Global warming: a perspective from earth history

Global climate change is increasingly recognised as the key threat to the continued development – and even survival - of humanity. In the below links, we give the context obtained from earth history, as the pattern of global environmental change in the past provides an indispensable context to establishing likely trajectories of future climate change. We find that the evidence for human-induced climate change is now persuasive, and the need for direct action compelling.

• Ice Age climate
• Our current interglacial
• Greenhouse gas records
• Cause and effect?
• Lessons from the deep past
• Consequences of climate change
• Ice sheets today
• Implications

We urge serious, and immediate, consideration of these issues. The dangers posed by climate change are no longer merely possible and long-term. They are probable, imminent, and global in scope.
