Economic consequences of Global Warming

Calculations of the economic impact of global warming are very difficult to make. Some economists speak of a cost of two euros per tonne of carbon, whereas others suggest 50 euros. Among the various figures put forward, one estimates that global warming might cost up to one percentage point of economic growth. It is worth noting that banks, insurance companies, farmers and developing countries are likely to be the most exposed. However, depending on the capacity of adaptation shown by the economy and by political organisations and on possible technological revolutions triggered by the challenge of climate change, a more optimistic outlook is not to be entirely excluded.
