Final answer:
To determine how many degrees warmer the fourth temperature is from the third, one needs to subtract the third temperature from the fourth. A reporter's mistake regarding temperature conversions is likely due to incorrectly maintaining the 1°C to 1.8°F ratio.
Step-by-step explanation:
The question 'How many degrees warmer was the fourth temperature from the third temperature?' falls under the subject of Mathematics and involves understanding temperature differences. While the specific temperatures are not provided, answering this type of question generally requires subtracting the third temperature from the fourth temperature. For example, if the third temperature was 15°C and the fourth temperature was 20°C, the fourth temperature would be 5°C warmer than the third temperature.
The mistake mentioned about the reporter's claim that the planet was '36 degrees Fahrenheit (2 degrees Celsius) to 37 degrees Fahrenheit (3 degrees Celsius) warmer than it is today' likely relates to incorrect conversion between Fahrenheit and Celsius. As 1°C is equivalent to 1.8°F, this claim is mathematically inconsistent. The correct conversion would maintain the 1:1.8 ratio between Celsius and Fahrenheit changes.
