Global Warming: What We Knew in 82

In 1982, Mike MacCracken, then a senior researcher at Livermore Laboratory, gave a lecture at Sandia Labs on the subject of global climate change.
I talked to Dr. MacCracken not long ago at the University of Michigan,and asked him, if he were to give the lecture today, what would be changed, and what would be the same.

2:16, records that have lasted for 100 years? LOL 100 years in geologic time does not equate to a damn thing. These people are so ignorant......seriously, one learns simple basic concepts of climate and time in intro geology courses. You don't have to be a Phd to see the holes in the basic knowledge of these people.

[greenman3610]

climate deniers who claim to see the big picture of time make me laugh, and prove my point.

If you want a 3 billion year overview, google Richard Alley's lecture "The Biggest Control Knob", or check the National Academy of Science publication "Origin and Evolution of Earth".

It's the sure sign of arrogance and ignorance that someone like this assumes they know more than experts who have spent their lives asking the big questions.

[MrDoglvr1]

The CO2 graphs used by the climate "experts" conveniently don't mention that CO2 levels actually rise AFTER the temperature rises. You got your cause and effect backwards

[greenman3610]

you reveal that you've learned your science at conspiracy websites, not the literature.

Before an accurate assumption ON GLOBAL WARMING can be obtained more information must be on the table namely radiation the basic key to life on the surface of the planet balanced by the protective shield which regulates the amount of GOOD and BAD radiation into the biosphere.There is missing information of the cause and effect of burning radioactive material in our biosphere until then everything is based on an inaccurate premise with a common conclusion.

Remember: politicians don't come up with solutions. Engineers and scientists do. Politicians are temporary and are more interested in short-term $ than in long-term sustainable solutions. They represent the 1%, not the 99%.

Each day provides a new opportunity for us to live an extraordinary life; and leave our legacy for the World to cherish. What positive lasting changes do you hope to be remembered for long after you are gone from this beautiful planet?

Yes, it is amazing how climate deniers do not see the red line (09:00 into the movie)...
