Why is one of the lead guys for global warming the same NASA guy who in the late 1970’s said we were headed for a new Ice Age?
Covered that in an earlier post – you’re completely wrong, and it is wrong to lie or continue the lies of others. But I’ll assume you didn’t know, so no sin on your part, but here goes again:
Only a very small handful of scientists were speculating that an Ice Age would be starting – it seemed there had been a cooling trend in decade leading up to the 70s, but later data showed that climate had not been cooling. There was also several other issues being discussed – such as nuclear winter and the cooling affect of aerosols (often emitted when GHGs are emitted). The vast majority of climate scientists in the 70s were predicting warming, not cooling. However, it seems the media went hog-wild with the cooling story.
Since then science as advanced, along with better data and computer power. I seriously doubt any of the scientists predicting cooling in the 70s are predicting it now.

The innuendo that Dr. James Hansen, the NASA climate scientist you seem to refer to, made any cooling trend or ice age predictions is totally false. It was a scientist named Rasool, using Hansen’s computer model and (name removed by moderator)utting an unrealistic 8-fold increase in aerosols, who predicted it; not Hansen. See

When you want to impugn the reputation of a person, it’s important to get the facts straight…and also not judge his/her 40 year old claims by today’s scientific evidence/data and standards in science.
I’ll also try not to make false claims about denialists. I think in this thread I’ve come to understand and respect their sincerity in not accepting anthropogenic climate change; they are not all or even mostly evil shills of the fossil fuel industry, but truly sincere and concerned that mitigating climate change (or passing laws that strive to encourage people to mitigate) will in some way be harmful. ((I just think those laws would be ineffective in reducing ACC…assuming they ever get passed or come up for legislative consideration. The only thing that will work is if enough people & businesses actually start reducing their GHG emissions.))
Why is it that people don’t realize that our planet precesses around the sun and that the elliptical orbit expands and contracts over time- we are now in the orbital phase which puts us closest to the sun in our north hemisphere winter- so its warmer.
I’m a Physicist by training-surgeon by the Grace of God- and I tried to get the data from the AGW people but they wouldn’t give it so that it could be reviewed- from what I’ve seen of the limited release of the 10 Siberian temperature stations their AGW goes up in smoke.
It’s the (non-climate science) physicists that should know about GHG-driven anthropogenic climate change if they were to actuall look into it and study it a bit, but are the ones who are most skeptical. I think it would be interesting to delve into why that is so, perhaps using a sociopsychological approach.
The climate changes due to many factors, so good for you to point these out. I think the climate scientists actually know about the orbit, wobble, solar irradiation fluxes, etc. And also GHGs. This has been well established for many decades, and first discovered well over a hundred years ago.
If I recall the 10 Siberian temp stations OWN their data, and the CRU which purchased right to use it, is NOT at liberty to pass the data on to others. You too could buy their data, I suppose, and they might give it to you if they trust you enough not to spread it to others. I think that was the issue, but I’m not sure.
There is no question about whether ACC is happening in my mind (I had a very excellent science education in HS and college, and read a lot of science on my own). I am only concerned now about to what extent it is a sin to be contributing to people’s harm and death through our GHG emissions. Also about whether denialists who refuse to accept what the climate scientists are saying (no matter how robust the evidence becomes) – are they culpable of venial or mortal sin…or are they as sinless as those who haven’t really heard about ACC, or the people who confuse it with the ozone hole, and think they’ve done their part by stopping their use of hair spray (which no longer has CFCs in it anyway, but many don’t know that).
