Good morning, and welcome back to The Griddle, a morning menu of fortified items for the busy person's media diet. In 1958, a scientist named C. David Keeling started monitoring the carbon dioxide content of the atmosphere, which was then about 314 ppm, or parts CO2 per million parts of air. Within two years, Keeling could tell it was trending up. The National Oceanic and Atmospheric Administration maintains this data set, known as the "Keeling Curve," to this day.
This morning, the World Meteorological Organization issued its annual Greenhouse Gas Bulletin, which measures levels of heat-trapping gases driving climate change. The WMO reports that 2010 set a new CO2 record, of 389 ppm, indicating a rebound in the global economy and a harbinger of the challenges ahead. And now, more news:Read more »
Good morning, and welcome back to The Griddle, a morning menu of fortified items for the busy person's media diet. Some state officials think the EPA's oversight of natural gas extraction from shale (aka hydraulic fracturing, aka fracking, aka fraccing) is better left to the states. “Fracking has never been regulated by the federal government,” Michael Krancer, secretary of Pennsylvania's environmental agency, told Bloomberg News. “This is a philosophic question that goes back to 1789.” See first opinions here by early blogger James Madison.

The UN Intergovernmental Panel on Climate Change whirrs into action this week with a significant assessment of extreme events and disasters. The final report is due on Nov. 18. A draft summary for policymakers obtained by Bloomberg shows the caution and rigor with which scientists approach attributing observed trends to man-made climate change.
The panel says it's “virtually certain” that warm daily temperature extremes will increase in this century. It’s "likely" that human influences have led to a warming of extreme daily minimum and maximum temperatures across the globe, and that instances of heavy rainfall will increase. The report finds the average maximum wind speed of hurricanes is likely to increase, though storm frequency is likely to drop or remain the same.Read more »
Good morning, and welcome back to The Griddle, a morning menu of fortified items for the busy person's media diet. Coffee futures rose the most in three weeks yesterday on higher anticipated demand in the U.S. We can't help but wonder how much of that is our fault, as we gear up for the launch of our new Sustainability page on Bloomberg.com. We'll have more news to share in the next few weeks.

Good morning, and welcome to The Griddle, a morning menu of fortified items for the busy person's media diet. With Bangkok under water and Occupy Wall Street under arrest, the quote of the day comes from SmartPlanet columnist John Rennie: “Global warming’s connection to extreme weather events has always been as diffuse as the economy’s tie to unemployment. The difference is that no one has tried to pretend that the economy is irrelevant."

The cost of solar cells and microchips has nowhere to go but down because of a supply glut for the commodity they’re made from, a brittle charcoal-colored semiconductor baked in ovens at 600 degrees centigrade.
Polysilicon has plunged 93 percent to $33 a kilogram from $475 three years ago as the top five producers more than doubled output, data compiled by Bloomberg shows. The industry next year will produce 28 percent more of the raw material than will be consumed, up from 20 percent this year, said Robert Schramm-Fuchs and Shai Hill, analysts at Macquarie Group Ltd.Read more »
