1.The figure above describes \"Radiative Forcings\" and the relative magnitudes

Question

1.The figure above describes "Radiative Forcings" and the relative magnitudes that these compounds act as radiative forcings.

A radiative forcing is:

A measure of how much the sun's energy changes because these compounds exist in the sun's atmosphere.

A measure of energy trapped in Earth's atmosphere due to these compounds

A measure of how much each compound exists in the atmosphere.

d A measure of how radioactive a compound is.

2. The conclusion that the IPCC makes using the above diagram is that:

Anthropogenic activities are causing radiative forcings that are warming the Earth with high confidence.

Anthropogenic activities are causing radiative forcings that are warming the Earth with low confidence.

There is too much uncertainty in the total anthropogenic relative forcings to make any conclusions about warming.

Anthropogenic activities are not causing radiative forcings that cause Earth's warming.

3. True or false: Carbon dioxide is a major constituent of our atmosphere (it makes up more than 1% of the atmosphere)

a.

A measure of how much the sun's energy changes because these compounds exist in the sun's atmosphere.

b

A measure of energy trapped in Earth's atmosphere due to these compounds

c

3. True or false: Carbon dioxide is a major constituent of our atmosphere (it makes up more than 1% of the atmosphere)

Explanation / Answer

1.the answer is a,........ radiative forcing is the measurement of energy changes occurring due to addition of green house gases

2.the answer is a, IPCC had stated it with confidence

3.false...the percentage of carbondioxide is 0.0392%
