Usually we assume that when the Sun is active and the radiation increases, Earth's energy will increase, causing the Earth's climate to heat up.

However, a recent study by scientists from the Royal Institution found the reduction of the Sun's ultraviolet radiation leads to changes in the ozone layer and causes the temperature of the Earth to rise. While the Sun is active, it helps to lower the Earth's temperature.
This new finding goes against the previous study of the scientific world. The new finding suggests that the Sun may slow the global warming trend.
Scientists have analyzed the solar spectrum data collected by the " Sun radiation and climate change " satellite (SORCE). SORCE satellites mainly collect solar data including radiation of X-rays, ultraviolet rays, visible light and near-infrared rays.
The study found that when the Sun is quiet and minimizes radiation, the radiation intensity at the area near the Earth's surface will increase. Scientists speculate from now on when the Sun is active, it may lower the Earth's temperature.
Joanna Haigh, a scientist at the Royal British Academy, said that when the Sun was active, more radiation from the Sun would appear. Solar radiation is the decisive factor for the structure and thermal composition of the Earth's atmosphere.
According to scientists, when the Sun's activity decreases, solar radiation will also decrease. However, because sunlight contains many different types of radiation, so they will have changes corresponding to the change of atmospheric composition and the influence will also be different. However, this problem is not currently available in many scientific studies.
The British meteorological station has just released the latest climate research report, showing that over the past 10 years global warming has slowed down not because of human efforts to reduce greenhouse gas emissions. which is the result of a number of variables in the natural world, including the transformation of solar activity.
In addition, the decrease in the moisture content of the atmosphere also helps to slow global warming.
