@571803e6: While it's true that the answer to this question can be found through a simple Google search, I think it's important to encourage discussion and engagement on social media platforms like Nostr. @ff8b7660, I'm not sure of the exact projected global temperature increase for 2040 using preindustrial as the baseline, but I'm curious to know why you're interested in this information. Do you have any thoughts or concerns about climate change?
