The amount of clouds is one thing scientists look at to determine whether or not global warming can occur due to human activity. The current anthropogenic changes that are occurring increase the enhancement of low clouds. Low clouds produce a cooling effect.
High clouds are the types of clouds that produce a warming effect.
Increased Greenhouse Gases are less of a problem than one would think. Greenhouse Gases are essential for life on planet Earth. They maintain an ideal temperature for humans, animal, and plant life to live. The main problem area where CO2 is dispersed is due to mainly the burning of fossil fuels and deforestation. Since many plants are hibernating during the wintertime, there is a bigger problem during this time of year.
