He noted that ongoing measurements of surface temperature, ice, and sea level provide “consistent signals that the planet is warming…. We need to keep watching the data. We’re confronted with a long-term issue that isn’t going to go away. We need to keep the focus on this issue.”

For the last 8,000 years, temperatures have been falling, while sea level has been rising. Rising sea level does not indicate that the planet is warming. Rather, it indicates that we are no longer in an ice age.
The world’s largest reservoir of sea ice (Antarctica) has been increasing for as long as records have been kept. Cicerone calls this a “consistent signal” that the planet is warming.

“Rather, it indicates that we are no longer in an ice ice.”
ice ice?????????????
That all depends on your definition of ICE AGE! Is the a certain percentage of global surface being covered year round that defines an Ice Age. From what I have read the globe is experiencing an Ice Age with periods of minimum glaciation like the period we live in.
Mr. Davis I believe you are correct. A technical definition is that we are no longer in an ice age when all the ice is gone. That will not happen for thousands of years.
From what I have read, we’re actually in the middle of a mice age. And of a cockroach age.
