We’re Kidding Ourselves on 2-Degree Global Warming Limit: Experts

A temperature rise that could cause irreversible and potentially catastrophic damage to human civilization is practically inevitable, according to rising chatter among experts in the lead up to a year of key negotiations on a new climate change global accord.

World leaders have voluntarily committed to limit warming by the end of the century to 2 degrees Celsius (3.6 degrees Fahrenheit) above the pre-industrial level, a threshold beyond which, scientists argue, severe drought, rising seas and supercharged storms as well as food and water security become routine challenges.

Given the world’s historic emissions combined with a continued reliance on fossil fuels to power humanity for the foreseeable future, limiting the increase to 2 degrees Celsius is all but impossible, according to David Victor, a professor of international relations and an expert on climate change policy at the University of California, San Diego.
