Cattle graze at a Brazilian Agricultural Research experimental farm in Planaltina in Goias state. To reduce emissions from deforestation, the Brazilian government is experimenting with grazing on integrated forest and pasture lands.

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.
The jet stream that circles Earth's north pole travels west to east. But when the jet stream interacts with a Rossby wave, as shown here, the winds can wander far north and south, bringing frigid air to normally mild southern states.
Parker Liautaud, 19, is a sophomore at Yale University studying geology and geophysics. He’s also a polar adventurer who just returned from an expedition, where he and another explorer broke the world record for the fastest unsupported trek from the coast of Antarctica to the South Pole.
Former East Haven police Officer Dennis Spaulding was sentenced on Thursday to five years in federal prison for federal civil rights violations. Spaulding was convicted October 21 of every charge brought by government prosecutors. That includes conspiracy to violate civil rights, deprivation of rights for making arrests without probable cause, obstruction of justice and use of unreasonable force. He faced a maximum sentence of 20 years.
Puddled meltwater very likely primed this ancient edge of the Antarctic's Larsen Ice Shelf to rapidly disintegrate over just several weeks. This view of the splintered mix of frozen bergs is from a Feb. 21, 2002, satellite image.
An expert panel at the National Academy of Sciences is calling for an early warning system to alert us to abrupt and potentially catastrophic events triggered by climate change.
The committee says science can anticipate some major changes to the Earth that could affect everything from agriculture to sea level. But we aren't doing enough to look for those changes and anticipate their impacts.
What can religion say about climate change? It turns out a lot. Take for example, the Old Testament story of Noah and the flood. You remember how it goes: people behaving badly, Noah building an ark, God sending a flood, and, eventually, a Rainbow covenant formed between God and man. Except, said Terri Eickel, the covenant was larger than that.
There was an internal debate about including a link about a local meteorologist and cat vomit. We passed. If you'd like to see that, you can search it out on your own because we've already said too much. Speaking of cat vomit, CNN informs us that we are in Day Ten of the federal government shutdown, and the debt ceiling deadline is 156 hours away as this is written. That means you have time to watch all of "Battlestar Galactica," "Breaking Bad," and the first seven seasons of "Seinfeld" before the deadline. Hop to it.
If I were to tell you a story about the long-term outlook for the world -- our people, our resources, our air, water and food -- and what we should do about it, you might expect that the story would start with climate change. It has become the lead issue of the environmental movement, and according to many, the most important issue of our time.
Biologist Paul Ehrlich became famous in the 1970s with his book The Population Bomb, which outlined a doomsday scenario in which the world’s supply of food and resources couldn't keep up with overpopulation.
Russian prosecutors have filed charges of piracy against 14 people who were aboard a Greenpeace boat during a protest last month in the Russian Arctic. Under Russian law, piracy is punishable by as much as 15 years in prison. Greenpeace says it was peacefully protesting the dangers of oil drilling in the Arctic and that the Russian government is violating international law.
On the first Monday of the rest of your life, it's MORNING EDITION from NPR News. I'm Steve Inskeep.
DAVID GREENE, HOST:
And I'm David Greene. Climate change is melting ice in the Arctic. And that is opening up the top of the world to drilling, shipping traffic, and also concerns about the environment. Earlier this month, Greenpeace activists were arrested trying to board an oil platform that's owned by Russia's state gas company.

Declaring that "human influence on the climate system is clear," a U.N.-assembled panel of scientists reported Friday that "it is extremely likely that human influence has been the dominant cause of the observed warming since the mid-20th century."
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.
From the standpoint of global warming, burning natural gas can be better than burning coal, a study published this week suggests.
This is a contentious issue among people who are opposed to the natural gas drilling practice known as fracking. That technique involves injecting water, sand and chemicals into wells to release far more gas than conventional drilling can. Opponents of fracking have been concerned not only about local environmental issues, but also about the potential for methane leaks to make global warming worse.

Scientists watching Antarctica's Pine Island Glacier from space have noticed with some alarm that it has been surging toward the sea.
If it were to melt entirely, global sea levels would rise by several feet.
The glacier is really, really remote. It's 1,800 miles from McMurdo, the U.S. base station in Antarctica, so just getting there is a challenge. Scientists have rarely been able to get out to the glacier to make direct measurements.
We’ve talked about warming waters before on Where We Live. Now warm waters are in the news again. There are new climate change studies that provide more proof of the human causes of warming temperatures. The next big UN report on climate change contains some scary predictions...that sea levels could rise more than three feet by the end of the century.
In a leaked climate report, the Intergovernmental Panel on Climate Change (IPCC) — a United Nations scientific body that makes definitive assessments on climate change — has determined with 95 percent certainty that humans are responsible for global warming.
The report also increased its estimate for sea level rise, as a result of the warming planet.
The final report is due to come out in September. A draft was leaked over the weekend.
The weather is one of those topics that is fairly easy for people to agree on. Climate, however, is something else.
Most of the scientists who study the Earth say our climate is changing and humans are part of what's making that happen. But to a lot of nonscientists it's still murky. This week, two of the nation's most venerable scientific institutions tried to explain it better.
The state's first microgrid projects have been announced. Nine projects in eight communities have been approved as part of a microgrid pilot project - the first in the nation - conceived after Tropical Storm Irene and the October snowstorm in 2011 left large swaths of the state without power for more than a week.
Anthony Leiserowitz, director of the Yale Project on Climate Change Communication addressed a crowd that included U.S. Sen. Richard Blumenthal in a town hall-style meeting on climate change. The event was held on March 27 at Yale.
