Danish statistician Dr. Bjorn Lomborg, the President of the Copenhagen Consensus Center: 'We will spend at least one hundred trillion dollars in order to reduce the temperature by the end of the century by a grand total of three tenths of one degree...the equivalent of postponing warming by less than four years...Again, that is using the UN's own climate prediction model.'
'If the U.S. delivers for the whole century on the President Obama's very ambitious rhetoric, it would postpone global warming by about eight months at the end of the century.'
'But here is the biggest problem: These miniscule benefits do not come free -- quite the contrary. The cost of the UN Paris climate pact is likely to run 1 to 2 trillion dollars every year.'
Kerry stated, we must act quickly “to avoid the catastrophe we will inevitably see if we allow carbon emissions to go up, and up, and up.” Moreover, he added, “We need to speed it up dramatically because we are in a race against time.” ...“What we do right now, today, matters,” Kerry told the audience. “We don’t get a second chance on this one.”
Climatologist Dr. Judith Curry told E&E News in a Jan. 3 interview: 'The one thing we know is that the commitments we’ve made, in Paris, will probably prevent about two-tenths of a degree of warming by the end of the 21st century. What is the point?'
