1.Nuclear power could at most provide a very partial solution to climate change. Few predict a doubling of nuclear power output by 2050, but even if that happened, greenhouse gas emissions would only be reduced by about 5% – less than one tenth of the reductions required to stabilise atmospheric concentrations of greenhouse gases. Nuclear power is used almost exclusively for eletricity production, which accounts for less than one third of (human) greenhouse emissions. Over two thirds of greenhouse emissions arise from other sectors (e.g. transport, agriculture/land clearing, industry, residentia 2.The nuclear cure would be as bad as the disease, with increased nuclear weapons proliferation and unresolved waste management problems.
