I want to know the answer to the following question:
A program in Los Angeles believes that with $1 billion, city temperatures could be reduced by approximately how many degrees in Celsius?
All the background I'm provided with is that "The higher temperatures are a result of increased absorption of the Solar light by urban materials such as asphalt and concrete, which have lower albedos and higher heat capacities than those in the natural environment.". Is that enough to answer the question?
Answer: no
