"In the face of an absolutely unprecedented emergency,​ society has no choice  ​but to take dramatic action ​to avert a collapse of civilization."  Blue Planet Laureates UN Rio+20  2012.

Global warming threatens the very survival of humanity (UNEP GEO4). 

We are now committed to a number of catastrophic climate change ​impacts because of future degrees warming that can no longer ​be avoided.

James Hansen planetary emergency  2008  ​short VIDEO
In 2008 and again in 2012 James Hansen made a public statement warning that as a result of the rapid Arctic changes a planetary emergency existed.  In 2010 James Hansen's book Storms of My Grandchildren The Truth About the Coming Climate Catastrophe and Our Last Chance to Save Humanity explained the emergency in detail.

In  2009 Lester Brown, an American leading expert in sustainability published his Plan B 4 (Earth Policy Institute) Mobilizing to Save Civilization. ​​​His plan to deal with this unprecedented crisis is the most comprehensive there is.
Many authorities have warned that we are in a global climate change planetary emergency.
Planetary Emergency

​​The rapidly melting Arctic snow and summer sea ice
has already changed our world. Now the Global North is in a climate emergency  situation as well as the Global South, due to N. hemisphere climate instability, extreme summer heat and drought. This will first affect world food security and prices hurting billions of most vulnerable people in the world.
Many food producing regions  have  been affected by drought in the past few years. ​​

In addition a planetary emergency exists for all future life because the Arctic summer sea ice is past its tipping point (2007) and Arctic methane feedback ​​has started, which leads to rapid runaway global warming.

Since 2009 (following James Hansen's statement) this project has been documenting the increasing evidence that we all live in a state of global climate change planetary emergency.

Nov 2013 IPCC AR5 WG1 ​The warming of the planet since 1950 is “unprecedented,” ​
World Bank Turn Down the Heat reports 2013. The world is being committed to an end of the world 4C warming. A 2C world (the 2C target) is catastrophic for billions. ' ...​the science is clear. There can be no substitute for aggressive national mitigation targets, and the burden of emissions reductions lies with a few large economies.”
