UN scientists call for shift in energy sources in IPCC climate report
The latest report by the UN's climate change panel, released Sunday, calls for lowering global greenhouse gas emissions 40-70 percent by the end of the century.

The latest report by the UN's climate change panel, released Sunday, calls for lowering global greenhouse gas emissions 40-70 percent by the end of the century.

The world's scientists say time is running out to avert the most dire effects of climate change.

The latest report by the UN's climate change panel, released Sunday, calls for lowering global greenhouse gas emissions 40-70 percent by the end of the century. A big part of that is focusing on what energy sources we use and how much we consume.

For more, we're joined by Cara Horowitz, co-executive director at the Emmett Institute on Climate Change and the Environment at UCLA.

Some highlights of the report:

  • Global greenhouse gas emissions grew more quickly between 2000 and 2010 than in each of the three previous decades.
  • The goal of limiting the increase of the global mean temperature to 2 degrees Celsius above pre-industrial levels will depend on "institutional and technological change."
  • The report involved 235 authors from 57 countries; more than 800 experts reviewed drafts and submitted comments.
