Our technology is getting better and better right now—as we build off of each new improvement in materials (including nanotechnology), computing power but more important amazing new software to take advantage of that computing power, as well as a much deeper understanding of the atmosphere, the oceans etc.
The “ridicule factor” scared off scientists for decades, but now we have enough heavy hitters working on it to make real progress.
In addition there are more and more scientists ready to throw out the old dogmas and let the data drive the science instead of old prejudices. That is the only way to get a handle on this topic.
