FUN FACT: Did you know the word "Biome" is like an international passport for plants and animals? Yes, it tells us where they live! 🌍

Biomes in the spotlight!

Biomes are moving in response to climate change; specifically, they're shifting from the equator towards the poles, and up mountainsides too.🌳🏔️

 

Real-world example: Imagine how as you climb up a mountain, the vegetation changes from forests at the bottom to alpine meadows higher up. That's an altitudinal shift.🌲➡️🌼

Species & biodiversity

As biomes shift, the types of species in an ecosystem will change. Fast climate change leaves little time for animals to adapt. Some can move, but others that can't may go extinct.

 

Real-world example: Think about polar bears. As Arctic ice melts, their hunting grounds shrink, endangering their survival.❄️🐻

Impact of climate change on forests

Forests in the US, which absorb 13% of the country's greenhouse gas emissions, are threatened by wildfires, insect infestations, and drought, all exacerbated by climate change.

 

Real-world example: In 2015, the largest area of American forest since 1960 was consumed by wildfires, costing over $2 billion. Fire seasons have gotten longer due to hotter temperatures, rising from 50 to 125 days since 1970.🔥
