An open letter to Ban Ki Moon from 140 scientists on why the science of climate change is not settled

Specifically, we challenge supporters of the hypothesis of dangerous human-caused climate change to demonstrate that:

Variations in global climate in the last hundred years are significantly outside the natural range experienced in previous centuries;

Humanity’s emissions of carbon dioxide and other ‘greenhouse gases’ (GHG) are having a dangerous impact on global climate;

Computer-based models can meaningfully replicate the impact of all of the natural factors that may significantly influence climate;

Sea levels are rising dangerously at a rate that has accelerated with increasing human GHG emissions, thereby threatening small islands and coastal communities;

The incidence of malaria is increasing due to recent climate changes;

Human society and natural ecosystems cannot adapt to foreseeable climate change as they have done in the past;

Worldwide glacier retreat, and sea ice melting in Polar Regions , is unusual and related to increases in human GHG emissions;

Polar bears and other Arctic and Antarctic wildlife are unable to adapt to anticipated local climate change effects, independent of the causes of those changes;

Hurricanes, other tropical cyclones and associated extreme weather events are increasing in severity and frequency;

Data recorded by ground-based stations are a reliable indicator of surface temperature trends.
