The crisis in Haiti has been dominating the headlines since Tuesday's earthquake. Link TV has already given you some ideas of how you can help, and your help, particularly in the form of cash, is urgently needed by the aid agencies working to save lives in Haiti. Now, we've put together this list of some of the best sources for information and news on Haiti. Feel free to add more links to the comment section!

1. Democracy Now! on Link TV
Democracy Now! has been providing impressive coverage of the Haiti earthquake and its aftermath at democracynow.org (click here for broadcast times on Link TV). Today's show reveals a Haiti that is growing increasingly desperate for aid. DN! also looks at angles glossed over by the major media networks, such as the decades of U.S. policies that have contributed to Haiti's terrible poverty.

2. Twitter
The microblogging site Twitter is a natural source for real-time news on Haiti. You can search for all posts in the Twitter-sphere on Haiti, or avoid some noise by trying a Twitter list, such as the ones set up by the LA Times or CNN. You can also look back at Twitter posts from individuals -- like this feed from Christian missionary Troy Livesay -- to see a timeline of the disaster from the perspective of one individual.

3. NGOs
Relief NGOs such as Partners in Health and Direct Relief International have updates on the aid efforts in Haiti. See this blog post for more relief organizations on the ground, and to learn how you can help.

4. Boston.com's Big Picture with Photography from Various Sources
These are photos not for the faint-hearted, but they do convey the true horror in Haiti after the quake struck. Boston.com does a nice job with its photo essays as part of its "Big Picture" series.

5. Global Voices Online
Global Voices, an online network of bloggers around the world, has a webpage with special coverage of the Haiti disaster, including a list of Haiti-based bloggers covering the story.

6. The Miami Herald
Miami has a substantial Haitian population, and the Miami Herald is serving its local community well by providing information in Creole (which, along with French, is one of two official languages in Haiti). The Herald's "Haiti Connect" forum includes a gallery for photos of missing loved ones.

7. Ushahidi - "Crowdsourcing Crisis Information"
This open-source web platform aggregates data on Haiti to support the relief effort. The interface is a little tricky to follow, but it's a great use of the web, compiling user-generated incident reports from the ground including reports of missing persons, emergencies and other threats. The incident reports - such as "Collapsed School", "…Stuck Under Rubble" - will break your heart.

8. New York Times Interactive Map
This map is another great visualization from the New York Times' impressive interactive team, complete with photos and audio.

9. NewsTrust.net
The amount of news articles available on Haiti is overwhelming, but NewsTrust curates the best from the mainstream and independent media. You can weigh in on the quality of the news articles with a review of your own.

10. U.S. Geological Survey Podcast
If you're interested in the science behind this horrific natural disaster, check out this podcast with Michael Blanpied of the USGS Earthquake Hazards Program. Here's the official USGS report on the Haiti 7.0 magnitude quake.

It's only day three of negotiations at the UN Climate Change Conference in Copenhagen, and the climate change roller coaster is quickly gaining momentum, with new urgency to release a draft climate agreement before the weekend. On Monday, the U.S. took strides towards regulating emissions when the Environmental Protection Agency announced the dangers of greenhouse gases on human health -- an important step towards setting tougher national emissions standards. But shortly thereafter, the U.S. and others took a hit with the leak of the "Danish Text", a controversial proposal by several parties, such as Denmark, the U.S., and the U.K., that attempts to give regulatory control to rich nations instead of the UN in setting international emissions standards, and drastically reduces CO2 targets for rich countries. This has no doubt infuriated many developing countries who are seeking to hold these very countries accountable for the emissions they produce.

Africa, for example, is demanding reparations for the devastating impact of heavy-emitting countries on their continent's natural resources and environment. Learn more about this from the latest episode of Link's Global Pulse, Africa: Cash for Climate Change?, and then have your say on whether or not you agree. Also, we hear so much about the melting glaciers of the Arctic, but we rarely hear about the lives of the people there, and how they are being impacted by rising temperatures and changes to the environment. This week, Link TV is airing explore: Arctic - Change at the Top of the World for a look at one of the most fragile and remote parts of the world.

Watch more about the effects of global warming on developing countries on Link's Climate Change Video page. One video from the remote Republic of Kiribati, while dated by its title, holds particular relevance due to the emotional presence of tiny island nations making their plea during negotiations this week.

To follow along with the events of the summit in Copenhagen, don't forget to tune in LIVE with Copenhagen 24/7, Link's continuous streaming video of the conference. Get by-the-minute updates through interviews, press conferences, and full coverage of the protests and actions taken on site. Join the live chat, too!

Today, with the start of climate negotiations in Copehagen, Link TV has teamed up with OneClimate.net and Justin.tv to launch the pioneering Copenhagen 24/7, a live webstream of breaking news, press conferences, and pre-recorded crowd-sourced video, straight from the frontlines of the summit. Follow summit events as they unfold and participate in a live chat with the millions of other viewers expected to tune in December 7-19, 2009.

While up to 200 global leaders, officials, and ministers are expected to participate in the historic negotiations to determine parameters of the next phase of the Kyoto Protocol, many are skeptical that parties will actually be able to deliver a comprehensive international agreement, and protestors have already begun to mobilize. Many developing nations have even stated that they are prepared to walk out of negotiations if fair and binding terms, that address their needs specifically, are not reached. Adaptation funding, clean technology transfer, and emission reduction targets are just a few of the issues that will undoubtedly present challenges for both developed and developing countries to consent on.

Midway through negotiations, on December 12th, people all over the world will be taking action to ensure participating parties heading into the final days of negotiations are prepared to deliver a real deal that safeguards the future of citizens worldwide.

So be sure to tune in to Copenhagen 24/7 to follow these exciting events, and up-to-the-minute news straight from the source. And follow Link's Action Alerts on Twitter for more updates on Climate Change, and to find out what you can do!
