Climate progress is elusive for everybody. It’s way too big for humans. We can’t speed up or slow the rotation of the earth, we can’t change the tilt of Earth’s axis, we can’t do anything to move the earth nearer to or farther from the sun. We have no ability at all to change the amount of energy coming from the sun. The best we can do is try to manage tiny tiny amounts of carbon dioxide and methane so minuscule that we can’t even measure them accurately. And these carbon compounds have an exceedingly tenuous effect on the amount of sunlight reaching the ground or heat leaving the atmosphere, since water vapor is the most influential component of air as it relates to climate.
Yes, they are tiny amounts. The issue is natural and manmade variation from a variety of causes. That makes the numbers jump around and appear to be inaccurate. But measurements themselves are fairly accurate, within 2.5% plus or minus from the actual value.
