Reading Assignment: Chronicles of Ice Summary: In Chronicles of Ice‚ Gretel Ehrlich sets out to “learn whatever lessons a glacier has to teach”‚ and to share what she has learned with us‚ as readers. The lesson the author relays to us is that the fate of the glacier is inextricably linked to that of the biological health of the Earth itself. Ehrlich uses the glacier as a device to show both cause and effect of the declining health of the Earth’s climate. The gases and particulate trapped in the ice

transmissivity of the slant path of the atmosphere at a given wavelength is given by: (2) where u is the optical depth of the vertical column and is given by (3) and Z is the zenith angle of the sun we also know that the transmissivity and the albedo‚ A‚ are related by (4) Rayleigh scattering Rayleigh scattering theory describes the interaction of sunlight with molecules in a simple way. It applies to particles much smaller than the wavelength of the incoming radiation. For Rayleigh scattering

of Earth. In May 1 issue of the journal‚ Geophysical Research Letters‚ published by the American Geophysical Union‚ a team of scientists from the New Jersey Institute of Technology and the California Institute of Technology report that Earth’s albedo‚ the fraction of sunlight it reflects‚ is currently 0.297‚ with a margin of error of 0.005. "Earth’s climate is driven by the net sunlight that it absorbs‚" says Philip R. Goode‚ leader of the New Jersey Institute of Technology team‚ Director of

1. Searching for potential life on exoplanets Despite the rapid improvement in technology the past few years‚ the current technology is not capable of yielding a completely successful mission that would travel to other stars and search for habitable exoplanets. Fortunately‚ the number of solar systems and exoplanets discovered is increasing. Direct images received from those exoplanets have a very low resolution but provide plenty of useful information. This essay will examine how this information

I and III only D. II and III only Remember that the GWP represents the relative contribution of one molecule of the atmospheric gas to global warming. 12. Land use changes have a big impact on global warming because of their effect on albedo. Albedo A. is the primary wave number at which a greenhouse gas absorbs infrared radiation. B. describes the effectiveness of a molecule as a greenhouse gas. C. is the ratio of electromagnetic radiation reflected by a surface to the amount of radiation

Almasan Submitted to : Prof.Landingin “ NASA’s WISE Finds Mysterious Centaurs May Be Comets” New observations from NASA’s NEOWISE project reveal the hidden nature of centaurs‚ objects in our solar system that have confounded astronomers for resembling both asteroids and comets. The centaurs‚ which orbit between Jupiter and Neptune‚ were named after the mythical half-horse‚ half-human creatures called centaurs

Have you ever heard of the second largest classic explosive eruption of the twentieth century? The purpose of this report is to examine the cataclysmic eruption of Mount Pinatubo in June 1991. This volcano is located on the island of Luzon in the Philippines; a mere 90 kilometers (55 miles) northwest of the capital city of Manila (Rosenbu‚ 2010) (see Figure 1). Specifically‚ this report will give a vivid description and information about the volcano. It will discuss a variety of factors related to
