The car alarms. The garbage trucks. The straphangers who crowd the doors on the subway and then lean into you as you try to squeeze past them.

Ah, it's good to be back in New York. At least when it's warm.

I just spent a few days in Greenland for our "Planet in Peril" series. We were at a place called Swiss Camp, it's a research outpost run by a scientist named Konrad Steffen out of the University of Colorado.

A more remote spot I have not been to. Nothing but ice as far as the eye could see. We all slept in tents and the toilet was a hole in the ice in an igloo. They call it the shigloo. You can guess why.

It was stunningly beautiful there, and the researchers were a great bunch - wickedly smart, but also very funny. When it's ten below zero a sense of humor is essential. I have to confess, I'm not a big fan of the cold. How cold was it? It was so cold I didn't bother to change out of my clothes for the entire five day stay. I slept fully dressed in a sleeping bag, and I didn't even bother to brush my teeth the entire time.

The scientists are there for a month. I don't know how they stand it. By the time the helicopter came to pick us up I wanted to run towards it as fast as possible. Complaining aside, it was a great experience and I learned a lot about how the ice is melting in Greenland and how it is going to affect sea levels for generations to come. We're planning to have some of what we shot on the program tonight.

I just noticed that all three New York newspapers have different headlines splashed on the covers. The Daily News has the latest on Lindsay Lohan. The Post is running exclusive photos on a baseball player's visit to a strip club (catchy title: Stray-Rod). And the New York Times is exploring the Supreme Court's ruling that limits the timeline for sexual discrimination lawsuits.

As for us, we're looking at the tuberculosis quarantine story...there now seems to be a dispute over what the TB patient knew, about how contagious he is and really-- what was going on-- if his health posed such a threat why would he not have been quarantined in the first place? Lots of questions.

And as always we're "Keeping Them Honest." Our correspondent Drew Griffin is looking at Congress' seemingly insatiable need to bring home the bacon, (your tax dollars) in the secret process known as earmarking...even when they vow again and again to be transparent about the process. (Hint: Rep John Murtha, who has been in the news for his strong opposition to the White House on Iraq, will be at the center of one of tonight's reports)

There is always something for everyone.

See you tonight.
