Global Warming:

…..is the increase in the average measured temperature of the Earth's near-surface air and oceans since the mid-20th century.

Hypothesis

If our living habits do not change it is projected that there will be a continuation of conditions leading to Global Warming.

I learned that climate change is any long-I learned that climate change is any long-term significant change in the average term significant change in the average weather thatweather that a given region experiences.a given region experiences.

Climate changes reflect variations within the Earth's atmosphere, processes in other parts of the Earth such as oceans and ice caps, and the effects of human activity. The external factors that can shape climate are often called climate forcing and include such processes as variations in solar radiation, the Earth's orbit, and greenhouse gas concentrations.
