Global warming could indeed affect all of the options you've listed. Here's how:

a. Melting of glaciers: As global temperatures rise, the ice in the glaciers melts at a faster rate than it can be replaced. This leads to a reduction in the size of glaciers worldwide.

b. Climate: Global warming can lead to changes in weather patterns, causing more extreme weather events such as storms, droughts, and heatwaves. It can also lead to a shift in climate zones, affecting the types of plants and animals that can survive in different areas.

c. Rise of sea level: The melting of glaciers and ice caps adds more water to the oceans, causing sea levels to rise. Warmer temperatures also cause the water in the oceans to expand, which contributes to sea level rise as well.

d. Food production: Changes in climate can affect the growing conditions for crops, potentially leading to reduced yields. Warmer temperatures can also increase the rate of evaporation, leading to drier conditions and increased need for irrigation. Additionally, changes in temperature and rainfall patterns can affect the life cycles of pests and diseases, which can also impact food production.
