Sea levels are rising

[Cyclone 10]

As a scientist he is at least familiar with how to gather data, how to analyse data and how to read papers (and look for flaws in their methodology).

Effectively both disciplines are modelling complex problems using computers though, they build up models and then compare them to real world results, validating the models.

His main objection seems to be that the climate models we use at the moment are terrible, basically unvalidated, the predictions they do make are constantly way off base.

The climate definitely seems to be undergoing changes, but our models don't accurately model it, so they're probably of little use in predicting the change or indeed how we might alter it...

Can you explain what relevance his expertise in vibrations in rocket engines has to commenting on climate science?

 

You wouldn't ask an electrical engineering Phd to design you a bridge. Why would to ask a mechanical engineering Phd for analysis of the climate?

A bit more relevance than the so called expertise of the so called climate scientists and doesn't cost the earth.

 

I would if the so called bridge builder was selling me a pup, you'd probably pay up and fall to the bottom of a ravine.

What qualifies Al Gore?

I’m not convinced that climate change is altogether mankind’s fault, but we do have professor Hawkins saying that we need to find a new planet within a single life time. I think he believes the end of the earth is nearer than we think.

 

He tends to blame climate change, asteroid strikes, epidemic and the earth being overpopulated. So if his forecast is correct, does not look good for the next generation.

 

I have no idea what to believe.

He has lived a very unusually long life for someone with the condition he has.

Not really sure what he is.

What qualifies Al Gore?

 

Al Gore was selected as the Democratic nominee for the 2000 presidential election and he is a rich successful person; he also received the Nobel Peace Prize. He also went to Harvard.

In his senior year, he took a class with oceanographer and global warming theorist Roger Revelle, who sparked Gore's interest in global warming and other environmental issues. Gore earned an A on his thesis, "The Impact of Television on the Conduct of the Presidency, 1947–1969", and graduated with an A.B. cum laude in June 1969.

The scientists say that we need to reduce CO2 emissions to the extent that temperature rise can be kept to less than 2 degrees Celsius, ideally lower - surely you are aware of this

 

Well yes.. but C02 is just one of the problems though isn't it. Apparently CFC's was also one which causes problems with the ozone layer which also contributes to warming. Fluctuations in the suns rays reaching us is also another factor and so is methane. Greenhouse gasses are not just C02.

The ozone hole does not contribute to global warming.

True but ozone is also classed as a greenhouse gas.

The two major contributors to sea-level rise are:

 

1) Glacial meltwater being released at a faster rate than being replenished. This applies to around 80% of glaciers.

 

 

2) Water expands as temperature rises. The Volumetric Temp Coefficient of water at 10 C aproximately = 0.0001

 

The world's ocean is approximately 1,335,000,000,000 cubic metres with an average depth of 3700 metres

 

Assume the ocean is contained in a tank 19000 * 19000 * 3700, at 10 Celsius.

 

If the water temperature is increased by 1 degree Celsius. The new volume would be 1,335,833,570,000

 

The new depth would = new volume / (19000 * 19000) = 3700.37 metres, an increase of 370 millimetres

 

There are a lot of assumptions in the above but it does serve to indicate the basics of temperature

induced sea-level rise.

 

 

Another factor is Isostatic Rebound. Land masses are depressed by the large weights of ice, when the ice

melts away the land mass rises giving an apparant local sea-level fall.

True but ozone is also classed as a greenhouse gas.

 

CFCs didn't destroy ground level ozone though, they destroyed the ozone layer, which is not the same as ozone at lower altitudes (chemically it is, but not with regards to trapping heat).

The ozone layer doesn't contribute to heating.

Then you're pretty poor at googling.

The sea is not rising period - it's called a lie.

 

Has anyone noticed in their life the sea has risen?

 

Of course not!

 

Do you really think Everton would build a new stadium on the banks of the Mersey if this hoax was real?

 

Wake up.
