To determine how much sea temperatures have increased every decade since the 20th century, we can refer to historical climate data analysis conducted by scientists and climatologists. Comprehensive studies and reports, such as those from the Intergovernmental Panel on Climate Change (IPCC), provide us with valuable insights into the temperature trends observed over long periods.
After reviewing the scientific literature and reports on sea temperature changes:
- Historically, scientific data indicates that sea surface temperatures have increased at an average rate of approximately 0.14 degrees Fahrenheit per decade since the beginning of the 20th century.
Thus, the correct answer is:
0.14 Degrees Fahrenheit
