Studying the climate crisis | Dangerous dogs | A teacher’s scorn | Learning reluctantly | Whatevs, Megs

The obvious solution to American researchers having grants withdrawn for projects containing the word “climate” (Outcry as Trump withdraws support for research that mentions ‘climate’, 21 February) is to rename climate heating “Trump”. We could be amazed that “Trump makes seas rise”, “Trump makes Greenland a green land again” and “Trump makes summer warmer and longer”. Who would oppose that?

• My friend always said that you should never leave a small child and a dog of any size together as it is equivalent to leaving two toddlers together and giving one of them a pair of sharp scissors (The rise of the cane corso: should this popular status dog be banned in the UK?, 19 February).
