Which of the following statements about scientists' views of global warming is true? a. nearly all scientists agree that the earth's temperature is rising and that humans are responsible. b. nearly all scientists agree that the earth's temperature is rising, but many disagree about whether humans are responsible. c. nearly all scientists agree that the earth's temperature is rising, but most agree that humans are not responsible. d. there is no consensus among scientists on this issue; they disagree over whether the earth's temperature is rising

a. nearly all scientists agree that the earth's temperature is rising and that humans ARE RESPONSIBLE

Explanation:

Option (B)

Explanation:

Global warming refers to the rise in the global temperature of the earth. It is caused due to various reasons, such as increasing absorption of solar radiation by the earth's surface and the atmosphere, volcanic activities, deforestation, increase in the concentration of greenhouse gases such as CO₂, H₂O, CFC and CH₄ in the atmosphere, burning up of fossil fuels.

The effects of global warming is significant, as it can lead to the rise in the sea level, rise in global temperature, and many more.

Scientists are continuously studying the causes and effects of global warming and confirmed that the temperature of the earth has increased considerably over the last few decades. There are two groups of scientists, where one group agrees that humans are responsible for the rise in global temperature, and some other groups disagree about whether anthropogenic activities are a cause of it or not.

Thus, the correct answer is option (B).
