According to the majority of scientists, which of the following occurrences is most responsible for recent increases in global temperatures?
a. volcanic and earthquake activity
b. an increase in radiation released by the sun
c. changes in the earth's orbit
d. an increase in greenhouse gases in the atmosphere

The correct answer is D. An increase in greenhouse gases in the atmosphere

Explanation:

In the last decades, especially in the last 50 years, global temperature has dramatically increased, which leads to changes in climate and has environmental effects, this phenomenon is known as global warming. According to most scientist global warming occurred in previous prehistoric periods, but this time the changes and effects are greater and occur more rapidly.

Additionally, scientists have determined this can be explained due to human activities such as manufacturing that had released greenhouse gases to the atmosphere and this stops heat from the sun going out into space which increases the temperature on Earth. Thus, the occurrence that is most responsible for the increase in global temperature is an increase in greenhouse gases in the atmosphere.
