Study: Man-Made Global Warming First Became Evident In the Mid 20th Century

TapeCutter writes: In 1958 the US National Academies of Science (NAS) warned the US government that they had detected a robust Anthropogenic Global Warming (AGW) signal, they have not changed their mind on that claim for 57 years. Like the modern day Al Gore, Frank Capra publicized the possible effects in a popular documentary (video). Today we have news of a study from Melbourne University claiming the effects of AGW first became evident in the mid 20th century. In other words, the NAS could not have picked up the signal much earlier than they actually did. The fact that the last serious scientific objection to AGW (as a theory) was overcome in the mid 20th century by improving spectrometers in heat seeking missile was a remarkable coincidence, NAS took full advantage of that opportunity.

That may or may not be true...

...but I'm still not going to turn off my AC, stop driving my truck, or move into a smaller house.

The only real solution is going to be figuring out how to provide power cleanly for less money than doing it dirty.

Anything else is just an illusion, it won't be used by enough people to matter. You need to provide people a reason to change, and telling them to pay more money to save planet Earth isn't going to be it.

I'm all for clean power, to a point... but when it is less reliable and costs more money than the existing options, you just aren't going to get anywhere.

More nope

But all evidence points towards AGW

Sigh. No, it does not, and has not for years.

All of the models are wildly wrong in predicting climate, so the "evidence" is pointing against any of the alarmist models you are peddling being correct.

CO2 has risen substantially in the last decade or two - with very little corresponding warming. There are a lot of theroes and hand-waving why, but in the end the EVIDENCE is that CO2 rising does not lead to temperature rise, despite many previous predictions to the contrary.

Previously we were all told Global Warming would bring more extreme storms, but the extremity of storms has remained slightly below average in recent years.

When will you zealots wake up to what real science (and real, vs. massaged, data) has been trying to tell you? You can go peddle e-meters or find some other gullible idiots to scam. At least then you wouldn't be screwing over the Earth with your crackpot religion.
