And you are so right...we Australia are a relatively affluent country,
as is yours,...What do we do, we the affluent nations do, to support country's less affluent?? Support their emergent needs to food and water??? See my point is, it can't wait till we fix a war in the middle east, this drought keeps marching on across the WHOLE of the Southern Hemisphere.. |

And in expanding our perspective even further - how about "Life on Other Planets" Wednesday's news, but worth reading. Debating whether suns other than our own have planets has always been like debating whether cats other than your own have kittens. The answer is self-evidently yes. All stars form more or less the same way after all — coalescing out of the same celestial gas and often leaving a dusting of the stuff behind that can, in turn, coalesce into planets. All stars can additionally snag passing bodies in their gravitational lasso, conscripting new worlds to add to the home-grown litter. So it was no surprise in the early 1990s when astronomers began detecting these so-called extrasolar planets circling distant suns, and it's no surprise that in the years since they've spotted more than 220 of them. But the latest one added to the list is by far the best. On Tuesday, a team of European astronomers announced that they had not only found a new planet circling a comparatively nearby star in the constellation Libra, but that that planet is unexpectedly Earth-like. Like Earth, it orbits a comfortable distance from its sun; like Earth, it maintains a surface temperature somewhere between 32 and 104 degrees Fahrenheit. Most importantly, like Earth, it could easily harbor surface water. In the biological arithmetic we know best, warmth and water often equal life. For all its terrestrial feel, the new planet — unpoetically dubbed Gliese 581c — has a decidedly extraterrestrial look. It is probably more than 1.5 times the diameter of Earth and five times heavier. But unlike our world, which orbits a comfortable 92.9 million miles from the flames of the sun, 581c hovers just 7 million miles from its home star. What prevents it from being incinerated like a match head is that its star is a red dwarf, only about one one-hundredth as bright as the sun. The dim light coupled with the planet's close proximity places it in what astronomers call the habitable zone: the spot at which temperatures remain comfortable and water can remain liquid. All this has led to a fair amount of astronomical hyperventilating. "On the treasure map of the universe, one would be tempted to mark this planet with an X," said Xavier Delfosse, an astronomer with Grenoble University in France and one of the planet's co-discoverers. Dmitri Sasselov of the Harvard-Smithsonian Center for Astrophysics, went further, enthusing to The New York Times, "It's 20 light-years [away]. We can go there." (Sasselov did not make it clear just how we'd make that 120 trillion mile trip when it still takes us eight months to cover the 35 million miles to Mars.) Even if we could visit 581c, there would be reasons to wait a bit before we light the rockets. For one thing, just because the planet could have liquid water doesn't mean it does. The body was detected like all extrasolar planets initially are, not by direct observation, but by measuring the infinitesimal gravitational wobble it causes in its home star. We won't get a clearer sense of its makeup until its orbit carries it in front of the star and the brief interference in the wavelength and intensity of the incoming light allows us to make some inferences about its composition. This will also tell us if the planet has an atmosphere and if it is thin and wispy like Mars's or suffocatingly dense like Venus's — neither of which promises good things for the kind of life we're most familiar with. What's more, there are plenty of far more promising places to hunt for life closer to home. Sunlight is not the only kind of energy that can fire the biological furnaces; so can subsurface heat. Jupiter's icy moon Europa is thought to have a rich, salty, globe-girdling ocean sloshing just beneath its surface rind of water ice. Very little solar light reaches so far into space, and even less makes it down to the dark ocean inside Europa. But the gravitational flexing of the little world caused by the movement of Jupiter's other moons heats up its innards the same way a wire hanger heats up when you bend it back and forth. This is what keeps Europa's ocean liquid, and this could could also help spark life. Mars too could be home to similarly hearty subsurface life forms, as could two of Jupiter's other moons, Ganymede and Callisto. If the discovery here on Earth of tough little organisms living miles below ground, frozen in polar ice and hanging on in the broiling waters of deep-sea vents indicates anything, it's that biology emerges in very improbable places. The most remarkable thing we may come to conclude about 581c is that whatever secrets it holds may not be that remarkable at all. |

