Albedo Quotes & Sayings

There is no limit on the level that the reflections can be at and in a modern environment, such as a city, the albedo can increase the power levels many times of the sky based solar radiation of direct and diffuse combined. The trees prevent the albedo reflections from occurring. — Steven Magee

The global surface albedo [surface whiteness] and greenhouse gas changes account for practically the entire global climate change. — James Hansen

Dear Dr. Ortiz - Congratulations on your discovery! We found the object, too, about six months ago and have been studying it in detail for the past few months. It has a few interesting properties that you might find interesting. Most interestingly, it has a satellite, and the orbital solution gives a system mass of about 28% of that of the Pluto-Charon system. It's still probably the biggest KBO around but it has a sufficiently high albedo that it is not quite as big or massive as Pluto. I've got a paper describing the satellite that, ironically, I was planning to submit tomorrow. I will forward the paper to you as I submit it. I am sure that I will get inquiries about your new object from different people; is there [or is there going to be] a website describing your survey or your discovery that I can point people to? Again, congratulations on a very nice discovery! — Mike Brown

The beauty of Mars exists in the human mind," he said in that dry factual tone, and everyone stared at him amazed. "Without the human presence it is just a collection of atoms, no different than any other random speck of matter in the universe. It's we who understand it, and we who give it meaning. All our centuries of looking up at the night sky and watching it wander through the stars. All those nights of watching it through the telescopes, looking at a tiny disk trying to see canals in the albedo changes. All those dumb sci-fi novels with their monsters and maidens and dying civilizations. And all the scientists who studied the data, or got us here. That's what makes Mars beautiful. Not the basalt and the oxides — Kim Stanley Robinson

When we consider the fact that nearly three-quarters of the surface of the globe is covered by oceanic water, we begin to realise that the molecular scattering of light in liquids may possess an astronomical significance, in fact contribute in an important degree to the observed albedo of the earth. — C. V. Raman

The Earth is bathed in a flood of sunlight. A fierce inundation of photons - on average, 342 joules per second per square meter. 4185 joules (one calorie) will raise the temperature of one kilogram of water by one degree Celsius. If all this energy were captured by the Earth's atmosphere, its temperature would rise by ten degrees Celsius in one day. Luckily much of it radiates back to space. How much depends on albedo and the chemical composition of the atmosphere, both of which vary over time. A good portion of Earth's albedo, or reflectivity, is created by its polar ice caps. If polar ice and snow were to shrink significantly, more solar energy would stay on Earth. Sunlight would penetrate oceans previously covered by ice, and warm the water. This would add heat and melt more ice, in a positive feedback loop. — Kim Stanley Robinson
