Hey Capt ~

How did Dr Nat do last evening with her presentation?

Close Second

Nice review today!

By Capt. Paul (Eclogite) on Wednesday, January 26, 2011 - 08:14 am:

Hey jbuck; thanks for asking. J
She did awesome last night!!! From what I was told, it was the largest attendance they have had in over 3 years. The talk ran a bit over an hour, but no one left. Unfortunitely for us, because it did run over, we didn't get out until 10 last night and then had to drive home, get to bed, and back up at 4:30 this morning; ugh.....

Thumbs UP for Dr. Nat! :)

Capt Paul, what was Dr. Nat's topic? About global warming or related to it? Sure wish I was in the
Houston area to take in those lectures.
Does Dr Nat believe that the earth's orbit is perfect and no variations that might cause climate change? Something had to have happened in the past to cause ice ages and then the recoveries. Sort of like a cycle. Is the earth on a one way path to eventually becoming a dead planet?

By Capt. Paul (Eclogite) on Wednesday, January 26, 2011 - 12:53 pm:

Her topic last night was "A Tour of Scotland; Geology, Archeology, History, and Pretty Pictures". A discussion of climate change is best suited for the Global Warming thread in the Various Topics page.

If she decides to check the PastyCam today, I'll let her answer that!! ;-)

Maybe you two could send us a few "pretty pictures" soon. I'd love to travel again to Ireland and get some more pics when not in a hurry.

Happy 174th Birthday, Michigan.

By Hollidays (Hollybranches) on Wednesday, January 26, 2011 - 05:06 pm:

No snow today, temps were in the high 30s. Could this possibly be global warming?

By Dr. Nat (Drnat) on Wednesday, January 26, 2011 - 08:08 pm:

Tom, there's many different things that interact to cause changes in Earth's climate. One of the things is, indeed, changes in earth’s orbit. These are known as Milankovitch cycles, named for the scientist who postulated that these variations in the orbit had an impact on climate. The earth’s orbit changes in three ways: eccentricity, obliquity, and precession. Eccentricity is the change from a circular to an elliptical orbit. The obliquity is the angle of the tilt of earth’s axis. It varies between about 22 and 24.5 degrees. The precession, also called the precession of the equinoxes, is the wobble of earth’s axis. Together, these three things vary and can cause changes in the climate.
The earth is not heading towards becoming a “dead planet” any time soon. Someday, however, our sun will die, and so will our planet. But this won’t happen for a few billion years, so I wouldn’t lose any sleep over it.

Thank you to everyone for asking about my lecture. I appreciate the kind thoughts.
