A new study has found the impact of Sun on the earth's climate change. It says that there is a possibility that the solar activities are contributing physically for the first time on the earth's climatic fluctuations.
According to Phys.org, the sun might not be beating down so heavily on the earth in the next few decades, thus decreasing the "human-induced" global warming to some extent. Scientists are of the opinion that the amount of sunlight reaching the earth increases or decreases with the intensity of solar activity. Researchers are making efforts to find out whether this fluctuation directly impacts the earth's climate changes or not.
The new calculations have predicted that for the very first time, earth might experience a fall in its temperature by half a degree over the next 100 years as solar activities reach a minimum level. Researchers opine that this might help in slowing down the effects of global warming and buy the earth some valuable time to fight the ill-effects. This particular climate change is being considered to be very significant by the scientists, as it might be followed by a huge rise in temperature.
According to the Union of Concerned Scientists, TSI or "Total Solar Irradiance", the rate at which the energy from the sun reaches the earth's atmosphere, varies with season, day time and latitude. Researchers are of the opinion that rate of change in TSI is quite significant to the climate change, however small the amount of solar energy absorbed might be.
Researchers have provided two different hypotheses for understanding the impact of solar radiation on earth's atmosphere. The first one says that temperatures are modified in the atmospheric level where earth's weather is formed due to solar radiations when the solar energy is at its highest. The second hypothesis points towards the significance of highly energized solar particles that enter the earth's atmosphere, creating more charged molecules, which in turn modifies cloud formation. This supposedly causes significant climate changes, especially in the weather and temperatures.
It is evident from the study that solar radiations affect the earth's temperature to some extent. Researchers are looking forward to a more detailed study of the solar activities that will help to understand how significant they are in making an impact on earth's global warming and climate changes.
