Martian Sea Discovered
mpesce writes "New Scientist is reporting that a large sea of frozen ice (between 800 and 900 km in size and 45 m deep) has been discovered by the ESA's Mars Express Probe. Here's the kicker: the sea of block ice is only five degrees away from the Martian equator. New Scientist also links to a PDF of a paper to be presented next month about the finding." Update: 02/21 15:30 GMT by T : Note: that's 45 meters deep, not 45 kilometers deep.
A new perspective.
I spent several years working in and around the small northern communities in Canada's Arctic.
The Inuit population there refer to water as "molten ice", because ice is the most common state.
Were as we southerners (south of the arctic circle) consider ice as frozen water.
Oh well, I thought it was funny.
Everyone knows that nature is static, and how things were 50, 100, or 1000 years ago are the way that they should be today, tomorrow, and forever!
The reason why large scale or long-term changes to the environment are so risky is not, as you mistakenly state, that nature is static. Rather, it is that nature is highly dynamic on time scales spanning millennia and we don't understand the dynamics yet. A significant change that we think produces benefits may, in the long term, have devastating consequences.
Once we understand natural systems sufficiently well to be able to predict the consequences of our actions in the long term, then we can engage in deliberate planet-wide engineering efforts, here on earth on on Mars. Until then, anything that alters our atmosphere, oceans, or ecology significantly is Russian roulette.
