What happened to levels of carbon dioxide from 2002 to 20014? What effect does this have on global warming? 3. Global Temperature. Click on the interactive link for global temperature. Is there any net increase or decrease to global temperature from 1884 to 1979? What is happening to global temperature from 1990 to 2015 Use the following website: http://climate.nasa.gow/fag/ to answer the questions below 1. Contrast global warming and climate change. 2. What percentage of scientists agree that climate change is caused by humans? 144

Explanation / Answer

The broad changes in the perennial ice from 1979 to 2017 are as follows:

Question 1:

Answer: 1. There is periodic change in the size of the ice (area of the ice fluctuates )

2. This periodicity is sought of constant between 1979 to 1996.

3. After 1996 though the periodicity of increase and decrease still exist but an overall decrease in the area of the perennial ice can be seen.

Question 2:

Answer: If the sea level rose by 2m , City if New Orleans will be under water. While if the sea level rose by 6m, City of Miami and City if New Orleans will be under water.

Question 3:

Answer:

From the interactive it can be seen that there is a steady rise in the C02 emissions. Major changes can be observed in the year 2008, 2010, 2012, 2013 and so on. Increase in C02 emissions does have a effect on the global temperature. Since C02 is a greenhouse Gas, it traps the heat within the earth's atmosphere thereby increasing global temperatures.

Question 4:

Answer:

Broadly there has been an increase in the temperature from 1884 to 2017. There are fluctuations of temperature with temperature decreasing and rising in 1884-1990 while between 1990-2015 there is a very minor fluctuation and overall rapid increase in temperature.

Part 2.

1.

Global warming refers to the long term warming of the planet while climate change encompases global warming, but refers to the broader range of changes that are happening to our planet.

2. 97 % of the scientists agree that climate change is happening.
