Reducing Global Warming
Introduction:
Scientists have suggested the use of cirrus cloud thinning technique and the injection of Sulphate aerosol into the stratosphere as a means to reduce global warming. These techniques aim to mitigate the adverse effects of climate change by altering the Earth's energy balance.
Global Warming:
Global warming refers to the long-term increase in the Earth's average surface temperature due to the accumulation of greenhouse gases in the atmosphere. This increase in temperature is primarily caused by human activities such as the burning of fossil fuels, deforestation, and industrial processes.
Cirrus Cloud Thinning Technique:
Cirrus clouds are high-altitude clouds composed of ice crystals. They have a warming effect on the Earth's surface as they trap outgoing longwave radiation. By thinning these clouds, scientists aim to reduce their warming effect and allow more longwave radiation to escape into space.
Injection of Sulphate Aerosol into Stratosphere:
Sulphate aerosols, when injected into the stratosphere, can reflect a portion of the incoming solar radiation back into space. This reflection of sunlight can have a cooling effect on the Earth's surface, counteracting the warming caused by greenhouse gases.
Scientific Rationale:
The cirrus cloud thinning technique and the injection of Sulphate aerosol into the stratosphere are proposed as geoengineering solutions to reduce global warming. These techniques aim to artificially modify the Earth's climate system to offset the warming caused by greenhouse gas emissions.
Challenges and Risks:
While these techniques may have the potential to reduce global warming, they also come with significant challenges and risks. The long-term impacts of manipulating the Earth's climate system are still not fully understood, and there is a potential for unintended consequences. Additionally, implementing these techniques on a global scale would require significant resources and international cooperation.
Conclusion:
In conclusion, some scientists suggest the use of cirrus cloud thinning technique and the injection of Sulphate aerosol into the stratosphere as a means to reduce global warming. These techniques aim to alter the Earth's energy balance by reducing the warming effect of cirrus clouds and reflecting sunlight back into space. However, the implementation of these techniques comes with challenges and risks that need to be carefully evaluated before considering their widespread use.

Explanation: Cirrus cloud thinning is a proposed form of climate engineering. Cirrus clouds are high cold ice that, like other clouds, both reflect sunlight and absorb warming infrared radiation. However, they differ from other types of clouds in that, on average, infrared absorption outweighs sunlight reflection, resulting in a net warming effect on the climate. Therefore, thinning or removing these clouds would reduce their heat trapping capacity, resulting in a cooling effect on Earth's climate. This could be a potential tool to reduce anthropogenic global warming. Cirrus cloud thinning is an alternative category of climate engineering, in addition to solar radiation management and greenhouse gas removal. Solar Winds have hardly any significant impact on earth hence it is incorrect.
Reducing the frequency and intensity of tropical cyclones requires altering ocean water temperatures which is humanly impossible and hence is incorrect.
Artificial rains are created by spraying Dry Ice(solid carbon dioxide), Silver Iodide, Salt powder etc. on the rain bearing clouds. Hence it is incorrect.
Educational Objective: Test candidate's knowledge of various methods being suggeted to reduce the effect of global warming.
