The demand for answers continues as world climate-change leaders gather in Copenhagen for a summit on climate change.

On Monday, the EPA released a statement saying greenhouse gas emissions pose a threat to public health and welfare.

But a new CNN poll finds that while most Americans believe that global warming is a proven fact, the number who think that climate change is due to man-made emissions has fallen below 50%. We want to hear your views on global warming.

Post your iReport video responses and we'll show some during CNN Newsroom.

Evelyn and Andreas Preuss at the Berlin Wall, April 1990

Lots of memories today of the Berlin Wall falling. My mother, who is from Berlin, and I went there to participate in the event.

Read my CNN.com blog entry here: http://inthefield.blogs.cnn.com/2009/11/06/walls-shadow-fell-across-generations/

I talked with Josh Levs in the CNN Newsroom about our Wall experience. Check out the clip below.

Organizers call it "the most widespread day of environmental action in the planet's history." Today, in 181 countries and all 50 U.S. states, people are taking part in an event organized by 350.org.
The goal, the group says, is to bring attention to the need to lower carbon levels. In the Newsroom, we're explaining what the "350" means.

To Vaccinate or Not: Some Wary on H1N1 Choice

Many parents are discussing their skepticism of the H1N1 vaccine. It's being distributed as a nasal spray this week, and will arrive next week in injection form, according to the Centers for Disease Control and Prevention.

Two key issues for skeptics are the safety of vaccine and their own vulnerability.

The CDC and other public health authorities say the new vaccine is safe. It is encouraging everyone to get it, especially those in high risk groups. But experts acknowledge that many people struggle with the decision.

Are you going to get the vaccine or let your child get it? Post your comments below. We may use some of them this morning in the CNN Newsroom.

Some friends have sent their pictures of the flooding in and around Atlanta. We didn't get to use them on the air, so I thought I'd post them here as Kyra Blog Exclusives.

CNNer Dave J has a 25-mile commute home. It took a good bit longer than usual to get there Monday afternoon.

In his words:

First of many roads I encountered like this on my way home. Commute time: 2 hrs. 50 min.

My "commute" is only 2 miles or so; even so, there were unexpected obstacles. Monday after work, I turned the corner and splashed into one. Lucky my car's got good clearance!

Here's a pic my neighbor took, and sent to the AJC. (As of this morning, the tunnel was still impassable.)
