No sea-level falling going on. Sea level is rising at an accelerating rate for CO2 reasons. That's the data.

To argue against that not being our fossil fuel emissions (which are measurably increasing still) is an argument with the basic laws of physics, not opinion.

Regarding the Roy Spencer quote. He published that on his blog, not within a peer-reviewed science journal. When he publishes a peer-reviewed paper ... then let's talk.

For Ref: Mr Spencer is not exactly a reliable credible source - https://www.desmog.com/roy-spencer/

Of course sea level has risen since the last ice age. The ice melted.

Why is well understood.

There are other bodies in the solar system that bump us in and out of ice ages because they alter our orbit. What is going on now is not that ... it really is us.
