introduction to the climate change and its causes
Imagine the temperature of the sun were to decrease. Discuss the impacts this would have on a component of the global energy balance and the concept of climate change.
Impacts of Temperatures of the Sun on Earth’s Energy Balance and Climate Change
Extreme weather events, variability and long term climate parameter changes affect the energy system components and hence its balance. Other than gravitational energy, the earth’s energy system is sustained by solar energy. When the earth absorbs radiated solar energy, it warms up and there is an increase in its temperature (Union of Concerned Scientists, 2017). This paper seeks to evaluate the impact of the reduction in the temperatures of the sun on global radiation component of the global energy balance and the climate change impact.
According to Asrat and Parker (2017), blocking of the sun has been established as one of the solar radiation management methods and hence solutions to global warming. The process entails blocking part of sunlight emitted to the earth’s surface to quickly mitigate global warming risks. When the sun is blocked, the amount of energy radiated into the atmosphere will be reduced considerably, hence mitigating most of the climate change risks globally. Some of the risks contained by a reduction of the temperatures of the sun include temperature rise, rainfall disruption, sea level rising, and increased intensity of the storm. Although the effects of a reduction in temperature are not uniformly distributed, the consequent is a non-linear but desirable solar radiation management.
A reduction in temperatures of the sun may have unknown negative impacts on solar radiation and climate change at large (Asrat & Parker, 2017). These effects are a result of the complex climatic system of the planet that is difficult to predict and are subject to natural variations. Besides, the drastic temperature falls may mean that all heat is absorbed by the earth’s core hindering any radiation (Union of Concerned Scientists, 2017). The implication is global cooling which may also impact the climate negatively by prolonging cold seasons such as winter.
In conclusion, the sun is a major force driving the earth’s climate. The implication is that even slight changes in the energy levels received by the earth can significantly affect the global radiation and consequently the energy balance. Although this does not pose a short-term threat to climate, in the long-run, reduction in the solar energy absorbed and radiated by the earth reduces its temperatures and consequently causes variation in climate change.
