Global Climate Change01:50

Global Climate Change

28.4K
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.

Carbon Dioxide Transport in the Blood01:19

Carbon Dioxide Transport in the Blood

4.2K
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...

The Carbon Cycle01:14

The Carbon Cycle

43.0K
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.

Assessment of Diffusion and Perfusion01:17

Assessment of Diffusion and Perfusion

1.5K
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.
The Role of Diffusion in Respiration
Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration. In the respiratory system, this...

Carbon-dioxide Fixation01:28

Carbon-dioxide Fixation

525
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...

Phase Diagrams02:39

Phase Diagrams

47.9K
A phase diagram combines plots of pressure versus temperature for the liquid-gas, solid-liquid, and solid-gas phase-transition equilibria of a substance. These diagrams indicate the physical states that exist under specific conditions of pressure and temperature and also provide the pressure dependence of the phase-transition temperatures (melting points, sublimation points, boiling points). Regions or areas labeled solid, liquid, and gas represent single phases, while lines or curves represent...

Area of Science:

  • Environmental Science
  • Climate Science
  • Energy Policy

Background:

  • China is the world's largest energy consumer and CO2 emitter, contributing around 30% of global emissions.
  • Accurate CO2 emission data is vital for effective carbon policies and international climate change mitigation efforts.

Purpose of the Study:

  • To construct the most up-to-date CO2 emission inventories for China and its 30 provinces for the years 2016 and 2017.
  • To update and supplement existing emission datasets for the period 1997-2015.
  • To provide detailed energy and sector-specific emission data for policy analysis and climate modeling.

Main Methods:

  • Calculated CO2 emissions based on the Intergovernmental Panel on Climate Change (IPCC) guidelines.
  • Included energy-related emissions from 17 fossil fuel types and process-related emissions from cement production.
  • Compiled inventories for 47 economic sectors aligned with China's national economic accounting system.

Main Results:

  • Developed the latest CO2 emission inventories for China and its provinces for 2016-2017.
  • The inventories cover all anthropogenic emissions within administrative boundaries due to energy consumption and industrial processes.
  • Data provides crucial updates to the 1997-2015 emission dataset.

Conclusions:

  • The newly compiled inventories offer a comprehensive resource for understanding China's emission patterns.
  • Data serves as essential input for climate and integrated assessment models.
  • Findings support the development of targeted carbon policies and global climate change mitigation strategies.
