THE article headlined “Call for ‘unprecedented action’ to tackle warming” (Echo, Oct 9) was significant for what it does not mention, as much as what it does, so I will comment on three aspects.

Rising seas: Parts of the Greenland ice-cap are melting (geothermally) from below. Also the tidal range near (and under) the biggest Antarctic ice-shelves can at times be an astonishing six metres. Thus, occasional ice-loss is to be expected, with no link to human activity.

Extreme weather: Presumably this includes hurricanes, but re-examination of data from 1850 indicates Atlantic hurricane activity is cyclical, and not increasing. Human CO2 emissions show no such circularity, hence no link. It would appear that referencing these storms is now off-limits for the proponents of Anthropogenic Global Warming.

Malaria: This disease was endemic in Britain for centuries, and the anopheles mosquito has been native to parts of chilly northern Europe since pre-history. Russia was badly hit in the 1920s, with 18 m infected. In Archangel, close to the Arctic Circle, 10,000 died from the most deadly strain, plasmodium falciparum.

The “threat” of infection linked to warming exists only in computer models. I would suggest we take note of what happens in reality, and get a grip.
