July 21, 2024 was the hottest day ever (updated date)

I am not answering your question because it is a ridiculous one. Nobody is arguing Antarctica is going to melt in 17 years causing the sea level to rise 230 feet. Jesus man, stop digging.

 

Land based Glaciers melting cause sea level rise. Frozen oceans don’t.

The relevance of a melting Arctic is
1. Sea water absorbs more heat vs ice which reflects sunlight.
2. The melting of ice in some arctic areas could cause release of trapped additional greenhouse gases like methane.

 

I'll try one more time. Do you agree or disagree that the sea levels have risen 4 inches in the past 30 years? Or that sea level have risen roughly 8 to 9 inches in the past 150 years? I agree with both of those statements. Do you?

 

seems about right.

America's Sea Level Has Risen 6.5 Inches

 

Wow, you're overwhelming me with your depth of knowledge. I never would have thought about that unless you pointed it out to me.

More cow farts!!

 

No, not frozen cows.

Also the relevance of melting Arctic Ocean is it changes the overall salinity of the nearby oceans.

 

Yep, according to climate.gov, "global mean sea level has risen about 8–9 inches (21–24 centimeters) since 1880."

Yes, the temperature shift in this graph below caused 8 to 9 inches in sea level increase over a 139 year period of time:



So, I'm calling BS on this below. Are you?

"by 2100, Florida could see sea levels rise by up to 6 feet"
Florida's projected sea level rise by 2100 is bad news for sunshine state

 

The Arctic Ocean isn't going to melt.

The bigger concern would be the Greenland glacial melt, as well as additional glacial melt in Antarctica that would occur if temperatures went up as much as some of the whackos are prognosticating. But my guess is that will never happen....or if it does, it will take thousands of years to play out which obviously gives humans time to adapt and by that point, carbon emissions will be a footnote in the history lesson, so you'll have to find a different scapegoat. Or perhaps we will have evolved by then and poke fun at our ancestors who thought carbon emissions were the cause.

 

That looks like a high estimate. It seems unlikely but I have no way of knowing. I think most estimates are between 1-3 feet by 2100.

The melting is accelerating. Once the melting starts, in some cases it doesn’t stop. They have detected some places around Antarctic that has underwater melting streams and once they start they tend not to stop. Estimating at what what that melts or accelerates is highly speculative.

I’m not vested in any particular sea level rise estimate. I have no idea. From my perspective we should be doing whatever we can to slow the pace, and adapting our environment for the likely consequences.

 

The Arctic Ocean has melted to a degree, in the summers. That trend is likely to continue.

I mostly agree with the rest - but the rate of melt is probably a bit of a wildcard. The more melting, the more trapped greenhouse gases are released, and warming could accelerate. We just don’t know.

 

Well, I go back to the most recent 30 years then. The last 30 years, which, as we can see from the data above had the strongest temperature anomalies of the past century and a half. We had 4 inches of sea level rise in the past 30 years. Not seeing a lot of evidence there of a rapidly accelerating melt. Or at least evidence of a consequential melt. Global temperature increase has been essentially flat for the past decade.

 

There was 8-9 inches in 140 years and 4 inches in the last 30 years. 3 inches in last 20 years.

America's Sea Level Has Risen 6.5 Inches.

So that is 5 inches in 110 years, and 4 in the last 30, 3 in last 20. Seems like acceleration to me.

No idea how you come up with temperature is flat.

 

If you were part of a religion that was known for routinely touting certain dates or years in the not so distant future, of when apocalyptic events would occur and then those dates and years came and went with nothing happening, my hope is that you would take some time to reflect on who you're listening to. That's what I see with the climate change panic. Lots of snake oil salesmen selling fear, while profiting immensely.

 

Apparently the rise is different in different places

America's Sea Level Has Risen 6.5 Inches.

 

You can cherry pick snippets from an Al Gore movie, but overall what has been predicted re climate change is largely coming true. Temperatures continue to rise. Sea level is rising, at an accelerating rate. More drought. More coastal flooding.

Like I showed earlier Exxon Scientists got it right 40 years ago.

 

I don't think you quite understand what accelerated melt entails. Global temperature anomalies have roughly stayed the same the past 10 years. How do you explain the colder than usual anomalies and cooling trend that was occurring in the mid-1970's, long after industrialization and CO2 emissions kicked into high gear?

 

I am using global averages.

 

He said that by 2013 the north polar ice cap would completely melt. That's not cherry picking. That is making a false prediction that simply never occurred or even came close.

 

past 8 years highest temps on record. How is temperature flat?

As to 70s it appears that some speculate from 40s to 70s the high rate of sulfate pollution caused cooling. But there was no scientific consensus we were in a long term cooling trend. That was just media hype.

 

whatever I don’t give a shit about one specific prediction by Al Gore. The last 8 years have been the hottest on record, worldwide ice is melting and sea level is rising, consistent with models made 40 years ago.
