How 2 Degrees May Turn into 4
At the recent COP21 climate conference in Paris, delegates reached an agreement that plans to limit global warming to "well below" two degrees Celsius. This stems from the fact that scientists and politicians now agree: the global average temperature must rise by no more than two degrees if we are to prevent serious, irreversible damage to humans and the environment.
"However, this climate target is abstract and invites misunderstanding," says Sonia Seneviratne, Professor of Land-Climate Dynamics at ETH Zurich. According to Seneviratne, many people will interpret two degrees globally as two degrees of warming in their region and, accordingly, will not be proactive enough about reducing CO2 emissions in their countries.
The problem is that, according to various climate models, the temperature will rise more sharply over land than over oceans. The big question is therefore how a maximum of two degrees global warming will affect individual regions of the world.
