Explanation

All of the listed impacts are associated with global warming:

1) Rise in sea level: Global warming leads to the melting of polar ice caps and glaciers, contributing to a rise in sea levels.

2) Melting of glaciers: Increased temperatures cause glaciers to melt, contributing to sea level rise and altering ecosystems.

3) Spread of diseases: Warmer temperatures can expand the range of many pathogens and vectors, potentially increasing the spread of diseases.

4) Bleaching of coral reefs: Elevated sea temperatures cause coral bleaching, where corals expel their symbiotic algae, leading to a loss of color and vitality.
