An Associated Press article on climate change said, "Some of the ice shelf's disappearance was probably during times when the planet was 36 degrees Fahrenheit ( 2 degrees Celsius) to 37 degrees Fahrenheit (3 degrees Celsius) warmer than it is today." What mistake did the reporter make?

Short Answer

Expert verified
The mistake the reporter made is that they underestimated the conversion from Celsius to Fahrenheit. The correct statement should be that the planet was 35.6°F (2°C) to 37.4°F (3°C) warmer than it is today.

Step by step solution

01

Convert Celsius to Fahrenheit

To convert a temperature from Celsius to Fahrenheit, we can use the following formula: \( F = \frac{9}{5} C + 32 \) Where F is the temperature in Fahrenheit and C is the temperature in Celsius.
02

Calculate 2°C to Fahrenheit

We know that 2°C is the lower limit in the given range. Let's convert it to Fahrenheit using the formula: \( F = \frac{9}{5} (2) + 32 \) \( F = \frac{18}{5} + 32 \) \( F = 3.6 + 32 \) \( F = 35.6 \) So, 2°C is equal to 35.6°F.
03

Calculate 3°C to Fahrenheit

We know that 3°C is the upper limit in the given range, so let's convert it to Fahrenheit using the formula: \( F = \frac{9}{5} (3) + 32 \) \( F = \frac{27}{5} + 32 \) \( F = 5.4 + 32 \) \( F = 37.4 \) So, 3°C is equal to 37.4°F.
04

Identify the Mistake

According to our calculations, a temperature increase of 2°C corresponds to an increase of 35.6°F and a temperature increase of 3°C corresponds to an increase of 37.4°F. However, the reporter stated that the temperature increase ranged from 36°F (2°C) to 37°F (3°C). The mistake the reporter made is that they underestimated the conversion from Celsius to Fahrenheit. The correct statement should be that the planet was 35.6°F (2°C) to 37.4°F (3°C) warmer than it is today.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

Celsius to Fahrenheit Conversion
Understanding the formula for converting temperatures from Celsius to Fahrenheit is crucial for accurate scientific reporting and general knowledge. The formula is as follows:
\begin{align*} F = \frac{9}{5} \times C + 32 \end{align*}
This equation stems from the fact that the Celsius and Fahrenheit temperature scales have different zero points and scale increments. The ratio \( \frac{9}{5} \) represents the ratio of one degree Celsius to Fahrenheit, and the addition of 32 accounts for their different starting points (the freezing point of water is 0°C or 32°F). For those still grappling with this concept, consider visualizing the Fahrenheit scale as 'stretched out' compared to Celsius, with more degrees between the freezing and boiling points of water.

Practical Example

When converting 2°C to Fahrenheit, the equation is applied as follows:
\begin{align*} F = \frac{9}{5} \times (2) + 32 = 35.6°F \end{align*}
The reported 36°F was in fact incorrect, demonstrating the importance of precise calculations when performing temperature conversions.
Understanding Temperature Scales
Temperature scales are essential tools for measuring heat energy. There are several scales used around the world, but the most commonly used are Celsius (°C) and Fahrenheit (°F).
  • The Celsius scale, originally known as 'centigrade', is part of the metric system and is used widely across the globe. It is based on the freezing (0°C) and boiling points (100°C) of water at 1 atmospheric pressure.
  • The Fahrenheit scale is often used in the United States and its territories. Its points of reference are the freezing point of water at 32°F and the boiling point at 212°F, again at 1 atmosphere of pressure.
Subtle as they may seem, these differences in reference points mean that each increment on the Fahrenheit scale is smaller than on the Celsius scale. This logic underlines the process of conversion between the two. Mastery of these concepts guarantees precision when discussing temperature in various scientific disciplines.
Science Reporting Accuracy
The importance of accuracy in science reporting cannot be understated. Any miscalculations or misrepresentations can have profound implications, potentially leading to misunderstanding public opinion or misinforming policy decisions. As seen in the original example, a simple error in converting Celsius to Fahrenheit led to an inaccurate climate change statement.
Scientific accuracy extends beyond mere numbers; it encompasses the correct interpretation and communication of data. Journalists, educators, and scientists have a responsibility to ensure their information is rigorously checked and correctly presented.

Accuracy in Action

When reporting temperature-related data, always cross-check conversions and ensure that the context and scale used are clear to the audience. For students and professionals, practical exercises to convert temperatures, like the one in this example, are more than just academic tasks; they play a pivotal role in developing precision and promoting scientific literacy.

If a thermometer is allowed to come to equilibrium with the air, and a glass of water is not in equilibrium with the air, what will happen to the thermometer reading when it is placed in the water?

In \(1986,\) an enormous iceberg broke away from the Ross Ice Shelf in Antarctica. It was an approximately rectangular prism \(160 \mathrm{km}\) long, \(40.0 \mathrm{km}\) wide, and \(250 \mathrm{m}\) thick. (a) What is the mass of this iceberg, given that the density of ice is \(917 \mathrm{kg} / \mathrm{m}^{3}\) ? (b) How much heat transfer (in joules) is needed to melt it? (c) How many years would it take sunlight alone to melt ice this thick, if the ice absorbs an average of \(100 \mathrm{W} / \mathrm{m}^{2}, 12.00 \mathrm{h}\) per day?

Your house will be empty for a while in cold weather, and you want to save energy and money. Should you turn the thermostat down to the lowest level that will protect the house from damage such as freezing pipes, or leave it at the normal temperature? (If you don't like coming back to a cold house, imagine that a timer controls the heating system so the house will be warm when you get back.) Explain your answer.

In some countries, liquid nitrogen is used on dairy trucks instead of mechanical refrigerators. A 3.00-hour delivery trip requires 200 L of liquid nitrogen, which has a density of \(808 \mathrm{kg} / \mathrm{m}^{3}\). (a) Calculate the heat transfer necessary to evaporate this amount of liquid nitrogen and raise its temperature to \(3.00^{\circ} \mathrm{C}\). (Use \(c_{\mathrm{P}}\) and assume it is constant over the temperature range.) This value is the amount of cooling the liquid nitrogen supplies. (b) What is this heat transfer rate in kilowatt- hours? (c) Compare the amount of cooling obtained from melting an identical mass of \(0-^{\circ} \mathrm{C}\) ice with that from evaporating the liquid nitrogen.

One method of getting a tight fit, say of a metal peg in a hole in a metal block, is to manufacture the peg slightly larger than the hole. The peg is then inserted when at a different temperature than the block. Should the block be hotter or colder than the peg during insertion? Explain your answer.
