Port Orford is a small community near the southern tip of Oregon. A small community with less than 2,000 residents, their claim to fame is living in the banana belt of Oregon where temperatures are quite mild compared to the rest of the state. Some residents claim that temperatures in the 60's and 70's in January and July are common. See Port Orford's Current Conditions and gauge the weather for yourself. The Topography of the area creates a diverse terrain with the steep slopes and heavily wooded terrain where the warm winds of California mix with the cooler, moist air of the pacific northwest. In the winter when rain and clouds are likely for most of the Oregon coast, the southern coast of Oregon experiences consistent mild, sunny days. Something known as the "Brookings Effect"has been known for the divergence of wind ultimately creating a 'gap' in weather systems being generated in the Pacific Ocean. Notice in the jet stream prediction model here how Port Orford at just south of 43 degrees North Latitude is far enough south to miss the main current. The micro climate variability is what seems to provide the area with unusually nice weather. As Port Orford is on the coast, the weather is obviously going to be more maritime but will have some effects of continentality because of warmer California winds. Given these factors, the area should have an approximate Bowen ratio of 0.6.

GEEBIT:
A.  A decrease in albedo by .1 for an albedo of -0.1 changes the absorbed energy on the surface of the planet to an average of 375.97 and a maximum of 1503.89. This creates an increase in energy absorbed to the surface of the planet. This also creates an increase in temperature to 43.9 degrees F from 41.9 degrees. An increase in Albedo to 0.1 reduces the energy absorbed to an average of 307.61 and a maximum of 1230.46. This also decreases the temperature of the planet to 28.8 degrees F.

B.  Changing the greenhouse factor to 1.1 increases the energy reached to an average of 526.5 and a maximum of 2106.2. This increase elevates the temperature to 99.1 degrees F. Decreasing to 0.9 changes the energy absorbed average to 486.7 with a maximum of 1946.9 and a temperature of 88.2 degrees F.

C.  Respectively, these changes would not be as dramatic as they would be closer to the equator and inland on the mid latitudes as the climate is typically more mild already. They would increase temperatures dramatically though raising them as much as 40 degrees with an increased greenhouse factor. Reducing the earth's albedo to that similar to Mercury's would be devastating. Reducing the amount of energy absorbed would dramatically affect the warmth of the planet. Being next to the ocean, Port Orford would experience less dramatic shift in temperatures than a location that is more inland, as it does now.
