Summary
Climate change mitigation involves reducing greenhouse gas emissions. This study reviews technologies, including microalgae cultivation, for absorbing atmospheric carbon dioxide (CO2) to meet Paris Agreement targets.
Area of Science:
- Environmental Science
- Climate Science
- Biotechnology
Background:
- Global climate change necessitates mitigation strategies to reduce greenhouse gas (GHG) emissions.
- Atmospheric carbon dioxide (CO2) concentrations are rising, potentially exceeding the 450 ppm target for limiting global warming to 2 °C.
- The Paris Agreement requires achieving near-zero emissions and significant CO2 absorption by 2070.
Purpose of the Study:
- To provide a comprehensive overview of current climate change mitigation technologies.
- To analyze the potential of microalgae cultivation as a negative emission technology for CO2 biofixation.
Main Methods:
- Review of existing climate change mitigation technologies.
- Analysis of microalgae cultivation for large-scale CO2 absorption.
Main Results:
- Various mitigation technologies exist to reduce or absorb GHGs, particularly CO2.
- Negative emission technologies are crucial for achieving substantial atmospheric CO2 removal.
- Microalgae massive cultivation is identified as an emergent negative emission technology with significant CO2 biofixation potential.
Conclusions:
- Achieving climate targets requires both emission reduction and active CO2 removal from the atmosphere.
- Negative emission technologies, such as microalgae cultivation, are essential for meeting future climate goals.
- Further research and implementation of microalgae biofixation are necessary for effective climate change mitigation.

01:50Global Climate Change
27.0K
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.

01:16What is Climate?
19.5K
Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

01:57Adaptations that Reduce Water Loss
27.0K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.

01:17Design Example: Analyzing Capacity Contours for Flood Risk Assessment
162
Flood risk assessment involves careful planning and analysis to ensure the safety of communities near water retention structures. Capacity contours are a vital tool in this process, as they illustrate the potential spread of water at specific levels in a given area. In the context of building a bund across a small valley, these contours play a critical role in evaluating the safety of nearby residential areas.In this example, the bund is intended to store stormwater in the valley.

01:17Radiation: Applications
1.3K
The average temperature of Earth is the subject of much current discussion. Earth is in radiative contact with both the Sun and dark space; it receives almost all its energy from the radiation of the Sun and reflects some of it into outer space. Dark space is very cold, about 3 K, so Earth radiates energy into it. For instance, heat transfer occurs from soil and grasses, the rate of which can be so rapid that frost can occur on clear summer evenings, even in warm latitudes.

GIS manipulation and analysis functions are vital for decision-making and planning. These activities range from data retrieval tasks, such as selecting information based on specific criteria, to advanced analytical techniques that address complex spatial problems.One critical GIS analysis method is overlaying, which combines multiple data layers to examine impacts. For example, overlaying a river-dammed lake boundary with road networks can identify affected infrastructure. Another common...
