Ice-Melt versus Land-Ice Melt-Assignment for Climate Change Lectures

Purpose: To determine which form (or both) of Ice-melt contributes to sea-level rise.

Instruction: PART I-Sea-Ice Demo -Place a glass half filled with water on your table. Add Ice and record the water level on your glass with a sharpie marker. Wait for the ice to melt. Did the water level in the glass change? Is the water level still at the level of the sharpie marking? Why? What are the implications for sea-level rise with melting of sea-ice? Will it increase sea-level rise? Why?

PART II – Land-Ice Demo: Place a glass half filled with water on your table. Record the water level on your glass with a sharpie marker. Add ice and wait for the ice to melt. Did the water level in the glass change? Why? What are the implications for sea-level rise with melting of Land-ice? Will it increase sea-level rise? Why?

Expert Solution

Part 1: in the experiment to check sea ice demo. The water level does not change

Part 2: in the experiment to check the land ice demo. The water level rises comparatively very high.

Now it's necessary to understand whether sea ice melt or land ice melt casues the sea level to rise. Both the warning about melting is concerning to the environment. But the melting of ice sheets on the land contribute more to the rising sea level which is supported by the above experiment. Land ice which contains glaciers, ice sheets is found in Antarctica and Greenland. The blocks of ice in the land are melting and this water is flowing rapidly into the oceans. This increases the volume of water. Which means that it increases or rises the sea well considerably. Whereas this is not the case for sea ice melt. The impact is less as it is already floating in the ocean. Which doesn't not rise the sea level. When the sea level rises rapidly, the implications being a small increase in sea level rise has harmful effects on coastal habitat farther inland. It causses destructive erosion, wetland flooding, agricultural soil contamination by salt, loss of habitat etc. Hence control climate changes to reduce the rising sea level is the need of the hour.

One of the impacts of climate change is an alteration of rainfall patterns with both an increase in large rainfall events and an increase in drought already beginning to show up in the climate record of many different areas of the globe. Currently researchers are working on creating strains of plants that will resist drought and are focused on both plant anatomy and on plant physiology. Think about adaptations that will aid plants faced with drought to help answer the...

Coffee and tea are substitutes, and production of both goods is sensitive to climate change. Coffee production is negatively affected by drought in the major coffee-producing countries (especially Brazil and Vietnam). Tea production is negatively affected by extreme rainfall events in tea-producing countries (especially China and India).We observe that the equilibrium price of tea has risen and the equilibrium quantity of coffee has risen. What could be responsible for this pattern –a drought in Brazil, or an extreme rainfall season...

Australia’s bushfires in 2019 reignite its debate about climate change. In this assignment, you will discuss the public policies on greenhouse gas emissions, an important contributing factor to climate change. 1. Many observers believe that the levels of greenhouse gas emissions in our economy are too high. a. If society wants to reduce overall emission by a certain amount, why is it efficient to have different amounts of reduction at different firms? b. Economics usually prefer corrective taxes over regulations...
