True, although historic changes have been much less dramatic, i.e. 2 degree increase over 5,000 years not in 5 years.
To your point, "so what", well why do we manage elk and deer, why not just shoot as many as we feel like, why manage predators? We do these things to mitigate dramatic change from year to year, to maintain consistency so that it's easier for us to plan and live our lives. Sure humans will not go extinct in the next 100 years due to climate change, but you may lose your home to sea level rise or floods and crops may be decimated by droughts, snow, floods, etc. Those of us with the least means are going to be those most effected.
The conversation get's muddled by the massive amount of partisanship going on right now, this hasn't been and shouldn't be a my team your team conversation.
(Don't make me post that damn Nixon state of the union for a 5th time, republicans were the party of sportsmen and championed environmental protections not wanting to f-up the woods is not a goal owned by the Democrats)
The demand for energy goes up every year, there is plenty of market share for wind, solar, O&G, and coal. There is nothing wrong with adding new jobs to our economy.
The population of the world is also increasing, we voted and Ben Lamb is not going to get the infinity stones, therefore we need to conserve and protect our wild places which in my mind means thinking critically every time we build new energy infrastructure on public lands.
