We've never seen a year like this before

DR. JEFF MASTERS, meteorologist: "We have never seen a year like this before…."

KATHARINE HAYHOE, climate scientist: "As it gets warmer, the air can hold more water vapor. So whenever a storm comes through, there’s more water available to that storm, whether it’s rainfall in the summer or even snowfall in the winter."

"We’re also seeing shifts in our weather patterns and circulation patterns. So, some places that are already quite dry are getting dryer. Other places that are already quite wet are getting wetter. And some places can even experience increases in heavy rainfall events and droughts at the same time, because if a lot of the water vapor comes down in a few storms then you have a longer dry period in between before you get the next one."
