Volcanism caused ancient global warming

Punctuated Volcanism, Transient Warming and Global Change in the Late

Episodic warming of early Mars by punctuated volcanism

The widespread evidence for liquid water on the surface of early Mars is di cult to reconcile with a dimmer early Sun. Many geomorphological features suggestive of aqueous activity, such as valley networks and open-basin lakes, date to approximately 3.7 billion years ago1–5, coincident with a period of high volcanic activity5,6. This suggests that volcanic emissions of greenhouse gases could ha...

Global warming

The role of General Circulation Models (GCMs) has become predominantly important as the practical interest in regional impacts from anthropogenic greenhouse gases such as carbon dioxide (CO2) grows. This first report documents the quality of GCMs as a tool for describing and predicting ‘global warming’ and the related geographical pattern of climate change from the CO2 added to Earth’s atmosphere.
