Congratulations, my fellow anatomically modern human. Most especially, those of you who played Sgt. Schultz on a global scale and saw nothing—abs-o-lute-ly nothing!—as temperatures increased, ocean currents shifted, and ice melted. Paleoclimatologist Michael Mann summed up the news about West Antarctica. "This is yet another example of how uncertainty is not our friend when it comes to human-caused climate change. Here once again mother nature is ahead of schedule relative to our best model forecasts. ... There is still a good chance, however, that we can prevent even larger contributions to ice melt and sea level rise (e.g. the melting of the Greenland Ice Sheet), if we reduce carbon emissions substantially over the next decade." Mann added, "But make no mistake, this is a reminder of the urgency now of acting to avoid dangerous and potentially irreversible climate change."

The pristine skeleton of a teenaged girl who lived about 13,000 years ago, discovered in a deep, water-filled underground cavern in the sprawling a cave system in Mexico's Yucatan Peninsula, is providing archeologists with an unprecedented glimpse into the history of the early inhabitants of the Americas.

More Tagging tips:

A tag is a way to search for this diary. If someone is searching for "Barack Obama," is this a diary they'd be trying to find?

Use a person's full name, without any title. Senator Obama may become President Obama, and Michelle Obama might run for office.

If your diary covers an election or elected official, use election tags, which are generally the state abbreviation followed by the office. CA-01 is the first district House seat. CA-Sen covers both senate races. NY-GOV covers the New York governor's race.

Tags do not compound: that is, "education reform" is a completely different tag from "education". A tag like "reform" alone is probably not meaningful.

Consider if one or more of these tags fits your diary: Civil Rights, Community, Congress, Culture, Economy, Education, Elections, Energy, Environment, Health Care, International, Labor, Law, Media, Meta, National Security, Science, Transportation, or White House. If your diary is specific to a state, consider adding the state (California, Texas, etc). Keep in mind, though, that there are many wonderful and important diaries that don't fit in any of these tags. Don't worry if yours doesn't.
