Rising Sea Levels And Global Warming


Tiberius

Recommended Posts

The worsening of tidal flooding in American coastal communities is largely a consequence of greenhouse gases from human activity, and the problem will grow far worse in coming decades, scientists reported Monday.

 

Those emissions, primarily from the burning of fossil fuels, are causing the ocean to rise at the fastest rate since at least the founding of ancient Rome, the scientists said. They added that in the absence of human emissions, the ocean surface would be rising less rapidly and might even be falling.

The increasingly routine tidal flooding is making life miserable in places like Miami Beach; Charleston, S.C.; and Norfolk, Va., even on sunny days.

Though these types of floods often produce only a foot or two of standing saltwater, they are straining life in many towns by killing lawns and trees, blocking neighborhood streets and clogging storm drains, polluting supplies of freshwater and sometimes stranding entire island communitiesfor hours by overtopping the roads that tie them to the mainland.

And here you have the NYT giving you the idiot's guide to tough questions about global warming cooling climate change. It's like it was written by and for gatorman.

2. How much trouble are we in?
For future generations, big trouble.
3. Is there anything I can do?
Fly less, drive less, waste less.

Funny thing is that, if you read the research the article is based on, it's actually all over the map. The author of that article cherry-picks worst cases and glosses over data that's not "worst-case" enough with ambiguous blanket statements (which is the actual definition of "obfuscating," by the way.)

 

When you look at the research, and see results that say the ocean's rise has accelerated since 1979 by one micron per year per year, plus or minus half a micron, according to satellite measure that began in 1979, whereas other measurements show a half-micron per year accelleration, you should be asking three things:

 

1) Satellites can measure with a half-micron's accuracy?

2) Given that it starts in 1979, and is poorly supported by other data sets, Is that one-micron difference real or an artifact of satellite measurement?

3) When you measure something one way as 1 +/- 0.5 units, and another way as 0.5 units...is it reasonable to then base predictions on that something having a value of 6? (Which is what the accelleration would have to be for the "consensus" value of 3.4 feet of sea level rise by 2100 to be accurate.)

This seems believable to me:

And the original article was also convincing
