  We're starting to see the evidence that the more intense atmopheric rivers might become more frequent in certain parts of the world and that would contribute to increasing the frequency of flooding.

  The changes Ralph identified are part of a wholesale³ shift in our climate and atmosphere. Deserts are expanding while rain forests are drying out. All due to a  change in the chemical makeup⁴ of the air. This blend has always been in flux⁵. We  alter  the proportion with each breath we take. But our factories and homes, planes and cars amplify⁶ the process. For over two centuries we have been dramatically increasing the amout of the warming carbon dioxide in the atmosphere. So far, the planet's natural air filters have pulled nearly fifty-five percent of it out of the air.

  The North Atlantic has absorbed a tremendous amount of carbon dioxide, but at the moment it's completely saturated⁷ by carbon dioxide, so it's not absorbing very much more. It's almost like a bottle of some kind of soda⁸ pop, it review warmer up a little bit and it actually feels and releases co2.

  As these safety belts close, we'll facing an even more dramatic rise in temperatures
