Sea Level History​

Is Climate Feedback even right about their broad claims? No. At best, the group raises issues which are debatable. That calls for debate, not censorship.

-----------------------------------------------------------​

David Legates, professor of geography at the University of Delaware:​

“water has been rising for approximately 20,000 years, and probably will continue.”

Climate Feedback’s Claim:

“[That’s] imprecise and misleading … it implies sea levels have continued rising since then …”

Reality:

Sea levels HAVE continued rising. The fact-checkers’ own sea level graphs show that, even if the increase over the last 6,000 was slower.
Here’s Climate Feedback’s source for the last 20,000 years:

Climate Feedback also asserts that “in the last 6,000 years, global sea level was stable … until an increase in the rate of sea-level rise 100–150 years ago.”
But their own source shows it rose about 10 feet over the last 6,000 years. [p.15301 of this PNAS academic source, the source that Climate Feedback’s source cites for its data, per its footnote 60.]

Climate Feedback’s False Claim:

“[Stossel] implies … current sea level rise is just a continuation of past natural fluctuations …”

Reality:

We don’t imply that. We said nothing about that. We simply said that humans have successfully adapted to rising sea levels. It’s happened for millennia.
Legates’ 20,000 feet comment comes as a segue to “we can adapt, like Holland has.” We never say that sea level will keep rising at the same rate.
Data do show that sea level rose steadily over the last 150 years, at a very constant rate. From Climate.gov:

Yet this has hardly been a crisis for humanity; living standards skyrocketed during the same period.

Climate Feedback’s Claim:

“The causes of the global warming event that explains sea level rise at the end of the last ice age 20,000 years ago are different from those that explain sea level rise now.”

Reality:

Our video doesn’t say or imply anything to the contrary.

My video also questioned the claim that hurricanes have gotten stronger.

“Misleads viewers,” said Climate Feedback.
But on this topic, reviewer Brown said my video is accurate! “That’s wrong that you were criticized for saying that,” he says. “The IPCC (doesn’t) claim that (hurricanes)… droughts… floods are increasing.”
Later Brown emailed us, saying that “the problem is omission of contextual information rather than ‘facts’ being ‘wrong.'”

Oh. Climate Feedback’s “fact-check” wasn’t about actual facts.

Climate Feedback’s “fact-checks” do sometimes criticize alarmism, too, if it’s truly absurd, like New York Magazine’s cover story, “Uninhabitable Earth.”
But as I told Brown, “There were three times as many fact-checks on skeptics as on alarmists.”

“That’s wrong,” he responded. “They should be fact-checking the alarmist side just as much.”
They should. But they don’t.
Vincent and Climate Feedback doesn’t want debate. They want to silence debate.
Facebook lets them.

Climate Feedback’s Misleading Claim:

Climate Feedback then cites Patrick Brown, assistant professor at San Jose State University, who argues: “There are sufficient fossil fuels available to completely melt the Greenland and Antarctica ice sheets and raise global sea levels approximately 60 meters or 200 feet[18]. This would represent an astronomical cost …”

Reality:

Obviously, if sea level rose 200 feet, that would be astronomically costly. But the UN IPCC does not consider that likely at all.
Brown subsequently told us that his 200-feet increase scenario is plausible over a period of a thousand years.
This is far outside the range of what the UN IPCC projects, with good reason. Imagine how different technology will be in a thousand years.
1,000 years from now, humans will probably have machines that suck carbon out of the air.
A thousand years ago, the height of technology was the crossbow.
It’s more reasonable to consider projections for a century, which Brown himself cites: a rise of about 1-3 feet.
How does “adaptation” do as a strategy in that case?
Statistician and environmentalist Bjorn Lomborg cites a 2018 study in the journal Nature Climate Change that finds (his summary):
The total cost of coastal protection and of all remaining flood damage through the rest of the century, even in the absolutely worst-case scenario, will cost the United States just 0.037 percent of its GDP, and possibly five times less.

That’s a small price to pay, compared to reorganizing the entire economy to try to eliminate emissions.
