NEGOTIATIONS:

Climate plans from 'non-state actors' hold great promise, but often lack substance -- study

When U.N. Secretary-General Ban Ki-moon convened world leaders in New York on climate change last year and called for ambition from boardrooms to state legislatures, hundreds of CEOs, mayors, governors and civil society heads signed voluntary pledges to tackle global warming.

Now a new study in Nature Climate Change finds that just five of the 29 action plans signed at the summit include explicit new mitigation pledges that can be tracked.

SCIENCE:

World can limit temperature rise to 1.5 degrees, but needs to act fast -- study

As researchers debate whether it is still feasible to stay within 2 degrees Celsius of global warming over preindustrial levels, a new study declares it is possible to keep the world even cooler.

The report published in Nature Climate Change today finds that keeping below a 1.5-degree temperature rise -- where island nations and other vulnerable communities say the world must get to in order to protect their existence -- can happen. But, the authors maintain, doing so will take rapid and immediate action on energy efficiency and the removal of carbon dioxide from the atmosphere.

Gov. Brown signs sweeping climate agreement with 11 international governments

California Gov. Jerry Brown (D) yesterday announced a pact with a dozen subnational governments from around the world, aimed at spurring ambitious climate commitments at upcoming U.N. negotiations.

Officials from regional governments in Brazil, Canada, Germany, Mexico, Spain, the United Kingdom and the United States signed an agreement in Sacramento limiting their greenhouse gas emissions by 2050 to levels that scientists say would stave off catastrophic climate change.
