In both cases, there is substantial uncertainty about the things we most care about and in fact, in the case of climate change, Martin Weitzman's Dismal Theorem concludes that calculations of
the expected economic cost of climate change are dominated by the mathematical details of the low - probability / catastrophic - consequence tail of the probability distribution.

Another report by the German Institute
of Economic Research concluded that «If
climate policy measures are not introduced, global
climate change damages amounting to up to 20 trillion US dollars can be
expected in the year 2100... The
costs of an active
climate protection policy implemented today would reach globally around 430 billion US dollars in 2050 and around 3 trillion US dollars in 2100.»
Barring policies to curb GHG emissions, scientists
expect this problem to grow and eventually lead to
climate change and its accompanying
costs, including damage to
economic activity from the destruction
of capital (for example, along coastal areas) and lower agricultural productivity.
Among the
economic costs climate change is
expected to enact on the United States over the next 25 years are: $ 35 million in annual property losses from hurricanes and other coastal storms, $ 12 billion a year as a result
of heat wave - driven demand for electricity, and tens
of billions
of dollars from the corn and wheat industry due to a 14 percent drop in crop yields.
The impacts
of harmful algal blooms (HABs) in the Great Lakes are being assessed using a range
of economic metrics capturing the loss
of services provided by the lakes (e.g. increased drinking water treatment
costs, property value losses, beach closures), as well as the direct effects
of toxic microcystin on public health (Bingham et al 2015, IJC 2013)-- such events are
expected to increase in frequency and severity in a
changing climate (Michalak et al 2013).
