Coca-Cola has one of the most recognizable brands on the planet: the red can with the white letters. World Wildlife Fund has an equally eye-catching logo: a black-and-white panda. This week, the two are joining forces to change the Coke can’s look from red to white. It’s meant to raise awareness and money to find a safe haven for polar bears, listed as a threatened species because their icy Arctic habitat is melting under their paws due to climate change.
Amid the worry about water and food scarcity, some hints of good news: a five-year, 30-nation analysis suggests there might be enough water — and therefore enough food — for Earth’s hungriest and thirstiest as the human population heads toward the 9 billion mark sometime around mid-century.
For years, climate scientists were circumspect when asked if a specific bit of violent weather — for example, Hurricane Irene, the late-summer storm that slammed the heavily populated U.S. East Coast — could be blamed in some way on climate change.
A word has entered the language — at least, the language of environmental concern — that may be ready for prime-time. That word is Anthropocene. It’s the epoch we’re apparently living in, roughly translated as the Age of Man. The theory behind the name is that human beings have made such an impact on Earth’s geology that we should have an era named for us that differentiates this time from the tired old Holocene period.
Climate doesn’t change by magic.
Just ask Mark Serreze, director of the U.S. National Snow and Ice Data Center in Colorado. On a conference call with other scientists and reporters, Serreze and others linked climate change to the last two harsh winters over much of the United States and Europe. And they squarely blamed human-caused greenhouse gas emissions for the rise in world temperatures that got the process going.
Another winter storm is brewing in Middle America. So what else is new?
It’s been one spate of severe weather after another even before 2011 began. And you would expect those skeptical of climate change to capitalize on the cold snap by questioning whether human-spurred global warming is a real deal.
The Chinese flags have disappeared from Washington’s wide avenues after China’s President Hu Jintao’s visit this week, but one statistic is still in the air: the rapidly expanding size of the Chinese ecological footprint, compared to the huge but slowing impact U.S. consumers have on global supplies of food, water, fuel — everything, really.
Greenland’s ice sheet melted at a record rate in 2010, and this could be a major contributor to sea level rise in coming decades.
