IPCC report warns greenhouse gas levels at highest point in 800,000 years, identifies fossil fuels as cause of recent increases

The world's top scientists have given their clearest warning yet of the severe and irreversible impacts of climate change.

The United Nations Intergovernmental Panel on Climate Change (IPCC) has released its synthesis report, a summary of its last three reports.

It warns greenhouse gas levels are at their highest point in 800,000 years, with recent increases mostly due to the burning of fossil fuels.

"Continued emission of greenhouse gases will cause further warming and long-lasting changes in all components of the climate system, increasing the likelihood of severe, pervasive and irreversible impacts for people and ecosystems," the report said.

"Limiting climate change would require substantial and sustained reductions in greenhouse gas emissions which, together with adaptation, can limit climate change risks."

One of the authors, Professor Jim Skea, said the document would be invaluable in future climate change negotiations.

"The statements are much more powerful because they're put together," he said.

"The inferences that you can draw are just very obvious for policymakers now and I think what the achievement is."

Australian oceans expert John Church was in Copenhagen to negotiate the final wording of the report.

Dr Church was the coordinating lead author of the sea levels chapter and said warming of the climate system is "unequivocal".

"There's many components - increasing surface temperature, melting glaciers, increasing ocean heat content, ice sheets losing mass, sea level rising," he said.

"It's very clear that there's a human component that's contributed significantly to that with rising impacts across many regions."

The document will be an invaluable summary for climate negotiations for emission reduction targets post-2020.

Governments will meet in Peru this year as part of the United Nations Framework Convention on Climate Change annual meeting.

Targets are expected to be finalised at the 2015 negotiations in Paris, but the Peru conference will serve as an important step forward in setting the framework.

Huge bushfires in Oct–Nov and you still can’t open your eyes to see AGW is here and now?

The left coast of the US had a really bad fireseason their summer just past. California is in a deep drought. And so it goes.

What the flip is that supposed to mean?

We are not talking about rain and rainbows. We are talking about setting up our civilisation for collapse.

Greens are conservatives not commies.

We see AGW posing a huge problem, the only ones wanting or bringing about a collapse of civilisation are the frightened little numpties trying to pretend there isn’t a problem.

Imagine if it is one big hoax, and we make world a better place, for nothing.

Climate science based facts is not a religion. Denial of climate science is.

The only reason you deny the science is because you, and only you dug your hole and dammed humanity.

So you quote nonsense to support your nonsense. Your lobotomy was quite successful.
