Fifth Assessment Report (AR5)
AR5 provides a clear and up to date view of the current state of scientific knowledge relevant to climate change. It consists of three Working Group (WG) reports and a Synthesis Report (SYR).
Many aspects of climate change and associated impacts will continue for centuries, even if anthropogenic emissions of greenhouse gases are stopped. The risks of abrupt or irreversible changes increase as the magnitude of the warming increases.
If into the reasons for our procrastination you go, only pain will you find. Greed, denial, and delusion. Your science, save you it will not in a world of corruption and immediate profit.
