HSGP Science Night: Climate Science

HSGP Science Night is a meeting to discuss science, philosophy of science and technology.

Science Night will occur monthly on a weeknight, probably not during the summer.

Kick-off meeting: A Tale of Two Climate Scientists

James Hansen:  "Humanity stands on a slippery slope.  As we continue to pump greenhouse gases into the air, we move onto a steeper, even more slippery incline.  We seem oblivious to the danger - unaware how close we may be to a situation in which a catastrophic slip becomes practically unavoidable, a slip where we suddenly lose all control and are pulled into a torrential stream that hurls us over the precipice to our demise."

Richard Lindzen:  "Unfortunately, a significant part of the scientific community appears committed to the notion that alarm may be warranted.  Alarm is felt to be essential to the maintenance of funding.  The argument is no longer over whether the models are correct (they are not), but rather whether their results are at all possible."

The surprising thing is that there is actually a lot of agreement between these two guys.  Their point of disagreement boils down to the nature of feedback in the climate system – Hansen and most other scientist believe the overall feedback is positive, which results in an amplification of the warming signal from CO2 and other greenhouse gasses, while Lindzen believes that the overall feedback is negative, which results in a strongly stable climate system.  What are the scientific arguments in support of or against these two positions?  Who is right?  Only time can definitively answer the second question.  However, if you would like set aside the hyperbole that typically accompanies discussion of climate change and instead look at this issue in the bright shining light of science, then this presentation may just be what you've been looking for.

For more information about this and possible future HSGP Science Nights, go to "More" under our banner at the top of this page. Select "Files" and open the one titled "HSGP Science Night".

This is a free event. You may bring snacks and/or beverages if you wish.

    John showed us the math scientists use to claim anthropogenic causes for global warming.
    Average world temperatures match the math going back hundreds of thousands of years. I hope you will give a talk to the general membership - with much less science, of course - and hit all the other aspects such as the permafrost, the meaning of a rise in 3 degrees, etc.

    Perhaps - why not give it a shot

    John, someone asked if your talk would be o.k. for her very science-savvy 8 & 9 year old kids who attend a science academy. What do you think?

    Oooh! Now I get it! Thanks John.
