.
