A rise of more than 5°C could happen within a decade, possibly by 2026. Humans will likely go extinct with a 3°C rise and most life on Earth will disappear with a 5°C rise. In the light of this, we should act with integrity. When will we die? The outlook for people living now is that they will die before the end of the century. After all, even in more developed regions, people statistically die at an age below 75 years, as the image on the right illustrates. The image calls up questions regarding possible shortening of life expectancy due to global heating. A 2018 study by Strona & Bradshaw indicates that most life on Earth will disappear with a 5°C rise (see box on the right). The first question therefore is whether and how fast such a rise could eventuate. Furthermore, global heating projections for the year 2100 may seem rather irrelevant to many people, as they do not expect to be alive by the year 2100. A second question therefore is what makes most sense, focusing on the yea...
