Global Warming or Climate Change

Climate change scientist James Hansen says current ‘half arsed’ plans to reduce emissions will lead to dangerous climate change and calls for an honest carbon price to cut fossil fuel use  Former head of Nasa’s Goddard Center James Hansen says the UN meeting is on the wrong track by seeking a 2C maximum rise in temperatures.

(AP Photo/Francois Mori) LE BOURGET, France - The latest news from the U.N. climate conference in Paris, which runs through Dec. 11. All times local: 7:45 p.m. Researchers say a simulation has showed that it is "technically possible" to reach a climate deal and succeed in limiting global warming. Climate Interactive, a research group that models the effects of cutting emissions, took their models to the Paris climate talks Friday and invited regular people to role play, with MIT professor John Sterman as the United Nations chief. Following the first round of negotiations, national pledges left global warming temperatures unaffected as no team was ready to compromise. After more than an hour of arguments over w...

orld leaders have gathered in Paris to try to hammer out a plan to slow the machinery of climate change. They are guided by scientists who know which gauges to monitor. Here’s how experts say these pieces fit together.
