According to all of the world’s scientists, we only have until 2030 to stop climate change. Otherwise, it will be irreversible and people will begin to die due to the subsequent famines, droughts, rising sea levels, and extreme weather as early as 2040
. The key is that what is going to happen post-2030 very much effects the current population. Most people under 50 will live past 2040, and could suffer lethal or catastrophic impacts on their lives due to climate change.
This means that fighting climate change is as important and life-sustaining an issue as education, healthcare, or stopping hunger. Neglecting climate change entirely and allowing it to continue on unimpeded will mean that we’ll have to spend more money down the line to deal with its inevitable effects. Doing nothing about climate change is a short-sighted solution.
