The Guardian reports: Three-quarters of known fossil fuel reserves must be kept in the ground if humanity is to avoid the worst effects of climate change, a group of leading scientists and economists have said in a statement timed to coincide with Earth Day.
The Earth League, which includes Nicholas Stern, the author of several influential reports on the economics of climate change; Hans Joachim Schellnhuber, a climate scientist and adviser to Angela Merkel; and the US economist Jeffrey Sachs, urged world leaders to follow up on their commitments to avoid dangerous global warming.
Spelling out what a global deal at the UN climate summit in Paris later this year should include, the group demanded governments adopt a goal of reducing economies’ carbon emissions to zero by mid-century, put a price on carbon and that the richest take the lead with the most aggressive cuts.
In its “Earth statement”, the group said that three-quarters of known fossil fuel reserves must be left in the ground if warming was not to breach a rise of 2C, the “safety limit” agreed to by governments. [Continue reading…]
The Earth Statement begins: 2015 is a critical year for humanity. Our civilization has never faced such existential risks as those associated with global warming, biodiversity erosion and resource depletion. Our societies have never had such an opportunity to advance prosperity and eradicate poverty. We have the choice to either finally embark on the journey towards sustainability or to stick to our current destructive “business-as-usual” pathway. Three times this year, world leaders will meet to set the course for decades to come. In July 2015, heads of state meet to discuss Financing for Development. In September 2015, the UN Sustainable Development Goals (SDGs) will be adopted. In December 2015, nations negotiate a new Global Climate Agreement. Decisions made in this single year will be the legacy of our generation. In particular, if we do not succeed in tackling climate change, the sustainable development goals, livelihoods in many parts of the world and the wellbeing of our close and distant kin will be threatened.
In 2015, a good climate future is still within reach. If we act boldly, we can safeguard human development. It is a moral obligation, and in our self-interest, to achieve deep decarbonization of the global economy via equitable effort sharing. This requires reaching a zero-carbon society by mid-century or shortly thereafter, thereby limiting global warming to below 2°C as agreed by all nations in 2010. This trajectory is not one of economic pain, but of economic opportunity, progress and inclusiveness. It is a chance too good to be missed. We have just embarked upon a journey of innovation, which can create a new generation of jobs and industries, whilst enhancing the resilience of communities and people around the world.
