Detailed explanation-1: -There is a direct relationship between climate change and sea level rise. As our climate warms, sea level rises mainly because of thermal expansion (when water warms up, it expands) and melting of snow, glaciers and ice caps (which increases the volume of ocean water).
Detailed explanation-2: -As greenhouse gas emissions blanket the Earth, they trap the sun’s heat. This leads to global warming and climate change. The world is now warming faster than at any point in recorded history. Warmer temperatures over time are changing weather patterns and disrupting the usual balance of nature.
Detailed explanation-3: -The terms “global warming” and “climate change” are sometimes used interchangeably, but “global warming” is only one aspect of climate change. “Global warming” refers to the long-term warming of the planet.
Detailed explanation-4: -What Is Climate Change? Climate change is a long-term change in the average weather patterns that have come to define Earth’s local, regional and global climates. These changes have a broad range of observed effects that are synonymous with the term.
