TOPIC: Thesis on Greenhouse Effect and Global Warming Assignment Global warming is related to the greenhouse effect, however, because the greenhouse gases in the atmosphere have been increasing in the last decade, and that means the heat from the sun, radiating back to Earth as the greenhouse effect, is becoming warmer, leading to climate change and disruption of many areas here on Earth. When the Suns energy is at its peak (solar maxima), temperatures in both the lower atmosphere (troposphere) and the upper atmosphere (stratosphere) become warmer.

It takes decades to centuries for Earth to fully react to increases in greenhouse gases. One inevitable consequence of global warming is sea-level rise. The absorbed solar energy heats our planet. In a world with high clouds, a significant amount of energy that would otherwise escape to space is captured in the atmosphere.
