A recent CBS News poll reveals 70 percent of American adults think global warming is an environmental problem having a serious impact now. That's up from 67 percent a year ago.

Snow pack, just miles from major metropolitan areas, not glaciers thousands of miles away, is melting too fast atop California's Sierra Nevada range, California scientists say. Less snow pack means less water for the nation's most populous state, where greater temperatures are putting pressure on drinking water and crop irrigation supplies.

The keepers of the Doomsday Clock, tracking the threat of nuclear war, moved the minute hand two minutes closer to midnight, not because someone got their hands on a suitcase nuke, but because of the potential for disaster from climate change.

Finally, treated like some secretly-held government, corporate or celebrity scandal, a major scientific global warming report was leaked to the media a week early with "smoking gun" implications that humans burning fossils fuels have caused the planet to get way too steamy.

In a matter of days, the global warming story has perhaps shaken off the last vestiges of its treatment as some contentious debate or political football to emerge as what's likely to become one of the leading stories, if not the leading story, for the next several decades.

That's largely because, where we live, from sea to rising sea, will increasingly take on grave new meaning. What it costs to buy, maintain, insure and sell homes in many areas will be at the mercy of global warming.

Most scientists say climate change already impacts our health, the availability of the food we eat and other species that share the planet.

"The report reconfirms that no matter what we do, we are in for (at least) another two degrees of warming in the next 45 to 50 years because so much (that causes global warming) is already in the pipeline," said ABC New's Bill Blakemore, who received a draft copy of the study.

The term global warming refers to an increase of the Earth's average temperature. Accelerated planetary warming in recent human history has been blamed for melting glaciers, shrinking ice caps, swelling oceans, stronger hurricanes, spreading drought, fiercer forest fires, harsher winters and the impact on life that comes with those conditions.

The leak indicates the Intergovernmental Panel on Climatic Change (IPCC) is purposely driving drama into "Climate Change 2007," a report that says, with 90 percent certainty, humans put themselves in really hot water.

"Scientists themselves have reached a level of frustration, not having heard from as many politicians about what they've been trying to tell us for a decade or more," said Blakemore, interviewed by the Weather Channel's senior climatologist Dr. Heidi Cullen who hosts the new Climate Code program on air and One Degree Climate Code website.

The media may also be at fault, say some critics of the coverage provided global warming. In it's well-meaning, fair-and-balanced over zealousness, the media has often given equal or more time to global warming naysayers, detractors and outright quacks claiming the world event is somehow politically motivated, simply a hoax or both.

The Weather Channel's unique Climate Code of both online and on air programming, less than a year old, is the first and only such programming dedicated solely to a regular, ongoing journalistic presentation of "an open, balanced dialogue around the scientific facts concerning global climate change."

Given the far reaching impact expected from the full IPCC report, hopefully, that will change.

On Feb. 2, after six years of work, 2,500 scientists representing 130 nations, will lay four volumes of scientific global warming research on the table.

That should heat up media coverage.
