"If we want to know how much humans contribute to climate change it is critical to first determine the natural forces from the sun"

Climate changes and the environment are currently of top international concern. Satellites will become increasingly important for the surveillance of the Earth's environment since they will be able to furnish uniform information of large areas. Satellites measure changes in polar ice extent and the amount of ozone and other gases in the Earth's atmosphere. They measure changes in sea level, the amount of water vapor in the atmosphere, cloud accumulation and changes in vegetation. Last but not least, it is important to keep an eye on changes in solar activity where the amount of radiation of light and particles toward Earth vary over time. Historically, the sun has caused many climate changes on Earth and much points to it also having contributed to climate changes during the last 150 years. If we want to know how much humans contribute to climate change it is critical to first determine the natural forces from the sun.
