With its hovering azure sky and stark landscapes, the yank Southwest is likely one of the such a lot hauntingly appealing areas in the world. but astounding inhabitants development, mixed with the intensifying results of weather swap, is riding the oasis-based society with regards to the edge of a Dust-Bowl-scale catastrophe.

Die Natur, die Welt, die uns umgibt, ist unermeßlich reich an Farben. Der Mensch hat seine farbige Welt selbst seit Jahrtausenden darzustel len versucht. Das geschah in prähistorischen Felsmalereien, während der klassischen Malereiepochen, in farbiger Plastik, in den glühenden Farben der Glasfenster romanischer und gotischer Kathedralen, in der Dichtkunst, im Feuerwerk, in der Forschung.
This used to be the fourth postgraduate summer time university on distant sensing to be held in Dundee. those summer time colleges have been originated via, and proceed to stay in, the programme of EARSel (European organization of distant Sensing Laboratories) operating crew three on schooling and coaching in distant Sensing. the 1st of those summer season faculties used to be held in 1980 on "Remote Sensing in Meteorology, Oceanography and Hydrology".
Worldwide warming is the main major environmental factor of our time, but public reaction in Western countries has been meager. Why have so few taken any motion? during this booklet sociologist Kari Norgaard searches for solutions to this question.

Scientific understanding of that chemistry took a big step forward in 1958 when David Keeling, a thirty-year-old postdoc at the Scripps Institute of Oceanography, began measuring atmospheric CO2 from a station atop Mauna Loa in Hawaii. Fairly quickly, Keeling made two important discoveries. He found that CO2 levels varied with the seasons. There was measurably less in the air during the Northern Hemisphere summer and more during the winter. It was a surprising observation, but one that was soon explained.
Then he was silent, waiting for me to ask another question. He had made his point. World society was going to weaken at one of its weakest points. Hundreds of millions of people live in the water-stressed regions of the world, their situations endlessly variable but their dependence on a scarce resource uniting them in unwanted vulnerability. Unfortunately, their unity of condition breeds a division of interests, as communities and nations compete for precious water, sometimes violently. One of the reddest regions on Milly’s map, which is to say one of the portions of the planet most threatened by a decline in water supply, stretches from Lebanon and Israel through Iraq and Iran to Afghanistan, lands beset by generations of intense conflict, where the stress of water shortage can inflame old grudges.
You can look up, straight up, almost any day of the year, and there it is: an intense, infinite blue, miles deep and beyond reach. It is not merely bluish, not the watery blue of Scandinavian eyes, not the black-mixed blue of dark seas or bachelor buttons, not the hazy blue of glacier ice or distant mountains, but an Ur-blue, an über-blue, a defining quintessence. It is to other blues as brandy is to wine: a distillation, pure and heady. It can be a little deflating to reflect that the ethereal blue of southwestern skies results from mundane forces, that it is the product of solar radiation and atmospheric gases interacting in an environment shaped by climate.
