Global warming is driven by human-induced greenhouse gas emissions, leading to climate change, and significant temperature increase. Burning fossil fuels contributes significantly to greenhouse gas concentrations, trapping heat energy and affecting weather patterns.

Explanation:

Global warming refers to the increase in the average temperature of the Earth's atmosphere due to elevated greenhouse gas concentrations, heightening the greenhouse effect. Climate change includes both global warming driven by human-induced emissions of greenhouse gases and resulting large-scale shifts in weather patterns.

The observed century-scale rise in the average temperature of the Earth's climate system is termed global warming. Human activities such as burning fossil fuels have led to an enhanced greenhouse effect, causing this phenomenon to accelerate significantly since the middle of the 20th century.

Anthropogenic greenhouse gas emissions from activities like burning fossil fuels are a major contributor to global warming. These gases trap heat energy in the atmosphere, leading to changes in weather patterns and extreme events like hurricanes.
