Overpopulation: The root of the world's biggest problems?

Think about this:

  • It took millions of years for humans to reach a population of 1 billion
  • That milestone happened about 200 years ago
  • 100 years ago, there were 1.6 billion people around
  • Today there are 6.7 billion people walking the Earth
  • In 50 years, there could be 9 billion

More to think about:

  • 200 years ago, forests covered about 40 percent of the planet's land mass
  • Today we are closing in on 20 percent coverage, losing close to 1 percent per year

 And some more:

  • Species loss today is about 1,000 times greater than the Earth's background level
  • In 1950, no fish stocks had collapsed
  • Today, 30 percent of fish stocks are unharvestable
  • Before 2050, all fish stocks may be collapsed

 And even more:

  • In the past 100 years, sea levels have risen 4.33 inches -- for which natural process cannot account
  • By 2100, that change could amount to more than 20 inches
  • The world's temperature has risen 1.1 deg C (2 deg F) since 1900
  • Average temperatures may climb by to 1.9 deg C (3.5 deg F)

A dark matter hurricane is crashing into Earth

Giving our solar system a "slap in the face."

Surprising Science
  • A stream of galactic debris is hurtling at us, pulling dark matter along with it
  • It's traveling so quickly it's been described as a hurricane of dark matter
  • Scientists are excited to set their particle detectors at the onslffaught

We are heading for a New Cretaceous, not for a new normal

The climate change we're witnessing is more dramatic than we might think.

Surprising Science

A lazy buzz phrase – 'Is this the new normal?' – has been doing the rounds as extreme climate events have been piling up over the past year. To which the riposte should be: it's worse than that – we're on the road to even more frequent, more extreme events than we saw this year.

New study reveals what time we burn the most calories

Once again, our circadian rhythm points the way.

Surprising Science
  • Seven individuals were locked inside a windowless, internetless room for 37 days.
  • While at rest, they burned 130 more calories at 5 p.m. than at 5 a.m.
  • Morning time again shown not to be the best time to eat.
