Yes the orbits are changing, that is basic knowledge (or so i thought). Hell precessional wobble affects the climate and that is a roughly 26,000 year cycle, there are so many variables to climate that operate on timelines we can not comprehend. Our impact on the overall climate is miniscule
No source? But so what? We weren't around then and the Sun was cooler. Now we're putting that very same CO2 back into the atmosphere, and the Sun is hotter.
I’ve seen somewhere before that during the dinosaurs they have 5X the amount of CO2 we have today
What point would that be?
As for the op, the guy was making a smart a$$ remark making a point.
He’s mega-trolling this lady into admitting she’s helpless to effect the changing climate.
The Earth rotates about its axis once a day, but it does not do so uniformly. Instead, the rate of rotation varies by up to a millisecond per day. Like a spinning ice skater whose speed of rotation increases as the skater’s arms are brought closer to their body, the speed of the Earth’s rotation will increase if its mass is brought closer to its axis of rotation. Conversely, the speed of the Earth’s rotation will decrease if its mass is moved away from the rotation axis.
Melting land ice, like mountain glaciers and the Greenland and Antarctic ice sheets, will change the Earth’s rotation only if the meltwater flows into the oceans. If the meltwater remains close to its source (by being trapped in a glacier lake, for example), then there is no net movement of mass away from the glacier or ice sheet, and the Earth’s rotation won’t change. But if the meltwater flows into the oceans and is dispersed, then there is a net movement of mass and the Earth’s rotation will change. For example, if the Greenland ice sheet were to completely melt and the meltwater were to completely flow into the oceans, then global sea level would rise by about seven meters (23 feet) and the Earth would rotate more slowly, with the length of the day becoming longer than it is today, by about two milliseconds.
Melting sea ice, such as the Arctic ice cap, does not change sea level because the ice displaces its volume and, hence, does not change the Earth’s rotation.

Aye not a problem. LoL
That is as soon as we can build the likes of a Dyson swam or sphere.
Celestial engineering is somewhat above Humanities current pay grade and then some.
