In my position I hire a lot of students for a lab work. I've come to realize that the best workers aren't necessarily the people with STEM majors; the best workers are generally people who are interested and feel a little over their head. I've had many terrible pre-meds, and always had good luck with my English majors. If you're willing to start low in the food web, get a job as a lab technician somewhere (universities are often a decent bet). If you can, prioritize places that look like they have work or instruments that you'd enjoy working on. You can amass a pretty good amount of technical skill from a decent lab job.
If you have higher ambitions for aerospace technologies... probably means going back to school. But that would have meant going back to school regardless of your undergrad degree.
I'm sure that it's partially because Slashdot is a high-tech oriented site, but it seems like everyone skips to bizarre schemes before considering any of the really simple, really tame geoengineering options available. There doesn't need to be a fleet of aircraft spaying a mysterious chemical to increase Earth's albedo. There doesn't need to be a techniological marvel at the poles freezing CO2 out of the air. As with most things, simple is better.
Look at endeavors like the Marin Carbon Project (links to published peer-review articles within) which diverts waste, composts it, puts it on managed grasslands and improves plant productivity. Some fraction of the plant biomass gets stored below ground for decades or centuries. The dairy farmers don't need to buy/import as much feed which saves them money (and is an additional CO2 offset). Initial numbers look like 1 ton of CO2 per hectare over a 3 year period from one application.
I'm just not certain why we're looking so hard for lots of difficult solutions when there is so much low-hanging fruit. Some pretty simple changes in management practices (I'm looking at you, agriculture) can go a huge way to not only lowering CO2 emissions, but making land be significant net carbon sinks without compromising productivity.
Disclaimer: In the past I worked with one of the lab groups involved with the Marin Carbon Project.
I don't normally bitch about editing on summaries but, good heavens, does anyone even read this shit? The same "85% of solar energy..." line is used twice. The final line begins with "i-e" which means "that is," but it doesn't reference anything relevant to scaling. What's the appropriate tag here? !sensical? !edited? !proofed?
I'm probably just burning through karma here, but I like to think that if it's a "legitimate" rage, that the body had a way of rejecting the negative effects.
Before CO2 becomes a limiting factor, water and nitrogen come into play. We can fertilize (for a while, anyway), but swings in water availability will make the water part harder.
Even for areas which will become better suited will produce foods will make products that are less nutritious: A recent study published in Nature suggests that in addition to lower levels of iron and zinc, C3 crops produce less protein under increased CO2 conditions. http://www.nature.com/nature/j...
One of the first sentences on the nuclear reprocessing page linked reads "Nuclear reprocessing reduces the volume of high-level waste, but by itself does not reduce radioactivity or heat generation and therefore does not eliminate the need for a geological waste repository." Emphasis mine.
Of course reprocessing would be great, but it doesn't let us side-step the political bungling of the repository issue.
Growing up in the bay area in CA, I've seen my fair share of people who buy into these types of things. I've hung my head many times in shame and disbelief. But at the end of the day, all we need to do is look at the net results of these beliefs to justify how much we should care.
Homeopathy, by definition, cannot hurt you. Due to the serial dilutions used, the chances are that there are 0 molecules of the original thing in any given dose. The worst thing it can do is cost people money for no result. Some people may turn down medicine and take homeopathics instead, but once again, that's only to the end-user's detriment.
Disbelief in, say, climate change is a different story. If you think climate change is all a big lie, you are likely acting to the detriment of everyone else on the planet. If you believe that the world is a self-correcting machines and our actions have no consequences, you are likely acting to the detriment of everyone else on the planet.
So, while new-age hippie BS is annoying, it's generally quite harmless. Not so for the creation museum and its ilk.
