States, Nations Announce Commitments Ahead of U.N. Climate Conference

Roughly six months before international leaders meet in Paris for a United Nations climate change conference, U.S. states and foreign nations are stepping forward with climate commitments. Canada, on Friday, pledged to cut its greenhouse gas emissions 30 percent below 2005 levels by 2030.

California is joining a climate agreement with eight foreign nations and four states that aims to keep the world’s average temperature from rising another 2 degrees Celsius. All signatories of the Under 2 MOU commit to either reduce greenhouse gas emissions 80 to 95 percent below 1990 levels by 2050 or achieve a per capita annual emissions target of less than 2 metric tons by 2050.

“This global challenge requires bold action on the part of governments everywhere,” said California Gov. Jerry Brown, who urged Under 2 MOU to serve as a template for Paris. “It’s time to be decisive. It’s time to act.”

The signatories of the non-binding agreement include: California; Vermont; Oregon; Washington; Wales, United Kingdom; Acre, Brazil; Baden-Württemberg, Germany; Baja California, Mexico; Catalonia, Spain; Jalisco, Mexico; British Columbia, Canada; and Ontario, Canada.

India and China—among the world’s largest emitters of greenhouse gases—also committed to working together in advance of Paris negotiations. Neither made formal commitments, indicating they would submit their official plans “as early as possible” and “well before” the December conference. In a statement, both urged “developed countries to raise their pre-2020 emission reduction targets and honor their commitment to provide $100 billion per year by 2020 to developing countries.”

Studies Examine Cause of Warming

A study published in Environmental Research Letters presents a 1958–2012 temperature and wind dataset of the upper troposphere (Earth’s atmosphere) as clear evidence of emissions-induced climate change.
