Comment corrosion, welding and dings (Score 2) 236

...might turn an advanced material vehicle into a Coors can on wheels. Some high strength steels are notoriously susceptible to corrosion, welding and/or post-impact problems.

Unwelded, single piece objects with any necessary protective coatings, or in single use applications, are rapid to develop. We can be excited and apprehensive about these type of advances.

Push comes to shove, the Earth can be CO2 reduced or cooled several ways with current technology, through geoengineering. More pressing is the prospect of global cooling, if the sunspot linked theories continue to outperform the CAGW general circulation models. 2020-2050, and beyond could be a chilly, rough ride.

...complete fabrication by denialists
You obviously weren't there in my grad school. The Ice Age question was a potential concern for an indefinite future of unknown timing. Again this uncertainty was a driver for initial funding on major climate science.

...was 50 years ago.
You miss the point. There is an element of changing perspectives, and repeating fashions here.

"I have a much harder science background"... in climate science? I studied physics and computer science. And I know enough to know what I'm not an expert in.
Climate science is still early stage with lots of contradictions, politics and predictive failures. The models simply do not work from fundamentals. Your assertion of "denialists" as if it were a more mature, proven field with easily observed, successful predictions totally discredits itself with lack of recognition. The internal politics of climate grantees view of their own flaws have been shown to be so fetid and corrupt that adversarial, exploitative cult would be a better discription.

And you slightly demonstrate my thesis of angry dissonant crowds :->
