Research analyzing births in Malta and Western Europe from 1890 to 1995 found a strong association between lower birth rates for boys and colder climates. The study suggests that warmer climates favor the birth of boys, possibly due to temperature affecting fertility and sex ratios at birth.
Researchers at NOAA's National Climate Data Center found evidence that the rate of global warming is accelerating, with recent record high temperatures surpassing expectations. The study analyzed data from 1997 to 1999 and concluded that the rate of warming since 1976 is greater than previously predicted.
