Do we need to be preparing for Arctic cruising strategies because of Global Cooling

Some other facts

1) CO2 is a greenhouse gas. That has been known for about 200 years.

2) Using carbon isotope analysis, the 40% increase in CO2 since the start of the industrial revolution can be linked directly to the burning of fossil fuels, a human activity.

3) The last time CO2 levels were 400 ppm was 3-5 million years ago.

4) Using ice core CO2 levels fluctuated between 180 and 300 ppm for at least 800,000 years prior to the industrial revolution.

5) Natural cycles worked well in maintaining a "Goldilocks" world in which human beings evolved and their food crops evolved and were domesticated.


Your last sentence is a policy concern that should use science as a basis for its direction.

Munich Re keeps tabs on such data. Notice that geological events have remained somewhat static. Weather and climatological related events are on the increase.

6) Despite never ending research focusing mostly on the potentially detrimental effects of greenhouse gas related climate warming, no actual detrimental effects unequivocally attributable solely to global warming have yet occurred despite almost twenty years having passed since the cries of alarm began.

In fact the second link (Arctic News) says the opposite.

So I thought I would check out

https://www.google.ca/webhp?sourceid...obal%20warming

and found this first link to Tom Moriarty who is an AGW skeptic.

Read the rest for the math involved.

Ha ha. It's Moriarty again my dear Watson.

Can someone please explain why sea levels are dropping in the USA north east?

I read this account of a NW passage voyage by a junk rigged sailboat (2012) and enjoyed it. Seems cold up there.

Giordano Bruno has risen from dead, and is alive and well on the blog of a radio weatherman.

Will check that out.

Are the seas actually dropping or is the land RISING?

Maybe the entire continent will CAPSIZE due to too many people. LOL

Two cherry locations using a cherry picked time frame.

I have a suspicion that Bruno is the new pseudonym for Tony Heller aka Steve Goddard. He has tried this previously.

Allow me to add a cherry to that bunch.

The mean sea level trend is 6.62 millimeters/year with a 95% confidence
interval of +/- 0.69 mm/yr based on monthly mean sea level data from
1957 to 2011 which is equivalent to a change of 2.17 feet in 100 years.

And to add the extra whipped cream...





Has sea level not been progressively rising at any time within the current interglacial?

According to your graph the rate of sea level rise is increasing. I think that is a big concern to some scientists.
