Two degrees of climate change may be too much > http://thebulletin.org/two-degrees-climate-change-may-be-too-much8731 > Touring Alaska this week to shine a spotlight on global warming, > President Obama warned that “climate change is no longer some far-off > problem. It is happening here; it is happening now. Climate change is > already disrupting our agriculture and ecosystems, our water and food > supplies, our energy, our infrastructure, human health, human safety. > Now. Today.” > > This wasn’t supposed to happen. In 2009, 114 countries signed the > Copenhagen Accord, agreeing “to stabilize greenhouse gas > concentration in the atmosphere at a level that would prevent > dangerous anthropogenic interference with the climate system;” > “recognizing the scientific view” that the increase in global > temperature should be held to no more than 2 degrees Celsius” (3.6 > degrees Fahrenheit) above the pre-industrial level; and promising > greater “long-term cooperative action to combat climate change.” > > Paradoxically, an accord that should have spurred the world to > immediate action instead seemed to offer some breathing room. Two > degrees was meant to be a ceiling, but repeated references to an > internationally agreed-upon “threshold” led many people to believe > that nothing really bad could happen below 2 degrees—or worse yet, > that the number itself was negotiable. Perhaps the biggest failure of > the Copenhagen Accord was its pact for “long-term” action. Forty > years ago, climate change was a “long-term” problem. Today it’s an > emergency. > > Today we’re only about halfway to the 2-degree mark, yet the climate > is already haywire. Numbers such as 2 degrees and 350 parts per > million (or ppm, which many climate activists have identified as a > “safe” level for carbon dioxide in the atmosphere) have become > enshrined in the climate debate. Meanwhile, though, civilization’s > industrial machinery marches on. We’re already at 400 ppm of carbon > dioxide, and it looks like we will blow by 2 degrees, too. > > Such numbers may mean little to the general public, but they matter a > lot to negotiators who will be at Paris climate change talks in > December. Unfortunately, the numbers that these negotiators plan to > propose will only be part of non-legally-binding pledges—and they > represent only what is achievable without too much difficulty, rather > than the drastic austerity measures needed to stabilize emissions.

The very idea that the Paris > conference is a negotiation is ridiculous.
