In environmental news, another new study has been released linking stronger hurricanes to global warming. According to researchers, human-generated greenhouse gas have been responsible for more than two-thirds of the temperature increases in those parts of the Atlantic and Pacific Oceans where hurricanes usually form. A study published last year in the journal “Nature” showed a strong link between historical increases in sea temperatures and increases in hurricane intensity over the last three decades. The new study is published in this week’s Proceedings of the National Academy of Sciences.
