Assertion: In the past 30-40 years global average land temperatures have increased about twice as fast as global average ocean temperatures.
Reason: Oceans have a large heat capacity and lose more heat by evaporation.

1. Both assertion and reason are true and the reason is the correct explanation of the assertion.
2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false

Assertion: Temperatures have increased about twice as fast in the Arctic as in the mid-latitudes, a phenomenon known as “Arctic amplification.”
Reason: The loss of sea ice is one of the most important reasons for this.

2. Both assertion and reason are true but the reason is not the correct explanation of the assertion.
3. Assertion is true but reason is false.
4. Both assertion and reason are false
