The Grudge Match: Republicans vs. Science

In this handout photo, taken in 2011, provided by Jonathan Gero, scientists witness and measured carbon dioxide trapping heat in the sky above, confirming human-caused global warming, using the Atmospheric Emitted Radience Interferometer seen here, located in Barrow, Alaska.  Scientists witnessed carbon dioxide trapping heat in the atmosphere above the United States, chronicling human-made climate change in action live in the wild.  A new study in the journal Nature demonstrates in real-time field measurements what scientists already knew from basic physics, lab tests, numerous simulations, temperature records and dozens of other climactic indicators.  It confirms the science of climate change and the amount of heat-trapping previously blamed on carbon dioxide.  (AP Photo/Jonathan Gero, University of Wisconsin)

There are so many ways to go about this. We might, for instance, pause to consider the pathetic canard about how the competing political parties in these United States are the same. Or perhaps we could take a moment to think about why American progress lurches forward in quick bursts after seeming to stall for extended periods. And it is not exactly impossible that we might also eventually encounter an opportunity to simply look away and give our attention to something else.

First up, science:

Scientists training their instruments on the skies have caught the world’s major greenhouse gas right in the act of warming the planet, researchers reported Wednesday, providing the first direct evidence that human activity is dangerously altering the environment.

The instruments captured more than a decade of rising surface temperatures, changes that were directly triggered by the atmosphere’s increasing burden of carbon dioxide, a team of scientists from Lawrence Berkeley National Laboratory and University of California, Berkeley, reported.

That gas, whose main source is emissions from burning fossil fuels, has long been the principal culprit in global-warming investigations by the vast majority of the world’s climate scientists. Its rising levels in the atmosphere have been the basis for increasingly strong warnings about global warming by the Intergovernmental Panel on Climate Change, known as the IPCC.

“We have known for decades that there must be an effect, but getting a direct measurement and isolating the carbon dioxide component are a technological coup,” Christopher Field, a senior scientist at the Carnegie Institution for Science at Stanford University who has led two major IPCC reports, said in an email.

The UC Berkeley scientists’ study, he said, provides concrete evidence for the first time of carbon dioxide’s effect on global warming.
