Generate a series of (instruction, response) pairs that are similar in context and structure to the example provided below. Each pair should consist of a concise instruction followed by an appropriate, detailed response. The instruction should pose a clear task or question, while the response should provide a comprehensive answer or solution that could be understood by someone with a basic understanding of the subject.

Example pair: 
Instruction: Summarize this excerpt in three sentences:

The year 2022 was one of the most stress-inducing for consumer air travelers in recent memory. A surge in travel demand after airlines slashed resources during the pandemic caught carriers flat footed. Unable to adequately staff flights, they nevertheless continued to sell record-breaking numbers of tickets, resulting in more than one in five flights being delayed, according to the U.S. Bureau of Transportation Statistics — the highest rate of delays since 2014.

By Memorial Day last year, airfares were soaring, and flight cancellations started to mount. The situation worsened over the summer, as bouts of disruptive weather left passengers stranded and forced Transportation Secretary Pete Buttigieg to call a meeting with airline CEOs.

While autumn was mostly free of disruptions, the year ended with a winter storm that brought airline travel to a standstill, especially at Southwest Airlines.
Response: During 2022, excessive demand for flights and the recent lack of resources to supply them resulted in nightmarish conditions for the industry, especially for workers in understaffed environments. Despite the lacking conditions, airlines still sold massive amounts of tickets, causing numerous delays that outweighed those of several years prior. Throughout the year, complications in weather and other factors caused the form of travel to be more expensive, less reliable, and in the wintertime to come to a complete halt in some cases.

Your task is to generate more pairs that maintain this level of clarity and detail. The topic is Summarization. Write a long text of instruction by yourself, then summarize the given instruction in a response. Ensure that the responses are informative and accurate, suitable for an educational context. 

Store the generated pairs in valid JSON format, with each pair as an object within an array. Each object should have two key-value pairs: "instruction" and "response". For instance: 

{"contents": [{"instruction": "text", "response": "text"}, {"instruction": "text", "response": "text"}, ...]} 

Remember to maintain consistency in the format and ensure the generated pairs are diverse and cover a broad range of subjects. You must return the response in the asked format and you must not add any additional text in your response.

Summarize the following excerpt in three sentences: Climate change has become one of the most pressing issues of our time, with rising temperatures, melting ice caps, and more frequent extreme weather events. Efforts to mitigate its effects include transitioning to renewable energy sources, enhancing carbon capture technologies, and promoting sustainable practices. Despite these measures, global collaboration and significant policy changes are needed for meaningful progress.
