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.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Sampling Plans

Sampling Plans

Sampling is a crucial step in analytical chemistry, allowing researchers to collect representative data from a large population. Common sampling methods include random, judgmental, systematic, stratified, and cluster sampling.
Random sampling is a method where each member of the population has an equal chance of being selected for the sample. It involves selecting individuals randomly, often using random number generators or lottery-type methods. For example, when analyzing the properties of a...

Environmental Applications of Microorganisms

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

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...

Summary

This summary is machine-generated.

Despite US federal non-participation in the Kyoto Protocol, sub-national policies addressing greenhouse-gas emissions are significant. These efforts involve 24-35% of the US population and impact 27-49% of GDP.

Area of Science:

Environmental Science
Climate Policy
US Environmental Studies

Background:

The United States' absence from the Kyoto Protocol is a global concern due to its significant contribution (24%) to worldwide greenhouse-gas emissions.
Anthropogenic climate change necessitates international cooperation and national policy commitments.

Purpose of the Study:

To analyze the commitment of US states and municipalities to climate change mitigation policies.
To quantify the population and economic impact of sub-national climate change initiatives.

Main Methods:

Analysis of state and municipal policies related to greenhouse-gas emission reduction.
Estimation of the percentage of the US population and Gross Domestic Product (GDP) involved in these policies.

Main Results:

Between 24% and 35% of the US population is engaged in or will soon be engaged in policies aimed at significantly reducing climate change.
These sub-national efforts represent a substantial portion of the US economy, estimated at 27-49% of GDP.

Conclusions:

Sub-national actions in the US demonstrate a significant commitment to addressing climate change, despite federal policy.
The ultimate success of these climate policies hinges on achieving real reductions in greenhouse-gas emissions, similar to national targets.
