A reader emailed me wondering why he was having such a hard time finding canned pumpkin in the grocery store.
"I recall buying canned pumpkin in the summer months before because I bake pumpkin chocolate chip cookies a few times each year," Don Sauer of Raleigh wrote.
Sauer remembered the pumpkin shortage of 2009 and wondered what was going on this year in the pumpkin world.
Two studies suggest extreme rainstorms and snowfalls have grown substantially stronger, with scientists for the first time finding the telltale fingerprints of man-made global warming on downpours that often cause deadly flooding.
Two studies in Wednesday's issue of the journal Nature link heavy rains to increases in greenhouse gases more than ever before.
Both studies should weaken the argument that climate change is a "victimless crime," said Myles Allen of the University of Oxford. He co-authored the second study, which connected flooding and climate change in the United Kingdom. "Extreme weather is what actually hurts people."
