Sandpoint, Idaho from 100 million years in the past, to presents, and 100 million years in the future will have a very unique climate change. Plate tectonics and continental drift will have an enormous effect on the climatology of Sandpoint.

100 million years in the past the earth looked much different than it does today.  The plates were close together and there were large bodies of water in the middle of North America.  Luckily for the past 500 million years there have been tons of ice core dating for detecting the carbon dioxide levels of earth.  Most models show that the Polar Regions were up to 72 degrees F warmer; “100 million years ago, the Earth's temperature was 20° - 40° Celsius warmer (or 36 ° - 72 ° F) in the polar regions, although only a few degrees warmer around the equator. Evidence suggests that during warm Cretaceous periods, levels of atmospheric carbon dioxide was higher” (http://www.ncdc.noaa.gov/paleo/ctl/cliscibeyond.html).  The sea levels will be the largest meso climate control for Sandpoint. 

Sandpoint was roughly located at 45 N, 105 W.  Typically this would mean that it would be affected by the polar jet streams and possibly Maritime Polar and Continental Polar.  However, since the Polar Regions were much warmer it probably meant that Sandpoint stayed at a relatively stable climate much like Portland Oregon is today.  Sandpoint would be much closer to the Pacific Ocean and would not have the large mountain range.  With no mountain range causing a rain-shadow affect on Sandpoint it caused its Kogger-Geiger classification Csb: Warm temperatures-climate, summers dry and warm summer.  I predict that it also much of the precipitation in the winter, because of the polar jets.  Probably more precipitation then present day Portland, because with warmer temperature there is an increase of precipitation.

Present day Sandpoint’s climate has cooled a lot since 100 million years ago.  There is also a lot less precipitation due to the Big Horn Mountain Range.  For more information about present day climate in Sandpoint refer to Blog 3.

100 million year into the future earth will keep changing as it has done since the beginning of time.  Plate tectonics will once again move and will be a large impact on the climate of Sandpoint.  There are several different images and ideas for what earth will look like.  I choose the YouTube video for referring to 100 million years in the futures plate tectonic movement:

As you can see most of the continents move northwest or northeast.  This opens up the Atlantic Ocean and causes the Pacific Ocean to narrow.  The continental drift will open more ocean space, but we cannot see increasing sea level.  This to me indicates that the temperatures will be relatively the same as current day however, not in the same regions.  For instance, Sandpoint moves to roughly 60 N, 135 W now being in the polar region.  The temperatures will be high latitude with long summer daylight hours and long winter nights.  This will cause drastic seasonal variations in temperatures.  As the Greeks theorist would say it is in the “frigid zone”.   The temperatures would be similar to that of Whitehorse, Yukon. Temperatures will rarely reach into double digits above zero.  It will also have low amounts of precipitation and be very cold!

The following are the three climographs based on 100 million years ago and 100 million years in the future (I thought of) and current climate:

Reflection Sandpoint vs Palm Desert

Sandpoint Idaho and Palm Desert may experience contrasting weather patterns throughout the year, but they still have similar climatology.

The biggest similarity would be on the meso-scale climate control with their mountain ranges.  Palm Desert has the San Jacinto Mountains to the west as Sandpoint has the Big Horn Mountain range to their west.  The mountain ranges specifically to the west cause tremendous effects on the climate to the areas of the east of them.  The biggest is the high winds that come off the mountains and the little precipitation that is left for that region.

Another meso-scale that plays a role on both locations is the water that is close to them.  For Palm Desert, the Salton Sea is located just southeast. For Sandpoint, they have Lake Pend Oreille, which is the largest lake in Idaho.  The water does not play that large of a role for these areas, but it is a factor.  The lakes help control some of the temperature changes throughout the night and day (latent heat flux).

Based on the Koppen-Geiger Climate Classification Palm Desert is classified as BWh and Sandpoint is classified as Bsk.  Both locations general climate is B indicating it is an arid climate.  Precipitation wise they are also similar Palm Desert is classified as a desert where Sandpoint is a steep (not quite a desert, but very similar just up to 50 cm more of precipitation).  However since they are located at different latitudes they experience different temperatures Palm Desert is in a hot arid region where Sandpoint is in a cool arid region.  Even though comparably speaking Sandpoint and Palm Desert experiences huge temperature scales they are very similar climatically when talking about precipitation and general climate.
