A passenger mile and automobile mile emit about the same amount carbon, i.e. about a pound of CO2 per mile. Its just a single trans-ocean flight will exceed the amount of driving most do in a year. I dont think many people who go on these international eco-trips pay much attention to this. I have seen some disclaimers in adventurer documentaries that the makers purchased carbon offsets to make trips carbon neutral. Wink wink. Offset try to pay others to cut their consumption so you can increase yours. Or plant a certain number of trees.

Although ground transportation made great strides in employing renewable energy, its hard to see how air travel can. Planes have run off of biofuels. Its hard to see how a plane can store enough electromotive energy to be practical. Requires two orders of magnitude beyond what struggling ground EVs can do. Dsytopian scfi novels have air travel as an extreme luxury when carbon fuels run out, whenever that is.

I posted this under the following Recreation thread. Looks like another in a growing list of Slashdot bugs.

Then evening cartoons disappeared in the 70s and 80s to be restarted by Fox Simpsons, King of the Hill, etc in 90s.

Traveler from Liberia with high fever turned away for two days. Then that ridiculous hospital spokesman on TV trying to explain it away. The only lucky thing is the patient was probably too sick to walk anywhere and cut down on the number of contacts. I feel really safe with a health system as alert as this.

Voxelization is 4-D calculation. Every five years 16x faster computers double the rendering speed. After 20 years you see significnt progress.

Rather than a bunch of silly independent races, designate an interesting single area of Luna to accumulate missions and habitable equipment from all countries. Kind of modeled after Antarctic bases. Remember Antartica was uninhabited for 34 years between the inital polar races (1904-1911) and its first long term bases (1945). World Wars didnt help the situation.

They proclaim a grand goal for NASA and starve its funding.

They look lke black holes from the outside, but are not singulaties. Matter collpses to highest quantum density possible- one plank mass per plank volume- bbut not infinitely small.

Maybe because need to be more alert out in Nature. But I think its because 95% of human history centered around this.

So people could keep tabs of what others were doing out of sight, e.g. on the hunt or left back at home. And when family groups hunkered down in larger groups during winter camp, they could catch up with more distant relatives.

I heard this on Facebook. He-he. Social media is just the modern technological extension of primordial gossip.

Nearly every other month is the hottest month in recorded observation from satellites that measure ocean temps, i.e 2/3rds of the Earth's surface. In the mentime we've had some cold winters and resurgence of ice caps at both pole. Not easy to figure it all once.

If you look at both popular writings and scientific journals from the 18th and 19th century you will see tons of fluff, opinion and wrong results. The sliver of truth perseveres will become next century's science.

Statistical extrapolation say at least half of the systems have them. We can only detect the one percent of edge-on systems with transit method or the fat-fast ones with doppler. But we've barely started to look at the systems within a couple thousand light years. There are millions of starts within this distance.

I've worked in companies during both flush times and tight times. It was nice when they would pay for courses and conferences. But against my advice these items are often dropped first in cutbacks and I observe employee skills suffer. Maybe because I've earned my way through college and have a science background that I decide to still educate myself. Choose the more rewarding conferences, do fewer of them, stay local and cheaper etc. Online training and conference has become better in recent years. I have observed the complainers i.e. "i wont lft a finger to educate myself unless the company pays for it" tend to be let go first in the numerous layoffs I have observed.

These costs are tax deductable once they exceed 2% of your salary, but I havent gone that far yet.
