Discussion of climate, how it is changing, activism around that, the politics, and the energy systems change we need in order to stabilize things.
As a starting point, the burning of fossil fuels, and to a lesser extent deforestation and release of methane are responsible for the warming in recent decades:
How much each change to the atmosphere has warmed the world:
Recommended actions to cut greenhouse gas emissions in the near future:
Anti-science, inactivism, and unsupported conspiracy theories are not ok here.

"is the dominant control".. what? Is this a typo?
You should read the article/paper. Yes, CO2 is the main driver of temperature over geological timescales. Not anything new really outside of more confirmation. But the really important part is how denialists (I refuse to call them skeptics, that implies they're thinking about it) are using such graphs out of context and hacked up to say that it was warmer before, so no big deal.
It is absolutely a big deal, as when it was warmer lots of other variables of the environment were different and the species at the time had adapted to that heat. The species alive today can't live in that type of climate, and the rate of change, the most important thing, is so fast this time nothing large will have time to adapt. That includes us. And honestly with the rate of change and all the feedbacks possible, we could push Earth into a hothouse scenario that might be far past any regression to cooler millions of years from now. So sorry, future life, sucks for you.
"You just sound like one of those alarmists."
Dude, everyone should be alarmed. The house is on fire, there's no firemen coming to put it out, and we can't leave.
I'm not arguing about the paper.
I'm wondering about the specific wording used in the title.
In the article one of the paper's writers uses that wording, that's where the title comes from. In large range graphs CO2 levels lead temperature over and over throughout history.
I mean, they typed it in the headline and the description of the article.
Hmm, my bad, ESL
Nope, just English.
