Question

An Excerpt from: “Cyclones and Climate Change: Connecting the Dots”

By Agence France-Presse, adapted by the Newsela staff

Scientists say the don’t know everything about how climate change affects hurricanes. But, what they do know is enough to worry them.

Burning fossil fuels creates greenhouse gasses. Fossil fuels are natural fuels like oil, gas, and wood. The gasses, in turn, cause the Earth’s temperature to rise. It is called climate change. Scientists say the magnifying effect of sea level rise, warming oceans, and hotter air is simple science. All are results of climate change. They also have seen faster shifts in storms’ power, such as Hurricane Harvey in Texas. A sudden change turned Harvey from a Category 2 hurricane to a Category 5, on a scale of 5.

Detailed Data on Hurricanes is Missing

What’s missing is a detailed record of past hurricanes. Climate scientists need decades of measurements. This would help them determine how much people have played a part in global warming.

“It is awfully difficult to see climate change in historical data so far because hurricanes are fairly rare,” Kerry Emanuel said. He is a professor at the Massachusetts Institute of Technology.

Experts agree that climate change could make tropical storms more powerful. The storms are known around the world as cyclones, hurricanes, and typhoons. But, scientists are puzzled, for now, by a lack of information.

Just because the information is not clear yet doesn’t mean that the changes haven’t been occurring, said James Kossin. He is a scientist at the U.S. National Oceanic and Atmospheric Administration’s Center for Weather and Climate in Madison, Wisconsin. Kossin figured out that cyclones have been drifting toward the north and south poles. Other hurricane experts call it the clearest sign so far that climate change has already had an effect. Hurricanes form where the ocean is warm. This is usually near the equator. But, climate change is heating up other parts of the ocean. This is why cyclones are drifting toward areas in the north and south poles that weren’t warm before.

Answer: A conclusion or logical guess about a text that is based on evidence and known facts.

Part 2: Use the RAD method to identify and explain evidence from the passage that supports the inference that, in the future, it will be easier to understand the impact climate change has on hurricanes.

R (Restate the question):
The question asks for evidence that supports the inference that understanding the impact of climate change on hurricanes will become easier in the future.

A (Answer the question):
In the future, it will be easier to understand the impact climate change has on hurricanes due to the potential for improved data collection and a better understanding of historical patterns.

D (Provide evidence from the passage):
The passage states, “What’s missing is a detailed record of past hurricanes. Climate scientists need decades of measurements. This would help them determine how much people have played a part in global warming.” Additionally, it mentions that “just because the information is not clear yet doesn’t mean that changes haven’t been occurring.” This implies that as more data is collected over time, scientists will be able to identify links between climate change and hurricane patterns more definitively.

Explanation:
The lack of detailed historical data on hurricanes is currently a barrier to understanding the full impact of climate change. However, as more data is gathered and analyzed over time, scientists will make connections that allow for a clearer understanding of how climate change influences hurricane intensity and behavior. This future accumulation of knowledge will make it easier for scientists to assess and understand the effects of climate change on hurricanes, as indicated in the information provided in the passage.
