Something most of us are not aware of: An amazing amount of trash is dumped into the ocean. It comes from landfills and from cruise ships that throw their trash directly into the sea. The ocean is becoming more and more acidic, and a surprising amount of debris is being dumped in space too.

Outer space security has become an increasingly important problem recent years, since derelict satellites and parts that “got away” when they were being repaired are orbiting the earth. We need to pass some international laws to avoid collisions with space trash!

Ocean levels could rise by as much as 5 feet in the next 100 years, drowning major coastal cities all over the world. This is much more than the Intergovernmental Panel on Climate Change (IPCC) forecasted a year ago and could mean the end of island nations and low-lying countries such as Bangladesh, where 80 to 90% of the population lives within a few feet of sea level.

In BBC News, Richard Black reports quotes climatologist Svetlana Jevrejeva as saying, “The rapid rise in the coming years is associated with the rapid melting of ice sheets.”

We count on the ocean to act as a “carbon sink,” sucking much of the carbon dioxide out of the atmosphere. Without this, global warming would be progressing much more quickly. But now scientists say that the amount of carbon dioxide being absorbed by the world’s oceans has diminished.

BBC News reports that “scientists believe global warming might get worse if the oceans soak up less of the greenhouse gas,” and quotes environmentalist Roger Harrabin as saying, “The researchers don’t know if the change is due to climate change or to natural variations. But they say it is a tremendous surprise and very worrying because there were grounds for believing that in time the ocean might become ‘saturated’ with our emissions?unable to soak up any more.”
