Presta valves have been around long before Bush was president.
Presta valves were used when Global Cooling was the disaster de media. It's obvious the use of Presta valves not only halted Global Cooling; they're continued use is now causing Global Warming. The only solution is to outlaw not only Presta valves but Shrader valves as well. Having two different valve types has been a disaster and adding a third climate neutral valve design could possibly confuse so many cyclists that bicycles would become useless as no one could figure out how to inflate a tire. The new climate neutral valve design must prevent the use of coal-fired power plants as the source of electrical power for climate neutral gas compressors used to inflate the new climate neutral valves. Special compressors with climate neutral valves chucks can be installed in bike shops ensuring cyclists can only inflate their tires from a climate safe inflation source. A coin slot accepting Susan B. Anthony coins can activate the compressor with the money generated going to purchase carbon credits to offset the damage done to the climate from both Presta and Shrader valves. We can also develop new inflation cylinders that don’t use CO2, a green house gas. The new climate neutral valve ensures no destructive CO2 inflation devices can be used with the new climate neutral valve thus ensuring only climate neutral gasses are used in the new cylinders. Of course a carbon credit surcharge is to be placed on all climate neutral cylinders so carbon credits may be purchased to offset prior climate damage from the use of Presta and Shrader valves. Hand pumps must also be banned. Pumping tires manually causes an increase in heart rate and breathing. This causes excess production of CO2 from the person using the manual pump and it would not be possible to collect Susan B. Anthony coins for purchasing carbon credits to offset the damage already done to the climate.
