Explanation:

Combating climate change is challenging because it is expensive in the short term and involves political issues. While some aspects of climate change can be mitigated (not impossible to reverse as some actions can slow or halt certain changes), and it does require technology (but the key multi - faceted challenge is the cost and political will). Also, climate change is well - supported by scientific evidence.
