If it turns out that sea ice is disappearing as measured over a period of years, maybe a decade or three, it would be indicative of global warming.
Global warming will also cause the land based ice around the world to melt, particularly in Greenland and the Antarctic. That would cause sea level
rise.
Therefore, sea ice coverage IS something to consider when addressing sea level rise.

sprinklers
polar bears are hardly disappearing. seems when they restricted hunting them their population increased! who'd thought it?
and the arctic ice isn't disappearing either. ever hear the phrase figures can lie and liars can figure? well NASA et al used to measure sea ice in
30% concentrations. they changed that about 10yrs ago to 15% so as to include slushy ice close to shore. this year the 15% concentration is low yet
the 30% concentrations is the highest it's been in 15yrs! but you don't hear about that do you?
I too have upgraded to industrial grade to do my part in our manmade drought here in SoCal

BTW, go visit Glacier National Park to see the remaining glaciers, while you still can.
"A century ago, this sweep of mountains on the Canadian border boasted some 150 ice sheets, many of them scores of feet thick, plastered across
summits and tucked into rocky fissures high above parabolic valleys. Today, perhaps 25 survive."

Greenland/Antarctica
[ particularly in Greenland and the Antarctic.] Hmmm Well how do you explain WW11 era planes that crashed landed in Greenland and are now under 260ft
of ice? Inquiring minds want to know.
Recent Antarctic satellite laser altimetry paper by NASA's Jay Zwally showed Antarctica to be gaining surface mass (more ice and snow).
Go figure a circular firing squad of scientists.

Lead Author Jay Zwally: "I Know Some Of The Climate Deniers Will Jump On This," But "It Should Not Take Away From The Concern About Climate Warming."
In an interview with Nature, the study's lead author, glaciologist Jay Zwally, warned that "climate deniers" would wrongly tout the study as proof
that "we don't have to worry [about global warming] as some people have been making out"
"Zwally stated in the NASA press release that the study is "essentially in agreement with other studies" showing that land ice in West Antarctica is
severely decreasing, but that the "main disagreement is for East Antarctica and the interior of West Antarctica." He also noted that over the next
couple of decades, ice loss in West Antarctica will likely outweigh the snowfall increase in East Antarctica, and that sea level rise over past
decades must be coming from somewhere else."

The glacier response, here we go again
Glacier National parks glaciers advanced during the Little Ice Age which ended appx 1850. The threshold for maintaining the glaciers was probably
exceeded during warming between 1850 and the 1920s (Selkowitz et al. 2002). Not a lot of SUV's running around Baja back then!

Zwally had been sitting on that paper for at least 4yrs. You gotta love the backpedaling. Truth hurts

Frank, the subject is sea level. I am asking for proof (that anyone, not just "scientists" can see).
Your photo showed the sea level well below the damage.
The cause was erosion (storm rain runoff of storm high tide waves) or even an earthquake.
Can anyone post a photo of an object, that was not moved, that was above the sea 50 years ago but in the sea today due to a higher normal sea level.
I can... and it is in Baja just above sea level today as it was in the 1950s.
Alfonsina's concrete slab the restaurant is sitting on is also the same height above the sea as it was when I was there in 1965.
The beach homes in Mission Beach, Del Mar, and other places along the ocean, built in the 1940s and 50s, are still above the sea.
How do you explain that?

According to the United States Geological Survey:
"In Glacier National Park (GNP), MT some effects of global climate change are strikingly clear. Glacier recession is underway, and many glaciers have
already disappeared. The retreat of these small alpine glaciers reflects changes in recent climate as glaciers respond to altered temperature and
precipitation. It has been estimated that there were approximately 150 glaciers present in 1850, and most glaciers were still present in 1910 when the
park was established. In 2010, we consider there to be only 25 glaciers larger than 25 acres remaining in GNP."

Selkowitz et al. 2002 is referenced.

How do you explain that? |
How do you explain that you will only believe pictures and you cannot accept measurements?
As a historian, how did you manage to read and understand historical accounts of baja without pictures? Given your posts, it seems that you believe
data without a photo is garbage.

According to the United States Geological Survey:
Here I'll go sloooooow for you. By 1920 it was already to late.What happened since then is irrelevant. They were doomed 96yrs ago long before Nomads
were spewing Co2 all over Baja with their fossil fuel based toys! Leave Baja to us deniers so we can still get some uncrowded surf. My carbon
footprint is HUGE

Measurements
The problem with tide gauge data in Mexico is that the few they have stopped functioning/reporting data to NOAA the most recent being 1990. All were
short term stations only operating since roughly 1950. Cabo's shows very little rise 1.68mm but with huge error bars of +/- 3.62mm! So statistically
no sea level rise. But again it's a spotty gauge that no longer reports.

So what caused the sea to rise 28 centuries ago??? I think if we could just nuke the whales, the sea level would fall!!!

You know we all might be to blame in some small way. The fish we take from the sea, the ones we keep to eat, were previously a part of the total sea
volume so we make the sea level go down. Since you're all convinced the sea is rising at a dangerous rate, we should all catch and keep more and
bigger fish --- and we'd better get to it. I'll do my part as soon as this old body can move about and the fish show up. That's a pledge. Color me
green on the matter. Will I get some kind of honorary scientific degree or somethin'?

I'm pretty sure that the recycled pacifico I deposit while fishing more than makes up for the volume of fish I take.
