Here's my attempt: greenhouses trap radiative heat by preventing convection. Carbon dioxide traps heat by preventing re-radiation.
Challenge: explain in thirty words or less why climatologists think carbon dioxide emissions are disastrous.
Here's my attempt: write equations predicting climate change using basic physics. Predictions don't match reality, so increase carbon dioxide coefficient until equation matches. No such thing as an unknown variable. What's falsification anyway?
Deck thyself now with majesty and excellency; and array thyself with glory and beauty.
Cast abroad the rage of thy wrath: and behold every one that is proud, and abase him.
Look on every one that is proud, and bring him low; and tread down the wicked in their place.
Hide them in the dust together; and bind their faces in secret.
Then will I also confess unto thee that thine own right hand can save thee.
I could not love thee, dear, so much,
Loved I not Honor more.