I was reading and the nuke power might hold the key to the energy costs,
and they are coming up with new technologies for the desalination process, that enables most of the salt to be used for table salt, lick blocks for livestock, and all kinds of stuff like that. The water really doesnt contain all that much salt per gallon and is the least of the problems. The big one is energy costs.. I think a pipeline could transfer the water inland... |

Meanwhile, back on Earth Vancouver, BC to be specific This winter we had record snow falls about 3X the average and have had heavy rain for a looong time A lot of the Lower Mainland areas that are at low elevations (including the 'burbs where I live) are preparing for flood conditions. Its not just the water damage but its also the pollution and health and safety concerns for people and animals. We should expect the worst toward the third week of May. I've been involved in the committee of volunteers organizing efforts. *sigh* |

I like space too, although I am more concerned with the travel portion
of it, than the et life. I was reading about the new fuels they are planning on using to travel to places like that planet and the various other things that are needed for that long of a flight, like water, food, and oxygen. Thats where I want to take my education and use it When I graduate, of course Ill never really quit going to school, probably for the rest of my life,, I love learning and there is so much to learn...... |

Great post Purple Goddess...interesting, and also kind of remarkable..
We have all this technology, this interest, in finding habitable planets, even if we aren't sure how we might get there.. and I am sure someone will figure it out.. and yet we can't figure out how to fix our own problems, that have been created here.. Logistically Fanta, pipelines are possible, dams didn't work...they aren't self replenishing...they need that rain stuff.. Australia, state by state is in trouble...Victoria, South Australia, Western Australia, New South Wales, South East Queensland..we are not in a good way...agriculturally, environmentally, water-wise. And yet, we look and smell great, in comparison to AfriKa, India, and parts of Asia, South America, and in the North as well, China, Middle East, Russia..and on it goes..drought is huge globally.. |

HUGE........
Well, sleep concerns me now, but I will think and read more tomorrow.... G-night ladies, and dont spread it around that I actually think about more than war and being a smartass... OK One more thing the fuel for space travel that far is actually the simple thing It is solved with a small nuclear reactor, doesnt have to have a lot of thrust, because there is a vacum in space. the craft has no resistance and the speed just continues to gain the longer in flight. there is no way to estimate how fast because it is unlimited,,,, the problems are mostly with.. water. go fiqure.... |

Is it much more than seaonal snow melt there? The rainfall, is not seasonal?? And Alex is experiencing the hottest April in Amsterdam for 300 years.. Hmmmmm...houseboat, de-sal plant, surfboard and doughnuts..may be the emergency kit of the future.. |

Drought Threat For Australia Irrigation
Southern Australia Will Have No Water For Irrigation If Drought Continues, Leader Says CANBERRA, Australia, Apr. 19, 2007 (AP) Australia's worst drought on record got tougher Thursday when the prime minister announced there won't be enough water for irrigation along the country's largest river system unless there's significant rainfall soon. Prime Minister John Howard, releasing a new report on the health of the Murray-Darling rivers, said the dry spell was "unprecedentedly dangerous" for Australian farmers and the economy as a whole. "If it doesn't rain in sufficient volume over the next six to eight weeks, there will be no water allocations for irrigation purposes in the basin" until May 2008, he told reporters in Canberra. The affected states would first need to agree to the ban, however, which a government weather forecaster predicted may be unnecessary thanks to expected above-average rainfall over the next three months. The Murray-Darling river basin spans five Australian states and accounts for about 85 percent of the nation's irrigation supply. The waterway generates around 40 percent of Australia's farm produce and supplies drinking water for the South Australia state capital, Adelaide. But the country's prolonged drought has reduced the rivers to a trickle, crippling Australia's farming sector and forcing many cities and towns to enact drastic water restrictions as reservoirs dry up. Howard said there would be water only for "critical urban supplies" plus farmers' domestic use and watering stock. "The impact that this is going to have on industry, on the horticultural industry and crops like grapes and stone fruits and other primary industries that rely on irrigation including the dairy industry, is very critical indeed," Howard said. National Farmers' Federation chief executive Ben Fargher said thousands of farmers could lose their citrus, almond and olives trees if they cannot be watered this year _ losing production for more than five years. Climatologist Blair Trewin, of the Australian Bureau of Meteorology, said the basin's northeast had more than a 60 percent chance of above-average rainfall before June. The southern part was likely to experience average rain in the same period. "We think it's extremely unlikely that this year is going to be anywhere near as bad as last year," Trewin said of the extraordinary drought. "It looks quite encouraging, particularly for later this year." Howard said it was too early to estimate the economic impact of an irrigation ban. "We know already that the drought has taken three-quarters to 1 percent off our growth," he said. "The longer it goes on, the harder the impact." In January, Howard announced an $8.3 billion program to overhaul thousands of miles of irrigation pipes along the Murray-Darling river system. Under the plan, the federal government would also assume regulatory control of the rivers from the four states that currently administer irrigation rights. All states but one _ Victoria _ have agreed to the plan. National control of the water is contingent on all states being part of the plan. An irrigation ban could not be forced on Victoria. Victoria Premier Steve Bracks said he would not budge on his refusal to join the national scheme, despite the looming crisis. Neither the state nor the federal government has been willing to make public their differences over the plan. |

