I want to know the answer to the following question:
How much colder was world in last glacial age?
All the background I'm provided with is that "Noting that the Earth was only 6 °F (3.3 °C) colder during the last glacial period, he noted that the burning of coal and oil "a general warming of the Earth by about one degree Fahrenheit."". Is that enough to answer the question?
Answer: yes
