The answer isn’t “No”. I'm at a loss as to how "No" has been accepted and circulated as the correct answer. All riddles have an answer or means to solve them. Otherwise they’re not riddles, they’re a paradox. And, until the answer is revealed, you are “guessing” albeit making the best guess possible. And yes, you CAN "guess" or "solve" the riddle. The answer is "pressure” because:
“I turn polar bears white” indicates the increased pressure and heat (climate change) that is melting polar ice in the artic. Pressure makes people cry under stress. Pressure causes the guys to pee. Pressure causes the girls to comb their hair. Pressure causes stress for celebrities. Pressure causes normal people to look like celebrities (game shows, reality shows, heros on the news, etc). Pressure causes heat which turns pancakes brown. Pressure sqeezes CO2 into a champagne bottle for bubbles. Pressure, or squeezing something like a balloon will make it pop, but If you look at a handsome man or prettty woman, “you’ll pop!”, a distractor and play on the word "pop."
