Is Global Warming an immediate threat to national security?

Do we contribute? Yes. How much? There's the rub. Interesting thing is the Sun appears headed for its periodic quiet time by 2030 which takes us into the mini ice age period. So by the time we're out of it, hopefully technology that's affordable and makes sense will lessen our planetary footprint. Unrestrained population growth will be dampened by the limited food supply. So about the year 3000, we can harvest the trees to make real Stradivarius instruments again. The shape and glues have been long figured out. It's just the wood doesn't exist right now to make that sound.

No. It's a monetary scheme created by lazy pseudo scientists who get paid with taxpayer funded grants. They appeal to greedy politicians who want more tax revenue who in turn give more grant money. It's a mutually beneficial, symbiotic relationship.

Okay this is total malarkey!
