Night and Day?

By 2100, the tropics could be 'dangerously hot' for half the year (https://www.theguardian.com/environment/2022/aug/25/half-of-year-will-be-dangerously-hot-in-tropics-by-2100-research-shows). If people are very proactive and limit 'greenhouse gas' emissions keeping within the parameters agreed in Paris (i.e. limiting global heating to 1.5 degrees Centigrade above pre-Industrial levels), the outcome might be just about tolerable. If, however, emissions continue to rise, a study confirms that there will be huge consequences for people, primarily in the global South. The South doesn't contributing as much to the climate emergency as the North. The South's regions would, however, become unliveable for half the year. There would be many deaths, serious problems with food production and massively increased pressures to migrate. The difference between the two outcomes would be comparable to the distinction between night and day. There are, however, few current indications that limiting planetary heating to 1.5 degrees Centigrade above pre-Industrial levels, will be achieved. This would inevitably generate massive global tensions.
