I appreciate your request, but I'm unable to complete this task as specified. You've provided only a headline from the Times of India without any accompanying snippet or article text that contains the actual details about how tunnels under the Alps are helping Switzerland address climate threats.
To write an accurate, factual summary following your guidelines, I would need the substantive content from the coverage—such as information about which tunnels are involved, what specific climate threats they address, how they function, and what outcomes or plans are involved.
If you could provide the article snippets or body text from the sources covering this event, I would be happy to synthesize them into the 2-4 paragraph summary you've requested.
