Summary
Canada
Area of Science:
- Environmental Economics
- Industrial Ecology
- Climate Change Analysis
Background:
- Global supply chains increasingly complicate national carbon footprints.
- Understanding embodied carbon in trade is crucial for climate policy.
Purpose of the Study:
- To analyze Canada's embodied CO2 emissions in exports (EEE) from 2000-2018.
- To identify key drivers and pathways of Canada's EEE.
- To inform targeted emission mitigation strategies.
Main Methods:
- Combined World Input-Output Database and ADB's Multiregional Input-Output database.
- Employed structural decomposition analysis and structural path analysis.
- Investigated emission intensity, export structure, and export scale.
Main Results:
- Intermediate exports are the primary source of Canada's EEE.
- Complex, multi-country emission pathways are increasing.
- Energy and resource sectors significantly contribute to embodied emissions.
Conclusions:
- Emission regulations must account for sectoral differences and supply chain dynamics.
- Whole life-cycle and integrated supply chain governance are essential for effective abatement.
- Balancing emission intensity reductions with export scale is critical.

01:19Carbon Dioxide Transport in the Blood
6.7K
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...

01:14The Carbon Cycle
32.8K
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.

Understanding and evaluating diffusion and perfusion is critical in assessing a patient's respiratory and circulatory health. These processes play key roles in maintaining the body's internal environment, ensuring that tissues receive adequate oxygen while waste products are efficiently removed.

01:50Global Climate Change
24.3K
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.

01:20Gas Exchange and Transport
73.1K
Gas exchange, the intake of molecular oxygen (O2) from the environment and the outflow of carbon dioxide (CO2) into the environment, is necessary for cellular function. Gas exchange during respiration occurs largely via the movement of gas molecules along pressure gradients. Gas travels from areas of higher partial pressure to areas of lower partial pressure. In mammals, gas exchange occurs in the alveoli of the lungs, which are adjacent to capillaries and share a membrane with them.

02:14Combustion Energy: A Measure of Stability in Alkanes and Cycloalkanes
6.2K
The low reactivity in alkanes can be attributed to the non-polar nature of C–C and C–H σ bonds. Alkanes, therefore, were initially termed as “paraffins,” derived from the Latin words: parum, meaning “too little,” and affinis, meaning “affinity.”
Alkanes undergo combustion in the presence of excess oxygen and high-temperature conditions to give carbon dioxide and water. A combustion reaction is the energy source in natural gas, liquified...
