I want to know the answer to the following question:
What years were Oklahoma's hottest summers?
All the background I'm provided with is that "Severe drought is common in the hottest summers, such as those of 1934, 1954, 1980 and 2011, all of which featured weeks on end of virtual rainlessness and high temperatures well over 100 °F (38 °C).". Is that enough to answer the question?
Answer: yes
