> IMHO it is just ridiculous to attribute famines to a 1 degree temperature rise, while at the same time ignoring the fact that due to population growth the available land per capita has decreased dramatically within the last few decades. These are two different problems that both need solving, and I'm sure some people in Africa are trying to tackle the population growth problem. If you're on HN right now, I'm sure you are more concerned with the temperature rise problem (by the way, 1 degree? We already passed that).

When did we pass 1 degree (Celsius)?

  Technically, we didn't pass it completely (0.8C). https://climate.nasa.gov/vital-signs/global-temperature/ https://climate.nasa.gov/vital-signs/global-temperature/ 2016 reached 1C of warming anomaly relative to 1951-1980 average, but was exceptionally hot. But there are enough greenhouse gases in the atmosphere and feedback loops in action so that, even if all human activity stopped right now, the 1C bar will be easily toppled, and depending on prediction models, the 1.5C is probably already unavoidable as well.

    Maybe, but that wasn't my point in the original post. The famines that are taking place today are attributed to the temperature rise so far, and that is clearly below 1 degree. Just for comparison, in Bangladesh the population has quadrupled since the 1950s.

      Bangladesh is not suffering of famines? Africa is suffering of famines, and the land use is far from saturated. Furthermore, most of the planet except Africa has a fertility rate below 2.5 already (Bangladesh at 2.4). The biggest reason for the population growth is due to the current population NOT dying of famines, diseases, etc. like they used to, and dying of old age instead. There is nothing to do to tackle the population growth, you would have to literally kill people.
