magazine reported that Lindzen is "willing to take bets that global average temperatures in 20 years will in fact be lower than they are now." Annan contacted Lindzen to arrange a bet and they exchanged proposals for bets, but were unable to agree on terms. The final proposal was a bet that if the temperature change were less than 0.2 °C (0.36 °F), Lindzen would win. If the temperature change were between 0.2 °C and 0.4 °C the bet would be off, and if the temperature change were 0.4 °C or greater, Annan would win. Lindzen would take 2 to 1 odds.

In 2005, another bet for $10,000 dollars was arranged with a pair of Russian solar physicists Galina Mashnich and Vladimir Bashkirtsev. The bet will conclude in 2017.

Disc-brake equipped bicycles

In addition, he has also claimed that the moments in disc brake
Disc brake
The disc brake or disk brake is a device for slowing or stopping the rotation of a wheel while it is in motion.A brake disc is usually made of cast iron, but may in some cases be made of composites such as reinforced carbon–carbon or ceramic matrix composites. This is connected to the wheel and/or...

 equipped bicycles can overcome the retention force of the dropouts, causing wheel ejection and subsequent loss of control. At least one manufacturers now seems to be agreeing with him. He proposes mounting the brake caliper on the trailing edge of the fork blade instead of the leading edge to rectify this.
