People Under 35 Have Never Seen Normal Global Temperatures | ThinkProgress

“If you’re younger than 26, you have never seen a month where the global mean was as cold as the 161 year average,” observes Robert Grumbine. In contrast, “there are no periods as long as even 20 years of continual below reference temperatures.” He finds that the period 1880-1940 seems to best represent a stable long-term average for global temperatures. If that’s the case, then the “last time the global mean was below the climate normal was March, 1976. If you’re 35 or younger, you have never seen a global mean below climate’s real normal.”

Scientists study surge in heat-related football deaths - dailypress.com

The death rate during football practice was about one per year from 1980 to 1994, but it has roughly tripled since then to 2.8 deaths per year, according to climatologist Andrew Grundstein of the University of Georgia.

Climate change appears to be a factor.

Severe low temperatures devastate coral reefs in Florida Keys

Lead author Dustin Kemp, a postdoctoral associate in the UGA Odum School of Ecology, said the study was prompted by an abnormal episode of extended cold weather in January and February 2010. Temperatures on inshore reefs in the upper Florida Keys dropped below 12 C (54 F), and remained below 18 C (64 F) for two weeks. Kemp and his colleagues had planned to sample corals at Admiral Reef, an inshore reef off Key Largo, just three weeks after the cold snap. When they arrived, they discovered that the reef, once abundant in hard and soft corals, was essentially dead. "It was the saddest thing I've ever seen," Kemp said. "The large, reef-building corals were gone. Some were estimated to be 200 to 300 years old and had survived other catastrophic events, such as the 1998 El Niño bleaching event. The severe cold water appeared to kill the corals quite rapidly."

Did Climate Change Influence Human Evolution? | MedIndia

It is feared that climate change would destroy our species but fossil records have shown that rapid fluctuations in temperature that characterised the global climate between 2 and 3 million years ago coincided with a golden age in human evolution.
