@justadildeau Think of it like having a fever. Every degree makes a big difference. "1.5°C May Not Seem Like Much, But It’s a Really Big Deal. Here’s Why. First, 1.5C is 2.7F. That still might not seem like much, but there are certainly times when a 2.7°F increase would be a cause for concern. For example, if a child had a fever of 101.3°F, 2.7°F above normal, it would certainly be a cause for concern. All sorts of biological processes are affected by temperature, including when leaves open and fruits form, insects hatch, and fish spawn. And because so many of those biological processes are interconnected, the effect of even minute changes in temperature can cascade through an ecosystem.
Continued warming may cause rapid climate changes that cannot be easily reversed for centuries or longer. Examples of such changes include abrupt sea-level rise and slowing or even shutdown of a key part of the ocean’s system for circulating heat. While few studies suggest that these changes are imminent, models and “deep time” climate records both show that somewhere out there, beyond the 1.1°C of warming experienced to date, dangerous tipping points exist. We don’t know exactly where they are, just that further warming makes it more likely we will cross them.
The scientific community has concluded that holding warming below 1.5°C/2.7°F offers the best chance to prevent irrevocable changes to the climate system." National Center for Science Education
