Draft National Climate Assessment Finds Drastic Climate Change Impact on US 0817
     “Evidence for a changing climate abounds, from the top of the atmosphere to the depths of the oceans.”
     “Many lines of evidence demonstrate that human activities, especially emissions of greenhouse (heat-trapping) gases, are primarily responsible for recent observed climate change….  There are no alternative explanations, and no natural cycles are found in the observational record that can explain the observed changes in climate. (Very high confidence)
     “Even if humans immediately stopped emitting greenhouse gases into the atmosphere, the world would still feel at least an additional 0.5°F (0.3°C) of warming over this century, compared with today.  The projected actual rise, scientists say, will be as much as 2°C.

Costs 1

     Estimating damage costs from global warming (climate change) is difficult.  Estimated $ values cover a wide spectrum, depending on many assumptions, as well as on which effects are examined, over how long, for which geographical area, compounded by further uncertainties about how much carbon humans will emit how fast, positive feedbacks (e.g., less reflected sunlight when ice melts, more carbon emitted by thawing permafrost), and - most of all - what the warming effects will be for how much emissions, with what kind of lags in warming.  Assumptions about adaptation by farmers are a key factor.  Another key assumption is the discount rate.

     Water costs (esp. for agriculture and esp. in the West, mostly for desalination and recycling water) cope with drought and groundwater depletion.  Real estate losses are from sea level rise (45 inches by 2100).  Energy costs include increased cooling requirements, higher transmission thermal losses, and curtailed power production due to heat & drought.  Other impacts (food losses, health, etc.) not included.

US Inaction Could Cost $3.8 Trillion per Year by 2100 - 0506

$74 Trillion Cost of Climate Inaction - Watkiss 0905 - PDF, 88 pp, modeling by Chris Hope
    Estimated costs are based on FUND and PAGE Monte Carlo simulations.  Such simulations use many scenarios, based on multiple values (usually 2-5) for each of several (usually 5-20) key inputs. 

     The A2 scenario (see just below) is "business as usual", with high and rising CO2 concentrations.

These 3 graphs above show that expected damages are lower as emissions are lower.

     At left is William R. Cline’s 1992 estimate of damages in the US alone (his Table 3.4) from many of the same categories addressed by DARA, Ackerman & Stanton, and others.  (from The Economics of Global Warming.  Institute for International Economics, Washington DC, June 1992.  ISBN 0-88132-150-8)

     Note that the estimate is just for the US, not the world, as the DARA, Watkiss and "Climate Change to Cost 19% of World GDP by 2030 - 0909" estimates are.  Cline’s estimate is more comparable to Ackerman and Stanton’s - also for the US, but in 1990$ instead of 2006$.
     Cline’s estimated $61 billion in damages for 2.5°C warming may correspond to somewhere between the 2050 and 2075 damage estimates from Ackerman and Stanton. Thus, Cline's are a good bit lower, even though A & S examined only 4 sectors.  Cline’s estimate for those 4 sectors alone was about $60 billion in 2006$.  In retrospect, given the costs of recent US drought and hurricane damages, Cline’s estimates seem low.

The Selfish Case for Climate Justice 1022 - Wealthy countries can embrace an agenda that helps the most vulnerable parts of the world address catastrophic flooding, deadly famines, and unchecked migration — and in doing so help prevent destabilizing ripple effects.  Or wealthy countries can dismiss the concerns of their developing counterparts and hunker down to await the inevitable shock waves.
     Already, drought has uprooted communities in Central America, driving migrants to cities and, eventually, to the U.S.  Meanwhile, drought in Syria has contributed to the struggles driving over a million migrants from the war-torn country to Europe.  These movements of people have, respectively, stoked political upheaval in the U.S. and helped topple governments in Europe.