Read further Fanta.
Urainium like all other minerals is a finite resource within the earth. It also is close to depletion as is copper, oil, natural gas, all the other rare earths, gold, (you name it). Why do you think it is gettin more expensive to mine things. We must go deeper or process more dirt/rock to get the same amout of minerals we used to get. We need something quite different for our future energy source. We need to find it quite quickly or watch future generations learn to become cavemen again. Or go out into space to find other sources for it. |

Nice thread Jess.
As I look outside my window I see spring. The trees are budding, plants a blooming and bees a buzzing. I know, I know that is not what you meant but sometimes it is a good thing to look closely within your own box and count the blessings stored there. When set you sight once again outside that box it is with renewed vigor. |

Doo doo doo looking out my back door!
Lets see, Setzer is begging for food even tho he has some out there (hes a local stray), wild rabbits are building a den in the yard, and the tree that got struck by lighting seems to be doing just fine after being caught on fire a few days ago. News is always depressing, thats why I go play with my cats and drive down to "Kentucky Down Under" and see Jess's backyard ^.^ |

Drought in West Texas area too, extended over decades. Over 40 years
they have nearly depleted an enormous underground reservoir called the Ogalala, which runs from Nebraska down through Oklahoma and eastern Colorado to Texas. When once they could drill a water well a hundred feet and irrigate a cotton farm with it, now they have to go thousands of feet. Water will be an ongoing problem. I'm getting thirsty just thinking about it. Actually I'm a little worried about the cotton farmers. |

Good morning
AB...it isn't rocket science, is it? Resources...are not infinite..the domino effect of this fragile planet...(sigh). And yes, both Allen, and you, see how I see, I do see my backyard, my front yard, through every window, sometimes my backyard wanders in to see if there's anything about to eat. It's why I guess, I do look further out of my box.. |
|
|
|
Jess I was in your back yard too, I wanted food but you said "no!" and
slammed the door in my face =O I just wanted to see you in your bikini and tank top =P |
|
|
|
Allen, at 'Kentucky Down Under', do they talk to you about the native
animals from here, their natural habitat? Just wondering.. |
|
|
|
Yeah they do! And they have Australian grass and dirt and even rocks! I
asked if I could have one of the rocks and they were amazed that someone wanted something so random lol. But still no wombats =O |
|
|
|
Wombats are tricky critters, and the Northern Hairy nosed wombat has
been having a hard time, their habitat has been so greatly reduced...it isn't so conducive to them breeding..so their numbers are dropping. Seems strange, to have Aussie dirt, and rocks, and trees in another country, but kind of cool too.. and I guess it's no different to what this government is doing, selling the rocks and dirt, and whats under the dirt, to other countries.. |
|
|
|
But its cool, its like going to another country for a day =D And it had
a wonderful history on Aberigonies (sp?) |
|
|

Indigenous Australians...formally known as Aborigine by us white
settlers, they call themselves Koori, or Murray, depending on where they are from.. |
