“Heat waves, droughts, wildfires, floods – all are now more frequent and more intense,” President Barack Obama said during his State of the Union speech last February. “We can choose to believe that Superstorm Sandy, and the most severe drought in decades, and the worst wildfires some states have ever seen were all just a freak coincidence. Or we can choose to believe in the overwhelming judgment of science – and act before it’s too late.”
However, the staff at the Earth Systems Science Center has tracked all the activity of hurricanes, tornadoes and extreme temperatures and found little change during recent decades.
“You can see that hurricanes are not increasing,” Christy told Al.com in June, “tornadoes are not increasing, droughts and floods are not increasing, snow cover is still around – in fact, last winter, the northern hemisphere had its largest extent of snow cover measure.”
