Sea level

I love settled science

Actually, the whole point about science is that it should never be settled.  Everything should be tested, proved, checked, and advanced as new discoveries are made.

It is not up to politicians like Al Gore or anyone else to declare and decree that “the science is settled”.

The science is of the global climate is most definitely not settled regardless of what the media might parrot. Exciting new things are discovered all the time and many of these have a bearing on global ocean current circulation patterns, cloud formation, glaciers and all manner of stuff.

The latest one, as published in Nature, and reported by New Atlas, is that the Mariana Trench is drinking the ocean and doing so faster than they previously knew.

Might this affect sea-level rise?  No, of course not. The science is settled, remember. Quote. Read more »

So you are worried about sea level rises due to climate change?

Well don’t be

Carbon dioxide, climate change, disaster, SEA LEVELS WILL RISE!

You can see all kinds of sea level rise predictions for the 21st century, with over-wrought images of houses and buildings under water.  One of the favorite predictions of the hand wringers is “1.8 meters” of sea level rise for the 21st century.  A major purveyor of this lurid climate-porn prediction is Stefan Rahmstorf (see here, here, and here).

Consider the following points

  • 75% of atmospheric anthropogenic CO2 arrived after 1950.
  • There has been no obvious acceleration in sea level rise rates since 1950 as seen from tide gauges.
  • Extrapolating tide gauge time series to 2100 would give about 15cm of sea level rise between 200o and 2100.
  • Projections of 1, 1.8 or 2 meters of sea level rise between 2000 and 2100 would require extraordinary rise rate accelerations.   Read more »

Sea level. Who knew it wasn’t simple?

Climate Change bullshit from the Herald

Isaac Davidson has an article in the Herald today about allegedly rising sea levels, in particular the unique scientific anomaly where water levels are rising faster in the Marshall Islands than anywhere else on the planet…yes I’m not kidding they really claim that.

The Marshall Islands have a population of 55,000 spread over 180sq km of coral atolls and islands.

* 2m above sea level on average.

* Sea levels have risen 7mm a year since 1993, compared with a global average of 0.4mm.

* Sea levels are expected to increase by up to 15cm by 2030.

Really? …Does Isaac know anything about fluid dynamics? How can a sea level rise faster in the Marshall Islands…than say Fiji, or Samoa?

Quite apart from the fact that this is impossible…go on I dare you to try and raise the water level in your pool in just one spot…say…at the shallow end…go on try it…add in more water at the shallow end…it should according to Isaac Davidson raise the water level just where you added the water…and increase it more than the rest of the pool.

But hey, let’s not let facts get in the way of a good story from the “decent journalists, trained and skilled” at the Herald.  Read more »
