climate change

We Americans are heavy consumers of meat, and we're increasingly reminded that eating less of it will shrink our carbon footprint. Growing the crops to feed all those animals releases lots of greenhouse gases.

We often talk about climate change as a matter of science. But the biggest questions are really about money. How much would it cost to fix the problem — and what price will we pay if we don't?

The man who invented the field of climate economics 40 years ago says there's actually a straightforward way to solve the problem. William Nordhaus has written a book that lays it out in simple terms.

In 2008, as scientists documented a record melt in the Arctic ice and Al Gore's film An Inconvenient Truth was in theaters, a half dozen major investment houses launched mutual funds designed to take advantage of financial opportunities offered by climate change.

Florida — especially South Florida — is very flat and very low, and in places like Miami Beach and Key West, buildings are just 3 feet above sea level. Scientists now say there may be a 3-foot rise in the world's oceans by the end of the century.

In the summer of 2012, a small group of the Haida people, a native community in Canada, had a problem. The salmon they rely on were disappearing. So the Haida took matters into their own hands.

They partnered with an American businessman, drew up plans and then took a boat full of iron dust into the waters off their home island and put the dust in the ocean.

When they spread the iron dust, it created a big algae bloom. They hoped the algae would soak up carbon dioxide and bring back the fish.

Scientists and government representatives are meeting in Stockholm this week to produce the latest high-level review of climate change. It's thousands of pages of material, and if it's done right, it should harbor very few surprises.

That's because it's supposed to compile what scientists know — and what they don't — about climate change. And that's left some scientists to wonder whether these intensive reviews are still the best way to go.

The clang of tide gauges throughout parts of southeast Louisiana aren’t from a science fiction movie, though they may make residents feel like they’re caught in one.
