Animals, plants already feeling effects of global warming

Global warming is having a significant impact on hundreds of plant and animal species around the world — although the most dramatic effects may not be felt for decades, according to a new study in the journal Nature. “Birds are laying eggs earlier than usual, plants are flowering earlier and mammals are breaking hibernation sooner,” said Terry L. Root, a senior fellow with Stanford’s Institute for International Studies (IIS) and lead author of the Jan. 2 Nature study. “Clearly, if such ecological changes are now being detected when the globe has warmed by an estimated average of only 1 degree F (0.6 C) over the past 100 years, then many more far-reaching effects on species and ecosystems will probably occur by 2100, when temperatures could increase as much as 11 F (6 C),” Root concluded.

Loneliness puts elderly at risk for heart disease

Loneliness, lack of emotional support and lack of companionship or social support can leave elderly men and women vulnerable to heart problems. Dara Sorkin of the University of California, Irvine, and colleagues found that for every unit increase in loneliness as measured among older adults in their study, there was a threefold increase in the odds of being diagnosed with a heart condition.
