Variance of the sunset

For a number of years I have kept track of a different phenomenon here in Western Washington. Taking hand held compass reading from the exact same spot in my yard and sited westerly against the same peaks of the Olympic mountains, I have noticed a 4 degree change in the orientation of magnetic north in a Southerly direction! This would indicate a rotational shift or magnetic shift of the planet, coinciding with your noting a northerly variance in the orientation of the sun at sunset.


Can you elaborate please? I’ve been getting closer to my ground and trying to learn more

Very Interesting

I found your article to be very interesting, and I would like to follow what you see, as you go. Do you have a website?

Sunset Positions

The weather patterns are changing rapidly and everyone around the world recognizes this change. I've kept track where the sun has set on 21 June, 21 September, 21 December and 21 March. These 4 positions of the sunset I've noted on a low mountain ridge approximately 5 miles west of my house in northwest Montana over the past four years.

Curious again

I’ve read all your posts. I’m just seeking more. I want to know all of the things.

fires, global warming

I am sorry that the news is not truthful about a lot of things. I have a long time class mate that fights fires all over the west. Last year 16 of the fires in California was caused by PG&E bad maintenance. After consulting with a foreman that works for Parr electric out of Texas repairing and replacing high power transmission lines. I found the above to be true, Yes we have had less rain than in years past, but it does not give our power companies and out of control (CONTROLED) forest service burns the right to kill and destroy our personal property and forests. We complain about the timbers being cut down and our wild life not having a place to live. Wake up people. The forest fire not only displace our animal population, but also destroys it. My fire fighting friend has told me stories of animals running across the fire roads on fire. We need responsible people to step up and do something about it instead of being lied to about the facts. Than blaming everyone and thing except themselves where the responsibility lies.

SoCal North

I just moved from San Diego to Eugene a few months ago, only to find the region is turning into Southern California North.

Hoq many more years of this can we take before the rivers run dry and the hydro plants fail?

Forest Fires

...and proper forestry management.

This is getting really scary, such little rain!!

The Farmer's Almanac has been close most years, but this year it's the roll of the dice....Here in Brookings we usually get a lot of rain, but this year its horrible...Great weather but its not normal for this time of year, what is going to happen next spring and summer when everything is really dry?? We already had a scary 190,000 acre fire 2 years ago that came 5 miles from town, my heart goes out to all those people in Paradise CA who lost their homes and lives....Time to pray for rain folks!!
