According to many peer-reviewed studies, over 97% of climate scientists agree that human activity is extremely likely to be the cause of global climate change. An examination of scientific papers that didn’t agree that humans cause climate change found serious flaws and bias in their research. But a Purdue University survey found that 47% of climatologists challenge the idea that humans are primarily responsible for climate change and instead believe that climate change is caused by an equal combination of humans and the environment. Gases released into the atmosphere trap heat and cause the planet to warm through a process called the greenhouse effect. Over the 20th century, as the concentrations of CO2, CH4, and NO2 increased in the atmosphere due to human activity, the earth warmed by approximately 1.4°F. The specific type of CO2 that is increasing in earth’s atmosphere can be directly connected to human activity.
We can tell that CO2 produced by humans burning fossil fuels such as oil and coal is different from naturally occurring CO2 by looking at the specific isotopic ratio. The amount of solar energy received by the earth goes up and down in cycles, but overall, there is no net change since the 1950s. There has, however, been a big increase in global temperatures that is too large to attribute to the sun. The World Meteorological Organization said the current acceleration in the rate of ocean acidification ""appears unprecedented"" over the last 300 million years. Human-caused global warming is changing weather systems and making heat waves and droughts more intense and more frequent. In a process known as a positive feedback loop, more warming causes more humidity which causes even more warming.
Q. Which of the following could be inferred from the passage about the CO2?
  • a)
    CO2 is the most harmful gas that is there, that affects the earth’s climate change.
  • b)
    There are different types of CO2 gases that affect the earth’s atmosphere differently.
  • c)
    About 50% of the CO2 released by the burning of fossil fuels and other human activities has already been re-absorbed by the earth’s carbon sinks.
  • d)
    26% of human-caused CO2 emissions were absorbed specifically by the world’s oceans.
Correct answer is option 'B'. Can you explain this answer?

When the author tells that there is a different isotopic ratio if CO2 produced by humans and CO2 produced by the burning of fossil fuels, it becomes clear that there are different categories of CO2. Option (c), (d) and (a) talks about the information which is not present in the passage.

Inference About CO2 from the Passage
The correct inference regarding CO2 from the passage is option 'B': "There are different types of CO2 gases that affect the earth’s atmosphere differently." Here's a detailed explanation:
Types of CO2
- The passage discusses how CO2 produced from human activities, particularly by burning fossil fuels, has a distinct isotopic signature compared to naturally occurring CO2.
- This difference in isotopic ratios indicates that not all CO2 is the same; rather, it can be categorized based on its source.
Impact on Climate Change
- The passage emphasizes how the specific type of CO2 linked to human activities is a significant contributor to the greenhouse effect, which leads to global warming.
- By acknowledging the different types of CO2, it implies that their origins (natural vs. anthropogenic) impact the atmosphere differently, particularly in terms of their contribution to climate change.
Exclusion of Other Options
- Option 'A': The passage does not explicitly state that CO2 is the most harmful gas; it focuses on its role in climate change.
- Option 'C' and 'D': There is no information provided in the passage regarding the percentage of CO2 reabsorbed by carbon sinks or absorbed by oceans.
Conclusion
- Thus, option 'B' is the only inference that can be drawn based on the information provided in the passage, highlighting the significance of understanding the different types of CO2 and their effects on the atmosphere.
