Climate Panel Stunner: Avoiding Climate Catastrophe Is Super Cheap But Only If We Act Now
By Joe Romm
The U.N. Intergovernmental Panel on Climate Change (IPCC) has just issued its third of four planned reports. This one is on mitigation human intervention to reduce the sources or enhance the sinks of greenhouse gases.
The first two reports laid out humanitys choice as depicted in the figure above, which appeared in both reports. The first report warned that continued inaction would lead to 9°F warming (or higher) for most of the U.S. and Northern Hemisphere landmass, resulting in faster sea level rise, more extreme weather, and collapse of the permafrost sink, which would further accelerate warming. The second report warned that this in turn would lead to a breakdown of food systems, more violent conflicts, and ultimately threaten to make some currently habited and arable land virtually unlivable for parts of the year.
Now you might think it would be a no-brainer that humanity would be willing to pay a very high cost to avoid such catastrophes and achieve the low emission 2°C (3.6°F) pathway in the left figure above (RCP2.6 which is a total greenhouse gas level in 2100 equivalent to roughly 450 parts per million of CO2). But the third report finds that the cost of doing so is to reduce the median annual growth of consumption over this century by a mere 0.06%.
You read that right, the annual growth loss to preserve a livable climate is 0.06% and thats relative to annualized consumption growth in the baseline that is between 1.6% and 3% per year. So were talking annual growth of, say 2.24% rather than 2.30% to save billions and billions of people from needless suffering for decades if not centuries. As always, every word of the report was signed off on by every major government in the world.

Release of Intergovernmental Panel on Climate Change Working Group 3 Report
Press Statement
John Kerry
Secretary of State
Washington, DC
April 13, 2014
Weve already had wake-up call after wake-up call about climate science. This report is a wake-up call about global economic opportunity we can seize today as we lead on climate change.
So many of the technologies that will help us fight climate change are far cheaper, more readily available, and better performing than they were when the last IPCC assessment was released less than a decade ago. Good energy solutions are climate solutions and this report shines a light on energy technologies available right now to substantially reduce global emissions.
These technologies can cut carbon pollution while growing economic opportunity at the same time. The global energy market represents a $6 trillion opportunity, with 6 billion users around the world. By 2035, investment in the energy sector is expected to reach nearly $17 trillion.
We already know that climate science is unambiguous and that every year the world defers action, the costs only grow. But focusing only on grim realities misses promising realities staring us right in the face.
This report makes very clear we face an issue of global willpower, not capacity.

isn't that.. SCIENCE ! And science just can't be trusted...
I have to say I really appreciate the time you and a number of other DUers take to research topics of interest and post them here.
I NEVER, EVER watch TV news... and, my 'research', study time is spent elsewhere. Plus a few drops of laziness. So I rely on work like yours.
