Meteorologists are often asked to explain why our weather seems so extreme these days.
While it's difficult to nail down a specific cause, the American Meteorological Society just released an in-depth report with some answers.
Scientists linked the changing climate to six of last year's biggest disasters -- including the drought in KELOLAND. While the government generally stays away from the issue, three of the four main authors work for NOAA, the National Oceanic and Atmospheric Administration.
Looking at last year's drought, scientists say the weather pattern was mostly natural but that kind of event is more than four times as likely to occur now than before the Industrial Revolution. That means drought could become a more common occurrence in the Northern Plains if this trend continues.
The report also says human-caused change also led to 2012's record spring heat.
While it remains difficult to directly tie weather and climate together, some scientists say last year's billion dollar disasters show that there is a link.
