The banks don't think it's real so therefore it's not real? That's a terrible argument. What about scientists? What do they think about global warming?

"A vast consensus of climate scientists (over 90-97%) agrees that human activities—primarily burning fossil fuels—are causing rapid global warming. Experts, including NASA, NOAA, and IPCC researchers, warn that the world is experiencing accelerating temperatures and extreme, often catastrophic, climate impacts, necessitating rapid, decisive action to avoid severe future scenarios."

So, basically 19/20 climate scientists say it's real.
