The Carbon Cycle01:14

The Carbon Cycle

44.0K
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.

Carbon Skeletons01:12

Carbon Skeletons

115.5K
Life on Earth is carbon-based, as all macromolecules that make up living organisms contain carbon atoms. All organic compounds have a carbon backbone. Each carbon atom is tetravalent and can bond with four other atoms, making it an extraordinarily flexible component of biological molecules. Because carbon’s valence electrons are stable, it rarely becomes an ion. As the carbon chain increases in length, structural modifications such as ring structures, double bonds, and branching side...

Carbonation Shrinkage01:24

Carbonation Shrinkage

501
Atmospheric CO2 penetrates the concrete's pores and, in the presence of moisture, forms carbonic acid, which then reacts with calcium hydroxide in the hydrated cement, forming calcium carbonate. This process reduces the concrete's volume and is termed carbonation shrinkage.
The concrete's permeability is slightly reduced as calcium carbonate produced during the reaction fills its pores. Furthermore, its strength is slightly enhanced as the water released during the reaction...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

735
Carbon dioxide fixation in prokaryotes enables the assimilation of inorganic carbon into organic molecules, supporting biosynthetic pathways, sustaining ecosystems, and contributing to the global carbon cycle. It also has industrial applications in carbon capture and bioproduct synthesis. Autotrophic organisms rely on this process to utilize CO₂ as a carbon source in diverse environments.The Calvin CycleThe Calvin cycle is the most widespread carbon fixation mechanism, primarily used by...

Carbon-13 (¹³C) NMR: Overview01:10

Carbon-13 (¹³C) NMR: Overview

7.8K
Carbon-13 is a naturally occurring NMR-active isotope of carbon with a low natural abundance of 1.1%. In contrast, carbon-12 is the most abundant isotope of carbon with zero nuclear spin. Therefore, it is NMR inactive. The gyromagnetic ratio of carbon-13 is smaller than that of protons. As a result, carbon-13 resonance is about 6000 times weaker than proton resonance. For a given magnetic field strength, the resonance frequency of carbon-13 is about one-fourth of the resonance frequency for...

Carbon Dioxide Transport in the Blood01:19

Carbon Dioxide Transport in the Blood

5.3K
Carbon dioxide (CO2) transport in the blood is critical to human physiology. On average, our body cells produce around 200 mL of CO2 per minute, precisely the quantity expelled by the lungs. This process involves the transportation of CO2 from the tissue cells to the lungs in three primary forms.
Forms of CO2 Transport
1. Dissolved in plasma: A small percentage (7-10%) of CO2 is transported and dissolved directly in the plasma.
2. Carbaminohemoglobin: Just over 20% of CO2 is chemically bound to...

Summary
This summary is machine-generated.

Most people lack basic carbon numeracy, underestimating the carbon dioxide (CO2) released from burning gasoline. Improving quantitative understanding of carbon footprints is crucial for effective environmental policies and sustainable decisions.

Area of Science:

  • Environmental Science
  • Behavioral Economics
  • Climate Change Communication

Background:

  • Effective environmental policies require individuals to understand the carbon footprint of their daily choices.
  • A lack of quantitative understanding, or carbon numeracy, hinders sustainable decision-making.

Purpose of the Study:

  • To investigate individuals' ability to accurately estimate the carbon dioxide (CO2) emissions from everyday activities, specifically gasoline combustion.
  • To assess the public's carbon numeracy in comparison to familiar metrics like food calories and travel distance.

Main Methods:

  • Three studies were conducted with varying scales and sample sizes.
  • Participants were asked to estimate CO2 emissions from burning one gallon of gasoline and compare it to other common metrics.
  • Statistical analysis was used to evaluate the accuracy of estimations and identify systematic biases.

Main Results:

  • Respondents consistently demonstrated significantly lower accuracy when estimating CO2 emissions from gasoline combustion compared to other metrics.
  • A prevalent tendency to underestimate the CO2 released from gasoline was observed across all studies.
  • This lack of carbon numeracy was evident even for basic consumption habits.

Conclusions:

  • The widespread innumeracy regarding carbon footprints may impede the success of environmental policies and public awareness campaigns.
  • There are opportunities for policy design to enhance public quantitative understanding of carbon footprints.
  • Improving carbon numeracy is essential for fostering more effective individual engagement with sustainability efforts.
