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: Can you sum up all the following text in one short sentence for me?

Climate change ‘winners’ and ‘losers’
Megan Cimino and other scientists predict that in decades to come, Adélies could disappear from the western Antarctic Peninsula and nearby islands.

“We’ve already seen one … Adélie colony that went extinct. A few of our other colonies on different islands are very close to extinction,” Cimino said. “We’ll see how long they sort of hold out.”

But in other parts of Antarctica, like Ross Island, thousands of miles away from Palmer Station, researchers have seen Adélies thrive.

Ross Island is closer to the pole and colder than the Antarctic Peninsula — too cold for the gentoo penguins. Here, Adélie populations have largely grown or remained stable over the last two decades, said Grant Ballard, chief science officer at Point Blue Conservation Science, a nonprofit research organization that advocates for conservation.

Ballard describes himself as a “die-hard optimist” — and he thinks warming temperatures in Antarctica could create not just problems, but also new opportunities for penguins.

“There’s going to be places where the ecosystem will thrive and … new life will be emerging,” Ballard said.

Steven Emslie, a biology professor at the University of North Carolina, Wilmington, has found ancient penguin mummies on a coastline near where Ballard does his research. Emslie thinks cooling temperatures hundreds of years ago may have made the place uninhabitable for Adélies — but that might not be the case anymore.
Response: Adélies could disappear from some areas due to climate change, but survive elsewhere in places that used to be too cold for them.

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.

What is the main cause of global warming?
user
The primary cause of global warming is the increase in greenhouse gases, such as carbon dioxide and methane, due to human activities like burning fossil fuels and deforestation.
