Delta growth, Louisiana
Most of the Mississippi River delta plain is losing ground, but new land is forming in Atchafalaya Bay at the mouths of the Wax Lake Outlet and the Atchafalaya River. Wax Lake Outlet is an artificial channel built to reduce the severity of floods in Morgan City, Louisiana. The Atchafalaya is a distributary of the Mississippi River. Combined, their deltas grow an estimated 2.8 square kilometers (1.1 square mile) per year. Floods transport large amounts of sediment to Atchafalaya Bay, while hurricanes redistribute sediment within the bay and destroy coastal vegetation that would otherwise protect land from erosion.

Imagine a place where there are 131 frog-eating bats, 34,140 Cretaceous Molluscs, 40 terabytes of data of stars, planets and galaxies, and to top that 86,881 samples of tissues and DNA. Where we have samples from the field of Paleontology, Anthropology, Vertebrate and Invertebrate Zoology, and Physical Sciences. This is the place where global history resides and preserved. This is the American Museum of Natural History.
The Shelf life collection at AMNH has reached more than 33,430,000 specimen and artifacts. From centuries-old specimens to entirely new types of specialized collections like frozen tissues and genomic data, the Museum’s scientific collections, form an irreplaceable record of life on Earth, the span of geologic time, and knowledge about our vast universe.
These specimens are the symbol of our Earths past life form. They are presently dead specimens of a vivid living past. They explain evolution of species (Darwin) and evolution due to catastrophism (Cuvier).
Photographer Alexey Kljatov takes incredible close-up photos of snowflakes in his backyard in Moscow.
“I capture snowflakes on the open balcony of my house, mostly on glass surface, lighted by an LED flashlight from the opposite side of the glass, and sometimes in natural light, using dark woolen fabrics as background.”
“There is something fascinating about science. One gets such wholesale returns of conjecture out of such a trifling investment of fact.” Mark Twain
Still believe there is no anthropogenic activity involved in global warming? Well you won’t think so after watching this video!
An ultra-high-resolution NASA computer model has given scientists a stunning new look at how carbon dioxide in the atmosphere travels around the globe. Plumes of carbon dioxide in the simulation swirl and shift as winds disperse the greenhouse gas away from its sources.
The carbon dioxide visualization was produced by a computer model called GEOS-5, created by scientists at NASA Goddard’s Global Modeling and Assimilation Office. In particular, the visualization is part of a simulation called a “Nature Run.” The Nature Run ingests real data on atmospheric conditions and the emission of greenhouse gases and both natural and man-made particulates. The model is then is left to run on its own and simulate the natural behavior of the Earth’s atmosphere. This Nature Run simulates May 2005 to June 2007.

Global warming is generally reflected as increase in radiation budget or increase in the green house gases or decrease in albedo created by glacial ice.
The temperature rise can be easily reflected in the retreat of glaciers. The calving process is common now a days. These are the pictures which proves the global temperature rise.
