Reuters: Governments can keep climate change in check at manageable costs but will have to cut greenhouse gas emissions to zero by 2100 to limit risks of irreversible damage, a U.N. report said on Sunday. The 40-page synthesis, summing up 5,000 pages of work by 800 scientists already published since September 2013, said global warming was now causing more heat extremes, downpours, acidifying the oceans and pushing up sea levels. "Science has spoken. There is no ambiguity in the message. Leaders must...

Agence France-Presse: Time is running out to limit global warming to two degrees Celsius (3.6 degrees Fahrenheit), the UN's climate experts warned Sunday, saying current carbon emissions were a potential path to disaster. Crowning a landmark review, the Intergovernmental Panel on Climate Change (IPCC) said emissions of three key greenhouse gases were at their highest since more than 800,000 years ago, when mammoths and mastodons roamed the earth. Earth, it warned, is on a likely trajectory for at least 4 C warming...

Bloomberg: A dispute about how to link greenhouse-gas emissions cuts to a promise from the wealthiest nations for $100 billion a year in climate aid emerged as a major stumbling block at UN talks on global warming. After a week of discussions that ended today in Bonn, envoys from some 190 nations were deadlocked about the formula countries will use to set out their commitments on reducing fossil-fuel pollution in time for the deal they plan to sign in Paris in 2015. That means higher-level officials will...

Yale Environment 360: Urban footprint of Tokyo The number of urban areas with more than 10 million inhabitants -- sometimes called "megacities" -- has nearly tripled in the last 24 years, jumping from 10 in 1990 to 28 in 2014, according to the latest UN report on world urbanization. The total number of people living in megacities has grown from 153 million to 453 million during that period, the report says, and such areas now account for 15 percent of global GDP. Many are located in Asia: Tokyo, Japan, now tops the list...

Mongabay: In 2011, Germany and the International Union for the Conservation of Nature launched the Bonn Challenge, which pledged to restore 150 million hectares of degraded and deforested lands by 2020. Several countries have already made commitments-including the U.S.-but this week at the UN Climate Summit four more jumped on board. The Democratic Republic of the Congo committed to restoring 8 million hectares, Uganda committed to 2.5 million hectares, and Guatemala committed to restoring 1.2 million hectares....
