Got any constructive recommendations? We need to stop adding CO2 to the atmosphere and precious little time to do it..... if we don't blame the cause (fossil fuel abuse) then what?
When I was a kid, the ozone hole was the MASSIVE UNAVOIDABLE END-OF-DAYS problem, then the EPA came along and it sorted itself out. There's no solid indication that we can't turn our CO2 problem around before irreparable damage is done, the reaction of the planet to 425ppm may be to freeze the hell out of us. No way to know, we're in uncharted waters.
My personal hope here is new technologies for active reversal of these climate effects that are under development or can be developed.
Unsure about the effects, but there are ways we can (and should) go to actively reduce the amount of CO2 in the atmosphere, not just reduce the amount we add. Most obvious to me seems to be "planting trees"
I have great hope in ocean algae based technology.
Same concept :tongue:

Why would the average consumer buy a new ICE vehicle 12 years from now when we know EVs are better, cheaper and must more in our interest to operate? That's a big part of the problem already half solved.A significant number of people are going to have to be coerced into doing the right thing... that's not finger wagging... that's reality. Being an apologist isn't going to keep us from going over 450ppm... stopping the frivolous use of fossil fuels will. We need more people to have to courage to stand up and say this is wrong and it needs to stop.
The Pope just said we need to go 100% renewable. That should be an indication of just how far we've progressed as a group on the topic.We need more people to have to courage to stand up and say this is wrong and it needs to stop.
Agreed Deonb. That's why the algae are so attractive. Replicating the Carboniferous period basically, but hopefully much quicker yet in a controlled manner. Yes, it will be a giant experiment (just like releasing all the carbon in the last hundred years has been), but probably a necessary one.
Sequestering carbon via algae may be a possible approach; still, let me ask this: about once a year, we hear about an "algae bloom" in the US Gulf of Mexico (generally attributed to runoff of fertilizer nutrients from farms in the Mississippi watershed). When this happens, it is said that this creates a "dead zone," because the decomposing algae cause a major reduction in available oxygen in the water. Fish can swim away from this, but it kills oysters, corals, crabs, etc. Anyway, can we do carbon sequestration with algae, without causing this "dead zone?" Does it have to do with the type of algae that is growing?
400ppm is obviously a big roll of the dice which seems asinine considering options like solar are now at grid parity in a lot of areas, but progress has been so rapid of late that I'm really not all that worried. Once the global financial system truly gets a hold of solar financing it's game over and change will only accelerate to levels we can't even imagine now. Imagine what tactics the big banks will turn to once oil is a permanent bad bet, they'll be racing to finance residential solar before the "boom" passes them by.

With any luck we plateau at 450 and then drop back to historical norms within a reasonable amount of time. Hopefully that much CO2 absorbed by the oceans will not be catastrophic, we shall see. The baby boomers will be dead before you know it and then this will all be a thing of the past.
The physical scale seems massive but the budget scale doesn't. When we're talking about national budgets in the units of trillions, 70 billion / year is doable.There is a proposal to take decomposing trees from forests and bury it:
http://www.triplepundit.com/2008/06/clearing-forests-of-dead-wood-prevents-massive-co2-emissions/
This will help and is simple to implement, but the scale required behind this is massive:
"The dead wood is best stored air tight underground. That way a continuous carbon sink is created. Every square kilometer of forest would fill trenches of 10×25 meters in size and 10 meters deep. Some 10 million of those would have to be dug every year to store 5 billion tons of carbon at a cost of $14 per ton worth of buried wood." (i.e. $70 billion per year)
Or perhaps make into a slurry not unlike crude oil and pump it down the old oil wells... Sequestering is the key.Yes. Easier than planting trees, grows faster, oceans make up 70% of the earth's surface, algae can sink to the bottom thus sequestering carbon.
I suspect it would be easier to grow it in reclaimed sewage out in the desert where there is space and plenty of sun. Plenty of problems to solve making that happen, admittedly, but it needs to be an easy crop to grow, with the less complexities the better.I'm not an expert but I envision this being done far out in the open sea and somehow (this is the tricky part) controlling the grow, spread and decomposition of the algae.
Or simply how bad the problem is, that even the Catholic Church is on board with the reality of Climate Change! Don't get me wrong, I'm extremely glad to see that shift in policy, it just came as a bit of a surprise is all... ;-)The Pope just said we need to go 100% renewable. That should be an indication of just how far we've progressed as a group on the topic.

Most people don't do the right thing until it's forced on them and then 10 years later they don't understand why it took so long. A perfect example is seat belts.. How long did they sit there unused until they passed a law requiring them. Now I don't feel comfortable in the car unless I have my seat belt on.
I say they should have a $10k fine if a new home doesn't have x amount of renewable energy built into it. Like solar panels or equivalent.
