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.

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.

In a season of a high-profile Supreme Court nomination, economic stimulus, and early health care negotiations, why are we hearing so little about the Obama administration's environmental and energy policy?

The answer may lie in Obama's use of terms like "clean coal," "carbon capture and storage," and "cap and trade" that imply more a gesture of environmentalism rather than a full-scale energy revolution. In recent weeks, Obama has deferred to House Democrats to craft a climate change bill that creates the first carbon emissions trading system loosely modeled on EU energy policy. The plan though, in giving away 85% of carbon trade permits to industry for free, sets far more modest goals than the EU system for reducing carbon emissions.

Obama has been even more quiet about a $2.4 billion rollout this month of "clean coal" investments designed to reduce the environmental impact of coal-powered energy. Environmentalists like Al Gore mock the very idea of clean coal power, but similar programs are being implemented in the EU and China as economic stimulus measures.

Even as energy policy takes a back-seat to other administration priorities, there is still pressure to move quickly on new programs. Obama has promised to raise substantial revenue from carbon emissions trading to help pay for expenses like universal health care. Also, there is hope that Obama will sign on to global energy standards this December in Copenhagen to succeed the Kyoto Protocol, which previous U.S. administrations never implemented.
