Portable rechargeable led floodlight related knowledge

The solar portable rechargeable led floodlight uses solar energy to save energy, does not produce carbon dioxide, and does not accelerate the greenhouse effect. There is a certain relationship between the concentration of CO2 (carbon dioxide) stored in the Antarctic ice sheet and the time. According to the measurement, the concentration of CO2 at the end of the 18th century is about 280ppm (pm-luLL), which exceeded 300pm in the 20th century, from 1960. It began to increase dramatically, and has entered the 21st century by more than 350ppma. The value published by the Japan Meteorological Agency in 2010 shows that the concentration has reached 390ppm.

The average temperature curve of the Earth in the same age was affected by various factors. In the past 100 years, the global temperature has increased by 0.74 °C. From the above, the trend of temperature changes is very similar to the change of CO2 concentration.

Why does the increase in CO concentration increase the temperature of the Earth's environment? This is because the CO2 in the air absorbs the infrared rays radiated from the earth into the universe, and the earth seems to be a huge plastic greenhouse. In English, it is called "green house effect", translated as "greenhouse effect."
