The Denver Post reports:
7NEWS Chief Meteorologist Mike Nelson put the report in a form even Broncos fans can understand:
“The climate is changing and warming due to increased greenhouse gases. However, there is a big difference between weather and climate. Weather is one play in a football game. Climate is the history of the NFL. Climate change is adding Peyton Manning to your offense. In other words, we are juicing the atmosphere and we will likely see an increase in extreme weather. Ninety percent of what we see is natural variation. The ‘Peyton Manning effect’ is the extra 10 percent.
“What this means is that a heat wave might be just a little hotter. A drought just a bit dryer and an extreme precipitation event just that much wetter.
