We are playing Russian roulette with the future of mankind, the climate change deniers are prepared to go against a lot of science.
I don't care if a few nuclear plants blow up for the sake of the planet not choking to death.
200 years of spewing untold crap into in to the atmosphere and into the oceans cant be good, and its only getting worse.
I believe we are past the tipping point and we can only hope their is life elsewhere in this universe.

Yeah. Nuclear fission is not the cleanest way of making electricity, it is just MUCH cleaner and safer than mining and burning coal.

Why some keep denying the warming I don’t know, apart from fear, fear of change, fear action on AGW might affect them a bit. I dunno. Anybody who has kids or grandkids I would have thought would want them to have a decent world to make their way in, but pure selfishness seems to override that. Don’t understand that myself.

Let us have a look at the abstract of the article Lees quoted:

Quote:

Abstract

The Atlantic Coast of North America is increasingly affected by flooding associated with tropical and extratropical storms, exacerbated by the combined effects of accelerated sea-level rise and land subsidence. The region includes the collapsing forebulge of the Laurentide Ice Sheet. High-quality records of late Holocene relative sea-level (RSL) rise are now available, allowing separation of long-term glacial isostatic adjustment-induced displacement from modern vertical displacement measured by GPS. We compare geological records of late Holocene RSL to present-day vertical rates from GPS. For many coastal areas there is no significant difference between these independent data. Exceptions occur in areas of recent excessive groundwater extraction, between Virginia (38°N) and South Carolina (32.5°N). The present-day subsidence rates in these areas are approximately double the long-term geologic rates, which has important implications for flood mitigation. Tide gauge records, therefore, should be used with caution for studying sea-level rise in this region.

So the sea levels are rising and the rise is accelerating and there is natural and manmade subsidence. I am sure Lees just accidentally forgot to mention that the study noted that sea levels are rising at an accelerating rate.

This is the sort of rubbish your alarmist claptrap leads to Monk...
Well done. Cheesy

Oh dear. Little difference, EXCEPT in areas of excessive groundwater extraction.

Excessive groundwater extraction leads to - subsidence. Which in turn gives false SLR figures. Caution - Tide gauge records should be used with caution.

So they can calculate isostatic rebound. Makes you wonder how they determined SLR?
