I have seen in every movement that while people share the goal, they do not share the strategy. The strategy often involve trade offs and cultural values that is separated from the common goal, and the stronger people feel about the goal the more convinced they are about their own chosen strategy. The most bitter fights tend to be between people who strongly share the same goals.

Preparing for a hotter world is nice, but what I am hoping is that nations (and the green movement) will realize that all strategies need to be deployed and it doesn't matter if one strategy feels like it is being counter productive to the values of an other. Some people can focus on replacing meat with vegetarian options, other on ecological meat, some on reducing factory farming in favor of local small scale production, and some on low carbon meat like shell fish. Let some build nuclear power plants, other renewable energy and battery. Focus on building bike infrastructure, rail system and electrify all parts of the transport system.
