It hasn't come up the mountain to the Tavern yet. But the US weather folk at NOAA tell us it won't be long.
Personally, I look out and see very little practical, obvious evidence.
High tide at Fort Denison in Sydney Harbour. You can see that if the sea is rising, it's not rising very much. More evidence that the alarmist figures put out by the climate bigots are a crock. Al Gore prophecies rises of several metres.
You can see that the sea level has been plateaued since 1950 -- exactly the time that the climate bigots say global warming began. So NONE of the rise was due to global warming. The small amount of global warming we appear to have had in recent decades did not shift the sea level one iota. Fun!
When the water reaches the window, then you can worry. Meanwhile much will be written, many statistics made up and poured over, and vast amounts of GW grants will be given to over-excited scientists. Many scary, imaginative illustrations will be made.
At NOAA, and elsewhere.
Believe it or not !!Is sea level rising?Yes, sea level is rising at an increasing rate.
What's the difference between global and local sea level?
Just the facts, ma'am.
Global sea level trends and relative sea level trends are different measurements. Just as the surface of the Earth is not flat, the surface of the ocean is also not flat—in other words, the sea surface is not changing at the same rate globally.
Not to mention the weight of cities !! Oz, for instance is very slowly tipping over with all the building going on on the East side and barely any on the west to even it out !! And there's all the concrete wellie jobs happening.Sea level rise at specific locations may be more or less than the global average due to many local factors: subsidence, upstream flood control, erosion, regional ocean currents, variations in land height, and whether the land is still rebounding from the compressive weight of Ice Age glaciers.
Hmmmm. And photos taken every 50 years or so are just so cheap and easy. Much better to pour vast sums into satellites.Sea level is primarily measured using tide stations and satellite laser altimeters. Tide stations around the globe tell us what is happening at a local level—the height of the water as measured along the coast relative to a specific point on land.
Aaaarghhh. Where are your water-wings?Satellite measurements provide us with the average height of the entire ocean. Taken together, these tools tell us how our ocean sea levels are changing over time.Global sea level has been rising over the past century, and the rate has increased in recent decades. In 2014, global sea level was 2.6 inches above the 1993 average—the highest annual average in the satellite record (1993-present). Sea level continues to rise at a rate of about one-eighth of an inch per year.
Higher sea levels mean that deadly and destructive storm surges push farther inland than they once did, which also means more frequent nuisance flooding. Disruptive and expensive, nuisance flooding is estimated to be from 300 percent to 900 percent more frequent within U.S. coastal communities than it was just 50 years ago.
The two major causes of global sea level rise are thermal expansion caused by warming of the ocean (since water expands as it warms) and increased melting of land-based ice, such as glaciers and ice sheets. The oceans are absorbing more than 90 percent of the increased atmospheric heat associated with emissions from human activity.With continued ocean and atmospheric warming, sea levels will likely rise for many centuries at rates higher than that of the current century. In the United States, almost 40 percent of the population lives in relatively high-population-density coastal areas, where sea level plays a role in flooding, shoreline erosion, and hazards from storms. Globally, eight of the world's 10 largest cities are near a coast, according to the U.N. Atlas of the Oceans.
Sea level rise at specific locations may be more or less than the global average due to local factors such as land subsidence from natural processes and withdrawal of groundwater and fossil fuels, changes in regional ocean currents, and whether the land is still rebounding from the compressive weight of Ice Age glaciers.
It really is a lot of crock.In urban settings, rising seas threaten infrastructure necessary for local jobs and regional industries. Roads, bridges, subways, water supplies, oil and gas wells, power plants, sewage treatment plants, landfills—virtually all human infrastructure—is at risk from sea level rise.

The unemployed are not dragooned to the sea shore and given planks and saws and hammers.
Safe bet is that we are safe and we need more concrete wellie jobs.
What do you think?
Me? I shall have a pint.
