We begin today in Denmark where week two of the UN Climate Conference is getting underway. One of the big goals of this meeting was to put together a deal to reduce greenhouse gas emissions. World leaders, including President Obama, are heading to Copenhagen later on this week to try to finalize the agreement. But some analysts have said there hasn't been much progress so far and there are some questions about how the deal would be paid for. Thousands of demonstrators in the streets of the Danish capital during the conference demanded that participants create a climate change agreement. Most of the protests have been peaceful. Some did turn violent. On Saturday, more than 900 demonstrators were detained by police. Nearly all of them were later released. Indonesian officials say a powerful earthquake off the coast of the island of Sumatra has killed 13 people. The quake destroyed many buildings and cut communications in and around the city of Padang. Residents say people are trapped in the rubble and some bridges have collapsed. The quake which had a magnitude of 7.6 was felt hundreds of kilometers away in Singapore and Malaysia. The Pacific Tsunami Warning Center had issued a tsunami alert minutes after the earthquake hit off the coast of west Sumatra but then lifted it. The tremor was felt as far away as Indonesia's capital city, Jakarta. There have been reports of buildings and houses collapsing in the city of Padang, Sumatra's capital, which is near the epicenter of the earthquake. Senators are considering alternatives to part of their health care legislation. Specifically, the so-called public option: government-run health insurance program. Senate republicans and some democrats and independents are against that plan. A group of Democratic Senators was working to come up with some other ideas they could replace the public option. And late last night, they said they had reached an agreement. If the Senate passes its health care bill, that does not make it law. It would still need to be combined with Health Bill, and then that final version would need to pass both the House and the Senate.
