Sort of like an extremely really stupid argument, Tomato Panda.
Not even going to bother breaking it all down, but one of the most important points would be that 30 years is a lot in terms of technological and scientific advancements. Can’t really state nothing can be done, as long as people are trying then the proper advancements will be made in fields that benefit the solution to climate change/global warming.
If your solution to a problem is get it over with because eventually it will happen (maybe), I guess you should end your life now. (not telling you to kill yourself but that’s basically the level of argument you made)
