The world has a finite amount of money, something you collectivists seem unable to grasp.
Finite?!?!? No WAY Dude! Money grows on trees. Marx told us so.
We can either spend loads of cash developing and deploying a asteroid detection/aversion system....OR we can spend that money in an attempt (who's primary unintended ((or is it intended?)) consequence is to REDUCE the economic output of the planet...which will even further reduce the amount of cash available for an asteroid defense system.
Really? Those are our two choices? Is your side of this argument REALLY that lacking in substance?
As far as the benefit of a warm world we have ample historical evidence to support that assertion. The Romans wrote extensively about their world and so did the medieval scholars. They present more than enough compelling evidence to show that they benefited GREATLY from the warm world they enjoyed. Conversely if you wish to experience a pestilential, famine ridden warring world then look no further than the Dark Ages which enjoyed a cooling period so severe it is called the "6th Century Climate Catastrophe".
You are one confused poster. There was no cool period in the 6th century. The Dark Ages is a loaded term with a variety of definitions,
none of which involve climate. The coolest period in the last several thousand years was the LIA from the 14th to the 19th century. And, of course, no one writing during the Roman era, the MWP or the LIA would have been able to describe the effect of differing climate regimes on present day human culture. They didn't have the population or the industry. And, as has been pointed out to you repeatedly, the temperature change that has taken place in the last 150 years has occurred at a rate not seen in tens of millions of years. No HOMINIDS, much less modern humans, have ever undergone climate change at the pace we are currently experiencing.
So, the only people who seem incapable of carrying on a logical scientifically based discussion are you and yours.
Irony, thy name begins with 'W'.
