The report by the UN's climate panel details the physical evidence behind climate change.
On the ground, in the air, in the oceans, global warming is "unequivocal", it explained.
It adds that a pause in warming over the past 15 years is too short to reflect long-term trends.
The panel warns that continued emissions of greenhouse gases will cause further warming and changes in all aspects of the climate system.
To contain these changes will require "substantial and sustained reductions of greenhouse gas emissions".

After a week of intense negotiations in the Swedish capital, the summary for policymakers on the physical science of global warming has finally been released.
The first part of an IPCC trilogy, due over the next 12 months, this dense, 36-page document is considered the most comprehensive statement on our understanding of the mechanics of a warming planet.
It states baldly that, since the 1950s, many of the observed changes in the climate system are "unprecedented over decades to millennia".
Comment: As we are already tired of pointing out the obvious, we invite the reader to analyze international weather reports or just look out of the window and see for themselves if our world is warming, or actually on the brink of a new Ice Age. IPCC's continuous and deliberate lying to the public is nothing short of criminal and negligent. The so called scientists should be ashamed of intentionally misleading the public, and for allowing psychopaths in power to execute their soulless agenda.
