Washington — A new international draft report says global warming is here, human-caused and can already be considered dangerous. The report warns that it is increasingly likely that climate change could be irreversible.

The United Nations' Intergovernmental Panel on Climate Change on Monday sent governments a draft of its final synthesis report, which combines three earlier, gigantic documents by the Nobel Prize-winning group.

The 127-page draft, obtained by The Associated Press, paints a stark warning of what's causing global warming — burning fossil fuels — and what it will do to humans and the environment. It also describes what can be done about it.

The report said the climate changes that have already occurred are widespread and consequential, while the human fingerprints on the problem are clear and unequivocal.
