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.
