• The UN's climate science panel today published its report on what impacts climate change is having on humans and the natural world, and what effects we can expect in the decades to come. “Nobody on this planet is going to be untouched by the impacts of climate change,” said Rajendra Pachauri, chair of the IPCC.

• Food supplies will be affected as yields from major crops including wheat, maize and rice decrease

• The report is clear that the poor will suffer most, and that rising temperatures could set back efforts for developing countries to climb out of poverty

• Al Gore says the report should serve as a call to action: "The consensus is clear. We need an immediate and determined shift to a clean, renewable economy," he said in response to the IPCC report.

• There's been a 'row' between one of the 70-strong writing team behind the report, Richard Tol, and the co-chair of the group that produced the report, Chris Field. Tol pulled out of the writing process, saying drafts were too "alarmist". Field said: "When you get an IPCC report, you see the position of the scientific community." He joked: "Every IPCC author thinks the report would be a lot better if it put more emphasis on his or her work."

• Field told the BBC's Today programme that report shows that "the risk of severe and pervasive impacts goes up dramatically in a world that doesn't pay attention to high emissions"
