carbon emisions

[Dodes]

The position we are in for energy is a crisis, we're not close enough to 4th generation nuclear technology or he3 technology or Cold Fusion, and our use of fossil fuels is making are future more and more difficult.

all of this information is based off of the fact that there are still fossil fuel power plants spitting out Co2 to power your computer. if you have your own solar panels or if you get your electricity from wind/hydro/solar it is probably next to nothing, but you have to take into account the fact that it takes energy to build those things/ ship materials. it is still possible to turn this all around, but i think the only way that we will be able to do that is if we make fossil fuels more expensive than bio fuels and other alternative energy sources or if we completely run out. then eventually the world will be running off alternative energy and plants might have a chance to reduce the Co2 we have created.

Wait wait wait wait.
This made me think: after we managed to consume the last drop of oil and burn the last pounds of charcoal... shouldn't our carbon emissions go down considerably?
Talking of that, how far are we from that (oil shortage scares aside and ****) ?

carbon emissions will drop, but the problem is that the carbon already in the atmosphere will be there for a long time
also as technology advances, new drilling methods and equipment will expand the ability to expand fossil fuel supplies

But it'd already be enormously helpful if the emissions went down that much, wouldn't it? 'Sides, we could always plant more of that green stuff.

 

[Mage246]

It takes a very long time for "that green stuff" to reach maturity and become capable of absorbing large amounts of CO2. Plus, we're losing greenery faster than we can regrow it.

depends if we are past the tipping point or not, if we are experiencing droughts and rising sea levels with some places becoming completely uninhabitable. also things like frozen methane deposits melting http://en.wikipedia.org/wiki/Arctic_methane_release would make it harder for plants to grow in the places that they are already naturally growing

We just need a hover-hoover that can suck up all the bad stuff! Yay!

there is a hypothetical device called "an artificial tree", which basically acts as a hover-hoover for co2, although the plan for where that co2 goes is still up for debate (currently the best option is pumping it into the bedrock, which might have some dangerous problems later on and is unpredictable)

also does rejenorst believe in the climate changed caused by humans that is occurring?

Use it in the production of algae based oil.

Going further along that line, algae based fuels seem to be the best way to go in the short term (next 50 years or so), as independence is built away from carbon fuels. There's a lot of great things about algae, such as it doesn't use arable land to produce, has a quick harvesting cycle, can use salt water, etc. The big problem is that for the algae to produce the levels of oil we need, we'd practically need to pump CO2 into the production. We certainly make enough CO2 for that, just there isn't a real feasible way to collect the CO2 that we do produce.

i saw this the other day http://youtu.be/M2Jxs7lR8ZI  really scary that we could be in trouble within this century and yet no one really cares

then i read dodes's post about the artificial trees http://youtu.be/JUSSTYJslXQ there is still hope! (we just need to find the materials for 60 million of them  )

 

[Dodes]

we also have another device of science that could spare us from utter destruction

Stratospheric sulfate aerosols

these can be pumped into the air into to lower the temperature to counteract the increase in global warming

I'm not sure, but I believe they thicken the ozone layer which reflects the sun's rays

the con of the device is that it increases the instability of already unstable weather patterns

 

[Ducksrulez]

yeah... but that sounds like a last resort, we all ready had that happen before from global cooling from particle pollution before we made our cars more efficient, what it did was make the clouds thicker which reflected sunlight making global warming seem as if it wasn't that bad. the only problem with it was that since the sunlight wasn't getting through so  water wasn't evaporating fast

Time to move to canada.

 

[Dodes]

in the postive view of things, greenland will become the new grain belt

 

[mournful]

Time to invade greenland.
