In this paper it is shown that climate models are characterized by uncertainty and its causes are pointed out. It is well known that a higher greenhouse gas concentration raises the radiative forcing of the earth and the physics behind it is well understood. However, as regards the feedback...

In this paper we show that both climate models and economic models studying the effects of climate change are characterized by high uncertainty. Hence, far reaching policy implications such as the net zero goal lack a definite scientific foundation. Neverthelss, it cannot be excluded that the...
