At the United Nations meeting on climate change next week, scientists will be discussing some of the potentially devastating effects of global warming, such as rising temperatures, melting ice caps and rising sea levels in the near future. But Earth's changing climate is already wreaking havoc in some very weird ways. So gird yourself for such strange effects as savage wildfires, disappearing lakes, freak allergies, and the threat of long-gone diseases re-emerging.
Wasteful energy policies, overuse of resources, water supply shortages, global climate change, and deforestation are just some of the issues experts say need to be addressed at the U.N. Climate Change summit in Copenhagen beginning this week. Here are 10 technologies - some old, some new, some a bit offbeat - that might help.
Exposing kids to nasty germs might actually toughen them up to diseases as grown-ups, mounting research suggests.
With world leaders gathering at a U.N. summit in Copenhagen to brainstorm ways to quash increasing temperatures and hold back rising seas, LiveScience takes a look at the state of Earth's ecosystems and its inhabitants - from polar bears to us. Here are 10 signs of how well (and not-so-well) our planet is doing.
