What does this mean for economies?
- For the first time in recorded history, there are more over-65s than under-5s.
- Aging populations worry economists that certain countries will undergo profound financial stress.
- Yet the current distribution of resources does not allow for further population explosion.
While there's plenty to be worried about, it's important to remember that we're making progress, too.
- If we do nothing, global temperatures could rise as high as 10 degrees Celsius by the end of the century.
- Fortunately, humanity is hard at work at keeping temperature increases below the 2 degrees Celsius mark.
- These 7 projects are just a snapshot of what humanity is collectively doing to fight back and beat climate change.
How can we use the resources that are already on the Moon to make human exploration of the satellite as economical as possible?
If you were transported to the Moon this very instant, you would surely and rapidly die. That's because there's no atmosphere, the surface temperature varies from a roasting 130 degrees Celsius (266 F) to a bone-chilling minus 170 C (minus 274 F). If the lack of air or horrific heat or cold don't kill you then micrometeorite bombardment or solar radiation will. By all accounts, the Moon is not a hospitable place to be.
At high tide each night, bright lights predict the underwater future.
- Lochmaddy is a seaside village sitting at the encroaching edge of the North Atlantic.
- Artists dazzling lights depict the town's submerged future as the oceans continue rising.
- It's an unsettling visualization of global warming's impact.
We are destroying who they are.
- A study finds that human impact is decimating the cultures of chimpanzee communities in the wild.
- Unique localized behaviors are being reduced by 88 percent.
- Socialized learning in chimps has finally been established, just in time to be destroyed.
